AGRICULTURAL CHEMICAL USAGE Overview This report is the second annual Field Crops Summary issued by the National Agricultural Statistics Service (NASS) containing on-farm agricultural chemical use statistics. The data presented in this report are part of the data series on chemical use funded through the President's Water Quality Initiative. The Water Quality Initiative is a multi-agency program designed to provide information for farmers, ranchers, and foresters to address on-farm and off- farm environmental issues. In the past, there has been an inadequate amount of farm level data to determine the magnitude of water quality problems or to permit an assessment of alternatives for farmers and other affected parties. This report and other agricultural chemical reports help fill the needs of analysts evaluating the complex environmental issues of the 1990's. NASS is responsible for collecting on-farm agricultural chemical use information to support the evaluation of water quality and food safety issues. The Economic Research Service (ERS) conducts research on the impact of alternative pesticide regulations, policies, and practices. This report includes farm use of fertilizers and pesticides during 1991 on corn, cotton, peanuts, potatoes, rice, sorghum, soybeans, and wheat. New in this year's report is pesticide and fertilizer usage on peanuts and sorghum. In 1991, changes were made to the sample sizes and the number of States surveyed for some crops. The table below compares survey coverage for 1990 with 1991 by crop. In it are the number of States surveyed, the number of reports summarized, and the percent of the U.S. crop acres accounted for in the surveyed States.

Chemical use data were collected on winter wheat beginning in late May 1991, while data collection for the other crops began in late July 1991. Generally, data were collected late in the growing season or after the farm operator indicated planned applications were completed. A random sample of fields was selected for each crop so that the probability of selecting a particular field was directly proportional to the total acres planted to that crop. Thus, each acre planted to a crop had exactly the same chance of selection. For winter wheat, the selection was based on acres standing for harvest rather than acres planted. Sample fields were selected using information obtained through two surveys of farm operators conducted earlier in the year. The survey of winter wheat acreage was conducted in March. For other crops, small areas of land, called segments, were surveyed in June throughout the country to determine which crops were planted. These segments served as the basis from which sample fields were selected. Farmers operating the sample fields were personally interviewed to obtain information on chemical applications made to those specific fields. The survey instrument was used to collect chemical application data by product name or trade name. A thorough review compared reported data with manufacturer's label recommendations and with data from other farm operators using the same product. Following this review, product information was converted to an active ingredient level. The chemical use estimates in this publication consist of survey estimates of those active ingredients. HIGHLIGHTS Nitrogen was applied to 96 percent of the corn acreage while phosphate and potash on 81 and 71 percent, respectively. Approximately 94 percent of the corn acreage received one or more applications of herbicides and 30 percent received applications of insecticides. Cotton producers applied nitrogen fertilizers to 81 percent of the acreage planted. Phosphates were put on 52 percent of the acres and potash on 34 percent of all upland cotton planted. Herbicides were used on about 91 percent of the cotton acres while insecticides went on over two-thirds of the acreage. Nitrogen was applied to 69 percent of the peanut crop planted across the four surveyed States. Phosphate and potash use was higher with both fertilizers being applied to 79 percent of the acreage. Herbicides were applied to 97 percent of the acreage in the four States. Insecticides went on 56 percent of all planted acres in these States, and fungicides were applied to 89 percent of the crop. Potato acres receiving at least on application of nitrogen totaled 99 percent. Phosphate was just as widely used as 98 percent of the crop received that fertilizer while potash applications dropped to 87 percent of the crop acres. Herbicides were applied to 79 percent of the acreage; insecticides went on 91 percent of the acres; fungicides went on 69 percent of the acres; and other chemicals were applied to 45 percent of the crop in the States surveyed. Rice producers in Arkansas and Louisiana made one or more