Problems solved by technology

Although dinitroaniline herbicides such as trifluralin and pendimethalin have certain effects on some annual small-seeded broad-leaf weeds, such as amaranth and quinoa, the control effect is far worse than that of grass weeds. weed ineffective

Embodiment 1

[0021] Cotton field soil treatment herbicide composition: water dispersible granule of pyrizachlor-oxyfluorfen (1:3) with 24% active ingredient by weight: weigh 6% pyrizachlor, 18% ethyl Oxyfluorfen, 3% polycarboxylate, 2% diffusing agent NNO, 3% pull-off powder BX (sodium butylnaphthalene sulfonate), 5% ammonium sulfate, 3% polyvinyl alcohol, diatomaceous earth to make up to 100 %. Mix the above raw materials evenly in a mixer, pulverize them with ultra-fine airflow, mix them, add water and knead them, then extrude and granulate, dry and sieve. Oxyfluorfen water dispersible granules.

Embodiment 2

[0023] Cotton field soil treatment herbicide composition: water dispersible granule of pyrizachlor-oxyfluorfen (1:4) with 10% active ingredient by weight: weigh 2% pyrizanit, 8% ethyl Oxyfluorfen, 4% polycarboxylate, 2% sodium lignosulfonate, 3% sodium lauryl sulfate, 5% urea, 4% gel, attapulgite make up to 100%. Mix the above raw materials evenly in a mixer, pulverize them with ultra-fine airflow, mix them, add water and knead them, then extrude and granulate, dry and sieve, and after passing the inspection, you can get 10% pyrizachlor-B Oxyfluorfen water dispersible granules.

Embodiment 3

[0025] Cotton field soil treatment herbicide composition: water dispersible granule of pyrizachlor-oxyfluorfen (1:5) with 42% active ingredient weight percentage: weigh 7% pyrizanit, 35% ethyl Oxyfluorfen, 5% polycarboxylate, 2% diffusing agent NNO, 3% alkylphenol polyoxyethylene ether, 2% carboxymethyl cellulose, 5% glucose, and kaolin make up to 100%. Mix the above raw materials evenly in a mixer, pulverize them with ultra-fine airflow, mix them, add water and knead them, then extrude and granulate, dry, and sieve. Oxyfluorfen water dispersible granules.

Abstract

The invention belongs to the technical field of herbicides, in particular discloses a herbicide composition for treating cotton field soil, and also discloses an application of the herbicide composition. The herbicide composition for treating the cotton field soil is obtained by blending active ingredients with auxiliary materials, wherein the active ingredients comprise pyrithiobac-sodium and oxyfluorfen, and the weight ratio of the pyrithiobac-sodium to the oxyfluorfen is 1:(3-7). The herbicide composition for treating the cotton field soil is reasonably compounded, is obvious in synergistic effect, good in herbicidal effect and wide in herbicide controlling spectrum. The herbicide composition has significant control and herbicidal effects on main occurrences of grassy weeds and broad-leaf weeds in a cotton field, reduces the drug delivery times, delays resistance of weeds, and has high crop safety.

Description

technical field [0001] The invention relates to the technical field of herbicides, in particular to a cotton field soil treatment herbicide composition, 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 weeds in cotton fields,...
