Embodiment 1

[0017] Embodiment 1: 20% Paecilomyces javanica abamectin suspension concentrate (diluted 2000 times)

[0018] Part A is 40% Paecilomyces Javanese conidia suspension: 40% Paecilomyces Javanese conidia powder is dissolved in 0.21M phosphate buffer and 10% glycerol mixture, pH 7.0, at 4-8 Store at ℃.

[0019] Part B is wettable powder: 1.8% abamectin (commercially available) 10%, Tween-80 20%, sodium lignosulfonate 6%, wetting agent LX 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 20% Paecilomyces abamectin suspension concentrate, and the mass ratio of Paecilomyces javanica: abamectin is 100:0.45. The results of the toxicity test are shown in Table 1.

Embodiment 2

[0021] Embodiment 2: 50% Paecilomyces javanica abamectin oil (diluted 2000 times)

[0022] Paecilomyces javanica powder (10 10 Individual / g) 50%, 1.8% Abamectin 10% (commercially available), Tween-80 5%, paraffin oil 23%, methyl green 2%, add diatomaceous earth and mend to 100%, make 50 % Paecilomyces abamectin oil. Wherein, the mass ratio of Paecilomyces javanica powder: abamectin is 100:0.36. The results of the toxicity test are shown in Table 1.

Embodiment 3

[0023] Embodiment 3: 60% Paecilomyces abamectin oil (diluted 2000 times)

[0024] Paecilomyces javanica powder (10 10 Individual / g) 60%, 1.8% abamectin 5% (commercially available), methyl green 2%, Tween-80 5%, paraffin oil 23%, kaolin supplemented to 100%, prepared 60% Javanese Penicillium avermectin oil. Wherein, the mass ratio of Paecilomyces javanica powder: abamectin is 100:0.15. The results of the toxicity test are shown in Table 1.

Abstract

The invention discloses a mixed insecticide of paecilomyces javanicus and avermectin, which consists of a main agent and an adjuvant, and is characterized in that according to the weight percent, the main agent is 20 - 60 percent, and the adjuvant is 40 - 80 percent; the main agent is the mixture of the paecilomyces javanicus and the avermectin, and the weight ratio of the paecilomyces javanicus and the avermectin is 100:0.1 - 0.5; and the adjuvant is a stabilizer, a promoter and a filler. The mixed insecticide of the invention can be processed into a wettable powder, a suspending agent or an oil agent; and by long-term infection biology researches and indoor creature tests, the mixed insecticide of the invention has strong infection insecticidal effect on a plurality of pests, in particular to the pests with piercing-sucking mouthparts, has good preventing effect on such pests as whitefly, cotton leafworm, diamondback moth, and the like, and has a certain control effect on mite pests at the same time.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a microbial insecticide, in particular to a compound insecticide of Paecilomyces javanica and abamectin which is environment-friendly, pollution-free and residue-free. Background technique [0002] Paecilomyces javanicus Isaria javanicus (Friendrichs & Bally) is an entomopathogenic fungus. As a living biological pesticide, it has a new mechanism of action different from existing chemical insecticides, has no pollution to the environment, and has no residues. It can be used as an alternative control drug to control certain insects resistant to Bacillus thuringiensis (Bt), and the development and utilization of Paecilomyces javanica has important economic significance. Paecilomyces javanica is widely distributed and has good control effects on red fire ants, spodoptera litura, whitefly and diamondback moth, etc., and has broad application prospects. [0003] Abamectins (Abamect...
