Description
Technical Field
The invention relates to the field of weeding, and in particular relates to a water dispersible granule containing glufosinate-ammonium, fluoroglycofen-ethyl and quizalofop-p-ethyl.
Background
Glufosinate belongs to phosphonic acid herbicides and can inhibit glutamine synthetase in plant nitrogen metabolic pathways, so that metabolism of plants is interfered, and the plants die. The glufosinate-ammonium has the characteristics of wide herbicidal spectrum, low toxicity, high activity, good environmental compatibility and the like, and the speed of playing the active action is slower than that of paraquat and is better than that of glyphosate. At present, the herbicide is a non-selective herbicide coexisting with glyphosate and paraquat, and has a wide application prospect. Many weeds are sensitive to glufosinate and can be used as a substitute for glyphosate in areas where glyphosate is resistant. Fluoroglycofen-ethyl is a diphenyl ether herbicide, is a protoporphyrin oxidase inhibitor, and can only exert efficacy under the condition of illumination once being absorbed by plants. The compound reacts with molecular chlorine to generate a compound tetrapyrrole which is toxic to plant cells, and the tetrapyrrole is accumulated to act. During the accumulation process, the plant cell membrane is completely lost, and then the leakage of the cell contents is caused. At present, the herbicide obtained by compounding glufosinate-ammonium and fluoroglycofen-ethyl in the market has enhanced weeding effect, but the dosage of the herbicide is still higher, and the pesticide effect is unstable.
