Description

Ternary weeding composition and application thereof Technical Field The invention belongs to the field of pesticides, and particularly relates to a ternary weeding composition and application thereof. Background Chemical weeding is the most economical and effective means in farmland weed control, but long-term continuous high-dosage chemical herbicide with single variety or single action mode is easy to cause problems of weed resistance, resistance evolution and the like. The reasonable compounding or compounding of the herbicide compound has the advantages of expanding the weed spectrum, improving the preventing and killing effect, delaying the occurrence and development of weed resistance and drug resistance, and the like, and is one of the most effective methods for solving the problems. Therefore, there is a need in the art to develop herbicidal compositions that are highly safe, broad-spectrum, synergistic and resistant to weeds. Disclosure of Invention In order to solve the problems in the prior art, the invention provides a ternary weeding composition and application thereof, and the composition can effectively prevent and remove various weed problems such as gramineae weeds, broadleaf weeds and the like, and has the characteristics of expanding a weeding spectrum, reducing application amount, generating synergistic effect, solving resistant weeds and the like. A ternary herbicidal composition comprising a herbicidally effective amount of active ingredient A, active ingredient B and active ingredient C, wherein, The active component A isOr clomazone (CAS number 81777-95-9); the active component B is isoxaflutole (CAS number: 141112-29-0), fenpyraclonil (CAS number: 1992017-55-6), Or mesotrione (CAS number 104206-82-8); the active ingredient C is metribuzin (CAS number: 21087-64-9). In one embodiment, A, B and C in a weight ratio of 1-100:1-150:1-500, 5-80:3-100:5-300 10-60:5-90:10-150, 15-40:10-60:15-80 or 20-30:15-25:40-50. The mass percentage of A, B and C in the weeding composition accounts for 1-95%, preferably 10-80% of the total mass. The herbicidal composition further comprises conventional adjuvants including carriers and/or surfactants. The term "carrier" as used herein means an organic or inorganic, natural or synthetic substance.
