Abstract

The invention discloses a method for preventing and treating plutella xylostella by applying lemongrass essential oil and belongs to the technical field of agricultural pest control. The method comprises the following steps of: (1) preparation of solution; (2) preparation of prevention and treatment and / or repellent liquor; (3) prevention and treatment of larvae of the plutella xylostella; (4) repellent application of oviposition of the plutella xylostella; and the like. The method has 31.7 percent to 67.3 percent of preventing and treating effect on the larvae of the plutella xylostella and has 30.4 percent to 72.7 percent of repellent effect on the oviposition of the plutella xylostella. The lemongrass essential oil is a vegetative pollution-free product. According to the invention, thevarieties of medicaments for preventing and treating the plutella xylostella are increased, the harmful effect of conventional pesticides on the environment can be reduced, and the method has obviousecological benefit and social benefit. The method can be popularized and applied in vegetable production areas.

Description

technical field [0001] The invention relates to the technical field of agricultural pest prevention and control, in particular to a method for comprehensive prevention and control of diamondback moth by using lemongrass essential oil, a plant essential oil. Background technique [0002] The diamondback moth (Plutella xylostella L.) belongs to Lepidoptera Plutellaidae, is a worldwide herbivorous pest, with more than 40 species of hosts, and mainly damages cruciferous vegetables. Since diamondback moth became the main pest of cruciferous vegetables in my country in the 1970s, it has been seriously occurring in southern provinces such as Guangdong, Hainan, Fujian, Yunnan, and Hubei. In the past ten years, with the adjustment of the planting structure in the north and the expansion of the vegetable planting area, the occurrence and damage of diamondback moth have also shown an obvious upward trend. Plutella xylostella has many generations, serious overlapping of generations, fa...
