Embodiment 1

[0014] Example 1: 10% Paecilomyces imidacloprid suspension (diluted 1000 times)

[0015] Part A is a 20% Paecilomyces fumigatus conidia suspension: 20% Paecilomyces fumigatus conidia powder is dissolved in a mixture of 0.21M phosphate buffer and 10% glycerol, pH 7.0, Store at 4~8℃.

[0016] Part B is wettable powder: 10% WP imidacloprid (commercially available) 3.0%, Tween-8020%, sodium lignosulfonate 6%, dispersant NNO 4%, and clay to make up to 100%.

[0017] Part A and Part B each account for 50%. The two parts are directly mixed to obtain a 10% Paecilomyces fumigatus imidacloprid suspension. The mass ratio of Paecilomyces roseus: imidacloprid is 100:15. The virulence test results are shown in Table 1.

Embodiment 2

[0018] Example 2: 5% Paecilomyces imidacloprid suspension (diluted 1000 times)

[0019] Part A is 10% Paecilomyces fumigatus conidia suspension: 10% Paecilomyces fumigatus conidia powder is dissolved in a mixture of 0.21M phosphate buffer and 10% glycerol, pH 7.0 , Store at 4~8℃.

[0020] Part B is a wettable powder: 10% WP imidacloprid 5.0%, Tween-8020%, sodium lignosulfonate 6%, dispersant NNO 4%, and clay to make up to 100%.

[0021] Part A and Part B each account for 50%, and the two parts are directly mixed to obtain 5% Paecilomyces fumigatus imidacloprid suspension, and the mass ratio of Paecilomyces fumigatus: imidacloprid is 100:50. The virulence test results are shown in Table 1.

Embodiment 3

[0022] Example 3: 50% Paecilomyces imidacloprid wettable powder

[0023] Rose smoked Paecilomyces powder (10 10 Pieces / g) 50%, 10% WP imidacloprid 3%, saponin 14%, Tween-8010%, add pottery clay to make up to 100% to prepare 50% Paecilomyces imidacloprid wettable powder. Among them, the mass ratio of Paecilomyces roseus powder: imidacloprid is 100:6. The virulence test results are shown in Table 1.

Abstract

The invention discloses a compound pesticide of Paecilomyces rosacea and imidacloprid. It consists of a main agent and an auxiliary agent. The main agent is 5-50% and the auxiliary agent is 50-95% in terms of mass percentage; the main agent is a mixture of Paecilomyces rosacea and imidacloprid. The mass ratio of imidacloprid is 100:5-50; the adjuvants are stabilizers, adjuvants and fillers. The invention discloses fungal spore wettable powder, fungal spore suspension and water dispersant prepared by using the above strains. After long-term infestation biology research and indoor bioassay, Paecilomyces rosacea has a strong infestation and insecticidal effect on a variety of pests, especially piercing-sucking pests. The compound insecticide of Paecilomyces rosacea and imidacloprid has a good control effect on pests such as whiteflies, aphids, diamondback moths and the like.

Description

Technical field [0001] The invention relates to a microbial insecticide, in particular to an environmentally friendly, pollution-free, and residue-free compound insecticide of Paecilomyces fumigatus and imidacloprid. Background technique [0002] Paecilomyces fumosoroseus (Wize) Brown et Smith is an insect pathogenic fungus. As a living biological pesticide, it has a completely new mechanism of action different from existing chemical pesticides, and has no pollution to the environment. The characteristic of non-residue, can be used as an alternative control drug for the control of certain insects that are resistant to Bacillus thuringiensis (Bt). The development and utilization of Paecilomyces fumigatus has important economic significance. Paecilomyces fumigatus has a wide distribution, has a good control effect on aphids, whitefly, diamondback moth, etc., and has good application prospects. [0003] Imidacloprid is a widely used high-efficiency, systemic, broad-spectrum nicotine...
