Embodiment 1

[0030] Example 1: Promethazone-methyl, cyhalofop-ethyl, penoxsulam and their compound barnyardgrass (Echinochloa crusgalli), Lee's grass (Leersia hexandra), water bamboo leaves (Murdannia triquetra), water onion ( Scirpus validus), Cyperus difformis indoor toxicity test.

[0031] According to the Colby method to evaluate the combination of herbicides (NY / T 1155.7-2006), the formula is as follows:

[0032] E 0 = A × B × C × . . . N 10 0 ( n - 1 )

[0033] In the formula:

[0034] A is the fresh weight inhibitory rate of promethazone-methyl to the target weeds when a certa...

Embodiment 2

[0060] Example 2: (40% promasulfuron-methyl-cyhalofop-methyl penoxsulam water-dispersible granules)

[0061]

[0062] Put the above materials together into the conical mixer and mix them evenly, and then crush them through the jet mill, and then mix the crushed materials through the conical mixer. Knead into a plastic material, and finally put the material into an extrusion granulator to extrude and granulate. After granulation, it is dried and sieved to obtain 40% promethazone-methyl-cyhalofop-ethyl according to the weight percentage · Penoxsulam water dispersible granules.

Embodiment 3

[0063] Example 3: (22% Promasulfuron-methyl Cyhalofop-Penoxsulam Suspension Concentrate)

[0064]

[0065] The above formula is pre-crushed according to the proportion, then added to the sand mill for grinding, and then prepared after high-shear mixing to obtain a 22% promarazine-methyl-cyhalofop-pentoxsulam suspension concentrate of the corresponding weight percentage .

Abstract

The invention relates to a weeding composition containing propyrisulfuron, cyhalofop-butyl and penoxsulam. The weeding composition comprises the following effective ingredients of propyrisulfuron, cyhalofop-butyl and penoxsulam in weight ratio of (1 to 30) to (1 to 50) to (1 to 30). The weeding composition has the advantages that the synergistic interaction function on weeds in the paddy field is realized, the weeding spectrum is expanded, the weed resistance risk is reduced, and the weeding composition is suitable for removing the annual weeds of the paddy field.

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 penoxsulam as active ingredients, which is mainly suitable for controlling annual weeds in paddy fields. Background technique [0002] Chemical weed control is one of the main means of weed control in paddy fields, and the use of a single compound herbicide can easily lead to weed resistance. At the same time, when weeds occur in paddy fields, the grass phases are complex, and grasses, sedges, and broad-leaved weeds are mixed, and the use of a single compound herbicide will show some defects and defects. Limitations, can not completely solve the weeds in farmland. The combination of different types of compound herbicides can expand the herbicidal spectrum, improve the actual effect, delay weed resistance, and save time and labor. [0003] Propyrisulfuron, chemical name: 1-(2-chloro...
