Embodiment 130

[0045] Example 1 30% isoxaflutole · sulfentrazone water dispersible granules

[0046] The formula is: 15% isoxaflutole, 15% sulfentrazone, 4% sodium naphtholsulfonate formaldehyde condensate dispersant, 4% sodium alkylphenolsulfonate, fatty alcohol polyoxyethylene ether wetting agent Sodium sulfate 1%, pull open powder BX 2%, disintegrant urea 3%, potassium sulfate 5%, kaolin supplement 100%.

[0047] The preparation method is as follows: add isoxaflutole, sulfentrazone, dispersant, wetting agent, disintegrating agent and filler into the mixer, mix evenly, and pulverize to 20-40μm granule by jet mill, and then Mix evenly, then add water for kneading, extrude the kneaded material into granules, and dry at 40-60°C to prepare 30% isoxaflutole·sulfentrazone water-dispersible granules.

Embodiment 2

[0048] Example 2 35% isoxaflutole · sulfentrazone water dispersible granules

[0049] The formula is: isoxaflutole 8.75%, sulfentrazone 26.25%, dispersant maleic acid-acrylic acid copolymer salt 3%, calcium lignosulfonate 1%, wetting agent alkylphenol polyoxyethylene ether sulfuric acid Sodium 1%, sodium lignosulfonate 1%, disintegrant sodium sulfate 2%, calcium chloride 3%, and organic bentonite make up 100%. The preparation method is the same as in Example 1.

Embodiment 340

[0050] Example 3 40% isoxaflutole · sulfentrazone water dispersible granules

[0051] The formula is: isoxaflutole 12%, sulfentrazone 28%, the dispersant is sodium methylene bis-naphthalene sulfonate 1%, polyoxyethylene-polyoxypropylene block copolymer 1%, the wetting agent is Sodium lauryl sulfate 1%, sodium alkylnaphthalene sulfonate 3%, disintegrant ammonium sulfate 12%, sodium chloride 3%, light calcium carbonate supplement 100%.

Abstract

The invention discloses an isoxaflutole/sulfentrazone-containing weedicide composition and application thereof. The composition is prepared by compounding isoxaflutole and sulfentrazone in a mass ratio of 1:(1-10) under favorable synergistic actions. The composition is capable of enhancing the drug effects, lowering the dosage, saving the economic cost, greatly reducing the consumption of the single active component, enhancing the safety for crops and reducing the agent residues in the environment; and the composition is also capable of postponing the generation of weed drug resistance and prolonging the service life of the agent, and has favorable effects on preventing and removing annual weed in the corn field.

Description

technical field [0001] The invention relates to a herbicidal composition, in particular to a herbicidal composition containing isoxaflutole and sulfentrazone and the application of the composition in controlling annual weeds in cornfields, belonging to the technical field of pesticides. Background technique [0002] Isoxaflutole is an isoxazole herbicide. It is an organic heterocyclic selective systemic pre-emergence herbicide used for soil treatment in upland crop fields such as corn and sugarcane. It mainly passes through the young roots of weeds. It works by absorption and conduction. After ingestion by sensitive weeds, it destroys the formation of chlorophyll by inhibiting p-hydroxypropiophenone dioxygenase, resulting in chlorosis and wilting of the affected weeds. When isoxaflutole is applied or after it is applied, the active ingredients retained in the surface soil due to poor soil moisture cannot play the role of weed control in time, but it can still be kept for a ...
