Problems solved by technology

[0004] At present, the main means of prevention and control of such pests in my country is mainly chemical pesticide control, but with the continuous increase and innovation of the types of insecticides, due to the lack of understanding of insecticides and unreasonable mix and match, people began to abuse them in large quantities. Insecticides, which not only fail to achieve good economic benefits, but also cause environmental pollution and increase the resistance of pests, and some even seriously harm their natural enemies

Embodiment 1

[0026] The pesticide preparation 100kg that is used for preventing and treating Drosophila spotted wing described in the present embodiment, by weight percentage, its raw material is composed of: bifenthrin former medicine 2%, azadirachtin former medicine 5%, transdermalin 4%, pesticide Emulsifier 22015%, N,N-dimethylformamide solvent balance.

[0027] The preparation method of the pesticide preparation described in this example is: add part of the solvent to bifenthrin, stir for 30-60 minutes, then add the emulsifier 2201 to it while stirring; Then add azadirachtin, stir until the azadirachtin dissolves, then add transdermal, add the remaining amount of solvent, and stir to obtain a uniform and transparent solution that is the target pesticide preparation.

[0028] The pesticide preparation prepared above was used for the control of Drosophila spotted wing by referring to the improved Petri dish coating method of NY / T1154.8-2007 filter paper coating method, and the mortality ...

Embodiment 2

[0030] The pesticide preparation 100kg that is used for preventing and treating Drosophila spotted wing described in the present embodiment, by weight percentage, its raw material consists of: bifenthrin former medicine 4%, azadirachtin former medicine 10%, transdermalin 6%, pesticide Emulsifier 220110%, N, N-dimethylformamide solvent balance.

[0031] The preparation method of the pesticide formulation described in this example is the same as that in Example 1.

[0032] The pesticide preparation prepared above was used for the control of Drosophila spotted wing by referring to the improved Petri dish coating method of NY / T1154.8-2007 filter paper coating method, and the mortality rate of Drosophila spotted wing reached 93.12%.

Embodiment 3

[0034] The pesticide preparation 100kg that is used for preventing and treating Drosophila spotted wing described in the present embodiment, by weight percentage, its raw material is made up of: the former medicine of bifenthrin 8%, the former medicine of azadirachtin 12%, transdermal 5%, pesticide Emulsifier 220115%, N, N-dimethylformamide solvent balance.

[0035] The preparation method of the pesticide formulation described in this example is the same as that in Example 1.

[0036] The pesticide preparation prepared above was used for the control of Drosophila spotted wing by referring to the improved Petri dish coating method of NY / T1154.8-2007 filter paper coating method, and the mortality rate of Drosophila spotted wing reached 94.75%.

Abstract

The invention belongs to the technical field of pesticide preparations, particularly relates to a pesticide composition used for preventing and controlling Drosophila suzukii, and further discloses a preparation method of the pesticide composition.The pesticide composition is formed by compounding bifenthrin and azadirachtin which are used as raw material pesticide, the advantages of the two types of pesticide are brought into full play and supplement each other, the advantages that azadirachtin is short in residue longevity and bifenthrin is rapid in effect are brought into play, the disadvantage that bifenthrin does not have systemic translocation is overcome, and the unexpected synergism is achieved after the two types of pesticide are compounded for use compared with the effects achieved when the raw material pesticide is independently used.The Drosophila suzukii prevention and control effect of the pesticide composition is remarkable, the number of pesticide spraying times is decreased, resistance is delayed, the service life of the new species is prolonged, the effects of reducing cost and environment pollution are achieved, the prevention and control effect of the compound pesticide composition is good, the prevention and control effect on Drosophila suzukii can reach 97% or above, and cost and environment pollution are reduced.

Description

technical field [0001] The invention belongs to the technical field of pesticide preparations, in particular relates to a pesticide composition for preventing and treating spotted winged fruit flies, and further discloses a preparation method thereof. Background technique [0002] Drosophilasuzukii, also known as Cherry Drosophila and Drosophila Suzuki, belongs to the order Diptera, the suborder Annuli, the family Drosophilidae, the genus Drosophila, and the subgenus Drosophila. Drosophila spotted wing is a common pest faced by many orchard crops. Drosophila spotted wing is harmful to the planting of various berries and stone fruits such as blueberries, blackberries, cherries, strawberries, plums, peaches, grapes, figs, kiwis and pears. have greater hazards. [0003] Drosophila spotted wing first appeared in Japan and China, and has recently invaded other countries. Because the ovipositor of Drosophila spotted wing is jagged and has a certain hardness, it can easily pierce ...
