Problems solved by technology

Temperature has no effect on the final effect of weeding, but affects the speed of its efficacy
Generally, when the temperature is low, the drug effect is slow, and the plant will stop growing after poisoning, but it will not die immediately; the plant will die soon after the temperature rises.

Embodiment 1

[0030] Example 1 32.5% acesulfame-clodinafop-propargyl-fluroxypyr wettable powder

[0031] 12.5% ​​of acesulfame, 10% of clodinafop-propargyl, 10% of fluroxypyr, 2% of sodium lignosulfonate, 1% of sodium dodecylbenzenesulfonate, and 100% of kaolin were added to obtain 32.5 % acesulfame-clodinafop-propargyl-fluroxypyr wettable powder.

[0032] Mix acesulfame, clodinafop-propargyl, fluroxyfen, dispersant (sodium lignosulfonate), wetting agent (sodium dodecylbenzenesulfonate), filler (kaolin), and mix in a mixing tank Evenly, it can be made into wettable powder after pulverized by jet mill and then mixed evenly.

Embodiment 2

[0033] Example 2 64% acesulfame-clodinafop-propargyl-fluroxypyr water-dispersible granules

[0034]Acesulfame 40%, clodinafop-propargyl 8%, fluroxyfen 16%, fatty alcohol polyoxyethylene ether 5%, saponin powder 4%, ammonium sulfate 2%, diatomaceous earth added to 100%, A 64% acesulfame-clodinafop-propargyl-fluroxyfen water-dispersible granule was prepared.

[0035] Acesulfame, clodinafop-propargyl, fluroxyfen, dispersant (fatty alcohol polyoxyethylene ether), wetting agent (saponica powder), disintegrant (ammonium sulfate), filler (diatomaceous earth ) and so on to obtain the required particle size through jet 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.

Embodiment 3

[0036] Example 3 60% acesulfame-clodinafop-propargyl-fluroxypyr suspension concentrate

[0037] Acesulfame 30%, clodinafop-propargyl 6%, fluroxypyr 24%, sodium lignosulfonate 5%, aluminum magnesium silicate 1%, C 10～20 Saturated fatty acids 0.3%, polyethylene glycol 2.5%, water added to 100%, prepared 60% acesulfame-clodinafop-propargyl-fluroxyacetic acid suspension concentrate.

[0038] Dispersant (sodium lignosulfonate), thickener (magnesium aluminum silicate), defoamer (C 10～20 Saturated fatty acids), antifreeze agent (polyethylene glycol) after high-speed shearing and mixing evenly, add pyresullam, clodinafop-propargyl, and fluroxyfen, and ball mill in a ball mill for 2 to 3 hours to make the particle size completely Below 5 μm, a suspension product is produced.

Abstract

The invention belongs to the technical field of pesticides, and discloses a weeding composition containing pyroxsulam, chodinafop-propargyl and fluroxypyr. According to the weeding composition, the pyroxsulam, chodinafop-propargyl and fluroxypyr are taken as main active ingredients according to the mass ratio of (1-80):(1-40):(1-60). The invention further discloses applications of the weeding composition in preparation of a pesticide for removing gramineae weeds and broadleaf weeds in an oilseed rape field. According to the weeding composition, the pesticide cost can be lowered by mixing of a weedicide, the weeding spectrum can be extended, the weeding effect is improved, the weeding composition has the advantages of being fast to take effect, long in lasting period, difficult in resistance generation, thorough to weed, low in residues, low-toxicity, safe and environment-friendly and the like, thus being a high-quality oilseed rape field weedicide, and being safe to oilseed rape.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to a herbicidal composition, in particular to a herbicidal composition containing pyresullam, clodinafop-propargyl and fluroxyfen and an application thereof. Background technique [0002] Chemical weeding is one of the main means of controlling weeds in agriculture. In recent years, due to the large-scale use of some herbicide varieties alone, many weeds have developed resistance. At the same time, because weeds occur with complex grass phases and various types, the use of a single species can no longer effectively solve farmland weeds, and all will show a certain aspect of defects. At present, there are many kinds of herbicides on the market, and at the same time, the application technology is also demanding. If there is a little carelessness in the application, problems such as phytotoxicity and poor weeding effect will occur. Improper selection of herbicides will directly affec...
