Abstract

The invention discloses a synergistic herbicide composition containing rimsulfuron and clopyralid and application thereof. In the herbicidal composition, rimsulfuron and clopyralid serve as the main active ingredients, wherein the mass ratio of the rimsulfuron to the clopyralid is 1-80: 1-80. The synergistic herbicide composition can be used for preparing herbicide for controlling post-emergence weeds in corn field. Compared with the single-composition herbicide, the herbicide composition postpones the resistance of weeds, has a broad herbicide spectrum and acts for a long time on the premise of improving the herbicide effect, is safe for the corns and the afterculture crops, and particularly has an obvious effect of preventing various graminaccae and broadleaf weeds in the corn field.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to the field of herbicides, and relates to a binary compound of rimsulfuron-methyl and clopyralid. The herbicidal composition can be applied to post-emergence weeding in corn fields. Background technique [0002] Corn is not only an important food crop, but also an important feed crop. It is known as the "king of feed". In recent years, with the development of animal husbandry, food processing and wine making, the market demand continues to increase. my country is a major producer of corn in the world, with an annual planting area of ​​21.4 million ha 2 , accounting for 18.9% of the acreage of grain crops, ranking third after rice and wheat. It is divided into spring sowing and summer sowing. In the northern spring sowing corn area, mainly in the three northeastern provinces, Inner Mongolia and Ningxia, the planting area is stable at more than 6.5 million hectares, accounting fo...
