The overall goal of this project was to use IPM to minimize the deleterious effects of pesticides on users, consumers and the environment while keeping crop losses below economic injury levels.
1. To continue training of CARDI/MINAG scientists in the taxonomy of broad mite predators 2. To validate a risk management model for reducing TEV (and PVY) in hot pepper 3. To test abamectin and diafenthiuron, which gave good results in Year 9 and other biorationals and low environmental impact acaricides for effects on natural enemies and predators 4. To continue studies on the relative incidence of broad mite and and its predators in sprayed and unsprayed fields and during wet and dry weather 5. To develop ratings of broad mite damage that could be used by farmers to initiate control measures 6. To develop a multi-pest integrated pest management system for hot peppers
Through this project an increased number of options will be made available to farmers cultivating hot peppers in Jamaica despite high virus pressure. This will ultimately lead to an improvement in the quality of hot peppers produced. For TEV the farmer can use the risk analysis process to determine the best time and way to plant to minimize the chance of early infection of peppers and increaseprofits at minimal management costs