applications of nitrogen to 99 percent of their acreage, phosphate to 32 percent, and potash to 34 percent. About 95 percent of the acreage was treated with herbicides, 16 percent insecticides, and 24 percent fungicides. Sorghum producers in the three States surveyed used nitrogen on 86 percent of the crop while phosphate went on 44 percent. Potash was used in limited amounts, being applied to only 11 percent of the crop. Herbicides were the major pesticide used as they were applied to 78 percent of the area planted. Only 16 percent of the crop was treated with insecticides. Nitrogen was used on 16 percent of the soybean acreage, phosphate 22 percent, and potash 23 percent. Herbicides were applied to about 96 percent of the soybean acreage, but only 2 percent received applications of insecticides. Winter Wheat producers in the States surveyed applied nitrogen to 84 percent of the harvested area, phosphate to 50 percent, and potash to 19 percent. Approximately 28 percent of the acreage was treated with one or more applications of herbicides and 6 percent insecticides. Other Spring Wheat acreage in the States surveyed received one or more applications of nitrogen on 72 percent, phosphate on 63 percent, and potash on 23 percent of the planted acreage. Herbicides were used on approximately 92 percent of the acreage and insecticides on only 3 percent. Durum Wheat acreage in North Dakota received at least one application of nitrogen on 72 percent, phosphate on 63 percent, and potash on 7 percent of the planted area. Herbicides were applied to 94 percent of the acreage and insecticides to 6 percent. Corn Nitrogen was applied to 96 percent of the total 1991 corn acreage in the States surveyed. Most of the major producing States included in the survey showed that 90 percent or more of the acreage had been treated. The exceptions were Texas with 66 percent and South Dakota with 83 percent. The number of treatments averaged 1.7, with only two States, North Carolina and Ohio, averaging more than 2 treatments per acre. Rates per application were highest in Missouri and lowest in Wisconsin. The average rate per application was 74 pounds. Phosphate use varied by State with a low of 41 percent in Texas to a high of 96 percent in North Carolina. Overall, 81 percent of the corn acreage in the States surveyed received phosphate fertilizer. Seventy-one percent of the corn acreage in the survey received potash fertilizer. Potash use varied widely, only 13 percent in Texas, but 96 percent in North Carolina. Herbicides were applied to 94 percent of the total acreage in the survey, while insecticides were used on only 30 percent of the acreage. Atrazine was the most used herbicide with 66 percent of the reported acreage being treated. The average application rate was 1.1 pounds per acre. The next most widely used herbicides were metolachlor and alachlor and each was applied to about 30 percent of the acreage. The following U.S. map shows the number of usable reports by State included in the 1991 survey. These States represent 68.6 million acres of corn and 90 percent of the total corn acres planted in the U.S. in 1991. The bar chart shows the top 5 active ingredients applied in 1991 compared with 1990.

Source: "Crop Production" 1991 Summary and Agricultural Chemical Usage Survey. National Agricultural Statistics Service, USDA. Upland Cotton Nitrogen fertilizer was applied on 81 percent of the Upland Cotton acres in the six States surveyed. Five States treated at least 90 percent of the acreage, and Texas treated 70 percent of the acreage. About 1.7 treatments per acre were applied. Phosphate use covered 52 percent of the acreage. Arkansas, at 70 percent, treated the largest percent of acres with phosphate, and the least amount was in California with 35 percent of the acreage treated. Potash use was the highest in the Delta States (Arkansas, Louisiana, and Mississippi) compared with the Western States (Arizona, California, and Texas). Herbicides were applied to 91 percent of the Upland Cotton acreage in 1991. Trifluralin was applied to 63 percent of planted acres, nearly unchanged from one year ago. Information concerning insecticides, fungicides, and other chemicals, was collected for the first time during this survey. Insecticides were applied to slightly more than two thirds of the acreage in 1991, while 6 percent of Upland Cotton acreage received treatment of fungicides and 58 percent was treated with other chemicals. The following U.S. map shows the number of usable reports by State included in the 1991 survey. These States represent 10.9 million acres of upland cotton which is 78 percent of the total upland cotton acres planted in the U.S. in 1991. The bar chart shows the top 5 active ingredients applied in 1991 compared with 1990.

