Problems solved by technology

Although pichridam has a new mechanism of action, because it is a new neonicotinoid insecticide, there is still a risk of resistance to long-term single use
[0004] At present, the pesticide preparations with sulfoxaflor as the active ingredient are mainly 22% sulfoxaflor suspension concentrate. In actual use, the cost of use is relatively high, and there is a risk of resistance. The mixed use of pichridam with different mechanisms is expected to achieve a better control effect, which has a significant synergistic effect and can reduce the cost of use. It can delay the generation of pest resistance, be safe for crops, and play a positive role in the comprehensive management of pest resistance. the meaning of

Embodiment 1

[0070] Weigh 10% phenantrid, 10% sulfoxaflor, 3% TERSPERSE 4894, 1% TERSPERSE 2500, 2% alkylphenol polyoxyethylene ether formaldehyde condensate sulfate SOPA-270, 0.3% xanthan gum, 5% propylene glycol, 0.5% benzoic acid, 0.5% silicone defoamer s-29, and deionized water are added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sand-milled with a sand mill to prepare 20% sulfoxaflor-pichamid suspension concentrate.

[0071]The formula is used to prevent and control rice brown planthopper. The dosage per mu is 15g, diluted and sprayed with 30kg of water, and the control effect is 96.2% after 7 days of application, and 94.4% after 14 days of application. The dosage of 22% sulfoxaflor SC is 15g per mu and the dosage of 10% pichamiprid SC is 25g per mu. Using the same method, the control effects after 7 days of application are respectively 86.7% and 78.1%. The 14-day control effects were 84.5% and 82.6%, respectively. The synergis...

Embodiment 2

[0073] Weigh 20% sulfoxaflor, 10% fenpyrid, 4% TERSPERSE 4894, 1.5% TERSPERSE 2500, 2% TERSPERSE 2425, 0.2% magnesium aluminum silicate, 5% ethylene glycol, 0.5% formaldehyde, 0.5% Silicone defoamer s-29 and deionized water are added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare a 30% sulfoxaflor-pichamid suspension concentrate.

[0074] The formula is used to prevent and control rice weevil. The dosage per mu is 15g, diluted and sprayed with 30kg of water, and the control effect is 97.2% after 7 days and 95.6% after 14 days. The dosage of 22% sulfoxaflor SC is 20g per mu and the dosage of 10% chlorpyrid SC is 30g per mu. Using the same method, the control effects after 7 days of application are 87.6% and 73.4% respectively. The 14-day control effects were 84.3% and 85.2%, respectively. The synergistic effect of the compound combination of sulfoxaflor and penicillin is obvious, the contro...

Embodiment 3

[0076] Weigh 16% sulfoxaflor, 4% piperid, 2% TERSPERSE 4894, 2% Nongru 700#, 1.5% TERSPERSE 2500, 2% diffusing agent NNO, 0.2% xanthan gum, 5% propylene glycol, 0.5 % benzoic acid, 0.5% silicone defoamer s-29, and deionized water are added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sand-milled with a sand mill to prepare 20% sulfoxaflor-pichamid suspension concentrate.

[0077] The formula is used to control citrus aphids, and the dilution factor is 2500 times for spraying. The control effect is 94.3% after 3 days and 92.6% after 7 days. The 22% sulfoxaflor suspension concentrate was diluted by 2000 and the 10% piperidon suspension was diluted by 1500. Using the same method, the control effects were 87.3% and 74.4% respectively after 3 days of application. The 7-day control effects were 82.6% and 83.2% respectively. The synergistic effect of the compound combination of sulfoxaflor and penicillin is obvious, the control ...

Abstract

The invention discloses an insecticidal composite containing sulfoxaflor and paichongding (ipp), wherein the weight ratio of the sulfoxaflor to the ipp is (1:8) to (8:1). The insecticidal composite can be prepared in the form of water dispersible granules, wettable powders, suspending agents, and diversifiable oil suspending agents. The insecticidal composite is reasonable in component, good in insecticidal effect, and low in application cost; the activity and insecticidal effect of the composite are not a simple sum of the activities and insecticidal effects of the components; compared with existing single preparations, besides having a significant insecticidal effect, the insecticidal composite also has an obvious synergistic effect, can slow down the production of resistance, has less preparation residual quantity, has no pollution to crops, is good in safety, and meets the safety requirement for pesticide preparations. The insecticidal composite has a good control effect on sucking pests on the crops such as rice, vegetables, cottons, fruit trees and the like.

Description

technical field [0001] The invention relates to an insecticidal composition containing sulfoxaflor and phenantrid, belonging to the technical field of compound pesticides. Background technique [0002] The English common name of sulfoxaflor is sulfoxaflor, the chemical name is [1-[6-(trifluoromethyl)pyridin-3-yl]ethyl]methyl(oxygen)-λ4-mercaptocyanamide, and the chemical formula is C 10 h 10 f 3 N 3 OS. Sulfoxaflor is a sulfonylimide insecticide, and sulfonylimide acts on the nervous system of insects, that is, acts on a unique binding site in the choline receptor to exert its insecticidal function. It can be absorbed into plants through leaves, stems and roots. Sulfoxaflor has no cross-resistance with many other existing insecticides, and can control most of the Homopteran pests, especially the Aphididae, Whitefly, Leafhopper and Planthopper pests. It is suitable for vegetables and rice , cotton, fruit trees and a variety of field crops. However, in the actual applic...
