Embodiment 1

[0049] Weigh 20% benzotrione, 2% clodinafop-propargyl, 5% Nongru 600#, 4% Span-60#, 3% methanol, 2% epichlorohydrin, and add xylene to 100% by weight. The above-mentioned raw materials were mixed, stirred and dissolved completely to obtain 22% clodinone-clodinafop-propargyl EC.

Embodiment 2

[0051] Weigh 14% benzotrione, 2% clodinafop-propargyl, 5% Nongru 700#, 6% Nongru 600#, 3% cyclohexanone, 2% acetic anhydride, and add toluene to 100% by weight. The above raw materials were mixed, stirred and dissolved completely to obtain 16% clodinone-clodinafop-propargyl EC.

preparation Embodiment 3

[0053] Weigh 27% trimethylbenzotrione, 3% clodinafop-propargyl, 6% sodium alkyl polyoxyethylene ether sulfonate, 2% sodium alkylnaphthalene sulfonate, 0.4% magnesium aluminum silicate, 0.3% bentonite, 4% sorrel Alcohol, 0.3% sodium benzoate, 1.2% butanol, and deionized water are added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sand-milled with a sand mill until the particle size D90 was less than 10 μm to prepare a 30% clodinone-clodinafop-propargyl suspension concentrate.

Abstract

The invention discloses a weeding composition with tralkoxydim and clodinafop-propargyl and application of the weeding composition. The weeding composition comprises the tralkoxydim, the clodinafop-propargyl and auxiliaries. The tralkoxydim is a first active ingredient, the clodinafop-propargyl is a second active ingredient, and a weight ratio of the first active ingredient to the second active ingredient is 2:1-40:1. The weeding composition can be prepared to obtain agriculturally permissible missible oil, suspension agents, micro-emulsion, water emulsion, aqueous solution, dispersible oil suspension agents, wettable powder and water dispersible granules. The weeding composition and the application have the advantages that the weeding composition contains reasonable components and is low in medication cost, and good weeding effects can be realized by the weeding composition; the activity and the weeding effects of the weeding composition are not simple superposition of the activity of the various components, obvious synergistic effects further can be realized by the weeding composition besides the obvious weeding effects as compared with existing single preparations, the resistance can be delayed, the weeding composition is good in safety, and safety requirements on pesticide preparations can be met; gramineous weeds such as avena fatua, alopecurus aequalis, lolium multiflorum, sclerochloa dura, chlorsulflon, polypogon fugax and poa annua can be prevented and killed off by the aid of the weeding composition.

Description

technical field [0001] The invention relates to a herbicidal composition for wheat fields, which is composed of active ingredients trimethylphenazone, clodinafop-propargyl and auxiliary agents, and belongs to the technical field of compound pesticides. Background technique [0002] Trimethyl benzotrione, also known as salmazone, English name tralkoxydim, chemical name: 2-(1-(ethoxyimino)propyl)-5-(2,4,6-trimethylphenyl)-2 -propionyl-3-hydroxy-2-cyclohexen-1-one. It is a new type of cyclohexenone-type post-emergence selective gramineous weed herbicide developed by Zenecon, which belongs to the inhibitor of acetyl-CoA carboxylase. Tissues, inhibit the biosynthesis of fatty acids, destroy cell division, the affected weeds will lose chlorosis first, then change color and die, and generally die completely within 3-4 weeks after application. It is mainly used to control wild oats, brome and oats in wheat and barley fields , hard grass, bluegrass, clubhead grass, multiflora ryegr...
