Embodiment 1

[0024] Determination of combined effects of glyphosate and aryloxyphenoxypropionic acid herbicides on goosegrass

[0025] The test agent of the present invention: 30% (w / w) glyphosate aqueous solution; 108 g / liter gazolone emulsifiable concentrate; 15% (w / w) fluazifop-ethyl emulsifiable concentrate.

[0026] The test material of the present invention is collected from the resistant goosegrass population of Ningxi Town, Zengcheng District, Guangzhou City, Guangdong Province.

[0027] Medicament preparation of the present invention:

[0028] Glyphosate solution: Use a 1mL pipette to draw 200, 300, and 400mL / mu of 30% glyphosate solution for use;

[0029] Gai Caoneng solution: Use a 100 μL pipette gun to absorb 40, 60, and 80 mL / mu of 108 g / L Gai Caoneng EC for use;

[0030] Refined fluazifop solution: use 100 μL pipette gun to absorb 50, 60, 70 mL / mu of 15% fluazifop-ethyl emulsifiable concentrate for use.

[0031] Test method of the present invention: place the nutrient soil...

Abstract

The invention discloses a glyphosate and aryloxy phenoxypropionic acid herbicide composition and application thereof, and belongs to the technical field of pesticides. The effective ingredients of the composition are glyphosate and aryloxy phenoxypropionic acid herbicide, wherein the mixing ratio of glyphosate to haloxyfopmethy and the mixing ratio of glyphosate to fluazifop-p-butyl are respectively (7-28):1 and (5-16):1, the grass killing speed of the composition can be improved by 2-4 times, most eleusine indica having herbicide resistance on glyphosate can be killed, and the effect of the composition is superior to that of single dosage of glyphosate or aryloxy phenoxypropionic acid herbicide; and types with combined effect on eleusine indica have addition effect under different mixing combinations, the number of dosing times can be remarkably reduced, dosage of pesticide can be reduced, pollution for the environment caused by herbicides can be reduced, the problem of herbicide resistance of eleusine indica on glyphosate can be effectively controlled, and the service life of glyphosate can be prolonged. The glyphosate and aryloxy phenoxypropionic acid herbicide composition has an important meaning to comprehensive prevention and control on eleusine indica.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a composition of glyphosate and aryloxyphenoxypropionic acid herbicides and an application thereof. Background technique [0002] Glyphosate (glyphosate) is an organophosphorus herbicide with systemic and broad-spectrum killing characteristics. Glyphosate can inhibit the shikimic acid pathway in plants, blocking the reaction of phosphoenolpyruvate and shikimate-3-phosphate to generate 5-enolpyruvate-3-phosphoshikimate, resulting in a large amount of accumulation in plants Shikimic acid prevents the biosynthesis of the aromatic amino acids tryptophan, tyrosine, and phenylalanine, which ultimately inhibits plant growth and causes death. Glyphosate is absorbed through stems and leaves, and can control annual and perennial weeds in non-arable land, orchards, woodlands, etc. [0003] Goosegrass (Eleusine indica (L.) Gaertn.) has a wide distribution and is a worldwide ...
