Agricultural pesticides, formulations wettable powder

Agricultural (Ag) formulations that are commonly diluted and applied by means of spray equipment include water soluble liquids, emulsifiable concentrates, wettable powders, and flowable suspensions. The choice of which formulation to develop normally depends upon the solubility properties of the technical pesticide. Scientists often must also consider manufacturing costs, field efficacy and product toxicity. 

After the 1980s, y-HCH was used to produce lindane and other HCHs were mainly used as intermediates of HCB. There was no direct use of a- and (S-IICI after the 1980s. Lindane was used for locust and wheat midge control. Three kinds of lindane formulation were registered in the pesticide registration information system of the Chinese Ministry of Agriculture for wheat midge and locust control 1.5% powder, 6% powder, and 6% wettability powder. 

Alkylnaphthalenesulfonates Mainly butyl- and isopropylnaphthalenesulfonates, for use as wetting agents for powders (agricultural wettables, powdered pesticides). Also used as wetting agents in paint formulations. 

The ALKAMULS AG surfactants are proprietary blends developed for use in agricultural applications. The ALKAMULS AG series is appropriate for use in herbicide, pesticide and fungicide formulations, and is suitable for the development of both concentrates and wettable powders. Residues of these surfactants are exempt from tolerance requirements under EPA Regulation 40 CFR 180 1001(d) when used in accordance with good agricultural practice as inert ingredients in formulations developed for growing crops.
