Research Project: Pesticide Trials in Vegetable and Ornamental Crops to Support the Ir-4 Program

Location: Vegetable Research

2013 Annual Report


1a.Objectives (from AD-416):
To obtain efficacy and residual data of insecticides, miticides, herbicides and fungicides on vegetable crops and ornamentals against insects and mites.


1b.Approach (from AD-416):
Field evaluations of insecticides, miticides, fungicides, and herbicides will be conducted on vegetable and ornamental crops. Research will be conducted according to IR-4 protocols and good laboratory practices. No specific treatments can be mentioned ahead of time because program needs change depending on industry requests. Residue samples will be assayed by appropriate federal, state, or private laboratories.


3.Progress Report:
Field data were collected in cooperation with the IR-4 Project (formerly named Interregional Research Project #4) and cooperating crop protection industries. The IR-4 project is a national minor use pesticide program. Residue and performance trials with fungicides were completed for 13 food crop studies (9 residue trials on basil, cabbage, cantaloupe, cucumber, squash, and tomato; 4 performance trials on bell pepper, cucumber, squash and tomato). Insecticide and fungicide performance trials were also completed for 11 ornamental crop studies. Crop samples were provided to cooperators for pesticide residue analyses, and completed field data books were provided to the IR-4 Project headquarters. Established protocols were followed in the conduct of all IR-4 studies.


4.Accomplishments
1. Research supporting the registration of pesticides on vegetable and ornamental crops. Because of a need for data to support the registration of pesticides on vegetable and ornamental crops, ARS researchers developed information about the use of experimental materials at Charleston, SC, in cooperation with the IR-4 Project and various crop protection industries. Research on fungicides were completed for 13 food crop studies. Also, insecticide and fungicide performance trials were completed for 11 ornamental crop studies. Results from this work are being used to support the registration of needed pesticides on specialty crops, and the pesticides will subsequently be available for use by growers. Information from these trials and the availability of new pesticides that may result provide new and effective tools for producers of the horticultural test crops.
