Embodiment 1

[0023] Cotton field stem and leaf treatment herbicide composition: active ingredient content of 55% by weight of triflupyrsulfuron-ethoxydim (1:10) wettable powder: respectively weigh 5% trifluxysulfuron-methyl, 50% alkenyl Hexidine, 6% sodium lignosulfonate, 3% pull open powder BX, 3% azone penetrant, and white carbon black make up to 100%. The above-mentioned raw materials are mixed uniformly in a mixer, and the powder preparation with a certain particle size obtained by airflow pulverization, after passing the inspection, can obtain 55% triflupyrsulfuron-ethoxydim wettable powder.

Embodiment 2

[0025] Cotton field stem and leaf treatment herbicide composition: active ingredient weight percent content 31.5% trifluxysulfuron-sethoxydine (1:20) wettable powder: weigh 1.5% trifluxysulfuron-methyl and 30% sethoxydim respectively Pyridine, 7% polycarboxylate, 4% sodium lauryl sulfate, 3% span80, 20% white carbon black, and kaolin make up to 100%. Mix the above raw materials uniformly in a mixer and then airflow pulverize to obtain a powder preparation with a certain particle size. After passing the inspection, a 31.5% trifluxyrsulfuron-ethoxydim wettable powder can be obtained.

Embodiment 3

[0027] Cotton field stem and leaf treatment herbicide composition: active ingredient weight percent content 37.2% trifluxysulfuron-sethoxydine (1:30) wettable powder: weigh 1.2% trifluxysulfuron-methyl and 36% sethoxydim respectively Pyridine, 5% sodium lignosulfonate, 4% sodium dodecylbenzenesulfonate, 3% span80, 25% white carbon black, and kaolin make up to 100%. Mix the above raw materials uniformly in a mixer and then jet mill the powder preparation with a certain particle size. After passing the inspection, a 37.2% trifluxyrsulfuron-ethoxydim wettable powder can be obtained.

Abstract

The invention belongs to the technical field of herbicides, and specifically discloses a herbicide composition for treating cotton field stems and leaves, and also discloses its application. The herbicide composition is obtained by mixing active components and auxiliary materials, the active components are trifluxysulfuron and sethoxydim, and the weight ratio of trifluxysulfuron-methyl to sethoxydim is: trifluxysulfuron-methyl:sethoxydim Pyridine=1:(10-80). The herbicide composition for treating stems and leaves in cotton fields of the present invention has good herbicidal effect and wide herbicidal spectrum, can improve the control effect on weeds in cotton fields to a greater extent, and can control grass weeds and broad-leaved weeds that mainly occur in cotton fields. and Cyperaceae weeds all have significant control effects, and the dosage is small, which reduces the degree of impact on the environment; effectively delays the emergence and development of weed resistance and prolongs the service life of the agent; the herbicide composition is used by cotton After the plant absorbs it, it is fixed in the cotton leaves and cannot be moved, and can be quickly metabolized, so it is extremely safe for cotton.

Description

technical field [0001] The invention relates to the technical field of herbicides, in particular to a herbicide composition for treating stems and leaves in cotton fields, and also relates to its application. Background technique [0002] Cotton is the main economic crop in my country, with an annual planting area of ​​more than 5 million hectares 2 , accounting for 26% of the total area of ​​commercial crops, is an important pillar industry of the national economy. Weeds in cotton fields have seriously affected the normal growth of cotton due to competition with cotton for glory, water, nutrients, and parasitism of various diseases and insect pests. They have caused a reduction in lint production of about 250,000 tons throughout the year, and the production reduction of serious damage has reached as high as 60%. Therefore, effective control Weeds in cotton fields are one of the important measures to improve cotton yield and quality. According to the survey results of weed...
