Problems solved by technology

[0004] The purpose of the present invention is to provide a soybean field herbicide composition, which can improve the drug efficacy, expand the herbicidal spectrum, solve the shortcomings of the single preparations of the two pesticides, fluorfen-carboxyfen and quizalofop-p-ethyl, and can effectively prevent and control gramineous weeds at the same time. Grass and broad-leaved weeds, to save the use of pesticides and reduce the labor waste caused by repeated spraying, and the cost is low and the pollution is small

Embodiment 1

[0011] The following recipes are calculated as percentages.

[0012] 5% quizalofop-p-ethyl, 10% oxyflufen, 5% alkylphenol polyoxyethylene ether, 10% lignosulfonate, 5% butyl glycidyl ether, 6% glycerin, and the rest is supplemented by water to 100%.

[0013] The preparation method is as follows: in a high-speed shear mixing emulsifier, add quizalofop-pyl-ethyl, ethylcarboxyfluorfen, alkylphenol polyoxyethylene ether, lignosulfonate, butyl glycidyl ether, glycerin in sequence according to the formula amount and water, through emulsification, homogenization, testing and packaging, to obtain a 12% soybean field herbicide composition.

Embodiment 2

[0015] The following recipes are calculated as percentages.

[0016] 10% quizalofop-p-ethyl, 15% oxyfluorfen, 4% alkylphenol polyoxyethylene ether, 5% lignosulfonate, 6% epoxidized soybean oil, 5% ethylene glycol, and the rest is supplemented by water to 100%.

[0017] The preparation method is as follows: in a high-speed shear mixing emulsifier, add quizalofop-pyl-ethyl, acifluorfen, alkylphenol polyoxyethylene ether, lignosulfonate, epoxidized soybean oil, ethylene glycol in sequence according to the formula amount Alcohol and water are emulsified, homogenized, tested and packaged to obtain a 10% soybean field herbicide composition.

Embodiment 3

[0019] The soybean field herbicide compositions prepared in Example 1 and Example 2 were respectively subjected to field efficacy tests with commercially available 10.8% quizalofop-p-ethyl EC and 10% aciflufen, and the test results were compared as shown in Table 1. Show:

Abstract

The present invention relates to a herbicide composition for soybean fields. The composition is an emulsion in water, including the following ingredients: 5% to 20% by weight of quizalofop-p-ethyl, 5% to 20% by weight of fluoroglycofen-ethyl, 3% to 12% by weight of an emulsifier, 3% to 12% by weight of a dispersing agent, 1% to 10% by weight of a stabilizer, 4% to 7% by weight of an antifreeze and the balance being dispersing medium water. The herbicide composition for soybean fields has improved herbicide effect and expanded herbicidal spectrum to overcome the disadvantage of single preparation of the two pesticides quizalofop-p-ethyl and fluoroglycofen-ethyl, and can effectively control grass weeds and broadleaf weeds, so the usage amount of pesticides is saved and labor waste caused by repeated pesticide spraying is reduced, and the cost is low and the pollution is little.

Description

technical field [0001] The invention relates to an agricultural herbicide, in particular to a soybean field herbicide composition. Background technique [0002] Acefluorfen is a diphenyl ether herbicide, which can control broad-leaved weeds and grass weeds in wheat, barley, peanut, soybean and rice fields. It can control a variety of annual weeds in soil treatment. Stem and leaf treatment It has a high control effect on annual broad-leaved weeds, but its control effect on gramineous weeds is poor. [0003] Quizalofop-ethyl is a highly selective new dry field stem and leaf treatment agent, which is highly selective between grass weeds and dicotyledonous crops, and has a good control effect on grass weeds in broad-leaved crop fields , the action speed is faster, the drug effect is more stable, and it is not easily affected by environmental conditions such as rain, temperature and humidity, but its control effect on broad-leaved weeds is poor.
