REGISTRATION OF PESTICIDES FOR USE IN MINOR CROPS

Pests (e.g., insects, weeds, and diseases) can severel= y reduce growers' yields and increase the cost of production. Although cultural, physical, mechanical, and biological methods of pest control may be available, they may not individually or collectively be feasible for the grower to implement. Chemicals (i.e., pesticides) are anot= her tool growers can use to mitigate losses due to pests. However, growers cann= ot use just any pesticide; the crop on which the pesticide will be applied mus= t be listed on the pesticide product's label. And for food crops, a tolerance mu= st first be established by the Environmental Protection Agency (EPA) before a chemical company can list a crop grown for food on a pesticide product's la= bel. A tolerance is the maximum amount of pesticide residue than can remain in o= r on a crop at the time of harvest. Once the tolerance is established, the crop = can be included on the pesticide's label along with the specific directions for use. Only then can growers legally use the pesticide for use on the crop. T= he process is very costly, complex ,and time-consum= ing. It is estimated that a minimum of six years is required, if all goes well, = to successfully register a pesticide for use in a minor crop.

INTERREGIONAL RESEARCH PROJECT NO. 4 (IR-4)

IR-4 is a USDA-supported program that provides limited funding and a mechanism to register pesticides for use in minor crops. Registering a pesticide use in a minor crop involves generating efficacy, <= span class=3DSpellE>phytotoxicity, and residue data, preparing a tolerance petition, paying tolerance review fees, etc., which is a costly process. Sa= les of pesticide product from many minor crop registrations would not recover t= he costs associated with obtaining the registrations. Therefore, although the = need for a pesticide exists in minor crops, registrants (chemical companies) are reluctant to register the use if no return on t= heir investment is projected. IR-4 was established in 1963 to provide some incen= tive for registrants to register pesticides for use in minor crops.
