The study of cyhalofop-buthyl (CB) persistence on two different soils shows a t1/2 lower than 90 min. After few hours, CB hydrolized to cyhalofop acid (CA) which gives rise to degradation products different on the two soils. The t1/2 of CA is 42 d in the paddy-field soil and 3 h in the forest soil.

Abstract

The study of cyhalofop-buthyl (CB) persistence on two different soils shows a t1/2 lower than 90 min. After few hours, CB hydrolized to cyhalofop acid (CA) which gives rise to degradation products different on the two soils. The t1/2 of CA is 42 d in the paddy-field soil and 3 h in the forest soil. The experiments repeated on sterile soils show the main role of microorganisms in the degradation. The adsorption of CA on sterile soils is low and characterized by a certain reversibility.
