Embodiment 1

[0082] Weigh 20% isoxaflutole, 20% thifensulfuron-methyl, 3% TERSPERSE 2700 (polycarboxyhydrochloric acid, produced by Huntsman, USA), 2% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde composition), 1% pull-off powder BX (sodium dibutylnaphthalene sulfonate), 1% K-12 (sodium lauryl sulfate), 3% soluble starch, 3% glucose, and kaolin are added to 100% by weight. 40% isoxaflutole-thifensulfuron-methyl water-dispersible granules are prepared from the above-mentioned raw materials through the conventional method for preparing water-dispersible granules, ie, mixing, ultrafine airflow pulverization, mixing, and granulation.

Embodiment 2

[0084] Weigh 12% isoxaflutole, 18% thifensulfuron-methyl, 3% TERSPERSE 2700, 4% sodium lignosulfonate, 1% pull-off powder BX, 1% K-12, 1% carboxymethylcellulose, Add 3% urea and diatomaceous earth to 100% by weight. 30% isoxaflutole-thifensulfuron-methyl water-dispersible granules are prepared from the above-mentioned raw materials through the conventional method for preparing water-dispersible granules, ie, mixing, ultrafine airflow pulverization, mixing, and granulation.

Embodiment 3

[0086] Weigh 8% isoxaflutole, 12% thifensulfuron-methyl, 4% TERSPERSE 2700, 1% pull open powder BX, 1% K-12, 0.8% dextrin, 5% ammonium sulfate, attapulgite to 100 % parts by weight. 20% isoxaflutole-thifensulfuron-methyl water-dispersible granules are prepared from the above-mentioned raw materials through the conventional method for preparing water-dispersible granules, ie, mixing, ultrafine airflow pulverization, mixing, and granulation.

Abstract

The invention discloses a herbicide composition containing isoxaflutole and thifensulfuron, and relates to the technical field of herbicide. The herbicide composition comprises the following active constituents: isoxaflutole and thifensulfuron, wherein the weight ratio of isoxaflutole to thifensulfuron is 99:1 to 1:99, and the optimal weight ratio is 10:1 to 1:10. The cumulant of isoxaflutole andthifensulfuron is 0.1% to 80% of the total weight of the composition, and the optimal cumulant of isoxaflutole and thifensulfuron is 2% to 20%. The herbicide composition is reasonable in constituents,with the control effect being superior to the activity of each singly applied constituent, has a synergistic effect, expands a weed control spectrum, controls corn field gramineae, cyperaceae and broadleaf weeds once the herbicide is applied, reduces the application frequency, reduces the control cost, slows down the occurrence weed resistance, has good safety for crops, and meets safety requirements on pesticide preparations. The herbicide composition has good control effects on most weeds, such as corn field gramineae weeds, broadleaf weeds and cyperaceae weeds, and has high safety for corns.

Description

technical field [0001] The invention belongs to the technical field of herbicides, in particular to a herbicide for preventing and treating annual weeds in corn fields, which is a binary herbicide composition composed of isoxaflutole and thifensulfuron-methyl. Background technique [0002] At present, chemical methods are commonly used for weed control. The chemical agents used are mainly acetochlor and atrazine, and the efficacy period of acetochlor is short. Some resistant weeds are less effective. In order to solve the above-mentioned disadvantages, the present invention selects several new drug ingredients with control and weeding effects, and develops a cornfield herbicide, which not only effectively kills the weeds after unearthed, but also It can control unearthed weeds and improve the weeding effect; the active ingredients in the herbicide of the present invention are combined within a certain range to have a good synergistic effect, the control effect is higher than...
