Research Project: In Season Insecticide Control of Navel Orangeworm, Assessment of Application Coverage, and Relative Environmental Stability of Insecticides

Location: Commodity Protection and Quality

Project Number: 2034-43000-037-09
Project Type: General Cooperative Agreement

Start Date: Sep 06, 2011
End Date: Dec 31, 2014

Objective:
The overall goal of this project is to ensure strategic application of chemicals to control navel orangeworm (NOW) in almonds by mapping the environmental fate and transport of insecticides, particularly degradative pathways involving solar photolysis.

Approach:
This research will integrate laboratory, model ecosystem, and field studies for the purpose of tracing the signature of organic agrochemicals through the environment. The specific approach involves: 1) developing methods of spectroscopic and mass spectrometric analysis of pyrethroids, 2) probing the direct and indirect sunlight-mediated photolysis of pyrethroids through a combination of kinetic modeling and byproduct analyses, 3) characterizing the chemical constituents of nut hulls as related to sun-light mediated degradation, and 4) relating sunlight-mediated degradation to the relative toxicity of pyrethroids and resulting products.
