To prepare for the application of various pesticides — herbicides, fungicides, or insecticides — this spring, this would be a good time to review USDA requirements for pesticide recordkeeping. Although the recordkeeping requirements apply only to restricted use pesticides, it is a good idea to keep quality records for all pesticide applications.

The Food, Agriculture, Conservation and Trade (FACT) Act of 1990, commonly called the 1990 Farm Bill, states that private applicators must record the use of any restricted use pesticides (RUP) they apply. Under the act, RUP application records must be maintained for two years from the date of application. The certified pesticide applicator should retain these RUP records, and must be able to make them accessible for copying by authorized regulatory and medical representatives.

There is no set method for recording the use of RUPs. Applicators can develop their own method. But there are requirements as to what must be recorded. For each field application the records must include:

  • Brand/product name

  • EPA registration number (EPA Reg. No.)

  • Total amount applied

  • Crop/commodity/site/stored product

  • Field location

  • Area treated

  • Application date

  • Name of certified applicator and certification number (Cert. No.)

Greenhouse and nursery applicators also must keep all the data elements shown above. When applying spot treatments with total area of less than one-tenth of an acre, the private applicator must record the following information: Brand/product name; EPA registration number; Total amount applied; Location must be designated "spot treatment;" and Application date.

The following is a more detailed look at what is required for each of the record terms.

* Record No.: Each application must be recorded individually, e.g., Record 1 - a preplant herbicide; Record 2 - an at-planting corn rootworm insecticide; Record 3 - a foliar fungicide, etc.

* Application date: Must include month, day, and year.

* Brand/Product: Is found on the front panel of the label, e.g., Ambush Insecticide, Atrazine 4L.

* Amount: This is the "total amount," or quantity of the formulated product used. It does not include the water or other carrying agent. For example, 3 qts; 2.5 gal.; 150 lb. (for a G or WP formulation product).

* EPA Reg. No.: This is usually located in the lower part of the front label panel. It is a hyphenated set of numbers, e.g., 1234-56. Occasionally, there is a second hyphen.

NOTE: Do not record the EPA Est. No.

* Location: This is the location of the application. It can be recorded as: 1) county, range, township, and section; 2) a system using maps and/or written descriptions; 3) the field numbers designation used by USDA agencies; or 4) the legal property description.

* Area Treated: This is the total area treated and should be in terms of the label directions, e.g., acres, linear feet, square feet, etc. For livestock and poultry, enter the number of animals treated.

* Crop/commodity/site/stored product: Use general terms, e.g., wheat, corn, alfalfa, (do not use scientific or variety names). Commodity includes stored products such as grain or apples. Site is entered as livestock, fence rows, poultry, etc.

* Applicator's name: This is the name of the certified private applicator who made or supervised the application. It would be good to note the name of the applicator if it was not the certified applicator.

* Cert. No.: This is the private applicator’s certification number (issued by the Kansas Department of Agriculture, or by a reciprocal state).

Other valuable, but not required, information could include:

* What the target pest(s) were — greenbugs, pigweeds, corn borer, etc.

* Size/density of target pest — e.g., 100 (greenbugs or weeds) per row or square foot,

larvae/adults (insects), seedling (weeds), etc.

* Adjuvants, drift agents, and other additives used to enhance the application effectiveness.

* Environmental conditions — Record as actual data or estimates. Wind speed should be recorded in miles per hour, not generalities such as calm, light etc.

* Method of application — Examples are air, ground, chemigation, incorporation, etc.

* Equipment used — This can be general, such as boom, band, aircraft; or specific equipment can be listed.

* Reentry time/date (t/d) — For worker protection standards information.

* Comments — This can relate to any aspect that may be helpful in the future. For example: 3 days of cool temps (or other factors) occurred after application, which may reduce the pesticide’s level of control.
