Embodiment 1

[0015] Embodiment 1: 20% Paecilomyces acetamiprid suspension concentrate (diluted 2000 times)

[0016] Part A is 40% Paecilomyces fumigatus conidia suspension: 40% Paecilomyces fumigatus conidia powder is dissolved in 0.21M phosphate buffer and 10% glycerin mixture, pH7.0 , Store at 4-8°C.

[0017] 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%.

[0018] Part A and part B each account for 50%, and the two parts are mixed directly to obtain 20% Paecilomyces fumosinica acetamiprid suspension concentrate. The results of the toxicity test are shown in Table 1.

Embodiment 2

[0019] Embodiment 2: 50% Paecilomyces fumigatus acetamiprid oil (diluted 2000 times)

[0020] Rose smoke Paecilomyces 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 Paecilomyces fumigatus powder: acetamiprid is 100:4. The results of the toxicity test are shown in Table 1.

Embodiment 3

[0021] Embodiment 3: 60% Paecilomyces acetamiprid wettable powder (diluted 2000 times)

[0022] Rose smoke Paecilomyces 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% Paecilomyces fumigatus acetamiprid wettable powder. Wherein, the mass ratio of Paecilomyces fumigatus powder: acetamiprid is 100:1.67. The results of the toxicity test are shown in Table 1.

Abstract

The invention discloses a combination pesticide of paecilomyces fumosoroseus and acetamiprid, comprising 22 to 61 percent of host crystal and 39 to 78 percent of adjuvant according to mass percent, the host crystal is the mixture of paecilomyces fumosoroseus and acetamiprid, the mass ratio of the paecilomyces fumosoroseus and the acetamiprid is 100: 1.5 to 10; the adjuvant is stabilizer, addition agent and filler. The invention discloses wettable powder of fungal spore, suspending agent of fungal spore and medicinal oil made by using the bacterial strain. By adopting the blending of agricultural chemical and biopesticide with sub-dose, the combination pesticide of the invention can improve the quick-acting property of microbial pesticide and reduce the residual amount of agricultural chemical, meets the production demands of organic foods, has no pollution and residue to environment and is beneficial to deferring the generation of drug fastness of pests, especially has good control effects on pests such as whitefly and aphis and 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 compound insecticide of Paecilomyces fumigatus and acetamiprid. Background technique [0002] Paecilomyces fumosoroseus (Wize) Brown & Smith is an entomopathogenic fungus. As a living biological pesticide, it has a new mechanism of action different from existing chemical insecticides, and is environmentally friendly and non-toxic. The residual characteristics can be used as an alternative control drug for the control of some insects resistant to Bacillus thuringiensis (Bt), and the development and utilization of Paecilomyces fumosorose has important economic significance. Paecilomyces fumigatus is widely distributed, and has good control effects on aphids, whitefly, diamondback moth, etc., and has a good application prospect. [0003] Acetamiprid (acetamiprid) is...