Source: "Crop Production" 1991 Summary and Agricultural Chemical Usage Survey. National Agricultural Statistics Service, USDA. Peanuts Four peanut producing States, Georgia, North Carolina, Virginia, and Texas were included in the 1991 survey. These States represent nearly 1.5 million acres or 73 percent of the U.S. total planted acres. Data were collected on the use of fertilizer, herbicides, insecticides, fungicides, and other chemicals. Nitrogen was applied to 50 percent of the acreage in the North Carolina- Virginia region and to 81 percent of the Texas acreage. Application rates were similar in Georgia, North Carolina, and Virginia while Texas application rates were higher. Phosphate use varied across the four States from 59 percent of the acreage in North Carolina-Virginia to 86 percent in Georgia being treated. The application rates were uniform across all States. Potash was used on 65 percent of the acreage in Texas and 86 percent of the area in Georgia. Application rates for potash ranged from 35 pounds per acre in Texas to 93 pounds per acre in North Carolina and Virginia. Herbicides were applied to 97 percent of the acreage in 1991 in the four States. Insecticide were applied to 56 percent of the acreage while fungicides were used on 89 percent of the area. Herbicide and insecticide materials varied widely across the States due to different pests while fungicide usage was more uniform with Chlorothalonil emerging as the most prevalent material in all States. The U.S. map shows the number of usable reports by State included in the 1991 survey. The tables show combined data for North Carolina and Virginia as the growing region is one contiguous area for both States. The bar chart shows the top 5 active ingredients reported in the survey.

Fall Season Potatoes Nitrogen was applied to 99 percent of the fall season potato acres in the 11 States surveyed. Oregon growers applied nitrogen on 93 percent of the crop, but in the seven other States put it on all planted acreage. Producers in the surveyed States averaged over 2 applications of nitrogen. Rates were lowest in Minnesota and highest in Washington. Phosphate was as widely used. Phosphate was applied to 98 percent of the acres in the surveyed States; however, Oregon growers applied it on only 91 percent of the crop. The smallest number of applications was reported in New York and Maine, while the largest number of applications was reported in Oregon. The lowest rate applied per crop year was reported in Minnesota, and the highest rate was in Washington. Potash was applied to 87 percent of the acres in the 11 States surveyed. New York reported the fewest number of applications and Wisconsin the highest. Colorado reported the lowest rate per crop year and Wisconsin the highest. Herbicide use ranged from 46 percent of the acres treated in Minnesota to 100 percent of the acreage in New York. Insecticide use was lowest in Colorado where 61 percent of the acreage was treated. Producers in all of the other States applied insecticides to 88 percent or more of the potato acreage. Number of treatments and application rates varied greatly between States. Acres treated with fungicides ranged from 37 percent in Idaho to 100 percent in New York. Information on 12 different herbicides, 26 insecticides, 15 fungicides, 4 desiccants, 2 soil fumigants, and 2 growth regulators was collected in the survey. The U.S. map shows the number of usable reports by State included in the 1991 survey. These States represent 1.1 million acres of fall season potatoes planted or 94 percent of the total fall season potatoes planted in the U.S. in 1991. The bar chart shows the top 5 active ingredients applied in 1991 compared with 1990.

Rice Nitrogen application practices were similar in Arkansas and Louisiana, while application of phosphate was limited to 10 percent of the acres in Arkansas compared to 82 percent in Louisiana. A similar relationship exists with potash application, highlighting the differences in soil conditions between the two States. Herbicide use was widespread in both States while insecticides and fungicides were used less frequently. Harvest aids were rarely used. Insecticides were applied to 16 percent of the acreage and fungicides were applied to 24 percent. Pesticide application practices in the two States were generally similar. The U.S. map shows the number of usable reports by State included in the 1991 survey. Arkansas and Louisiana represent 1.86 million acres of rice acres planted or 65 percent of the total rice acres planted in the U.S. in 1991. The bar chart shows the top 5 active ingredients applied in 1991 survey compared to 1990.

Kansas and Nebraska reported 90 and 91 percent of the acreage receiving nitrogen at 53 and 56 pounds per acre respectively. Phosphate use was less widespread than nitrogen. Texas reported 48 percent of the acreage receiving phosphate, Kansas 47 percent and Nebraska 27 percent. Potash use in the surveyed States was sparse. Kansas and Texas reported potash applied to 13 percent of the acreage. Each of these two States averaged one application per treated acre at the rates of 27 pounds per acre in Kansas and 19 pounds per acre in Texas. Nebraska did not report enough potash use to make the application information publishable. Herbicide use in the surveyed States was reported on 91 percent of the acreage in Nebraska, 80 percent in Kansas, and 70 percent in Texas. Insecticide use was much less prevalent than herbicide use. Texas reported the highest percent of acreage receiving an insecticide at 29 percent. Kansas reported nine percent of the acreage receiving an application, and Nebraska reported six percent. The U.S. map shows the number of usable reports and States included in the 1991 survey. These States represent 8.1 million acres of sorghum planted or 73 percent of the total sorghum acres planted in the U.S. in 1991. The bar chart shows the top 5 active ingredients from the 1991 survey.

