Ag Chem 1 (01) United States Department of Agriculture National Agricultural Statistics Service Agricultural Chemical Usage 2000 Sheep and Sheep Facilities May 2001 2000 Agricultural Chemical Use Estimates for Sheep and Sheep Facilities Overview: The agricultural chemical use estimates in this report are based on data compiled from a survey conducted in late December 2000 through January 2001 in 22 selected States. These States account for approximately 87% of the U.S. sheep inventory published by NASS. Only those States with published sheep inventory for January 1, 2001 were used for this calculation. This report provides insecticide use information on sheep and sheep facilities in the 22 selected States. All data refer to the on-farm use of chemical active ingredients contained in insecticides which were applied during the 2000 calendar year. Insecticides are defined as chemical products used for the control of insects. Insecticides are regulated by the Environmental Protection Agency (EPA) and the Food and Drug Administration (FDA). Insecticides are applied to sheep and sheep facilities to control mange, mites, lice, flies, keds, bots, and other external pests. Chemical usage on sheep is provided on a rate per head per application and rate per head per year basis. Some sheep received no chemical applications in 2000; whereas, other sheep and lambs received multiple applications of the same chemical. In other cases, sheep received applications of several different chemicals. The number of times a chemical is applied varies significantly based on product formulation, method of application, and pest stress at particular locations. The rate per head data cannot be used to calculate the actual number of head treated with a particular chemical. Sheep and lamb inventories are reprinted in this report from a previous NASS release. This table is included for informational purposes only. Some active ingredients, such as petroleum distillate, piperonyl butoxide, and xylene are primarily carriers, diluents, synergists, or repellents. These active ingredients are classified by the EPA as pesticides, and are therefore included in this report. This report excludes pharmaceutical products that treat sheep for internal pests. A pharmaceutical is classified as a drug and is regulated by FDA. Pharmaceuticals generally target internal livestock pests such as viruses, bacteria, or worms. Some products can be classified as either a pesticide or a pharmaceutical because they treat both external and internal pests. Examples of dual purpose products are Doramectin and Ivermectin. These products can be applied to sheep internally through oral dosage or injection, or applied externally as a pour-on. Besides pharmaceuticals, disinfectants and sanitizers are also excluded. Only insecticide data were collected and summarized. This survey collected data for insecticides and chemical products that were applied to control external pests. Insecticide use information on chemical applications made to sheep facilities is also included in this report. For survey purposes, lambing sheds, sun-shades, lean-to's, and feedlots are examples of sheep facilities. Herbicide and termite chemical applications are excluded, as are all rodenticides. States Participating in the 2000 Sheep Chemical Use Study were Arkansas, California, Colorado, Idaho, Illinois, Indiana, Iowa, Kansas, Minnesota, Montana, Nevada, New Mexico, Ohio, Oregon, Pennsylvania, South Dakota, Texas, Utah, Virginia, Washington, Wisconsin, and Wyoming. Highlights All Sheep: Agricultural producers applied 14,191 pounds of insecticides to sheep and lambs during 2000 in the 22 surveyed States. Fenvalerate, at 5,444 pounds, was the top active ingredient used on sheep with respect to total quantity used, followed by malathion, at 3,940 pounds, and permethrin, at 1,749 pounds. These three active ingredients accounted for 78 percent of the total pounds of active ingredients applied to sheep and lambs in the surveyed States during 2000. Of the total chemical applications made to sheep in 2000 in the 22 selected States, 46 percent were applied as a pour-on, 25 percent by injection, 11 percent by hand spray, 10 percent by power spray, and 5 percent through oral drench. Insecticide applications made to sheep through mineral or feed block and dust bags each accounted for 1 percent. All other methods accounted for the remaining 1 percent of the chemical applications. All Sheep Facilities: In the 22 surveyed States, a total of 4,984 pounds of insecticides was applied to sheep and lamb facilities in 2000. Petroleum distillate had the highest quantity used at 3,180 pounds. Malathion had the second highest quantity used at 935 pounds, followed by permethrin at 248 pounds. These three active ingredients accounted for 88 percent of the total pounds of active ingredients applied to sheep facilities in the surveyed States during 2000.

