Neutral Hydrolysis Studies. Investigations of neutral (pH-independent) hydrolysis kinetics in sediment/water systems were conducted for three organophosphorothioate insecticides (chlorpyrifos, diazinon and Ronnel), 4-(p-chlorophenoxy)butyl bromide, benzyl chloride, and hexachlorocyclopentadiene.

Aryl-acylamidase inhibitors. Rice is resistant to the herbicide propanil due to a rice specific aryl-acylamidase which degrades the herbicide. Various carbamate and organophosphorothioate insecticides were found to be incompatible with propanil because they prevented propanil degradation. This was found to be due to a direct inhibition of this enzyme (47, 48). Such insecticides or their derivatives can be " rational" synergists when this enzyme is found to be active in degrading herbicides in weeds, and must be suppressed.
