Herbicide composition of propyrisulfuron, pyribenzoxim and fenoxaprop-P-ethyl

[0022] Formulation Example 1: 35% promethazine, sulfamethoxazole, fenoxafen water dispersible granules.

[0023]

[0024] The above materials are added together into the conical mixer and mixed evenly, and then pulverized by the jet pulverizer. The pulverized materials are then mixed in the conical mixer. The fineness of the mixed material is 98% through a 600-mesh standard sieve and added to the kneader. Knead into plastic material, and finally put this material into the extrusion granulator to extrude and granulate. After granulation, 35% promethazulfuron, pyrimifen, quinoxazole can be obtained after drying and sieving. He Cao Ling water dispersible granules.

[0025] Formulation Example 2: 30% promethazine, sulfamethoxazole, fenflufen-ethyl wettable powder.

[0026]

[0027] Add the above materials together into the conical mixer and mix them evenly, then pulverize by the jet mill, and then mix the pulverized materials in the conical mixer. Trisulfuron-methyl, pyriflufen-ethyl, fenoxaprop WP.

[0028] Formulation Example 3: 20% promethazine, sulfamethoxazole, fenflufen-ethyl suspension.

[0029]

[0030]

[0031] The above formula is pre-pulverized in proportion, and then added to a sand mill for grinding, and after being mixed with high shear, it is formulated to obtain a 20% promethazine, pyriflufen-ethyl and oxaflufen suspension.

[0032] Formulation Example 4: 12% promethazine, sulfamethoxazole, fenoxafen oil suspension.

[0033]

[0034] Add the above materials (except the organic bentonite) into the reactor mixer, stir for 2 hours, open the feed valve at the bottom of the kettle, and inject the materials into the mu

[0070] Bioassay Example 2: Field efficacy test of the composition of promethazine, pyriflufen-ethyl and fenoxafen for controlling annual weeds in paddy fields

[0071] Table 7. The results of the field efficacy test of the combination of rimsulfuron-methyl, pyrimifen, and oxaflutole for controlling weeds in paddy fields.

[0072]

[0073]

[0074] To sum up, the composition of the present invention is reasonable, and the ternary combination of promethazine, pyrimidine and oxaflufen has a synergistic response to the target weeds, and provides excellent weeds for paddy fields. Grass management solution, suitable for controlling annual weeds in paddy fields.