Survey Procedures: The estimates in this report are based on the 2000 National Animal Health Monitoring System (NAHMS) Sheep Survey conducted in January 2001. This survey was based on a sample of pre-screened operators reporting sheep data on a previous NASS survey. Enumerators conducting the survey collected a variety of information including insecticide applications to sheep and sheep facilities for respondents' entire operations. Data were collected in the State where the operation's headquarters was located. Estimation Procedures: The chemical application data, reported by product name or trade name, are reviewed within States and across States for reasonableness and consistency. This review also compares reported data with manufacturers' recommendations and with data from other livestock operators using the same product. Following this level of review, each reported product is then converted to an active ingredient level. This conversion is calculated based on composition and concentration of active ingredients in each product. The chemical usage estimates in this publication consist of survey estimates of those active ingredients. Data in this report are published at the U.S. level only. Detailed data within a table may not sum to totals due to independent rounding of published values. Reliability: The survey was designed so that the estimates are statistically representative of chemical use on sheep and sheep facilities. The reliability of these survey results is affected by sampling variability and non-sampling errors. Sampling variability is a measure of how the estimates would differ if other samples had been drawn. The sampling variability expressed as a percent of the estimate is called the coefficient of variation (cv). Sampling variability of the estimates differed considerably by chemical. In general, the more often the chemical was applied, the smaller the sampling variability. For example, estimates of use of a commonly used product, such as ivermectin, will exhibit less variability than a more rarely used product. For more commonly used chemicals, cv's will range from 10-50 percent at the U.S. level. Some rare items could have cv's above 100 percent. These rare items have an insufficient number of reports for publication and are noted with an asterisk (*). Non-sampling errors occur during a survey process, but unlike sampling variability, are difficult to measure. They may be caused by interviewers failing to follow instructions, poorly worded questions, non-response, problematic survey procedures, or data handling mistakes between collection and publication. In this survey, all survey procedures and analyses were carried out in a consistent and orderly manner to minimize the occurrence of these types of errors. Terms and Definitions Active ingredient: The active ingredient is the specific chemical which kills or controls the target pests. Usage data are reported by pesticide product and are converted to an amount of active ingredient. Agricultural chemicals: The phrase, "agricultural chemicals," refers to the active ingredients in pesticides. Application rates: The application rates refer to an average weight of a pesticide active ingredient applied to a volume of product. For this survey, rate per application is the average number of grams applied in one application. Rate per year is the average number of grams applied counting multiple applications. Carrier: An inert liquid, solid, or gas added to an active ingredient to make a pesticide dispense effectively. A carrier is also the material, usually water or oil, used to dilute the formulated product for application. Common name: The common name is an officially recognized name for an active ingredient. This report shows active ingredient by common name. Diluent: Any liquid or solid material used to dilute or carry an active ingredient. Ear tag: Metal or plastic device attached to an animal's ear for identification or to control flies. Feedlot: The confined area where animals are fed. For purposes of this survey, lambs or sheep on feed are defined as those animals being fed a high energy diet for the purpose of reaching acceptable weight to be sold directly to slaughter. Lambing shed: A structure used for lambing. Lean-to: A shelter with a single-pitch roof that is attached to the side of a building as a wing or an extension. Pesticides: As defined by the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), 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. Repellent: A pesticide used to keep target pests away from a treated area by saturating the area with an odor that is disagreeable to the pest. Synergist: A material which exhibits synergism; that is, the joint action of different agents results in an effect greater than the sum of their separate effects. Trade name: A trademark name given to a specific formulation of a pesticide product. A formulation contains a specific concentration of the active 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. Trade Name, Active Ingredient, and Pesticide Class The following is a list of the associated class, (I=insecticide) and active ingredients included in this report. Also provided are product trade names associated with the listed active ingredients reported in the survey. This list is provided as an aid in reviewing pesticide data. The list is not complete for all trade names used and NASS does not mean to imply the use of any specific trade name.