Soybeans In the 16 major soybean States surveyed, nitrogen was applied to 16 percent of the area planted. The acres treated in Louisiana were only 3 percent of the total while Georgia growers applied nitrogen on 55 percent of the total planted acres. The average number of nitrogen applications was 1.1 and the average rate per application was 23 pounds per acre. Application rates were lowest in Indiana, Nebraska, and Ohio and highest in Iowa and Kentucky. Phosphate was applied on 22 percent of the planted area in the major States. Georgia growers applied phosphate to 63 percent of the soybean acreage while in Iowa and Louisiana, applications covered less than 10 percent of the planted acreage. Illinois and Kentucky had the highest application rates and Nebraska had the lowest. Potash applications were similar to phosphate in terms of the percent of acreage receiving an application. The heaviest potash application rates were in Georgia, Illinois, North Carolina, and Ohio. Nebraska had the lowest application rate. In the sixteen States surveyed, an average of 96 percent of the soybean acreage were treated with herbicides. Trifluralin was applied to over one-third of the acreage and imazethapyr was applied on one-fourth of the acreage. Growers in eleven out of the sixteen States surveyed reported applications of insecticides. Georgia, Louisiana, and North Carolina producers reported the highest percent of acres receiving one or more insecticides. Producers in only six out of the sixteen States reported fungicide applications. Estimates for only a few insecticides and fungicides are published separately due to insufficient reports. The U.S. map shows the number of usable reports by State included in the 1991 survey. The States represent 53.2 million acres of soybeans which is 90 percent of the soybeans planted in the U.S. in 1991. The bar chart shows the top 5 active ingredients used in 1991 compared to 1990.

Winter Wheat About 84 percent of the winter wheat acres in the 15 States surveyed was treated with nitrogen fertilizer. Colorado and South Dakota were the only States where growers treated less than 70 percent of the acres harvested. The average number of applications was 1.5 and averaged 43 pounds per application. Phosphate fertilizer was used in all States surveyed, with about 50 percent of the acreage being treated. The percent coverage was above 90 percent in Illinois and Ohio, but was only 11 percent in Oregon. The average number of applications and pounds per application was 1.0 and 39, respectively. Potash was used on 19 percent of the acreage in the 15 State area, with producers in Soft Red Winter States treating the highest percentages. Producers in all surveyed States treated some portion of their harvested area with herbicides; 2,4-D was the most prevalent. Percentage of acreage treated with herbicides was highest in the Pacific Northwest and Montana. Insecticide and fungicide use on winter wheat was low overall. Other Spring Wheat The percent of acres treated with fertilizer in the 4 States surveyed averaged 72, 63, and 23 percent for nitrogen, phosphate, and potash, respectively. Minnesota had the highest percent of area treated for all three primary plant nutrients. Herbicides were widely used in all States; none had less than 85 percent of the planted area treated, 2,4-D was the most used. Insecticide and fungicide applications were limited. Minnesota had the highest percent of area treated by these chemical groups. Durum Wheat North Dakota was the only durum wheat producing State surveyed. Fertilizer and Herbicide treatments were similar to those shown for other spring wheat. The U.S. map shows the number of usable reports for winter wheat, durum wheat, and other spring wheat and the States included in the 1991 survey. The winter wheat producing States represent 34.1 million acres or 87 percent of the total winter wheat harvested in the U.S. North Dakota was the only durum wheat State included in the survey and represents 2.9 million acres or 89 percent of the total planted acres. The other spring wheat States represent 13.5 million acres or 87 percent of the total planted acres. Three bar charts show the top 4 or 5 active ingredients applied in 1991.

