Problems solved by technology

[0005] At present, chemical control is the leading measure for the control of weeds in farmland. The herbicides used to control grass weeds, broad-leaved weeds and sedge weeds are single-agent clopyralid, clopyralid and amilopyral Mainly, long-term single use can easily lead to decreased sensitivity of grass weeds, broad-leaved weeds and sedge weeds, resulting in resistance problems
[0006] In addition, pesticides, like chemical fertilizers, have a low effective utilization rate in the process of application, and a large amount of loss is one of the main reasons for the above-mentioned environmental hazards

Abstract

The invention provides ternary weeding composition containing C5H12NO4P. The ternary weeding composition containing C5H12NO4P comprises an active component and an auxiliary component, wherein the active component is prepared from C5H12NO4P, clopyralid and fluoroglycofen-ethyl in the mass ratio being (10-30): (1-10):1.

Description

Technical field [0001] The invention belongs to the field of agricultural chemical applications. Specifically, the invention relates to a three-component herbicidal composition containing refined glufosinate-ammonium. Background technique [0002] The chemical formula of glufosinate ammonium is C 5 H 12 NO 4 P, the formula weight is 181.27, the chemical name is 4-[hydroxy(methyl)phosphono]-L-homoalanine, it is L-type glufosinate, easily soluble in water, not easily soluble in organic solvents, light sensitive Stable, with a melting point of 214-216°C, it is a highly efficient, low-toxic, non-selective contact phosphate herbicide. Precise glufosinate-ammonium is L-form glufosinate-ammonium, and its herbicidal activity is twice that of the racemic DL-form glufosinate-ammonium mixture. Glufosinate-ammonium inhibits glutamine synthetase, causing nitrogen metabolism disorders in plants, accumulated ammonia poisoning, and then chloroplast synthesis, photosynthesis is blocked, ...
