Embodiment 1

[0041] Weigh 30% fluroxypyr, 20% cyhalofop-ethyl, 5% quinclorac, 5% calcium sulfonate of alkylnaphthalene formaldehyde condensate, 3% sodium alkylphenol polyoxyethylene ether sulfonate, 3% sodium alkylnaphthalene sulfonate, 5% attapulgite, clay added to 100% by weight. The above raw materials are mixed and jet crushed to obtain 55% wettable powder of fluroxypyr-cyhalofop-methyl-quinclorac.

Embodiment 2

[0043] Weigh 15% fluroxypyr, 10% cyhalofop-ethyl, 20% quinclorac, 10% calcium sulfonate of alkylnaphthalene formaldehyde condensate, 4% sodium alkylphenol polyoxyethylene ether sulfonate, 4% sodium alkylsulfonate, 5% light calcium, and attapulgite are added to 100% by weight. The above raw materials are mixed and air-jet pulverized to obtain 40% fluroxypyr-cyhalofop-ethyl-quinclorac wettable powder.

Embodiment 3

[0045] Weigh 5% fluroxypyr, 15% cyhalofop-ethyl, 10% quinclorac, 8% sodium lignosulfonate, 5% sodium polycarboxylate, 4% sodium alkylsulfonate, 3% white Carbon black and kaolin are added to 100% by weight. The above-mentioned raw materials are mixed and air-jet pulverized to obtain 30% fluroxypyr-cyhalofop-ethyl-quinclorac wettable powder.

Abstract

The invention discloses a three-ingredient weeding composition and application thereof. Effective active ingredients consist of a first active ingredient of fluroxypyr, a second active ingredient of cyhalofop-butyl and a third active ingredient of quinclorac according to a mass ratio of (1 to 90): (1 to 90): (1 to 90). The composition can be used for preparing agricultural allowable water dispersible granules, wettable powder, suspending agents, missible oil and dispersible oil suspending agents. The three-ingredient weeding composition has the advantages that the ingredients are reasonable; the weeding effect on paddy field is good; in addition, the activity and the weeding effect are not the simple overlapping effect of the activity of each ingredient. Compared with the existing single-ingredient preparation or two-ingredient compounding preparation, the three-ingredient weeding composition has the advantages that the obvious weeding effect is achieved; in addition, the obvious synergistic effect is also achieved; the herbicide controlling spectrum is increased; the weed prevention and removal cost can be reduced; the safety on crops is high.

Description

technical field [0001] The invention relates to a three-component herbicidal composition for paddy fields, which is composed of active ingredients fluroxypyr, cyhalofop-ethyl, quinclorac and auxiliary agents, and belongs to the technical field of compound pesticides. Background technique [0002] Fluroxypyroxyacetic acid, the English name is fluroxypyr, the chemical name is: 4-amino-3,5-dichloro-6-fluoro-pyridine-2-pyridineoxyacetic acid 1-methyl-heptyl ester. Systemic conduction type post-emergence herbicide. After the drug is quickly absorbed by the plants, the sensitive plants will respond to typical hormone herbicides, and the plants will be deformed and twisted. Temperature has no effect on the final effect of its weeding, but affects the speed of its efficacy. Generally, when the temperature is low, the drug effect is slow, which can stop the growth of the plant after poisoning, but it does not die immediately; the plant dies soon after the temperature rises. The le...
