Abstract

The invention discloses a weeding compound containing glufosinate ammonium. The active ingredient of the weeding compound comprises glufosinate ammonium and d-limonene at mass ratio of (50:1)-(1:50).The compound disclosed by the invention has an obvious synergistic effect and can be used for preventing and removing weeds in wheat fields and corn fields.

Description

technical field [0001] The invention relates to a herbicidal composition, in particular to a herbicidal composition containing glufosinate-ammonium and its application for controlling crop weeds, and belongs to the technical field of pesticides. Background technique [0002] Wheat, barley and corn are important food crops. Corn is an annual herbaceous plant belonging to the Poaceae Zea genus, and it is the food crop with the largest total output in the world. Wheat is the general designation of Triticum plant, is a kind of gramineous plant widely planted all over the world, is the grain crops of total output the second in the world. In my country, wheat and corn are one of the three major food crops, occupy an important position in all food crops, and are the foundation of my country's agriculture. However, most of the wheat fields and corn fields in my country have historically suffered from weeds to varying degrees. These weeds are of many types, widely distributed, vigo...
