Problems solved by technology

However, the development cost of new active ingredients is high, the development cycle is long, and the speed of pest resistance can never be compared
Other methods, such as crop layout adjustment, rotation of different pesticides, etc., are difficult to achieve obvious effects in actual operation.

Embodiment 1

[0041] 15% Zhongbuwei · Flubendiamide EC

[0042] Add 10kg of butylcarb, 5kg of flubendiamide, 12kg of methanol, and 51kg of benzene together into the reaction kettle. After mixing and stirring, add 5kg of phenylethylphenol polyoxyethylene ether, 7kg of calcium dodecylbenzenesulfonate, and 10kg Azone was mixed and stirred evenly for 2 hours to obtain an emulsifiable concentrate preparation. This proportion is diluted and sprayed by 1000 times, and is used for preventing and treating cruciferous vegetable diamondback moth, and the control effect is 99% after 72 hours of medicine; When used after dilution of 750 times and 3500 times, the control effect is 84% ​​and 90% respectively within 72 hours after treatment.

Embodiment 2

[0044] 10.5% Zhongdingwei · Flubendiamide EC

[0045] 10kg of butylcarb, 0.5kg of flubendiamide, 12kg of methanol, and 65.5kg of toluene were added to the reaction kettle together. After mixing and stirring, 5kg of alkylphenol polyoxyethylene ether and 7kg of calcium dodecylbenzenesulfonate were added. Mix and stir evenly for 2 hours to prepare an emulsifiable concentrate preparation. The proportion is diluted and sprayed by 1000 times to prevent and control rice planthopper, and the control effect is 97% 72 hours after the drug; 25% Zhongbucarb EC and 20% flubendiamide water dispersion are diluted 750 times and 3500 times respectively according to the same method. Doubling after use, the control effects were 84% and 90% respectively within 72 hours after taking the medicine.

Embodiment 3

[0047] 12.2% Zhongbuwei · Flubendiamide EC

[0048] Add 12kg of butylcarb, 0.2kg of flubendiamide, 12kg of methanol, and 68.8kg of xylene into the reaction kettle together. After mixing and stirring, add 5kg of phenethylphenol polyoxyethylene ether and 7kg of sodium alkyl ethyl sulfonate , mixed and stirred evenly for 2 hours to obtain an emulsifiable concentrate preparation. The proportion is diluted and sprayed by 1000 times for the prevention and treatment of rice thrips, and the control effect is 92% 72 hours after the application; 25% Zhongbucarb emulsifiable concentrate and 20% flubendiamide water dispersion are diluted 750 times respectively in the same way and 3500 times later, the control effects were 84% and 90% respectively in 72 hours after the drug.

Abstract

The invention discloses a pesticide composition containing fenobucarb and flubendiamide. The weight ratio of fenobucarb to flubendiamide is (1-60):(1-10), wherein the weight percentage of fenobucarb is 1 to 60 percent, and the weight percentage of flubendiamide is 1 to 10 percent; and the pesticide composition can be prepared into missible oil or microemulsion, suspension, water emulsion, wettable powder, granules, and water dispersible granules. The invention has the advantages that: after fenobucarb and flubendiamide are combined, the pesticide composition has obvious synergistic and continuous preventing and controlling effects, the pesticidal spectrum is broadened; and the pesticide composition has high activities for rice planthopper, rice thrip, rice leafhopper, tryporyza incertulas (walker), chilo suppressalis, cnaphalocrocis medinalis guenee and plutella xylostella in cruciferous vegetables.

Description

technical field [0001] The invention relates to a composition containing effective insecticidal active ingredients secbutacarb and flubendiamide and a preparation method. Background technique [0002] Zhongdingwei, English common name Fewobucarb, chemical name 2-isopropylphenyl-N-methylcarbamate, its chemical structure is as follows: [0003] [0004] Zhongbucarb is a carbamate insecticide, which can be used to control various pests and nematodes such as rice leafhopper, rice thrips, rice leafhopper, rice stem borer, etc. The insecticidal mechanism mainly inhibits acetylcholinesterase to block normal nerve Conduction causes the imbalance of the entire physiological and biochemical process, poisons and kills the pests, and kills the insects quickly, but the residual effect is short and can only last for 4 to 5 days. Carbamates are combined with cholinesterase by the compound molecule as a whole, and the inhibitory effect is reduced after hydrolysis, so the toxicity is low...
