Abstract

The invention discloses a herbicidal composition containing rimsulfuron-methyl and oxafluzone, which contains active components rimsulfuron-methyl and oxaflumezone in a mass ratio of 1:50-60:1. The control effect of the herbicidal composition of the present invention is higher than that of the components rimsulfuron-methyl and oxaflumezone when applied alone, has obvious synergistic effect, greatly reduces the dosage of active ingredients, and is safe for crops. At the same time, the herbicidal spectrum has been expanded, and it has a good control effect on grass weeds and broad-leaved weeds such as crabgrass, goosegrass, foxtail, and lily in corn fields.

Description

[0001] technical field [0002] The invention relates to a herbicide for controlling weeds in corn fields, in particular to a herbicidal composition containing rimsulfuron-methyl and oxaflumezone, and belongs to the technical field of pesticides. [0003] Background technique [0004] In recent years, China's corn planting area has increased by an average of 2% annually. In 2010, the national corn planting area was about 30 million hectares, which is the second largest crop after rice. How to use new high-efficiency and environmentally friendly pesticides to control weed damage in corn fields is a major challenge faced by the plant protection community. [0005] Amidosulfuron, also known as Allstar, Hoestar, Hoe0750032, English name Amidosulfuron, chemical name 1-(4,6-dimethoxy-2-pyrimidinyl)-3-(N-methylsulfonamidesulfonyl )-urea. It is a sulfonylurea high-efficiency herbicide. Weeds absorb through stems and leaves to inhibit some cell division, and the plants stop growin...
