Problems solved by technology

[0005] The object of the present invention is to provide a herbicidal composition containing flunmezone-sulam for the alfalfa field, to solve the problem that with the gradual increase of weed resistance, the control effect of existing chemical agents on weeds is also gradually decreasing ; Although increasing the dosage of pesticide spraying can improve the control effect on weeds, it is easy to cause phytotoxicity to alfalfa and affect its growth

Embodiment 1

[0014] Example 1 : Screening of pesticides for weed control in alfalfa field

[0015] 1. Weeds for test: Crabata (Digitaria sanguinalis) seeds were collected from the alfalfa base of Hebo Grass Industry Co., Ltd., Huayuankou Town, Huiji District, Zhengzhou City.

[0016] 2. Test reagents: 93.6% fluketonesulfuron technical, 97% rimsulfuron technical, 98% indoxabutamate technical, 97.5% chlorate sulfentrazone technical, the above pharmaceuticals are all in the market sale;

[0017] Dissolve the test agent with dimethyl sulfoxide solvent, then dilute it with 0.1% Tween-80 aqueous solution, prepare a single-dose mother liquor, set up multiple groups of proportions, and set each single agent and proportioning mixture according to the equal ratio method. 6 mass concentration gradients.

Abstract

The invention belongs to the technical field of pesticides, and particularly relates to a triafamone-containing weeding composition for an alfalfa field. The invention relates to a triafamone-containing weeding composition for a medicago sativa field. The effective component of the weeding composition is formed by compounding triafamone with amidosulfuron-methyl, indolinone-ethyl or cloransulam-methyl. After triafamone is compounded with amidosulfuron methyl, indolone-ethyl or cloransulam-methyl in the weeding composition, a synergistic effect is shown in a certain mass ratio range, and compared with a single component, the weeding composition has the advantages that the control effect on weeds such as crab grass in a purple alfalfa field can be improved, so that the application amount of pesticides can be reduced, and the generation of phytotoxicity can be reduced.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a herbicidal composition containing flufenoxsulam for alfalfa fields. Background technique [0002] Alfalfa (Medicago sativa) is a leguminous perennial herb with the advantages of high yield, rich in protein, excellent grass quality, strong biological nitrogen fixation and good palatability. It plays an irreplaceable role in animal husbandry, especially dairy cattle industry. . The occurrence of weeds in alfalfa fields is serious, especially the vicious weeds such as beef tendon, crabgrass, snakehead and Cyperus officinalis grow rapidly, and it is difficult to prevent and control, which seriously affects the yield and quality of alfalfa. At present, chemical agents are mainly used to control weeds in alfalfa fields, such as quizalofop-p-ethyl, imazethapyr and sulfentrazone. gradually decreasing. Although increasing the pesticide spraying dose can improve the con...
