Field studies were conducted to evaluate mesotrione applied postemergence for weed control in corn.

The history and present situation of herbicide were summarized, then sulcotrione and mesotrione which were cyclohexanedione-type herbicides were summarized about their synthetic routes,physical and chemical property,action mechanics and toxicity etc with more than ninety references.

Greenhouse pot experiments were conducted to evaluate the joint effect of nicosulfuron + mesotrione and nicosulfuron + cyanazine against Amaranthus retroflexus L.

Based on studies on wetting and dispersing agents, thickening agents, and formulation optimization, a 15% mesotrione SC with superior performance, high quality and high suspension rate was achieved.

A method for the determination of mesotrione TC by HPLC with methanol and phosphate acid as mobile phase,ZORBAX EXTEND C18 column and DAD detector at 270 nm was introduced.
