Embodiment 4

[0031] Formulation example 4: 12% promasulfuron-methyl-cyhalofop-p-ethyl oil suspension concentrate

[0032]

[0033] Put the above materials (except organic bentonite) into the reaction kettle mixer together, stir for 2 hours, open the feed valve at the bottom of the kettle, inject the materials into the multi-stage sand mill for grinding, and the fineness of the ground materials is 98% through 1- After 5um, the material is discharged, and the material is put into a high-shear emulsification kettle together with the pre-dissolved organic bentonite. After emulsification, it can be made into 12% promethazone-methyl-cyhalofop-ethanol with good flowability Fenoxaprop-ethyl oil suspension concentrate.

[0034] Formulation example 5: 16% promasulfuron-methyl-cyhalofop-ethyl-oxaprop-ethyl aqueous emulsion.

[0069] Bioassay Example 2: Field efficacy test of promasulfuron-methyl, cyhalofop-ethyl, and fenoxaprop-p-p-ethyl in controlling annual weeds in paddy fields

[0070] Table 7. Field efficacy test results of promasulfuron-methyl, cyhalofop-ethyl, and fenoxaprop-ethyl compositions for controlling annual weeds in paddy fields

[0071]

[0072] In summary, the composition of the present invention is reasonable, and the ternary combination of promazone-methyl, cyhalofop-ethyl, and fenoxaprop-ethyl has a synergistic response to target weeds, and the effect of controlling annual weeds in paddy fields is excellent. The conventional pesticides currently available on the market provide excellent weed control solutions for rice fields, and are suitable for controlling annual weeds in rice fields.

Abstract

The invention relates to a herbicidal composition containing propyrisulfuron, cyhalofop-butyl and fenoxaprop-P-ethyl. The herbicidal composition contains active ingredients of propyrisulfuron, cyhalofop-butyl and fenoxaprop-P-ethyl, wherein the percentage by weight of propyrisulfuron in the herbicidal composition is 0.1%-30%, the percentage by weight of cyhalofop-butyl in the herbicidal composition is 0.1%-40%, and the percentage by weight of fenoxaprop-P-ethyl in the herbicidal composition is 0.1%-20%. The herbicidal composition provided by the invention has a synergistic effect, the effect of controlling annual weeds in a paddy rice field is obviously better than the effect when a respective agent is used alone, the herbicide controlling spectrum is expanded, the dosage is simultaneously reduced, the production of drug resistance of the weeds is delayed, and the environmental pollution is reduced.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a synergistic herbicidal composition with promethazone-methyl, cyhalofop-ethyl and fenoxaprop-ethyl as active ingredients, which is suitable for controlling annual weeds in paddy fields . Background technique [0002] Propyrisulfuron, a selective broad-spectrum herbicide, has a good control effect on weeds resistant to sulfonylurea herbicides, and is effective on older barnyardgrass, sedge, and broad-leaved grass. Can be foliar spray, shake application. [0003] Cyhalofop-buty is the only one among the aryloxyphenoxypropionic acid herbicides that is highly safe to rice. Like other varieties in this category, it is also a systemic conductive herbicide. Absorbed by the leaves and leaf sheaths of the plant, conducted by the phloem, and accumulated in the meristematic tissue area of ​​the plant, it resists acetyl-CoA carboxylase (ACCase), stops the synthesis of fatty...
