Non Technical Summary
The economic incentives for pesticide manufacturers precluded their investment to the costly process of registering use of pesticides on minor crops. One of the registration requirements is to establish a tolerance (the legal limit for a pesticide residue in or on a crop at the time of harvest). The purpose of this project is to obtain pesticide residue data to support regulatory clearances for use of pesticides in the production of minor crops by conducting chemical analyses.

Goals / Objectives
To obtain chemical residue data to support regulatory clearances for use of pesticides in the production of minor crops by conducting chemical analyses according to the Good Laboratory Practices.

Project Methods
The chemical analysis processes include analytical method validation, sample receiving, sample preparation and pretreatment, sample extraction, cleanup and fractionation, sample analysis, data collection and calculation, report, sample storage study, and quality assurance. All the work is done according to the good laboratory practices well established in the laboratory. All data are calculated and organized into a report according to the good laboratory practices, submitted to the quality assurance unit. A quality assurance officer audits raw data and reports and notices laboratory analysts the QA findings and recommendations. The analysts address the QA findings and recommendations, and send the report, replies and documentation of corrective actions to the quality assurance unit again. The quality assurance officer then sends the final report, the QA report and all the documentation of the project to the IR-4 headquarters at Rutgers. The IR-4 headquarters, in turn, sends the report to the U.S. EPA for clearance review and approval for use of the pesticide on the crop studied.

Progress 10/01/00 to 09/30/04

Outputs
We have completed 23 project reports of residues of eight pesticides in 15 different minor crops. The pesticides are mefenoxam, imidacloprid, abamectin, MCPA, spinosad, dimethomorph, propiconazole, and clofentezine. The crops are papaya, kiwi fruit, cranberry, coffee, banana, pomegranate, pineapple, pea, avocado, taro, nectarine, mint peach, plum, persimmon, and grape. The reports have been submitted, via the Western Region IR-4 Office and IR-4 Headquarters, to the U.S. EPA to apply for registration of these pesticides for uses on the minor crops. There have been a total of 100 trials of residue studies completed in these 23 projects from 2000 to 2004. In addition to the 20 project reports previously documented, three new project reports submitted in 2004 are listed below. The data are necessary for registration or re-registration consideration of these pesticides for uses on the studied crops in Hawaii and the other states in the U.S.

Impacts
The pesticides residue data obtained are essential to support registration or re-registration for uses of eight pesticides in 15 different minor crops. The data are also useful information for farmers, rangers and pesticide applicators as well as for pesticide labeling.

Progress 10/01/02 to 09/30/03

Outputs
During this report period, we completed 15 project trials for residues of two pesticides on banana, coffee, pineapple and pomegranate, and submitted the reports to IR-4 Headquarters at Rutgers University via the Western Region IR-4 Office. The IR-4 Headquarters, in turn, submitted the reports to the U.S. EPA to apply for registration of pesticide for use. These studies dealt with residues of imidacloprid in coffee (2 trials), banana (2 trials) and pomegranate (3 trials), and abamectin in pineapple (8 trials). The data are necessary for registration consideration of the two pesticides on the studied crops. Residue analyses of imidacloprid in caneberry have been completed and the report is in preparation. Residue analyses of mefenoxam in papaya and spinosad in almonds are in progress.

Impacts
Residue data were obtained to support registration for use of imidacloprid on coffee, banana and pomegranate, and abamectin in pineapple. Imidacloprid is a new, systematic and effective insecticide to control sucking insects. Abamectin is also a fairly new insecticide.

Progress 10/01/01 to 09/30/02

Outputs
During this report period, we completed 29 project trials for residues of four pesticides on pea, avocado, banana, taro or nectarine, and submitted the reports to the Western Region IR-4 Office which in turn submitted them to IR-4 Headquarters at Rutgers University. Finally, the IR-4 Headquarters submitted the reports to the U.S. EPA to apply for registration of pesticide for use. These studies dealt with residues of MCPA in pea (5 trials), imidacloprid in avocado (5 trials) and banana (5 trials), spinosad in banana (3 trials) and nectarine (8 trials), and dimethomorph in taro (3 trials). The data are necessary for registration consideration of these pesticides on the studied crops. Residue analyses of mefenoxam in papaya are in progress.

Impacts
Residue data were obtained to support registration of MCPA in pea, imidacloprid in avocado and banana, spinosad in banana and nectarine, and dimethomorph in taro.

Progress 10/01/00 to 09/30/01

Outputs
During this reporting period, we completed 12 project trials for residues of three pesticides on coffee, mint or pineapple, and submitted the reports to the Western Region IR-4 Office which in turn submitted them to IR-4 Headquarters at Rutgers University. Finally, the IR-4 Headquarters submitted the reports to the U.S. EPA to apply for registration of pesticide for use. These studies dealt with residues of three pesticides which were propiconazole in pineapple (4 trials), imidacloprid in coffee (5 trials), and spinosad in mint (3 trials). The data are necessary for registration consideration of these pesticides on the studied crops. Residue analyses of dimethomorph in taro, imidacloprid in avocado, MCPA in pea, and spinosad in nectarine are in progress.

Impacts
Residue data were obtained to support registration of propiconazole, imidacloprid and spinosad for use on pineapple, coffee and mint, respectively.
