Problems solved by technology

[0006] At present, herbicides in cornfields are limited by the safety of crops, and their herbicidal spectrum is also limited. Using a single herbicide alone cannot completely and effectively control the occurrence of weeds in cornfields. Too long effective period, excessive dosage or uneven application will easily cause residual toxicity to current crops or subsequent crops

Abstract

The invention belongs to the field of pesticides, and discloses a herbicidal composition containing diflufenzopyr and picloram and application thereof. The herbicidal composition comprises the diflufenzopyr and the picloram serving as main active ingredients, the diflufenzopyr and the picloram account for 1 to 85 percent of the total mass of the herbicidal composition, and a mass ratio of the diflufenzopyr to the picloram is 1-80:1-80. The herbicidal composition can be applied to preparation of herbicides for controlling postemergence weeds in corn fields, and particularly has obvious effects when used for preparing herbicides for controlling gramineous weeds and broadleaf weeds in the corn fields. Compared with single-component herbicides, the herbicidal composition reduces dosage, delays the weed resistance, has broad herbicidal spectrums and acts for a long time on the premise of improving herbicide effect, and is safe for corns and afterculture crops.

Description

technical field [0001] The invention belongs to the field of pesticides, and relates to a post-emergence herbicidal composition in a corn field, in particular to a herbicidal composition containing diflufenzofen and picloram and an application thereof. 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 for about 36% of the country;...
