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

The invention provides a treatment method for quarantine and pest control of Pycoccus lycoris. By using conidia of Beauveria bassiana and imidacloprid to prepare a compound agent, the synergistic function of conidia of Beauveria bassiana and imidacloprid can be fully exerted, and the The lethality of the conidia of Beauveria bassiana shortens the time of killing insects, improves the efficiency of killing insects, and significantly inhibits the feeding behavior of P. amaryllis. The application rate of imidacloprid will not affect the treated objects on the basis of eliminating pests. It is an efficient and environmentally friendly method for quarantine and pest elimination of Amaryllis lycoccus, which fully meets the requirements of quarantine treatment.

Description

technical field [0001] The invention belongs to the field of prevention and control of plant diseases and insect pests, and in particular relates to a method for quarantine and elimination of pests of Amaryllis lycoccus. Background technique [0002] Solanum mealybug scientific name: Phenacoccus solani Ferris, belongs to Hemiptera, Coccoidea, Pseudococcidae, Phenacoccina, Phenacoccus genus (Phenacoccus) cotton mealybug (Phenacoccus). Amaryllis cottonis is a piercing-sucking insect with parthenogenetic reproduction. Its body is oval and covered with a thick layer of waxy powder. It mainly passes adults and nymphs along with host plants or other media (such as soil etc.) long-distance transmission and diffusion. [0003] P. amaryllis has been intercepted many times in the quarantine of succulent plants at the import ports of Guangxi, Zhejiang, Yunnan, Jiangsu and other places in my country since 2014. It is an invasive pest that has been focused on prevention and control in ...
