Embodiment 1

[0017] Embodiment 1: 10% Paecilomyces beta-cypermethrin suspension concentrate (diluted 1000 times)

[0018] Part A is 20% Paecilomyces fumigatus conidia suspension: 20% Paecilomyces fumigatus conidia powder is dissolved in 0.21M phosphate buffer and 10% glycerol mixture, pH7.0 , Store at 4-8°C.

[0019] Part B is wettable powder: 4.5% EC beta-cypermethrin (commercially available) 4.0%, Tween-80 20%, sodium lignosulfonate 6%, dispersant NNO 4%, add clay to make up to 100%.

[0020] Part A and part B each account for 50%, and the two parts are directly mixed to obtain 10% Paecilomyces fumigatus-beta-cypermethrin suspension concentrate, and the mass ratio of Paecilomyces fumigatus:beta-cypermethrin is 100:0.9. The results of the toxicity test are shown in Table 1.

Embodiment 2

[0021] Embodiment 2: 5% Paecilomyces beta-cypermethrin suspension concentrate (diluted 1000 times)

[0022] Part A is 10% Paecilomyces fumigatus conidia suspension: Dissolve 10% Paecilomyces fumigatus conidia powder in 0.21M phosphate buffer and 10% glycerol mixture, pH 7.0 , Store at 4-8°C.

[0023] Part B is wettable powder: 4.5% EC beta-cypermethrin 8.0%, Tween-80 20%, sodium lignosulfonate 6%, dispersant NNO 4%, add clay to make up to 100%.

[0024] Part A and part B each account for 50%, and the two parts are directly mixed to obtain 5% Paecilomyces fumigatus-beta-cypermethrin suspension concentrate, and the mass ratio of Paecilomyces fumigatus:beta-cypermethrin is 100:3.6. The results of the toxicity test are shown in Table 1.

Embodiment 3

[0025] Embodiment 3: 50% Paecilomyces beta-cypermethrin wettable powder

[0026] Rose smoke Paecilomyces powder (10 10 Individual / g) 50%, 4.5% EC beta-cypermethrin 4%, saponin 14%, Tween-80 10%, add potter's clay and mend to 100%, make 50% Paecilomyces beta-cypermethrin wettable powder. Wherein, the mass ratio of Paecilomyces fumigatus powder: beta-cypermethrin is 100:0.36. The results of the toxicity test are shown in Table 1.

Abstract

The invention discloses an insecticide compounded by paecilomyces fumosoroseus and Alpha-cypermethrin, which consists of a main agent and an auxiliary agent. According to the mass percentage, the main agent occupies 5-50% and the auxiliary agent occupies 50-95%; the main agent is the mixture of the paecilomyces fumosoroseus and the Alpha-cypermethrin with the mass proportion of 100:0.3-4; the auxiliary agent is stabilizer, assisting agent and filling material. The compounded insecticide of the invention can be processed into wettable powder, suspension agent or oil agent; according to long-term infection biological study and indoor biological testing, the paecilomyces fumosoroseus has extremely strong infection insecticidal effects on a plurality of pests, especially for the pests of piercing-sucking mouthpart. The compounded insecticide of the paecilomyces fumosoroseus and the Alpha-cypermethrin has excellent control effects on the pests such as diamondback moth, aphid, thrips, etc.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and specifically relates to a biological insecticide, in particular to an environmentally friendly, pollution-free, and residue-free compound insecticide of Paecilomyces fumigatus and beta-cypermethrin. Background technique [0002] Paecilomyces fumosoroseus (Wize) Brown & Smith is an entomopathogenic fungus. As a living biopesticide, it has a new mechanism of action different from existing chemical insecticides, has no pollution to the environment, and has no residues. and other characteristics, it can be used as an alternative control drug for the control of certain insects resistant to Bacillus thuringiensis (Bt), and the development and utilization of Paecilomyces fumigatus has important economic significance. Paecilomyces fumigatus is widely distributed, and has good control effects and broad application prospects on aphids, whitefly, diamondback moth, etc. [0003] Beta-cypermethrin (be...
