Problems solved by technology

[0006] The purpose of the present invention is to solve the problems in the prior art that when a single pesticide is used alone, it is easy to produce resistance to weeds in cornfields and the actual control effect is poor, and to provide a high-efficiency, broad-spectrum, economical, safe, beneficial to cornfield weeds. Pesticide composition for integrated weed management

Embodiment 1

[0031] Formulation example 1: 27% chlorpyrazosulfuron-aminopyralid-nicotinesulfuron water-dispersible granules.

[0032]

[0033] 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 27% chlorpyrazosulfuron-aminopyralid-nicotine Longshui dispersible granules.

Embodiment 2

[0034] Formulation example 2: 30% chlorpyrazosulfuron-aminopyralid-nicotinesulfuron wettable powder.

[0035]

[0036] Add the above materials together into a conical mixer and mix them evenly, then pulverize them through a jet mill, and then mix the pulverized materials through a conical mixer. The fineness of the mixed materials is 98% and passes through a 600-mesh standard sieve to obtain 30% Clopyrazosulfuron, aminopyralid, nicosulfuron wettable powder.

Embodiment 3

[0037] Formulation example 3: 20% chlorpyrazosulfuron-aminopyralid-nicotinesulfuron suspension concentrate.

[0038]

[0039] The above formula is pre-pulverized according to the proportion, then put into a sand mill for grinding, and then prepared after high-shear mixing to obtain 20% chlorpyrazosulfuron-aminopyralid-nicotinesulfuron suspension concentrate.

[0040] Formulation example 4: 23% chlorpyrazosulfuron·aminopyralid·nicotinesulfuron oil suspension.

[0041]

[0042] 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 23% chlorpyrazosulfuron-...

Abstract

The invention discloses a pesticide composition containing halosulfuron-methyl, aminopyralid and nicosulfuron. Active ingredients are halosulfuron-methyl, aminopyralid and nicosulfuron. The pesticide composition has remarkable synergistic effects, has an obviously more excellent effect of preventing and removing annual weeds in cornfields than each single ingredient. Dosage of the active ingredients of the composition is obviously reduced in comparison with dosage of a single ingredient. In addition, weed control spectrum is broadened, weed resistance to herbicides is delayed, and environmental pollution is mitigated.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and specifically relates to a synergistic responsive pesticide composition with chlorpyrazosulfuron-methyl, aminopyralid and nicosulfuron-methyl as active ingredients, which is suitable for preventing and treating corn fields, especially purslane , gray-green quinoa are dominant annual weeds in cornfields. Background technique [0002] Halosulfuron-methyl (halosulfuron-methyl) is a sulfonylurea systemic agricultural compound, which can be absorbed by the stems, leaves and roots of plants. Weeds first stop growing and then die. It is mainly used to control annual broad-leaved weeds and sedges Branch weeds have special effects on Cyperus cyperi. [0003] Aminopyralid, a new type of pyridine carboxylic herbicide, is mainly used for the control of annual and perennial broad-leaved weeds, and is widely used in the control of weeds in mountains, grasslands, planting land and non-arable land. Aminop...
