Embodiment 1

[0022] Example 1: 20% Verticillium lecanii acetamiprid suspension (diluted 2000 times when used)

[0023] Part A is a 40% Verticillium lecanii conidia suspension: 40% Verticillium lecanii conidia powder is dissolved in a mixture of 0.21M phosphate buffer and 10% glycerol, and the pH is adjusted to 7.0. Store at 4~8℃.

[0024] Part B is a 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 a 20% Verticillium lecanii acetamiprid suspension. The mass ratio of Verticillium lecanii: Acetamiprid is 100:10. The virulence test results are shown in Table 1.

Embodiment 2

[0026] Example 2: 50% Verticillium lecanii Acetamiprid oil (diluted 2000 times when used)

[0027] Verticillium lecanii powder (10 10 Pieces / g) 50%, Acetamiprid 2% (commercially available), Tween-805%, Paraffin oil 23%, Methyl green 2%, add diatomaceous earth to make up to 100%, to make 50% Paecilomyces Acetamiprid oil agent. Among them, the mass ratio of Verticillium lecanii powder: Acetamiprid is 100:4. The virulence test results are shown in Table 1.

Embodiment 3

[0028] Example 3: 60% Verticillium lecanii acetamiprid wettable powder (diluted 2000 times when used)

[0029] Verticillium lecanii powder (10 10 Pieces / g) 60%, Acetamiprid 1% (commercially available), Methyl Green 2%, Tween-8010%, Sodium Lignosulfonate 3%, Wetting Agent LX 2%, Kaolin Supplement to 100%, A 60% wettable powder of Verticillium lecanii Acetamiprid was prepared. Among them, the mass ratio of Verticillium lecanii powder: Acetamiprid is 100:1.67. The virulence test results 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 aplurality 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 main insecticide and insecticide composed of Verticillium lecanii and acetamiprid. Background technique [0002] Verticillium lecanii (Zimmermann) Viegas is an insect pathogenic 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. , It can be used as an alternative medicine to control certain insects that are resistant to Bacillus thuringiensis (Bt). The development and utilization of Verticillium lecanii is of great economic significance. Verticillium lecanii has a wide distribution and has a good control effect on whitefly, whitefly, aphids, thrips, etc., and has broad application prospects. [0003] Acetamiprid (ace...
