Embodiment 1

[0042] Weigh 50% isoproturon, 3% pinoxaden, 1% acesulfame, 2% pentaclofen, 5% calcium polycarboxylate, 2% sodium alkylphenol polyoxyethylene ether sulfonate, 2% % sodium lauryl sulfate, 5% talcum powder, light calcium added to 100% by weight. The above raw materials were mixed and air-jet pulverized to obtain 54% pinoxaden-isoproturon-pymesulam wettable powder.

Embodiment 2

[0044] Weigh 20% isoproturon, 20% pinoxaden, 15% acesulfame, 1.5% pentaclofen, 4% sodium lignosulfonate, 3% alkylphenol polyoxyethylene ether phosphate, 2 % sodium polycarboxylate, 2% sodium alkylsulfonate, 3% white carbon black, kaolin added to 100% by weight. The above-mentioned raw materials were mixed and air-jet pulverized to obtain 55% isoproturon. pinoxaden. acesulfame wettable powder.

Embodiment 3

[0046] Weigh 40% isoproturon, 2.5% pinoxaden, 0.5% acesulfame, 2% pentaclofen, 3% polycarboxylate T36, 1% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensation thing), 1% sodium dodecylbenzenesulfonate, 1% sodium alkylsulfonate, 2% starch, and talcum powder added to 100% by weight. 43% isoproturon · pinoxaden · acesulfame water dispersible granules were prepared by the conventional method for preparing water dispersible granules from the above raw materials, that is, mixing, ultrafine airflow pulverization, mixing and granulation.

Abstract

The invention discloses a ternary herbicidal composition containing isoproturon and its application. The effective active ingredients are composed of the first active ingredient isoproturon, the second active ingredient pinoxaden and the third active ingredient acesulfame , the mass ratio of isoproturon, pinoxaden and acesulfame is (0.1-90): (0.1-90): (0.1-90). The composition can be formulated into agriculturally acceptable water-dispersible granules, wettable powders, suspensions, and dispersible oil suspensions. The composition of the present invention is reasonable, and the herbicidal effect is good in the wheat field, and its activity and herbicidal effect are not a simple superposition of the activities of each component. Moreover, it has a significant synergistic effect, reduces the dosage, increases the herbicidal spectrum, and is safe for crops.

Description

technical field [0001] The invention relates to a wheat field herbicide composition, which is composed of active ingredients isoproturon, pinoxaden and acesulfame and auxiliary agents, and belongs to the technical field of compound pesticides. Background technique [0002] Isoproturon, the English name is isoproturon, the chemical name is: 3-(4-isopropylphenyl)-1,1-dimethylurea. Developed by Hested in Germany and produced by Jiangsu Changlong Chemical Factory in China, it is a root-absorbing herbicide product. After the drug is absorbed by the roots of the plant, it is transported and accumulated in the leaves, inhibiting photosynthesis and causing weeds die. Sufficient sunlight, high temperature, and high soil moisture are conducive to the efficacy of the medicine. It can be used to control annual gramineous weeds and some dicotyledonous weeds in wheat fields, and it has special effects on controlling hard grass, weeds, and arpeggios. It has a wide spectrum of weeding, a...
