Embodiment 1

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

[0016] Part A is 40% Paecilomyces fumigatus conidia suspension: 40% Paecilomyces fumigatus conidia powder is dissolved in a mixture of 0.21M phosphate buffer and 10% glycerol, pH 7.0 , and stored at 4-8°C.

[0017] Part B is wettable powder: acetamiprid (commercially available) 4%, Tween-8020%, sodium lignosulfonate 6%, wetting agent LX 4%, and clay to make up to 100%.

[0018] Part A and part B each account for 50%, and the two parts are directly mixed to obtain 20% Paecilomyces acetamiprid suspension, and the mass ratio of Paecilomyces rosacea:acetamiprid is 100:10. The virulence test results are shown in Table 1.

Embodiment 2

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

[0020] Rose Smoke Paecilomyces Powder (10 10 pcs / g) 50%, acetamiprid 2% (commercially available), Tween-805%, paraffin oil 23%, methyl green 2%, add diatomaceous earth to make up to 100%, to obtain 50% Paecilomyces Acetamiprid oil. Wherein, the mass ratio of Paecilomyces rosacea powder:acetamiprid is 100:4. The virulence test results 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 pcs / g) 60%, acetamiprid 1% (commercially available), methyl green 2%, Tween-8010%, sodium lignosulfonate 3%, wetting agent LX 2%, kaolin to make up to 100%, A 60% rose-smoked Paecilomyces acetamiprid wettable powder was prepared. Wherein, the mass ratio of Paecilomyces roseus powder:acetamiprid is 100:1.67. The virulence test results 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, additionagent 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, in particular to a microbial pesticide, in particular to an environmentally friendly, pollution-free and residue-free compound pesticide of Paecilomyces rosacea 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 that is different from existing chemical pesticides, and has no pollution to the environment and no residue. It can be used as an alternative control drug for controlling some insects that are resistant to Bacillus thuringiensis (Bt). The development and utilization of Paecilomyces fumigatus has important economic significance. Paecilomyces rosacea is widely distributed, has a good control effect on aphids, Bemisia tabaci, diamondback moth, etc., and has a good application prospect. [0003] Acetamiprid (acetamiprid) is a new type of nicotinic inse...
