The invention provides a wheat field multi-element compound herbicide composition and a preparation method thereof, the wheat field multi-element compound herbicide composition is prepared by compounding tribenuron-methyl, iodosulfuron-methyl
sodium salt, florasulam and mefenpyr-diethyl to prepare
water dispersible granules, the
control effect is good, the physical and chemical properties are stable, the wheat field multi-element compound herbicide composition is not easy to decompose and deteriorate, and the wheat field multi-element compound herbicide composition has a broad application prospect. The suspension rate reaches 96% or above; in the use process, the
water dispersible granule only needs to be dispersed once, the use process is simple, and the
water dispersible granule is a granular
solid, is good in flowability, does not stick to the wall after being poured, and does not remain in a packaging container to form secondary
pollution.
