Embodiment 1
[0040] Example 1: 40.5% diflufenamide pendimethalin WP
[0041] Flufenamid 0.5%, pendimethalin 40%, lignosulfonate dispersant 4%, naphthalene sulfonate dispersant 2%, polyoxyethylene sulfate salt wetting agent 2%, White carbon black 3%, kaolin make up.
[0042] Mix the above-mentioned materials uniformly in proportion, and then pulverize them with a jet mill until the particle size is less than 10 μm, so as to obtain 40.5% flumefenamide pendimethalin WP.
Embodiment 2
[0043] Example 2: 1% diflufenamide pendimethalin WP
[0045] Mix the above materials uniformly in proportion, and then pulverize them with a jet mill until the particle size is less than 10 μm, so as to obtain 1% flumefenamide pendimethalin WP.
Embodiment 3
[0046] Example 3: 41% diflufenamid pendimethalin WP
[0048] Mix the above-mentioned materials uniformly in proportion, and then pulverize them with a jet mill until the particle size is less than 10 μm, so as to obtain 41% flumetrachlor pendimethalin WP.

Abstract
The present invention relates to a corn field herbicide composition. The effective components of the herbicide composition are flufenacet and pendimethalin binary complex formulation, and the mass ratio of flufenacet to pendimethalin is 1: 80-80: 1. The mass percentage of the flufenacet and the pendimethalin in the herbicide composition is 1%-80%. According to the herbicide composition, the diflufenican and the pendimethalin serve as effective components and are prepared into any dosage form together with auxiliary agents allowed in pesticide. The dosage forms are wettable powder and water dispersible granules. After the flufenacet and the pendimethalin are compounded, the weed control spectrum is expanded, the weeding effect is remarkably improved, the pendimethalin is singly used for weeding, the control effect on gramineous weeds is superior to that of broadleaf weeds, and the control effect on perennial weeds is poor; after compounding, the weeding spectrum is expanded to most perennial gramineous weeds, and after compounding, the dosage is reduced and the safety to corn is higher.
Description
technical field [0001] The invention relates to the field of pesticide preparations, in particular to a cornfield herbicide composition. Background technique [0002] Pendimethalin (Dimethalin, Pendimethalin), belongs to aniline herbicides, pure product is orange crystalline solid, melting point 54-58 ℃, solubility 25 ℃, water 0.275mg / L, easily soluble in acetone and methanol , xylene and other organic solvents, is a selective soil sealing herbicide widely used in cotton, corn, rice, potato, soybean, peanut, tobacco and vegetable fields. [0003] Flupyramid belongs to the herbicide of pyridine amide structure compound, which can inhibit the synthesis of carotenoids, and through the activity of phytoene desaturase in weeds, the chlorophyll of weed plant cells is destroyed and the cells are ruptured. It can eventually lead to albinism and death of the target weed. It has a good inhibitory and control effect on perennial grass weeds, broad-leaved weeds (including lala vine, w...
