2012 Annual Report
1a.Objectives (from AD-416):
To evaluate the effectiveness and phytotoxicity of nematicides, fungicides, herbicides, insecticides, and acaricides on minor food crops and ornamentals in the southern U.S., and to generate samples for analysis of pesticide residues to be used in registering pesticides on minor food crops and ornamentals.
1b.Approach (from AD-416):
Field and/or greenhouse tests will be conducted under good laboratory/field procedures to determine the effects of pesticides on pests of minor food crops and ornamentals. Nematode, disease, weed, insect, and mite population densities will be monitored in treated and untreated plots and pest damage, crop response and yields will be recorded. Mature fruit and/or plant parts will be harvested, shipped to designated laboratories, and analyzed for pesticide residues. Plant species, pesticides and treatment rates are determined by IR-4 Minor Use Pesticide protocols. Data will be summarized, analyzed, and reports will be submitted to IR-4 Headquarters to support registration and reregistration of pesticides on minor food crops and ornamentals.
The Interregional Research Project No. 4 (IR-4), Crop Protection and Management Research Unit, Tifton, Georgia, conducted eleven residue food use field trials during fiscal year 2012 including eight fungicide trials, two insecticide trials, and one plant growth regulator trial. The fungicide trials (pesticide/crop) included the following: fluazinam/cucumber, fluopicolide/snap bean, penthiopyrad/blueberry, quinoxyfen/cucumber, quinoxyfen/summer squash, V10208/bell pepper, V10208/cucumber, and V10208/summer squash. The insecticide trials included the following: pyrethrins + piperonyl butoxide/mustard and spirotetramat/carrot. The plant growth regulator trial was hexazinone/blueberry.
This project also conducted five efficacy and phytotoxicity food use field trials consisting of four fungicide trials and one herbicide trial. The fungicide trials included the following: acibenzolar/bell pepper, quinoxyfen/cucumber, quinoxyfen/summer squash, and quinoxyfen/tomato. The herbicide trial was pendimethaline/blueberry.
Nine ornamental trials also were conducted during the year to provide phytotoxicity data for potted plants in field conditions including five fungicide trials and four herbicide trials. The five fungicide trials were acibenzolar on boxwood, butterfly bush, indian hawthorn, lillyturf, and juniper and the four herbicide trials were indaziflam on boxwood, holly, indian hawthorn, and lillyturf.
These trials provide residue, efficacy and phytotoxicity data for numerous pesticide and crop combinations and will be used to support registration or re-registration of reduced risk pesticides on minor use food crops. All magnitude of residue trials were conducted in compliance with the Good Laboratory Practice Standards issued by the Environmental Protection Agency under the Federal Insecticide, Fungicide and Rodenticide Act (40 CFR Part 160). Our research contributes to both the pest control technologies and chemical control of weed components of the crop protection and quarantine national program action plan. Data books will be sent to IR-4 Headquarters within two months of completion.
