Problems solved by technology

[0004] Single-use drugs have disadvantages such as narrow herbicidal spectrum, large dosage, and weeds are prone to resistance, so their use is limited, and the compounding of two agents with different mechanisms of action is one of the effective ways to solve the above problems
There are no relevant reports on the compounding of thifensulfuron-methyl and pinoxaden and its dosage forms at home and abroad

Embodiment 163

[0024] Example 1 63% thifensulfuron-oxoxaden water-dispersible granules

[0025] The formula is: 3% thifensulfuron-methyl, 60% pinoxaden, 3% sodium polycarboxylate, 1.5% calcium lignosulfonate, 1% sodium lauryl sulfate, 1% sodium lignosulfonate, Disodium diamine tetraacetate 2%, ammonium sulfate 4.5%, urea 3%, corn starch added to 100%.

[0026] The preparation method is as follows: mix the thifensulfuron-methyl original drug, pinoxaden original drug, dispersant, wetting agent, chelating agent, disintegrating agent, and filler in a mixer, and pulverize it with a jet mill to a particle size of 400- After 600 mesh, mix evenly, knead and add water to 20-30wt% of the total amount of materials, carry out extrusion granulation, and dry at 50-60°C to make water-dispersible granules.

Abstract

The invention discloses a herbicidal composition of thifensulfuron-methyl and pinoxaden and an application thereof. The active ingredients of the composition are thifensulfuron-methyl and pinoxaden with a mass ratio of 1-20:1-20. The invention also provides a water-dispersible granule of thifensulfuron-methyl and pinoxaden and its application. Thifensulfuron-methyl and pinoxaden belong to two kinds of herbicides with different mechanisms of action. The mixture of the two will not conflict with each other, which can delay the emergence of weeds' resistance to pesticides, expand the weeding spectrum, and improve the weeding efficiency. The active ingredients of the medicine have a good synergistic effect within the preferred range, which can improve the weeding effect; the preferred water-dispersible granules of the present invention have a small dosage, which reduces the residue of the medicine in the soil and is beneficial to the sustainable development of the environment; The composition has a wide herbicidal spectrum, can control most of the broad-leaved and gramineous weeds in the wheat field, and can achieve the effect of "eliminating grasses and grasses" with one application.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a herbicidal composition containing thifensulfuron-methyl and pinoxaden and its preparation method and application, belonging to the technical field of pesticides. Background technique [0002] Thifensulfuron methyl, chemical name: 3-(4-methoxy-6-methyl-1,3,5-triazin-2-ylcarbamoylsulfonyl)thiophene-2-carboxylic acid . Thifensulfuron-methyl is a high-efficiency selective post-emergence stem and leaf treatment agent, which is mainly absorbed and conducted through the leaves and roots of weeds. It is mainly used for the control of annual and perennial broad-leaved weeds such as soybeans, wheat, and corn, such as Abutilon , Amaranthus retroflexus, Swampweed, Humulus, Kochia, Chickweed, Buliuxing, Popona, Purslane, Solanum nigrum, etc., but the control effect on grass weeds is not significant. [0003] Pinoxaden, chemical name: 2,2-dimethyl-propiolic acid 8-(2,6-diethyl-4-methyl-phenyl)-9-...
