Problems solved by technology

In recent years, the harm of weeds on various economic crops such as soybeans has become more and more serious, and due to the abuse of herbicides, weeds have become more and more resistant to pesticides, resulting in a decrease in the weed control effect year by year
Some single agents such as metolachlor (Metolachlor) have good effects on most annual monocotyledonous weeds, but the effect on dicotyledonous weeds is not ideal under the recommended dosage, while Terbutryn (Terbutryn) It has good effect on most annual dicotyledonous weeds, but the effect on monocotyledonous weeds is not ideal. Therefore, there is a need for a dryland crop herbicide with better control effect and wider herbicidal spectrum

Abstract

The present invention relates to a herbicidal composition containing metolachlor and terbutine, which uses metolachlor and terbutine as active components, and the weight ratio of the active components is metolachlor: terbutine =1-8:1-8. The invention has the advantages of low toxicity, weak sensitization and low toxicity to humans and animals; wide herbicidal spectrum and remarkable weed control and synergistic effect, and is especially suitable for the control of various crops, especially various weeds in soybean fields.

Description

【Technical field】 [0001] The present invention relates to a kind of herbicidal composition, which contains the active ingredient composed of metolachlor and terbuthine. 【Background technique】 [0002] The crop yield is reduced due to the damage of weeds, so it is necessary to apply a large amount of herbicides every year for weed control to recover the loss of crop yield. In recent years, the harm of weeds on various economic crops such as soybeans has become more and more serious, and due to the abuse of herbicides, weeds have become more and more resistant to pesticides, resulting in a decrease in the weed control effect year by year. Some single agents such as metolachlor (Metolachlor) have good effects on most annual monocotyledonous weeds, but the effect on dicotyledonous weeds is not ideal under the recommended dosage, while Terbutryn (Terbutryn) It has a good effect on most annual dicotyledonous weeds, but the effect on monocotyledonous weeds is not ideal. Therefore,...
