Embodiment 1

[0024] Example 1 Preparation of 25% Beauveria bassiana buprofezin suspension concentrate (diluted 2000 times)

[0025] Part A is 50% Beauveria bassiana conidia suspension: 50% Beauveria bassiana conidia powder (accounting for 50% of suspension mass) dissolved in 0.21M phosphate buffer and 10% glycerol In the mixed solution, pH 7.0, store at 4~8°C.

[0026] Part B is wettable powder: Buprofezin (commercially available original drug) 8%, Tween-80 20%, sodium lignosulfonate 6%, wetting agent LX 4%, add clay to make up to 100%.

[0027] Part A and Part B each account for 50%, and the two parts are mixed directly to obtain 25% Beauveria bassiana buprofezin suspension concentrate, and the mass ratio of Beauveria bassiana: Buprofezin is 100:16. The results of the toxicity test are shown in Table 1.

Embodiment 2

[0028] Example 2 Preparation of 50% Beauveria bassiana buprofezin oil (diluted 2000 times)

[0029] Components of the oil agent: Beauveria bassiana conidia powder (10 10 a / g) 50%, buprofezin (commercially available) 4%, Tween-80 5%, paraffin oil 23%, methyl green 2%, add diatomaceous earth to make up to 100%, and make 50% coccidioides Beauveria bassiana buprofezin oil. Among them, the mass ratio of conidia powder of Beauveria bassiana: Buprofezin is 100:8. The results of the toxicity test are shown in Table 1.

Embodiment 3

[0030] Example 3 Preparation of 60% Beauveria bassiana buprofezin wettable powder (diluted 2000 times)

[0031] Components of wettable powder: Beauveria bassiana conidia powder (10 10 / g) 60%, buprofezin (commercially available) 4%, methyl green 2%, Tween-80 10%, sodium lignosulfonate 3%, wetting agent LX 2%, kaolin to 100%, Prepare 60% Beauveria bassiana buprofezin wettable powder. Among them, the mass ratio of conidia powder of Beauveria bassiana: Buprofezin is 100:6.67. The results of the toxicity test are shown in Table 1.

Abstract

The invention discloses a Beauveria bassiana-buprofezin compound pesticide and application thereof. The compound pesticide is composed of the following components in percentage by mass: 5-65% of main agent and 35-95% auxiliary agent. The main agent is a mixture of Beauveria bassiana and buprofezin in a mass ratio of 100:(1-20); and the auxiliary agent is composed of a stabilizer, assistants and a filler. The compound pesticide can be processed into wettable powder, suspending agents or oil solutions. The long-term infective biological research and indoor bioassay indicate that the Beauveria bassiana has high infective pesticidal effect on multiple pests, especially pests with piercing-sucking mouthparts. The compound pesticide has favorable preventing and treating effect on sweetpotato whitefly, Trialeurodes vaporariorum and other aleyrodids, and smaller green leafhoppers of tea and other leafhoppers.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to a microbial pesticide. More specifically, it relates to an environment-friendly, pollution-free and residue-free compound insecticide of Beauveria bassiana and buprofezin. Background technique [0002] Beauveria bassiana ( Beaueria bassaria (Balsamo) Vuillemin) is an entomopathogenic fungus. As a living biological pesticide, it has a new mechanism of action different from existing chemical insecticides, and has the characteristics of no pollution to the environment and no residue. It is of great economic significance to develop and utilize Beauveria bassiana as an alternative control drug for chemical insecticide-resistant pests. Beauveria bassiana is widely distributed and is used to control grubs, houseflies, scale insects, whiteflies, aphids, thrips, potato leaf beetles, cockroaches, locusts, grasshoppers, crickets, cotton boll weevils, cotton hop bugs, corn borers, and beet...
