Abstract

PURPOSE: To prepare a herbicide having high stability at high temperature and low temperature, storable for a long period, and having improved herbicidal activity, by compounding a quaternary bipyridylium salt with a spreader consisting of a specific nonionic surface active agent and a soecific cationic surface active agent which are soluble uniformly in the salt.
CONSTITUTION: The herbicidal activity of a quaternary bipyridylium salt can be improved by compounding 100pts.wt. of a quaternary bipyridylium salt such as 1,1- dimethl-4,4'-bipyridylium di(methylsulfate), etc. with 1W30pts.wt. of a spreader consisting of a mixture of a nonionic surface active agent of formula I (R is 6W22C alkyl, alkenyl, etc.) and a cationic surface active agent of formula II (R2 is 8W22C alkyl or alkenyl; R3 is 1W3C alkyl; l+m is 2W20; X is anion). The herbicide is harmless to crops and effective to weeds such as large crab-grass having adverse effect to the growth of crops. It has low toxicity and high safety.
