Embodiment 1

[0022] Embodiment 1: 20% Verticillium lecanii acetamiprid suspension concentrate (diluted 2000 times during use)

[0023] Part A is 40% conidia suspension of Verticillium lecanii: 40% conidia powder of Verticillium lecanii is dissolved in 0.21M phosphate buffer and 10% glycerol mixture, adjust pH 7.0, in Store at 4-8°C.

[0024] Part B is wettable powder: acetamiprid (commercially available) 4%, Tween-80 20%, sodium lignosulfonate 6%, wetting agent LX 4%, add clay to make up to 100%.

[0025] Part A and Part B each account for 50%, and the two parts are directly mixed to obtain 20% Verticillium lecanii acetamiprid suspension concentrate, and the mass ratio of Verticillium lecanii:Acetamiprid is 100:10. The results of the toxicity test are shown in Table 1.

Embodiment 2

[0026] Embodiment 2: 50% Verticillium lecanii acetamiprid oil (diluted 2000 times during use)

[0027] Verticillium lecanii powder (10 10 each / g) 50%, acetamiprid 2% (commercially available), Tween-80 5%, paraffin oil 23%, methyl green 2%, add diatomaceous earth and mend to 100%, make 50% imitation green Myacetamiprid oil. Wherein, the mass ratio of Verticillium lecanii bacterial powder: acetamiprid is 100:4. The results of the toxicity test are shown in Table 1.

Embodiment 3

[0028] Embodiment 3: 60% Verticillium lecanii acetamiprid wettable powder (diluted 2000 times during use)

[0029] Verticillium lecanii powder (10 10 unit / g) 60%, acetamiprid 1% (commercially available), methyl green 2%, Tween-80 10%, sodium lignosulfonate 3%, wetting agent LX 2%, kaolin supplemented to 100% , to prepare 60% Verticillium lecanii acetamiprid wettable powder. Among them, the mass ratio of Verticillium lecanii bacteria powder: acetamiprid is 100:1.67. The results of the toxicity test are shown in Table 1.

Abstract

The present invention discloses an insect disinfestation main agent compounded by verticillum lecanii and acetamiprid and an insecticide thereof. The main agent is the mixture of verticillum lecanii and acetamiprid. The mass ratio between verticillum lecanii and acetamiprid is 100: 1.5-12. The insecticide is composed of the main agent and assistant agent. According to the weight percentage, the main agent is 22-61%, and the assistant agent is 39%-78%. After long-time infection biology research and indoor biological assay, the verticillum lecanii has strong infection insect killing effect to a plurality of insects, especially the piercing-sucking mouthparts insects. The insecticide compounded by verticillum lecanii and acetamiprid has excellent control efficiency to insects of whitefly, aphids, diamondback moth, etc.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and specifically relates to a microbial insecticide, in particular to an environmentally friendly, pollution-free, and residue-free insecticide main agent and insecticide compounded by Verticillium lecanii and acetamiprid. Background technique [0002] Verticillium lecanii (Zimmermann) Viegas is an entomopathogenic fungus. As a living biopesticide, it has a new mechanism of action different from existing chemical insecticides, and has the characteristics of no pollution to the environment and no residue. , can be used as an alternative control drug to control some insects resistant to Bacillus thuringiensis (Bt), and the development and utilization of Verticillium lecanii has important economic significance. Verticillium lecanii is widely distributed, and has good control effects on whitefly, greenhouse whitefly, aphids, thrips, etc., and has broad application prospects. [0003] Acetamiprid ...
