Degradation of two acetanilide herbicides in a tropical soil

The acetanilide herbicides alachlor and metolachlor are registered for control of most annual grasses and certain broadleaf weeds in many crops. In Malaysia, these two herbicides are used for weed control in corn and peanut. While much is known about their activity and mode of action, little quantit...

Description
Summary:The acetanilide herbicides alachlor and metolachlor are registered for control of most annual grasses and certain broadleaf weeds in many crops. In Malaysia, these two herbicides are used for weed control in corn and peanut. While much is known about their activity and mode of action, little quantitative information is available concerning their mode of dissipation from soils under Malaysian conditions. The primary factors affecting soil degradation of acetanilide herbicides are adsorption and microbial decomposition, with 90% of the loss attributable to the latter. Therefore, experiments were conducted to determine the degradation of alachlor and metolachlor in the soil at various moisture levels and in a field to be planted with corn and peanut.
