Problems solved by technology

Pesticides, like chemical fertilizers, have a low effective utilization rate during the application process, and a large amount of loss is one of the main reasons for the above-mentioned environmental hazards. However, the development of new pesticides is expensive and has a long cycle. Therefore, it is necessary to develop a high-efficiency, high-utilization rate. , Weed-killing pesticides with low environmental hazards

Abstract

The invention relates to the technical field of pesticides, and particularly provides a weeding composition which is prepared from the following raw materials: an active raw medicine, wherein the active raw medicine comprises refined glufosinate-ammonium and fluoroglycofen-ethyl; wherein the weight ratio of the refined glufosinate-ammonium to the fluoroglycofen-ethyl is 1: (0.1-50). According to the weeding composition, refined glufosinate-ammonium and fluoroglycofen-ethyl are compounded to serve as effective components, so that an excellent synergistic effect can be achieved, generation of herbicide resistance of weeds is delayed, the pesticide effect is enhanced, and the pesticide effect is rapid. The effective components are promoted to enter the active body efficiently, so that the pesticide dosage is reduced.

Description

technical field [0001] The present invention relates to the technical field of pesticides, in particular to a herbicidal composition, a compound herbicide and its application. Background technique [0002] Glufosinate-ammonium, also known as L-glufosinate-ammonium (L-glufosinate-ammonium), was first discovered in soil Streptomyces fermentation bialaphos, which is metabolized into L-glufosinate-ammonium and two molecules of amino acids in plants. L-Glufosinate-ammonium is the only natural allelopathic herbicide with C-P-C structure so far. Its herbicidal activity is about 4 times that of glyphosate and 2 times that of paraquat. It is a racemate glufosinate-ammonium (DL-type) more than 2 times. It is known that the glufosinate-ammonium sold in the market is a racemate, a mixture of 50% L-glufosinate-ammonium and 50% D-glufosinate-ammonium. Among them, D-glufosinate-ammonium is not only inactive, but introduces chiral pollutants into the environment. The glufosinate-ammonium...
