The invention relates to a
solid preparation of a novel sterilant herbicide composition employing
saflufenacil and
glyphosate and containing a herbicide auxiliary agent. The
solid preparation comprises the two effective compositions
saflufenacil and
glyphosate, the auxiliary agent and a carrier. The two effective compositions
saflufenacil and
glyphosate account for 10%-70% by weight of the composition, and the weight ratio of saflufenacil to glyphosate is 1:5-1:40. The
solid preparation of the herbicide composition containing saflufenacil and glyphosate employs a particulate agent, a
wettable powder and a water-dispersable granule as a product form. The herbicide auxiliary agent is a combination of at least two or more of a
plant-resource spray auxiliary agent, a
plant-source SD auxiliary agent, an
alkyl glycoside surfactant, a trisiloxane surfactant, a
tallow amine surfactant, betain, amino oligosaccharin and a penetrating agent JFC. The herbicide composition containing the herbicide auxiliary agent has excellent control
efficacy on common gramineae and broad leaf weeds, and especially on weeds generating
drug resistance on herbicides such as glyphosate, sulfonylureas, triazines and the like.
