Embodiment 1

[0024] Embodiment 1 is a dosage form preparation example, and embodiment 2 is a biological embodiment,

[0025] Example 1:

[0026] a: wettable powder

[0027] With 50 parts by weight of active ingredient composition and 2 parts by weight of sodium lauryl sulfate as wetting agent, 10 parts by weight of granular white carbon black as adsorbent, 5 parts by weight of wood as dispersant Sodium sulfonate and 63 parts by weight of kaolin are ultrafinely pulverized in a jet mill.

[0028] b: suspending agent

[0029] 20% active component A and 20% active component B with 10% alkylphenol polyoxyethylene ether as emulsifier, 5% ethylene glycol as antifreeze, 2% benzene as preservative Sodium formate and 1% xanthan gum as a thickener can be obtained by wet grinding in water to obtain a suspending agent.

[0030] c: EC

[0031] The emulsifiable concentrate can be obtained by fully dissolving and mixing 20% ​​of active component A and 5% of active component B with 15% of emulsifier 2...

Embodiment 2

[0034] Embodiment 2, the control effect of the mixed use of cloxazone and quizalofop-p-ethyl on soybean field weeds

[0035] Location: Jiangsu, Xinyi

[0036] Application period: 2-3 leaf stage of weeds Survey: 21 days after application Time: 2009

[0037]

[0038] Conclusion: The actual control effect of the mixed use of chlorester-sulam and quizalofop-p-ethyl is higher than the expected theoretical control effect of the mixed use, and it can expand the herbicidal spectrum. Herbicidal spectrum effect.

Abstract

The invention relates to a weeding composition containing cloransulam-methyl and quizalofop-p-ethyl as well as a preparation method and application thereof. The weeding composition is a mixture formed by a compound (A) cloransulam-methyl and a compound (B) quizalofop-p-ethyl. The weeding composition is characterized in that the proportion of the compound (A) cloransulam-methyl to the compound (B) quizalofop-p-ethyl is 1-100:1. The composition of the invention can be processed into wettable powder, emulsifiable concentrate, a suspending agent and a water dispersible granule agent and can effectively prevent and remove broadleaf weeds in the soybean field, such as goosefoots, amaranth, polygonum, siberian cocklebur, elsholtzia, piemarker, nightshade, field sowthistle flower, cephalanoplos, and the like and annual and perennial poaceae weeds, such as cockspur grass, green bristle grass, wild oat, brachiaria eruciformis, eleusine indica, bromegrass, caper euphorbia seed, knuckle grass, eragrostis pilosa, bermuda grass, reed, couch grass, and the like. The preventing efficiency of the weeding composition is obviously higher than that of the single compound (A) or the compound (B), and the applying dosage of various active substances is greatly reduced.

Description

Technical field: [0001] The present invention relates to herbicidal compositions having improved properties. Specifically, it relates to a herbicidal composition containing clofenacyl-sulam and quizalofop-p-ethyl. Background technique: [0002] The chemical name of compound (A) clofensulfame is: 3-chloro-2-(5-ethoxy-7-fluoro[1,2,4]triazol[1,5-c]pyridine-2- base) methyl sulfonylaminobenzoate. The common name in Chinese is clofensulfame. [0003] The structural formula of compound (A) is as follows: [0004] [0005] The English name of cloransulam is: cloransulam-methyl. The CA registration number is: 147150-35-4. Clossulam was developed by Dow Agricultural Sciences Company of the United States. Obtained patents CN1030606C(3), CN1037605C(2). [0006] Clossulam can control broadleaf weeds in rapeseed, soybean, potato, tobacco and transplanted cabbage fields. The main weeds controlled by Chlorester-Sulfam include broad-leaved weeds such as Chenopodium, Amaranth, Poly...
