Embodiment 1

[0040] Embodiment 1 Beauveria bassiana conidia 4 * 10 9 pcs / mL+imidacloprid 2mg / L

[0041] Compounding of the medicines was carried out on site, and the concentration of the conidia suspension of Beauveria bassiana was 4×10 9 per mL, add imidacloprid so that the concentration of imidacloprid in the final mixture is 2 mg / L. After fully mixing, use a sprayer to form a mist with a pressure of 0.1-0.2MPa. The median diameter of the droplets is 150-250μm, and spray it evenly on the surface of the plants. 15-20 mL of leaf surface area. Close the container.

Embodiment 2

[0042] Embodiment 2 Beauveria bassiana conidia 8 * 10 9 pcs / mL+imidacloprid 8.5mg / L

[0043] Compounding of medicines is carried out on site, and the concentration of conidia suspension of Beauveria bassiana is 8×10 9 per mL, add imidacloprid so that the concentration of imidacloprid in the final mixture is 8.5 mg / L. After fully mixing, use a sprayer to form a mist with a pressure of 0.1-0.2MPa. The median diameter of the droplets is 150-250μm, and spray it evenly on the surface of the plants. 15-20 mL of leaf surface area. Close the container.

Embodiment 3

[0044] Embodiment 3 Beauveria bassiana conidia 1.2 * 10 10pcs / mL+imidacloprid 12.5mg / L

[0045] The difference from Example 2 is that the concentration of the beauveria bassiana conidia suspension is 1.2×10 10 / mL, the concentration of imidacloprid is 12.5mg / L. Adopt the method as provided in Example 2 to process.

Abstract

According to a quarantine disinfestation treatment method for Phenacoccus solani Ferris, beauveria bassiana conidia and imidacloprid are adopted for preparing a compound pesticide, the synergistic interaction function of the beauveria bassiana conidia and the imidacloprid is fully played, the lethal force of the beauveria bassiana conidia is improved, the pest-killing time is shortened, the pest-killing efficiency is improved, the feeding behavior of the Phenacoccus solani Ferris is obviously inhibited, the pest killing effect on the Phenacoccus solani Ferris is 95% or above, the application amount of imidacloprid is greatly reduced, an object to be treated is not affected on the basis of pest killing, the method is an efficient and environment-friendly Phenacoccus solani Ferris quarantine pest killing treatment method, and the quarantine treatment requirement is completely met.
