The invention aims to overcome the defects of the prior art, and provides a spinosad insecticidal aerosol and application thereof, which are green, environment-friendly, degradable and good in insecticidal effect.
In order to achieve the above purpose, the technical scheme adopted by the invention is as follows:
the spinosad insecticidal aerosol comprises the following raw materials in percentage:
further, the knockdown agent comprises one or more of propathrin, dextromethorphan, biological propathrin, tetrafluoroethrin, allethrin or tetramethrin;
the synergistic ether comprises piperonyl butoxide.
Further, the solvent comprises sec-butanol, tert-butanol, ethanol, dimethylpentane, nonane, dodecane, solvent oil, isoparaffin solvent oil.
Further, the solvent oil adopts one or two of D60 solvent oil and D80 solvent oil;
the isoparaffin solvent oil adopts isoparaffin solvent oil with the distillation range of 249-267 ℃ or isoparaffin solvent oil with the distillation range of 186-20 ℃.
Further, the stabilizer comprises one or more of BHT or BHA.
Further, the propellant comprises propane, compressed air or dimethyl ether.
Further, the lemon essential oil comprises 0.01-0.05% of lemon essential oil.
Further, the mass ratio of the spinosad to the lemon essential oil is 20-30:1.
The spinosad insecticidal aerosol is applied to killing mosquitoes, flies and cockroaches.
Compared with the prior art, the invention has the following beneficial effects:
the spinosad is taken as an effective medicinal component, has the quick action of chemical pesticides and the safety of biological pesticides, has high activity on mosquitoes and flies, has short degradation half-life in a low-dose spraying environment, is safe to mammals, birds and fishes, is an insecticidal aerosol product with higher safety, and in addition, the spinosad and the lemon essential oil are compounded, and the insecticidal activity of the spinosad is greatly improved by utilizing the synergistic effect of the spinosad and the lemon essential oil.
