Embodiment 1
[0021] Embodiment 1: 20% Verticillium leek avermectin suspension (diluted 2000 times during use)
[0022] Part A is 40% Verticillium cereus conidia suspension: 40% Verticillium cereus conidia powder was dissolved in a mixture of 0.21M phosphate buffer and 10% glycerol, pH 7.0, at 4 Store at ~8°C.
[0023] Part B is wettable powder: 1.8% abamectin (commercially available) 12%, Tween-80 20%, sodium lignosulfonate 6%, wetting agent LX 4%, and clay to make up to 100%.
[0024] The A part and the B part each account for 50%, and the two parts are directly mixed to obtain 20% of the Verticillium cereus avermectin suspension. The virulence test results are shown in Table 1.
Embodiment 2
[0025] Example 2: 50% Verticillium leek avermectin oil (diluted 2000 times during use)
[0026] Verticillium cereus powder (10 10 pcs / g) 50%, 1.8% abamectin 10% (commercially available), Tween-80 5%, paraffin oil 23%, methyl green 2%, add diatomaceous earth to make up to 100%, to prepare 50 % Verticillium cereus avermectin oil. Wherein, the mass ratio of Verticillium cereus powder: avermectin is 100:0.36. The virulence test results are shown in Table 1.
Embodiment 3
[0027] Example 3: 60% Verticillium leek avermectin oil (diluted 2000 times during use)
[0028] Verticillium cereus powder (10 10 pcs / g) 60%, 1.8% abamectin 5% (commercially available), methyl green 2%, Tween-80 5%, paraffin oil 23%, kaolin to make up to 100%, to obtain 60% Lexus Verticillium avermectin oil. Wherein, the mass ratio of Verticillium cereus powder: avermectin is 100:0.15. The virulence test results are shown in Table 1.

Abstract
The invention discloses a compound desinsection primary agent and a pesticide consisting of verticillium lecanii and abamectin. The primary agent is a mixture of the verticillium lecanii and the abamectin, wherein, the mass ratio between the verticillium lecanii and the abamectin is 100:0.1-0.5; through long-term infection biological study and interior biological assay, the verticillium lecanii has strong infection desinsection effect on a plurality of pests, the sucking pest in particular. The compound pesticide consisting of verticillium lecanii and abamectin of the invention has good effect in preventing and controlling pests such as trialeurodes vaporariorum westwood, bemisa babaci, plant louse, diamond back moth, thrips palmi karny and the like, and has certain effect in controlling mite pests.
Description
technical field [0001] The invention belongs to the technical field of pesticides, in particular to a microbial pesticide, in particular to an environmentally friendly, non-polluting, non-residue insecticidal main agent and pesticide compounded by Verticillium cereus and avermectin . Background technique [0002] Verticillium lecanii (Zimmermann) Viegas is an entomopathogenic fungus. As a living biological pesticide, it has a new mechanism of action that is different from existing chemical pesticides, and has the characteristics of no pollution to the environment and no residue. As an alternative control drug for controlling some insects resistant to Bacillus thuringiensis (Bt), it is of great economical significance to develop and utilize Verticillium leek. Verticillium leek is widely distributed, has good control effect on Bemisia tabaci, greenhouse whitefly, aphids, thrips, etc., and has broad application prospects. [0003] Abamectins is a nerve agent that acts on inse...
