Abstract:
The kinetics of Azinphosmethyl losses in sterile and nonsterile soil as affected by temperature and moisture content was studied. The fate of Azinphosmethyl in soil involved two steps: one after application when the initial concentration remained constant and the second when the dis-appearance starts and the Azinphosmethyl losses follow first-order kinetics. It was found that the "lag period" before Azinphosmethyl losses begin is more than a biological effect. The water and temperature affect both the lag period and the rate of disappearance.
