Project Number: 3607-21000-009-01
Project Type: Specific C/A

Start Date: Sep 26, 2000
End Date: Aug 31, 2005

Objective:
To study the pesticide dose-transfer process in greenhouses related to application equipment, application rate, application volume, host plants and pests, to help growers select appropriate application equipment for management of different crop and pest combinations.

Approach:
Apply selected conventional and/or biorational pesticides with 12 hour or less restricted entry intervals using highand low volume sprayers to relate existing data on spray drop deposition and distribution to efficacy against major insect and mite pests of greenhouse crops. Additional deposition and distribution data will be obtained to compare with information obtained previously. Determine effects of spray application rate and spray volume on pesticide contact and residual efficacy. Use existing bioassay methods, or develop new ones, to measure systemic, contact and residual effects of products in commerical greenhouses. Evaluate effects of plant growth stage and canopy thickness on pesticide efficacy. When possible, use scanning electron microscopy and dispersive x-ray analysis to examine pesticide deposition and distribution.
