Problems solved by technology

At present, the main control method is still chemical control, but the long-term chemical control not only leads to the resistance of potato beetle to cyclodiene, organochlorine, organophosphorus, carbamate and pyrethroid pesticides, also lead to resistance to new insecticides

Embodiment 1

[0016] The insecticide for killing potato beetles consists of the following components in parts by weight: 54-64 parts of Bacillus thuringiensis, 17-23 parts of Beauveria bassiana, 1-5 parts of synergist, 16-20 parts of dispersant, ultraviolet protection Dose 0.1-0.5 part.

[0017] The preparation method of the insecticide of killing potato beetle, the steps are as follows:

[0018] The bacillus thuringiensis and the beauveria bassiana are fully mixed in proportion to prepare a mixed bacterial agent, and then a synergist, a dispersant, and an ultraviolet protection agent are added to mix and process into a wettable powder.

Embodiment 2

[0020] The insecticide for killing potato beetles is composed of the following components in parts by weight: 60 parts of Bacillus thuringiensis, 20 parts of Beauveria bassiana, octyldodecanol: glycerol glucoside mass ratio is 1~2:2~13, 5 parts, MorwetD425 16 parts, xanthan gum 0.5 parts.

[0021] The preparation method of the insecticide of killing potato beetle, the steps are as follows:

[0022] Fully mix Bacillus thuringiensis and Beauveria bassiana in proportion to prepare a mixed bacterial agent, the mass ratio of octyldodecanol: glycerol glucoside is 1~2:2~1, MorwetD425, xanthan gum. It can be mixed and processed into wettable powder.

Embodiment 3

[0024] The potato beetle insecticide consists of the following raw materials and parts by weight thereof:

[0025] 58 parts of Bacillus thuringiensis, 20 parts of Beauveria bassiana, 3.7 parts of synergist, 18 parts of dispersant, 0.3 parts of ultraviolet protection agent. Octyldodecanol: glycerol glucoside mass ratio is 1~2:2~13, 7 parts, MorwetD425 18 parts, xanthan gum 0, 3 parts.

[0026] The preparation method of the insecticide of killing potato beetle, the steps are as follows:

[0027] Fully mix Bacillus thuringiensis and Beauveria bassiana in proportion to prepare a mixed bacterial agent, then add octyldodecanol: glycerol glucoside mass ratio of 1~2:2~1, MorwetD425, xanthan gum, and mix and process it into Wettable powder can be.

Abstract

The invention relates to an insecticide for killing potato beetles, which is prepared from the following components in parts by weight: 50 to 70 parts of bacillus thuringiensis, 15 to 25 parts of beauveria bassiana, 1 to 7 parts of synergist, 13 to 25 parts of dispersant, and 0.1 to 0.6 part of ultraviolet protective agent. The botanical insecticide provided by the invention is used for fruit trees, vegetables and tea trees. The insecticide has the advantages of simple composition, convenient preparation, obvious insecticidal effect and no residues, cannot pollute the soil, water source, fruits, vegetables and the like, and can be degraded in the natural environment.

Description

technical field [0001] The present invention relates to insecticides, in particular to insecticides for killing potato beetles. Background technique [0002] Potato beetle is a devastating quarantine pest in the world. It often reduces potato production by about 30%-50%, and can reduce production by 90% in severe cases. It also spreads potato brown spot and ring rot. Since the insect was introduced from Kazakhstan to Ili region and Tacheng in Xinjiang, my country, it has endangered the potato production in the entire northern Xinjiang region including Urumqi and Mulei counties. Wang Jun et al. [0003] The emergence of resistance to potato beetles has had a serious impact on potato production, greatly increasing production costs and reducing yields. At present, the main control method is still chemical control, but the long-term chemical control not only leads to the resistance of potato beetle to cyclodiene, organochlorine, organophosphorus, carbamate and pyrethroid pestic...
