Embodiment

[0052] The composition of the present invention uses refined glufosinate-ammonium as the active ingredient (A), diphenyl ether herbicides and / or other herbicide active agents as the active ingredient (B), and forms a binary or multi-component compound. Weed control has obvious synergistic effect.

[0053] (1) Indoor toxicity test

[0054] Determination method: Indoor potted method, barnyardgrass, goosegrass, sedge, quinoa, stems and leaves are treated with a spray tower. 15 days after the drug, the fresh weight inhibition rate was measured and the ED was calculated. 50 Value, co-toxicity coefficient, in order to evaluate the herbicidal activity of the reagent.

[0055] Sun Peiyun co-toxicity coefficient method was used to evaluate the joint action mode of binary herbicides, the formula is as follows:

[0056]

[0057] In the formula:

[0058] ATI—measured toxicity index of mixture;

[0059] S—ED50 / 90 of standard medicine;

[0060] M—ED50 / 90 of the mixture;

[0061] T...

Abstract

The invention discloses a weeding composition and application thereof. The weeding composition comprises an active component A and an active component B, wherein the active component A is fine glufosinate ammonium; the active component B comprises one or more of diphenyl ether weedicides; the weight ratio of the active component A to the active component B is (1-20) to (80-1); the weeding composition can be used for controlling grass family weeds, broadleaf weeds and sedge family weeds. According to the weeding composition, multiple active components are compounded; the weeding composition israpid in pesticide effect and is capable of expanding weed control spectrum and improving the environment compatibility.

Description

technical field [0001] The invention relates to a herbicidal composition, in particular to a herbicidal composition containing refined glufosinate-ammonium, and its application in agriculture. Background technique [0002] The chemical name of refined glufosinate-ammonium is 4-[hydroxyl (methyl)phosphono]-L-homoalanine, which is easily soluble in water but not easily soluble in organic solvents. It is stable to light and has a melting point of 214-216°C. The molecular formula is: C 5 h 12 NO 4 P; Molecular weight: 181.1; Structural formula: [0003] [0004] Glufosinate-ammonium is a non-conductive contact herbicide. It controls weeds by inhibiting glutamine synthetase, which leads to nitrogen metabolism disorder in plants, nitrogen accumulation poisoning, and then hinders chloroplast synthesis and photosynthesis, eventually leading to plant death. . Refined glufosinate-ammonium has the advantages of low toxicity, high safety, wide herbicidal spectrum, high activity ...
