Embodiment 1

[0023] Example 1: 1.3% bispyribac-methsulfuron-methyl oil suspension concentrate

[0024] The components of the pesticide composition containing bispyribac-methyl and metsulfuron-methyl are: 1% bispyribac-methyl, 0.3% metsulfuron-methyl, 5% phenethylphenol polyoxyethylene ether, 8% sodium lignosulfonate, cyclic Oxygenated soybean oil 5%, organic bentonite 5%, methyl oleate to 100%.

[0025] After the metsulfuron-methyl and the filler are adsorbed and mixed, the other above-mentioned materials (except organic bentonite) are added to the reactor mixer together, stirred evenly, and the materials are injected into a multi-stage sand mill for grinding. The fineness of the ground materials is 98 % After passing through 1-5um, the material is discharged, and the material is put into a high-shear emulsification kettle together with the pre-dissolved organic bentonite. After emulsification, 1.3% bispyribac-methylsulfuron oil suspension concentrate can be made.

Embodiment 2

[0026] Example 2: 2.6% bispyribac-methsulfuron-methyl suspension concentrate

[0027] The components of the pesticide composition containing bispyribac-methyl and metsulfuron-methyl are as follows: 2% bispyribac-methyl, 0.6% metsulfuron-methyl, 5% phenethylphenol polyoxyethylene ether, 8% sodium lignosulfonate, ethyl Glycol 5%, magnesium aluminum silicate 2%, defoamer 0.5%, preservative 0.1%, xanthan gum 0.1%, water to 100%.

[0028] After the metsulfuron-methyl and the filler are adsorbed and mixed, the other above-mentioned materials (except xanthan gum) are added to the reactor mixer together, stirred evenly, and the materials are injected into a multi-stage sand mill for grinding. The fineness of the ground materials is After 98% pass through 1-5um, the material is discharged, and the material is put into a high-shear emulsification kettle together with the pre-dissolved xanthan gum. After emulsification, 2.6% bispyribac-methylsulfuron-methyl suspending agent can be made. ...

Embodiment 3

[0029] Example 3: 4.9% bispyribac-methylsulfuron wettable powder

[0030] The components of the pesticide composition containing bispyribac-methyl and metsulfuron-methyl are as follows: 4% bispyribac-methyl, 0.9% metsulfuron-methyl, 2% sodium lauryl sulfate, 3% sodium butylnaphthalenesulfonate, lignin Calcium sulfonate 5%, white carbon black 5%, kaolin to 100%.

[0031] After adsorption and mixing of metsulfuron-methyl and filler, put it into the conical mixer together with other above-mentioned materials and mix evenly, and then pulverize through the jet mill, and then mix the pulverized material through the conical mixer, and the fineness of the mixed material is 98 % Pass through a 325-mesh standard sieve to obtain 4.9% bisbibclofen·methsulfuron-methyl wettable powder.

Abstract

The invention discloses a pesticide composition containing bispyribac sodium and metsulfuron methyl and application thereof. The pesticide composition comprises the following active components: bispyribac sodium and metsulfuron methyl which are in a mass ratio of 1-10: 0.1-1.5. The pesticide composition exerts an obvious synergistic effect on prevention and treatment of alternanther philoxeroides in the range of the above-mentioned ratio, so the application dosage of pesticide is reduced, pesticide application frequency is reduced, pesticide application cost is lowered down, and negative influence of the pesticide on the ecological environment is mitigated. Combination of the two active components enables spreading and regeneration capability of alternanther philoxeroides to be effectively controlled and defects and limitations in usage of a single active component to be compensated. The service life of the composition is prolonged, which is of great significance to comprehensive control of alternanther philoxeroides. Through combination of the two active components, drug effects are rapidly performed, action time of the composition is long, usage cost of the composition is low, and the composition can be used for preventing and treating alternanther philoxeroides.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pesticide composition containing bispyriben and metsulfuron-methyl, which is used for preventing and controlling Asteroides japonicus. Background technique [0002] Once it is introduced into suitable growing areas lacking effective natural enemies, it will expand and spread extremely fast, and it can invade the surrounding waters and wetlands in a short period of time, forming a large area of ​​single plant communities, and seriously damaging the local ecological environment. Biodiversity, triggering ecological disaster. In our country, Alpinia sinensis has invaded river courses, ponds, fish ponds, lakes, and farmland, seriously affecting shipping, irrigation, aquaculture, agricultural production, and the ecological environment. At present, methods such as artificial or mechanical fishing and spraying herbicides are mostly used for the control of A. Manual or ...
