Observations on Potential Uptake of Sevin by Pacific Oysters

Goal(s)/Objective(s): Gather more information on the presence of Sevin in oyster meats at varying times after treatment with different concentrations of the insecticide.

Key Findings: Sevin at a rate of 10 lb./acre or its hydrolytic product were not present in detectable quantities in Pacific oysters collected directly from the sprayed area or adjacent plantings in as short a time as 5 days after application
