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. Herbicidal composition for integrated weed management

Embodiment 1

[0014] Formulation example 1: 25% chlorpyrazosulfuron-aminopyralid-sulfuron-methyl water-dispersible granules.

[0015]

[0016] 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, dry and sieve to obtain 25% chlorpyrazosulfuron-aminopyralid-sulfonesulfur Longshui dispersible granules.

Embodiment 2

[0017] Formulation example 2: 19% chlorpyrazosulfuron-aminopyralid-sulfuron-methyl wettable powder

[0018]

[0019] 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 19% Clopyrazosulfuron · aminopyralid · rimsulfuron wettable powder.

Embodiment 3

[0020] Formulation example 3: 19% clopyrazosulfuron-aminopyralid-sulfuron-methyl suspension concentrate

[0021]

[0022] The above formula is pre-crushed according to the proportion, then added to a sand mill for grinding, and then prepared after high-shear mixing to obtain a 19% chlorpyrazosulfuron-aminopyralid-sulfuron-methyl suspension concentrate.

Abstract

The invention discloses a weeding composition for controlling and removing annual weeds in corn fields. Active ingredients of the composition are halosulfuron-methyl, aminopyralid and rimsulfuron. The weeding composition has a remarkable synergistic effect and has a more obviously excellent effect of controlling and removing annual weeds in corn fields than a 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, drug resistance of weeds is delayed, and environmental pollution is mitigated.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a synergistic response herbicidal composition with chlorpyrazosulfuron-methyl, aminopyralid and rimsulfuron-methyl as active ingredients, which is suitable for preventing and treating corn fields, especially sorrel leaves The annual weeds in the corn field are the dominant weeds of Polygonum spp. 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-...
