Metamitron is a kind of selective pre-emergence triazone, low residue, high efficiency and low toxicity herbicide. The medicament was absorbed by root and gradually transported to leaf, then kill the weeds through photosynthesis inhibition. With pesticide formulations to the trend of the development of the environmental protection type, the high content and environment friendly for the development and application becomes the important direction of pesticide products＇ developmentt51. The herbicide formulation type was screened according to the use requirements of medicament on soil, pharmacodynamic action principle, processing and application of influence to the environment to achieve the low toxic and high efficient pesticide formulation.Based on the physicochemical properties of metamitron, the author designed suspension concentrate （SC）. The stable performance, good effect, reliable quality, high content and high suspension rate （example： metamitron 700g / LSC） waterbased products was made through agent, antifreeze, screening a variety of high performance wetting, dispersing agent, thickening water and other additives screening, and optimizing the auxiliary combination.