Reliability Statement The probability nature of the survey provides expansion of data so that the estimates are statistically representative of chemical use on the targeted crops in the surveyed States. A complete census may have yielded different results. The reliability of these survey results are affected by sampling variability and non-sampling errors. The variability due to sampling was computed for all the chemical and acreage variables in the survey, and is expressed as a percentage. To interpret its meaning, imagine that the survey is repeated many times using the same sample size. For every two out of three times the survey is repeated, the results woul not differ from those published here by more than the stated sampling variability. Sampling variability of the estimates differed considerably by chemical and crop In general, the more often the chemical was applied, the smaller the sampling variability. The following table show the range of sampling variability for percent of acres treated and for application rate. The variability ranges in the table can be used to calculate approximate confidence bands for figures in the data tables of the report. For example, if a figure in the report is 30 percent of acres treated by a fertilizer, the confidence band for acres treated for a State with a small sample size would be 30 - .20*30 to 30 + .20*30 or 24 to 36 percent. For a State with a large sample size; the confidence band would be 30 - .05*30 to 30 + .05*30 or 28.5 to 31.5 percent.

Fertilizer in this report refers to applications of nitrogen, phosphate, and potash. Pesticides include any substance or mixture of substances intended for preventing, destroying, repelling or mitigating any pest, and any substance or mixture of substances intended for use as a plant regulator, defoliant, or desiccant. Pests targeted by pesticides includes weeds, insects, fungi, and other forms of life. Herbicides, insecticides, fungicides, and other chemicals make up the four classes of pesticides presented in this report. Miticides and nematicides are included as insecticides while soil fumigants, growth regulators, defoliants, an desiccants are included as other chemicals. This report excludes the use of see treatments, post-harvest applications to the commodity, and spot treatments. Active ingredient is the specific chemical which kills or controls the target pests. Pesticide products reported are converted to an amount of active ingredient in the summary program. Some active ingredients have more than one way of being converted. For example in this report, copper compounds are expressed in their metallic copper equivalent, glyphosate in the form of its isopropylamine salt, and others such as 2,4-D in their acid equivalent. Trade name is the actual product name given to a specific formulation of a pesticide product. A formulation contains a specific concentration of the activ ingredient, carrier materials, and other ingredients such as emulsifiers and wetting agents. Some formulations as in the case of pre-mixes, can contain more than one active ingredient. The published active ingredient name is called the common name. Rate per application refers to the average number of pounds of a fertilizer ingredient or pesticide active ingredient applied to an acre of land in one application. Rate per crop year is the average number of pounds applied of an ingredient to one acre of land counting multiple applications. Number of applications is the average number of times a treated acre receives a specific agricultural chemical. Area applied represents the percent of crop acres receiving one or more applications of a specific ingredient. This report does not contain acre treatments. However, they can be calculated by multiplying the acres planted by the percent of area applied and times the average number of applications. Trade Names, Common Names, and Classes The following is a list of common names of active ingredients with the associate class and trade name. The classes are herbicides (H), insecticides (I), fungicides (F), and other chemicals (O). This list is provides as an aid in reviewing pesticide data. Pre-mixes are not listed. The list is not complete and NASS does not mean to imply use of any specific trade name. ------------------------------------------------------------------------------ Class : Common Name : Trade Name ------------------------------------------------------------------------------ H 2,4-D several