Embodiment 1

[0041] Weigh 5% saflufenacil, 21% glyphosate, 4% fenflumezone, 12% xylene, 7% fatty alcohol polyoxyethylene ether, 0.5% silicone oil, 1% penetrant JFC, deionized Water to make up the balance. Dissolve saflufenacil and fenflumezone in xylene, add fatty alcohol polyoxyethylene ether and stir evenly to form an oil phase, add the oil phase to deionized water in which glyphosate has been dissolved, and then add other additives, Stir evenly to make 30% saflufenacil·glyphosate·oxaflumezone aqueous solution.

Embodiment 2

[0043] Weigh 10% saflufenacil, 15% glyphosate, 10% mesotrione, 18% methanol, 6% calcium dodecylbenzenesulfonate, 0.2% hexanol, 2% azone, deionized Water to make up the balance. Dissolve saflufenacil and mesotrione in methanol, add calcium dodecylbenzenesulfonate and stir evenly to form an oil phase, add the oil phase into deionized water in which glyphosate has been dissolved, and then add other additives , Stir evenly to make 35% saflufenacil·glyphosate·mesotrione aqueous solution.

Embodiment 3

[0045] Weigh 15% saflufenacil, 25% glyphosate, 5% flumetrione, 15% n-butanol, 6% sorbitan monostearate, 0.4% octanol, 2% aureus Ketone, deionized water to make up the balance. Dissolve saflufenacil and afluorotrione in n-butanol, add sorbitan monostearate and stir evenly to form an oil phase, add the oil phase to deionized water in which glyphosate has been dissolved, and then add other Additives, stir evenly to make 45% saflufenacil glyphosate afluorotrione aqueous solution.

Abstract

The invention discloses a weeding composition containing saflufenacil and application of the weeding composition. The weeding composition is characterized in that effective active ingredients comprise a first active ingredient of saflufenacil, a second active ingredient of glyphosate and a third active ingredient of HPPD (Hydroxyphenylpyruvate dioxygenase); the weight ratio of the saflufenacil to the glyphosate to the HPPD is (0.1 to 50) : (0.1 to 50) : (0.1 to 50). The composition can be prepared into agriculturally allowable aqueous solutions, suspending agents, suspoemulsions, dispersible oil suspension agents, wettable powder, water dispersible granules, granules and microcapsule suspension-suspension agents. The composition has the advantages that the components are reasonable, the weeding effect is good, and the activity and the weeding effect are not simple superposition of the activity all components; compared with the existing single preparation or binary compound preparation, not only is the weeding effect significant, but also the significant synergistic effect is achieved, the drug dosage is reduced, the weed control spectrum is increased, and the safety to crops is good.

Description

technical field [0001] The invention relates to a herbicidal composition, which consists of active ingredients saflufenacil, glyphosate, HPPD inhibitor and auxiliary agent, and belongs to the technical field of compound pesticides. Background technique [0002] Saflufenacil, the English name is saflufenacil, the chemical name is: N'-[2-chloro-4-fluoro-5-(3-methyl-2,6-dioxo-4-(trifluoromethyl) -3,6-Dihydro-1(2H)-pyrimidine)benzoyl]-N-isopropyl-N-methylsulfamide. Saflufenacil is a uracil herbicide developed by BASF. It is a protoporphyrinogen oxidase (PPO) inhibitor that destroys cell membranes through "fat peroxidation", eventually leading to cell leakage, tissue necrosis, and plant damage. die. It can quickly eradicate and control more than 70 kinds of broadleaf weeds, including weeds resistant to glyphosate and ALS inhibitors. It is effective against small-seeded broad-leaved weeds such as amaranth and pigweed and difficult large-seeded weeds such as sunflower, velvetleu...
