Leaching potential of metribuzin in agricultural soils


Author(s): J. D. Saritha, T. Ram Prakash, M. Madhavi and P. C. Rao

Abstract: Metribuzin is a triazinone herbicide used as a pre and post-emergence herbicide to control annual grasses and broadleaf weeds in the field and vegetable crops. Sorption of herbicide on soil directly or indirectly controls the fate of herbicide, including movement in soil. Metribuzin adsorption is influenced by various soil physical, chemical and physico-chemical properties. Metribuzin sorption behavior is highly correlated with the organic matter, clay content and the adsorption isotherms are well described by the Freundlich equation. The present investigation reports the influence of physico-chemical parameters sorption and leaching of metribuzin. Leaching potential assessment was done by Groundwater Ubiquity Score (GUS) by using The istribution coefficients Kd, Koc for the soils . According to GUS scores S-3 soil sample resulted as non leachable with 1.8 score, S-1 is transitional with 2.22 , S-3 is leachable with 2.88 score.
