Embodiment 1

[0023] Example 1 56% fluroxypyr-fluroxylam-flumetrazone wettable powder

[0024] Fluroxypyr 40%, florasulam 1%, mefentrazone 15%, sodium lignosulfonate 10%, sodium dodecylbenzenesulfonate 8%, kaolin to 100%, according to the above formula Weigh each component, add diclofenac, florasulam, and mefentrazone together into the cone mixer and mix evenly, then add the dispersant (sodium lignosulfonate), wetting agent ( Sodium dodecylbenzenesulfonate), filler (kaolin) are added in the conical mixer and mixed uniformly, and the uniformly mixed material is added to the jet mill for pulverization, and then mixed uniformly, sieved, and the fineness reaches 98%. 325-mesh standard sieve to obtain 56% fluroxypyr-flumezone-flumetrazone wettable powder product. After testing, the suspension rate of fluroxypyr in the 56% compound wettable powder was 91%, the suspension rate of florasulam was 92%, and the suspension rate of mefentrazone was 92%; the wettability was less than or equal to 80 seco...

Embodiment 2

[0025] Example 2 86% fluroxypyr-fluroxylam-flumetrazone wettable powder

[0026] Fluroxypyr 40%, florasulam 1%, mefentrazone 45%, sodium lignosulfonate 4%, dispersant NNO 1%, sodium dodecylbenzenesulfonate 4%, light carbonic acid Calcium was added to 100%, and the preparation method was the same as that in Example 1 to obtain 86% fluroxyfen-flumefenacil-mefentrazone wettable powder.

[0027] After testing, the 86% ternary compound wettable powder has a suspension rate of fluroxypyr: 91%, a suspension rate of florasulam: 93%, and a suspension rate of mefentrazone: 90%; the wettability is ≤ 80 seconds.

Embodiment 3

[0028] Example 3 71% fluroxypyr-flumezone-flumetrazone wettable powder

[0029] Fluroxypyr 40%, florasulam 1%, mefentrazone 30%, nonylphenol polyoxyethylene ether 2%, dispersant NNO 2%, sodium lignosulfonate 5%, dodecane Sodium phenyl sulfonate 6%, bentonite was added to 100%, the preparation method was the same as in Example 1, and a 71% fluroxypyr-flumezone-mefentrazone wettable powder was obtained.

[0030] After testing, the 71% ternary compound wettable powder has a suspension rate of fluroxypyr: 94%, a suspension rate of florasulam: 91%, and a suspension rate of mefentrazone: 95%; the wettability is ≤ 80 seconds.

Abstract

The invention belongs to the technical field of pesticides and discloses a wettable powder containing fluroxypyr, florasulam and carfentrazone-ethyl. The compounded wettable powder is prepared with the fluroxypyr, the florasulam and the carfentrazone-ethyl as main active components according to the mass ratio of 0.1-60:0.1-40:0.1-80. The total mass percentage content of the fluroxypyr, the florasulam and the carfentrazone-ethyl in the wettable powder is 1-90%. The aqueous agent also includes 1-20% of a dispersing agent, 1-10% of a wetting agent, 0-10% of a speader, 0-15% of a permeating agent and the balanced being filling materials. The wettable powder is safe and convenient to store and transport. By means of combination of the herbicides, the wettable powder is enlarged in weeding spectrum and is improved in weeding effect. The wettable powder is wide in the weeding spectrum, is quick in effects, is long in lasting period, can delay the drug resistance, is complete in weeding, is low in residue, is low in toxicity and is safe and environmental-protective. The wettable powder is an excellent chemical herbicide.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to a herbicide, in particular to a wettable powder containing fluroxyfen, florasulam and mefentrazone 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 affect the safety or yield of peo...