H 2,4-DB Butoxone, Butyrac I abamectin Agri-Mek, Zephyr I acephate Orthene H acifluorfen Blazer, Tackle H alachlor Lasso I aldicarb Temik H,O ametryn Evik I amitraz Mitac F anilazine Dyrene O arsenic acid Desiccant L-10 H atrazine AAtrex I azinphos-methyl Guthion H barban Carbyne F basic copper sulfate Cuproxat, Top Cop, Tri-Basic H benefin Balan F benomyl Benlate H bensulfuron-methyl Londax H bentazon Basagran, Pledge H bifenox Modown I bifenthrin Capture H bromoxynil Buctril, Brominal I Bt (Bacillus thuringiensis) several H butylate Genate, Sutan O cacodylic acid Bolls-Eye, Cotton-Aide I carbaryl Sevin, Savit I carbofuran Furadan I carbophenothion Trithion F carboxin Vitavax H chloramben Amiben H chlorimuron-ethyl Classic F chlorothalonil Bravo H chlorpropham Furloe I chlorpyrifos Lorsban, Dursban H chlorsulfuron Glean H clomazone Command H clopyralid Stinger F copper ammonium Copper-Count-N F copper hydroxide several F copper resinate Tenn-Cop I cryolite Kryocide H cyanazine Bladex I cyfluthrin Baythroid I cypermethrin Ammo, Cymbush ------------------------------------------------------------------------------ -- continued ------------------------------------------------------------------------------ Class : Common Name : Trade Name ------------------------------------------------------------------------------ O cytokinins Triggrr, Burst F DCNA Botran, Sclerban H DCPA Dacthal H diallate Avadex I diazinon several H dicamba Banvel O dichloropropene Telone H diclofop-methyl Hoelon I dicofol Kelthane I dicrotophos Bidrin H difenzoquat Avenge O dimethipin Harvade I dimethoate several O diquat diquat I disulfoton Di-Syston H diuron Karmex, Direx H DSMA DSMA I endosulfan Thiodan O endothall Des-I-Cate, Accelerate H EPTC Eptam, Eradicane, Genep I esfenvalerate Asana H ethalfluralin Sonalan, Curbit O ethephon Ethrel, Prep I ethoprop Mocap I ethyl parathion several F etridiazole etridiazole I fenamiphos Nemacur H fenoxaprop-ethyl Whip, Option H fluazifop-P-butyl Fusilade I flucythrinate Pay-Off H fluometuron Cotoran, Meturon H fomesafen Reflex I fonofos Dyfonate H glyphosate Roundup, Ranger, Rodeo H imazamethabenz Assert H imazaquin Scepter H imazethapyr Pursuit F iprodione Rovral H lactofen Cobra I lambdacyhalothrin Karate H linuron Lorox, Linex I malathion several O maleic hydrazide Royal MH-30, Super Sprout Stop F mancozeb several F maneb several H MCPA several O mepiquat chloride Pix F metalaxyl Ridomil O metam-sodium Vapam I methamidophos Monitor H methazole Probe I methidathion Supracide I methomyl Lannate I methoxychlor several O methyl isothiocyanate Vorlex I methyl parathion several F metiram Polyram ------------------------------------------------------------------------------ -- continued ------------------------------------------------------------------------------ Class : Common Name : Trade Name ------------------------------------------------------------------------------ H metolachlor Dual H metribuzin Sencor, Lexone H metsulfuron-methyl Ally I mevinphos Phosdrin, Duraphos H molinate Ordram H MSMA several H naptalam Alanap H nicosulfuron Accent H norflurazon Solicam, Evital, Zorial H oryzalin Surflan I oxamyl Vydate I oxydemeton-methyl Metasystox-R H oxyfluorfen Goal H,O paraquat Gramoxone, Cyclone, Starfire F PCNB Terraclor H pendimethalin Prowl I permethrin Ambush, Pounce I phorate Thimet I phosmet Imidan I phosphamidon phosphamidon H picloram Tordon I piperonyl butoxide Butacide, PBO-8, Incite H primisulfuron Beacon I profenofos Curacron H prometryn Caparol, Cotton-Pro H propachlor Ramrod H propanil Stam I propargite Comite, Omite H propazine Milogard F propiconazole Tilt, Banner, Orbit H quinclorac Facet H quizalofop-ethyl Assure I rotenone rotenone H sethoxydim Poast H simazine Princep O sodium chlorate several I,F sulfur several O sulfuric acid sulfuric acid I sulprofos Bolstar I tefluthrin Force I terbufos Counter H terbutryn Igran F thiabendazole Mertect O thidiazuron Dropp H thifensulfuron methyl Pinnacle H thiobencarb Bolero I thiodicarb Larvin F thiophanate-methyl Topsin I tralomethrin Scout F triadimefon Bayleton H triallate Far-Go H tribenuron-methyl Express O tribufos Def, Folex H triclopyr Rely H tridiphane Tandem H trifluralin Treflan, Trilin, Trific I trimethacarb Broot F triphenyltin hydroxide several H vernolate Vernam ------------------------------------------------------------------------------ Index Page Table Narrative Corn...................................................
