Research Project: Field Testing of Minor Use Pesticides **Location:
                            Temperate Tree Fruit and Vegetable Research** 2022 Annual Report **Objectives**
                                

Provide efficacy, phytotoxicity and yield data and residue samples for analyses to support the registration or re-registration of minor use pesticides for the control or modification of behavior of pests through Interregional Project No. 4. [NP304, C3, PS 3B] **Approach**
                                

Determine needs for minor use pesticides by consulting producers, processors,
fieldmen, or their associations. Select pesticides for testing based on needs,
efficacy, economics, and safety to the crop and its environment. Conduct studies on candidate pesticides in the field, nursery or greenhouse to obtain efficacy,
phytotoxicity and yield data, and residue samples for analyses in accordance with
protocols, standard operating procedures, and good laboratory practices. **Progress Report**
                                

The Interregional Research Project Number 4 (IR-4) is the primary entity in the United States to facilitate registrations of conventional pesticides and bio pesticides on specialty food crops and non-food ornamental horticulture crops. In support of the IR-4 Project mission, residue and pest control efficacy of candidate pesticides were tested on six food crops and 14 ornamentals. It was found that levels of residues on food crops of most of the pesticides tested were below the levels established by Environmental Protection Agency (EPA) and these products were safe to use on minor crops. This information will be submitted to EPA by IR-4 Project to enable registrations of needed pesticides for use on minor food crops and ornamentals. **Accomplishments**
