一种新型百草枯专用增效助剂的研制

[目的]研制一种新型百草枯专用增效助剂.[方法]以SHZ16表面活性剂、烷基多糖苷（APG）为原料,配制一种新型复配阳离子型表面活性剂,并采用该助剂配制成200 g/L百草枯制剂;以200 g/L克无踪水剂为对照药剂,通过小区试验设计研究了该制剂对夏玉米田1年生杂草的防除效果.[结果]采用该助剂配制的200 g/L百草枯制剂对夏玉米田1年生杂草（单、双子叶）具有较好的防除效果,药后15 d的防除效果仍在90％以上,并对夏玉米作物安全.[结论]采用该助剂配制的200 g/L百草枯制剂具有高效、安全防除玉米田杂草的生产应用价值.

Preparation of a New Special Synergy Additive for Paraquat

[Objective] The aim was to prepare a new special synergy additive for Paraquat.[Method] SHZ16 and APG were taken as materials,and a new special synergy additive for 200 g/L Paraquat formulation was prepared.Control effect of the formulation against annual weeds in maize field was studied through plot experiment.[Result] The 200 g/L Paraquat formulation had good control effect against annual weeds in maize field,and the control effect was over 90％ in 15 days after treatment,furthermore it was safe for maize.[Conclusion] The 200 g/L Paraquat formulation prepared by the new special synergy additive has production and application value in effectively and safely controlling weeds in maize field.
