Embodiment 1
[0022] Embodiment 1: 20% Verticillium lecanii acetamiprid suspension concentrate (diluted 2000 times during use)
[0023] Part A is 40% conidia suspension of Verticillium lecanii: 40% conidia powder of Verticillium lecanii is dissolved in 0.21M phosphate buffer and 10% glycerol mixture, adjust pH 7.0, in Store at 4-8°C.
[0024] 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%.
[0025] Part A and Part B each account for 50%, and the two parts are directly mixed to obtain 20% Verticillium lecanii acetamiprid suspension concentrate, and the mass ratio of Verticillium lecanii:Acetamiprid is 100:10. The results of the toxicity test are shown in Table 1.
Embodiment 2
[0026] Embodiment 2: 50% Verticillium lecanii acetamiprid oil (diluted 2000 times during use)
[0027] Verticillium lecanii powder (10 10 each / g) 50%, acetamiprid 2% (commercially available), Tween-80 5%, paraffin oil 23%, methyl green 2%, add diatomaceous earth and mend to 100%, make 50% imitation green Myacetamiprid oil. Wherein, the mass ratio of Verticillium lecanii bacterial powder: acetamiprid is 100:4. The results of the toxicity test are shown in Table 1.
Embodiment 3
[0028] Embodiment 3: 60% Verticillium lecanii acetamiprid wettable powder (diluted 2000 times during use)
[0029] Verticillium lecanii powder (10 10 unit / g) 60%, acetamiprid 1% (commercially available), methyl green 2%, Tween-80 10%, sodium lignosulfonate 3%, wetting agent LX 2%, kaolin supplemented to 100% , to prepare 60% Verticillium lecanii acetamiprid wettable powder. Among them, the mass ratio of Verticillium lecanii bacteria powder: acetamiprid is 100:1.67. The results of the toxicity test are shown in Table 1.
