Problems solved by technology

[0012] The phytotoxicity and weed resistance of paddy field herbicides have always been problems in the current use process. Different herbicides have different control effects on different weeds. There are many types of weeds in crop fields. If you want to control them well It is more difficult, and at the same time, a single drug will also lead to changes in the grass phase in the field. How to develop high-efficiency compositions for grass phase changes is the future direction. Good efficacy, broad control spectrum, and slow resistance are development needs.

Embodiment 1

[0029] 3% Ebisulfone·Metuzone Microemulsion

[0030] The raw material composition is 2% tembotrione technical, 1% mefentrazone technical, 5% N, N-dimethylformamide, 10% cyclohexanone, 10% toluene, 5% phenethylphenol formaldehyde resin Polyoxyethylene ether, 3% calcium dodecylbenzene sulfonate, 7% alkylphenol polyoxyethylene ether, 5% ethylene glycol, the rest is made up with water, and is prepared in a conventional microemulsion manner.

[0031] Field Trial 1:

[0032] The experimental medicament is 3% tembotrione · fenflumezone microemulsion prepared according to Example 1, and the control medicament is 30% tembotrione suspension concentrate, 10% fenflumezone wettable powder; the control object is paddy field sedge; The effective data is shown in the table below:

[0033]

[0034] The average temperature during medication is 20-25°C, and the weather is mainly sunny to cloudy. The synergistic effect of compounding tembotrione and mefentrazone is obvious.

Embodiment 2

[0036] 6% Cyclotrione·Saflufenacil EC

[0037] Composition of raw materials: 3% tembotrione technical, 3% saflufenacil technical, 8% N, N-dimethylformamide, 10% acetone, 4% calcium dodecylbenzenesulfonate, 5% tri Phenylphenol polyoxyethylene ether, 3% phenethylphenol formaldehyde resin polyoxyethylene ether, the rest is made up with toluene. Formulated as conventional cream.

[0038] Field Trial 1:

[0039] The experimental medicament was 6% tembotrione·saflufenacil EC prepared according to Example 2, and the control agent was 10% tembotrione suspension concentrate and 5% saflufenacil EC; The effective data is shown in the table below:

[0040]

[0041] The average temperature during the medication is 20-25°C, and the weather is mainly sunny to cloudy. The synergistic effect of compounding tembotrione and saflufenacil is obvious.

Embodiment 3

[0043] 10% tembotrione · cyhalofop-emulsion in water

[0044] Composition of raw materials: 8% tembotrione, 2% cyhalofop, 5% acetone, 15% xylene, 2% calcium dodecylbenzenesulfonate, 3% tristyrylphenol polyoxyethylene Ether, 2% phenethylphenol formaldehyde resin polyoxyethylene ether, 8% anyylphenol polyoxyethylene ether, 5% ethylene glycol, and make up the rest with water. Formulated with conventional water and milk.

[0045] Field Trial 1:

[0046] The experimental medicament is 10% tembotrione · cyhalofop-methyl water emulsion prepared according to Example 3, and the control medicament is 10% tembotrione suspension concentrate and 10% cyhalofop-methyl EC; The effective data is shown in the table below:

[0047]

[0048] The average temperature is 20-25°C when the drug is used, and the weather is mainly sunny to cloudy. The synergistic effect of compounding tembotrione and cyhalofop-ethyl is obvious.

Abstract

The invention belongs to the technical field of pesticides, and relates to a tembotrions and herbicide-A-containing weeding composition. The weeding composition contains tembotrions and herbicide-A according to the weight ratio of 30:1-1:30; the total weight percentage of active components is 3 to 90 percent, and the balance contains pesticidally available and acceptable auxiliary components; after tembotrions and the herbicide-A are mixed according to a certain ratio, an obvious synergistic effect is achieved; the weeding composition can be either applied to preventing and treating barnyard grasses in a paddy field, or used for preventing and removing other gramineous weeds and dicotyledon weeds, such as monochoria vaginalis, cress, crab grasses and green bristlegrasses.

Description

Technical field: [0001] The invention belongs to the application field of pesticide and herbicide, and relates to the application of the ratio of a synergistic herbicide composition in agriculture. Background technique: [0002] Tembotrione is a triketone herbicide developed by Bayer in 2007. Its activity is higher than that of mesotrione (mesotrione, mesotrione), and it is safe for crops. [0003] The product name is: Laudis, [0004] The IUPAC names are: [0005] 2-{2-chloro-4-mesyl-3-[(2,2,2-trifluoroethoxy)methyl]benzoyl}cyclohexane-1,3-dioneCASNo:335104-84-2 [0006] Molecular weight: 468.83 [0007] Molecular formula: C 17 h 16 CIF 3 o 6 S [0008] Structural formula: [0009] [0010] The original drug of tembotrione is a beige powder with no special smell. The pure product is solid or powder at room temperature, with a melting point of 123°C, a decomposition point of about 150°C, and a relative density of D 20 is 1.56g / mL, and the vapor pressure at 25°C ...
