Problems solved by technology

[0002] Quizalofyl, alias R-sugarate, quinatoconate, glycoside, the chemical name is (RS)-2-[4-(6-chloroquinoxaline-2-oxyl)phenoxy]propane Acid-2-tetrahydrofuryl methyl ester is an excellent sharp-leaved weed herbicide, which can be used to control most grass weeds in broad-leaved crops. There is no domestic patent mentioning its use in soybean fields , so its mixing effect with other compounds is unpredictable

Embodiment 1

[0013] Example 1: 20% quizofofuryl · acifluorfen suspension concentrate.

[0014] Weigh 2% quizalofurate, 18% acifluorfen, 1% alkylphenol ethoxylate, 1% polystyrene phenol ethoxylate, 2% polycarboxylate, 4% ethylene glycol , 1% white carbon black, 0.4% magnesium aluminum silicate, 0.1% xanthan gum, 0.3% isooctyl alcohol, add water to make up to 100%. The above formula is pre-mixed according to the proportion, then added to a sand mill for grinding, and prepared after high-shear mixing to prepare a 20% quizofofrfur-acifluorfen suspension concentrate.

Embodiment 2

[0015] Example 2: 24% quizofofuryl · acifluorfen water dispersible granules.

[0016] Weigh 4% quizofofuryl, 20% acifluorfen, 4% sodium lauryl sulfate, 2% polycarboxylates, 5% naphthalenesulfonic acid condensate salt, 10% urea, 0.5% carboxylate Methylcellulose, add starch to make up to 100%. The above formulations were mixed in proportion, granulated, dried, and sieved to obtain 24% quizofofuryl·acifluorfen water-dispersible granules.

Embodiment 3

[0017] Example 3: 45% quizofofuryl · acifluorfen wettable powder.

[0018] Weigh 3% quizofofuryl, 42% acifluorfen, 2% sodium lauryl sulfate, 3% naphthalenesulfonic acid condensate salt, 4% lignosulfonate calcium salt, 5% white carbon black plus Kaolin to 100%. After the above raw materials were mixed, 45% quizofofuryl·acifluorfen wettable powder was obtained by jet milling.

Abstract

The invention relates to a herbicidal composition with synergy. The herbicidal composition has active ingredients of quizalofop-p-tefuryl and acifluorofen sodium in a mass part ratio of 1:1-1:5. The herbicidal composition has an excellent effect of preventing and killing weeds in soybean fields, and is safe for soybeans.

Description

technical field [0001] The invention relates to a herbicidal composition, the active ingredients of which are composed of quizofofuryl and acifluorfen. Background technique [0002] Quizalofyl, alias R-sugarate, quinatoconate, glycoside, the chemical name is (RS)-2-[4-(6-chloroquinoxaline-2-oxyl)phenoxy]propane Acid-2-tetrahydrofuryl methyl ester is an excellent sharp-leaved weed herbicide, which can be used to control most grass weeds in broad-leaved crops. There is no domestic patent mentioning its use in soybean fields , so its mixed effect with other compounds is unpredictable. [0003] Acifluorfen is a contact-type selective post-emergence herbicide, which can be absorbed by the stems and leaves of weeds, but not absorbed by roots in the soil, and is easily decomposed by microorganisms, so it cannot be used for soil treatment and is safe for soybeans. Mainly used to control broadleaf weeds. [0004] Mixing of different pesticide varieties is a common method to contro...
