Preparation and Properties Study of Herbicides Using Lignosulfonates as Dispersants
Lignin sulfonates have strong dispersibility,adhesion,and chelation properties,which have promising applications in industrial water treatment,leather industry,electroplating industry,and pesticide additives.In this article,lignosulfonate was prepared using hydrolyzed lignin as raw material,which was used to disperse methanesulfuron and benzenesulfuron herbicidesto prepare herbicide dispersible granules.The performance of herbicides using lignosulfonates as dispersants was studied through field efficacy experiments.The results showed that the pH values of the herbicide samples of benzenesulfuron and methanesulfuron were 6.0 and 4.5,respectively,showing weak acidity and strong acidity.Zeta potentials of these two samples were-23.5 mV and-24.5 mV,indicating good stability of the herbicide sample.The control effect of the last application of herbicide dispersible granules on plants is between 59.38%and 100.00%.
