Embodiment 1

[0016] Bioassay Example 1: Determination of the joint effect of high-efficiency haloxyfop-p-p and cloxazone mixed with weeds.

[0017] Test material: barnyard grass[ Echinochloa crusgalli (L.) Beauv. ] (Seeds collected in the field for preservation). Amaranth [ Amaranthus retro of Zex us ], (seeds collected in the field for preservation).

[0018] Test equipment: controllable light incubator; POTTER precision laboratory spray tower; electronic balance (sensitivity 0.1mg); micropipette gun, etc.

[0019] Test method: first weigh a certain mass of 95% high-efficiency haloxyfop-pylene technical product and 97.5% chlorester-sulfuramide technical drug, add acetone to fully dissolve it, dilute it with 0.1% Tween 80 aqueous solution, and prepare single doses respectively For the mother liquor, set a series of proportions according to the purpose of mixing, and set 5 to 7 concentration gradients for each proportion.

Embodiment 1

[0028] Formulation Example 1 : 30% high-efficiency fluroxyfop-sulfafelam oil suspension concentrate.

[0029] High-efficiency flurifop-p-methyl 17%, chlorester-sulfrazone 13%, emulsifier fatty alcohol polyoxyethylene ether 4%, calcium dodecylbenzenesulfonate 5%, tristyrylphenol polyoxyethylene polyoxypropylene Ether 3%, antifoaming agent epoxidized soybean oil 1%, antifreeze agent glycerin 0.5%, and the balance is methylated vegetable oil. Add the above formulas into the mixing tank in sequence according to the proportion, and after stirring evenly, a 30% high-efficiency haloxyfop-sulfafelam oil suspension concentrate is prepared.

[0030] This embodiment is used for preventing and controlling annual weeds in soybean fields. The dosage of 30% high-efficiency fluroxyfop-sulfentrazone oil suspension concentrate is 10 g / mu mixed with water and sprayed, and the control effect is 97.4% 20 days after the medicine. The dosage of 6.9% high-efficiency haloxyfop water emulsion is 40 ...

Embodiment 2

[0032] Formulation Example 2 : 15% high-efficiency haloxyfop-sulfentrazone wettable powder.

[0033] High-efficiency haloxyfop-methyl 10%, sulfentrazone 5%, wetting agent pull-off powder 3%, dispersant naphthalenesulfonate formaldehyde condensate 6%, filler talcum powder 15%, and the balance filler kaolin. The above formula is coarsely pulverized in proportion, put into a mixer and mixed uniformly, and then jet pulverized to obtain 15% high-efficiency fluroxyfop-chlorester-sulamed wettable powder.

[0034] This embodiment is used for controlling annual weeds in soybean fields. The dosage of 15% high-efficiency fluroxyfop-sulfentrazone oil wettable powder is 30 g / mu mixed with water and sprayed, and the control effect is 94.1% after 20 days of application. The dosage of 6.9% high-efficiency haloxyfop water emulsion is 40 g / mu mixed with water and sprayed, and the control effect is 68.2% after 20 days of application. The dosage of 84% cloxazone-sulam water-dispersible granule...

Abstract

The invention discloses a pesticide composition containing high-efficiency haloxyfop and cloransulammethyl. The pesticide composition comprises active ingredients of high-efficiency haloxyfop and cloransulammethyl, wherein the weight part ratio of the high-efficiency haloxyfop and the cloransulammethyl is 10:1-1:10; the total weight percentage of the high-efficiency haloxyfop and the cloransulammethyl in the pesticide composition is 10-80%. The pesticide composition disclosed by the invention is suitable for preventing and killing off annual weeds in soybean fields and is safe for the soybeans. According to the invention, manpower and material resources are saved, the auxiliary usage is reduced and the pollution of the pesticide to the environment is reduced.

Description

technical field [0001] The pesticide composition involved in the present invention uses high-efficiency haloxyfop-op and clofensulfame as active ingredients, and is used for preventing and controlling farmland weeds, especially for controlling annual weeds in soybean fields. Background technique [0002] High-efficiency methoxyfop, English common name haloxyfop-R-methyl , a phenoxycarboxylic acid herbicide, is a post-emergence selective herbicide. After the treatment of the stems and leaves, it can be quickly absorbed by the leaves of grasses and spread to the whole plant, inhibiting the plant meristems and killing grasses. The pesticide sprayed into the soil is easily absorbed by the roots and can also play a herbicidal role. The average half-life in the soil is 55 days. Compared with haloxyp-op, the high-efficiency haloxyfop-pyl replaces the ethoxyethyl group in haloxyfop-op with methyl in structure; and because the a-carbon of propionic acid in the haloxyfop-op structure...
