Mixed herbicide containing pyroxsulam, fluroxypyr and florasulam

Abstract

The invention belongs to the technical field of pesticides and discloses a mixed herbicide containing pyroxsulam, fluroxypyr and florasulam. The mixed herbicide takes pyroxsulam, fluroxypyr and florasulam as main effective components and the mass ratio of pyroxsulam to fluroxypyr to florasulam is (1-80) to (1-40) to (1-60). The mixed herbicide can be applied to prevention and removal of weeds in oilseed rape fields. According to the mixed herbicide provided by the invention, the weeding spectrum is enlarged by the mixing of the herbicide and the weeding effect is improved; and the herbicide has the advantages of rapid effect, long lasting period, delaying of herbicide drug resistance, complete weeding, low residues, low toxin, safety and environment friendliness and the like; and the herbicide is a high-quality chemical herbicide of the oilseed rape fields, is safe to oilseed rapes, and has prominent prevention and treatment effects on grassy weeds, euphorbiaceae weeds, caryophyllaceae weeds, and rubiaceae weeds, such as oat, alopecurus aequalis, barnyard grass, euphorbia helioscopia, leptochloa chinensis, galium aparine, stellaria media and malachium aquaticum.

Description

technical field

[0001] The invention belongs to the technical field of pesticides and relates to a herbicide, in particular to a mixed herbicide containing acesulfame, fluroxypyr and florasulam and an application thereof. Background technique

[0002] Pyroxsulam, chemical name: N-(5,7-dimethoxy[1,2,4]triazol[1,5-a]pyrimidin-2-yl)-2-methoxy -4-(trifluoromethyl)-3-pyridinesulfonamide. Acesulfame belongs to triazolopyrimidine sulfonamide herbicides, has systemic transduction effect, broad herbicidal spectrum, high herbicidal activity and fast drug effect. Its mechanism of action is the inhibitor of acetolactate synthase (ALS), which is absorbed by weed leaves, sheaths, stems or roots, and accumulates at the growth point, inhibiting the synthesis of acetolactate synthase, resulting in the inability to synthesize branched-chain amino acids, and then Affect protein synthesis, affect weed cell division, cause weeds to stop growing, and then die. It is mainly used to control gras...

[0033] Example 256% acesulfame-fluroxyfen-flumefenacil water dispersible granules

[0034] Acesulfame 40%, fluroxypyr 8%, florasulam 8%, fatty alcohol polyoxyethylene ether 5%, saponin powder 4%, ammonium sulfate 2%, diatomaceous earth added to 100 %, 56% of acesulfame-fluroxyfen-flumefenacil water-dispersible granules were prepared.

[0035] Acesulfame, fluroxyfen, florasulam, dispersant (fatty alcohol polyoxyethylene ether), wetting agent (saponica powder), disintegrant (ammonium sulfate), filler (silicon algae) and so on to obtain the required particle size through airflow crushing to obtain the granulation material. Quantitatively send the material into the fluidized bed granulation dryer for granulation and drying to obtain water-dispersible granules.
