Embodiment 1
[0039] Example 1 15% spinosad deltamethrin dispersible oil suspension
[0040] The formula is: active ingredient spinosad 10%, deltamethrin 5%, emulsifier polyoxyethylene ether carboxylate 3%, sorbitan monolaurate 2%, dispersant polyoxyethylene-polyethylene Oxypropylene block copolymer 3%, sodium alkylphenol sulfonate 3%, wetting agent alkyl sulfonate 1%, sodium lauryl sulfate 3%, thickener polyvinyl alcohol 2.5%, magnesium silicate Aluminum 2.5%, stabilizer butyl hydroxyanisole 2%, the balance is epoxy soybean oil.
[0041] Preparation method: add emulsifier, dispersant, wetting agent and stabilizer to the dispersion medium, add them into the reaction kettle with shearing device, fully mix emulsification, and disperse evenly; under high-speed shear state (2000- 10000r / min) and then add thickener, ethyl spinosad and deltamethrin into the reaction kettle, cut for 15-30 minutes, then grind under the zirconium bead sanding medium, grind for 2-3h, use laser Particle size distrib...
Embodiment 2
[0042] Example 2 20% spinosad deltamethrin dispersible oil suspension
[0043] The formula is: active ingredient spinosad 10%, deltamethrin 10%, emulsifier styrylphenol polyoxyethylene ether 12%, calcium dodecylbenzenesulfonate 3%, dispersant lignosulfonic acid Calcium 3%, sodium polycarboxylate 1%, wetting agent fatty alcohol polyoxyethylene ether sodium sulfate 2%, sodium lauryl sulfate 6%, thickener white carbon black 0.5%, organic bentonite 2%, stable Agent epichlorohydrin 2%, the balance is methyl oleate. The preparation method is the same as in Example 1.
Embodiment 3
[0044] Example 3 30% spinosad deltamethrin dispersible oil suspension
[0045] The formula is: active ingredient spinosad 20%, deltamethrin 10%, emulsifier styrylphenol polyoxyethylene ether 9%, calcium dodecylbenzenesulfonate 3%, dispersant lignosulfonic acid Calcium 4%, polycarboxylate sodium salt 2%, wetting agent fatty alcohol polyoxyethylene ether sodium sulfate 3%, sodium lauryl sulfate 6%, thickener white carbon black 1%, organic bentonite 3%, stable Agent epichlorohydrin 2%, the balance is methyl oleate. The preparation method is the same as in Example 1.

Abstract
The invention discloses an insecticidal composition containing spinetoram and deltamethrin, as well as a preparation method and application thereof. The insecticidal composition is prepared from 10-35 weight percent of spinetoram and 5-15 weight percent of deltamethrin. The spinetoram and deltamethrin are combined to prepare a dispersible oil suspension, the insecticidal effect is remarkably improved, and the insecticidal composition can be widely applied to paddy, corn, sugarcane, vegetables and other crops for preventing and controlling plutella xylostella, asparagus caterpillar, prodenia litura, etiella zinckenella, chilo suppressalis walker, tryporyza incertulas, cnaphalocrocis medinalis, ostrinia nubilalis, leaf miner, thrips, aleyrodid, aphid and other insect pests. The dispersible oil suspension has good emulsifying dispersibility, thickening or bottom sticking prevention, high suspension rate and good thermal storage stability, can be used in conventional spraying and spraying by a vegetable-protecting unmanned aerial vehicle, and has the advantages of volatilization prevention, drift resistance, strong infiltration conductivity, rain wash resistance and high bioactivity for targets.
Description
technical field [0001] The present invention relates to an insecticidal composition compounded by pleocidin and deltamethrin, and also relates to a dispersible oil suspension of the insecticidal composition containing pleocidin and deltamethrin The dosage form and its preparation method and application belong to the technical field of pesticides. Background technique [0002] Spinosyn is a new spinosad insecticide produced by Dow AgroSciences, which is a biomimetic pesticide. The target is the nicotinic acetylcholine receptor. It is a high-efficiency and broad-spectrum insecticide. It is mainly used to control Lepidoptera and Thysanoptera larvae. Vegetable pests such as noctuid moth and bean pod borer have good control effects, and are widely used in the rotation of pesticide varieties for the control of resistance of vegetable pests. Due to the increase in the cost of pesticides for field crops such as rice, corn, and sugarcane, pleocidin has gradually been popularized an...
