Embodiment 1、39

[0025] (embodiment 1, 39% emulsifiable concentrate)

[0026] 39% Mefenoxazone · Pretilachlor EC: 1% Mefenoxazone, 38% Pretilachlor, 12% Promethazine, Emulsifier Di-Seconyl Maleate Sulfonate Sodium 5%, Emulsifier 3% phenylethylphenol polyoxyethylene ether, sec-butyl acetate 15%, solvent naphtha 150# make up to 100% (above contents are mass percentages, the same below).

[0027] 39% fenoxazone-butachlor EC: 1% fensulfentrazone, 38% butachlor, 12% fenzachlor, 5% emulsifier di-octyl maleate sulfonate sodium, Emulsifier 3% phenylethylphenol polyoxyethylene ether, 15% sec-butyl acetate, 150# mineral spirits make up to 100%.

[0028] The preparation method is as follows: put all the weighed materials into the batching kettle, stir and dissolve until completely transparent to obtain emulsifiable concentrate, and transfer to the storage tank for filling after passing the test.

Abstract

The invention discloses a herbicidal composition containing carfentrazone, the active ingredients of which are carfentrazone and pretilachlor, or carfentrazone and butachlor. The herbicidal composition of the present invention can effectively control various annual and perennial weeds at one time, has high selectivity to rice and barnyardgrass, and is difficult to remove barnyardgrass, daughter daughter, crabgrass, and Yujiuhua in paddy fields. Weeds such as weeds, cattle felt, Cizao, and firefly have special effects. The herbicidal composition of the present invention has a good synergistic effect, the application effect is obviously better than the sum of the theoretical effects of a single agent, has a super-superimposed effect, and can better control the occurrence and damage of dominant weeds; in addition, the herbicidal composition reduces the dosage of chemicals, reduces Use cost and environmental pollution, improve the safety of crops.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a herbicidal composition containing carfentrazone and its application. Background technique [0002] Rice is one of the main crops in our country. For a long time, barnyardgrass, syringa, and three-edge grass (including Japanese sedge, flat stalk, and three-edge grass, etc.) have been the three major harmful weeds in rice fields; in addition, some Due to the long-term and continuous use of pyrazosulfuron-methyl, bensulfuron-methyl and other pesticides in the area, the damage of the more serious malignant weeds Azalea and heteromorphic sedges has been gradually reduced, but the perennial wild arrowhead, Alisma and annual The hazards of Yujiuhua, duck tongue grass, wild water chestnuts, and Moshang vegetables are aggravated. There are also weeds such as Yinglin, Acupuncture, and cattle felt in the rice fields. [0003] The use of a single herbicide has a limited co...
