Embodiment 1

[0015] Embodiment 1: 30% Acetamiprid suspension concentrate (diluted 2000 times)

[0016] Part A is 60% A. whitefly conidia suspension: 60% A. whitefly A. whitefly conidia powder is dissolved in 0.21M phosphate buffer and 10% glycerin mixture, pH7.0 . Store at 4-8°C.

[0017] Part B is wettable powder: acetamiprid (commercially available) 4%, Tween-80 20%, sodium lignosulfonate 6%, wetting agent LX 4%, add 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 a 30% A. whitefly acetamiprid suspension concentrate. The mass ratio of A. whitefly: acetamiprid is 100:6.67. The results of the toxicity test are shown in Table 1.

Embodiment 2

[0019] Embodiment 2: 50% Acetamiprid oil preparation of A. whitefly (2000 times of dilution)

[0020] Whitefly Ascospora powder (10 10 Individual / g) 50%, acetamiprid 2% (commercially available), Tween-805%, paraffin oil 23%, methyl green 2%, add diatomaceous earth and make up to 100%, make 50% whitefly seat Acetamiprid oil. Wherein, the mass ratio of Ascospora whitefly:Acetamiprid is 100:4. The results of the toxicity test are shown in Table 1.

Embodiment 3

[0021] Embodiment 3: 60% Acetamiprid wettable powder (diluted 2000 times)

[0022] Whitefly Ascospora powder (10 10 each / g) 60%, acetamiprid 1% (commercially available), methyl green 2%, Tween-80 10%, sodium lignosulfonate 3%, wetting agent LX 2%, kaolin supplemented to 100%, A 60% wettable powder of Ascospora acetamiprid was prepared. Wherein, the mass ratio of Ascospora whitefly powder: acetamiprid is 100:1.67. The results of the toxicity test are shown in Table 1.

Abstract

The invention discloses a combination pesticide of aschersonia aleyrodis webber and acetamiprid, comprising 32 to 61 percent of host crystal and 39 to 68 percent of adjuvant according to mass percent, the host crystal is the mixture of aschersonia aleyrodis webber and acetamiprid, the mass ratio of the aschersonia aleyrodis webber and the acetamiprid is 100: 1.67 to 6.67; the adjuvant is stabilizer, addition agent and filler. The invention discloses that the combination pesticide of aschersonia aleyrodis webber and acetamiprid is processed into wettable powder, suspending agent or medicinal oil. After long-term infection biology research and indoor biological assay, the aschersonia aleyrodis webber of the pesticide of the invention has rather strong infection disinsection effect on various pests, especially has good control effects on pests such as whitefly and aphis, etc.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and specifically relates to a microbial insecticide, in particular to an environmentally friendly, pollution-free and residue-free compound insecticide of Ascospora whitefly and acetamiprid. Background technique [0002] Aschersonia aleyrodis Webber 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 residue. As an alternative control drug to control some insects resistant to Bt, it is of great economic significance to develop and utilize A. whitefly. The whitefly, Ascospora, is widely distributed and has a good control effect on the piercing-sucking mouthparts such as aphids and whitefly, and has a good application prospect. [0003] Acetamiprid (acetamiprid) is a new type of nicotinic insecticide currently used with contact killing, stomach poisoning, penetrat...
