Problems solved by technology

However, the research on the insecticidal activity of the larvae of the American white moth has not been reported in China. Therefore, we extracted the OS from Cnidium chinensis to study the insecticidal activity of the American white moth larvae, in order to provide new ideas for the control of the American white moth. and way

Embodiment 1

[0014] Preparation of HP-β-CD inclusion complex

[0015] Take about 120g of HP-β-CD and place it in a three-neck flask, add 120ml of distilled water, and stir to dissolve the HP-β-CD. Add 2.5 g of osthole into the HP-β-CD solution, stir continuously at room temperature or 30°C (stirring speed is about 500r / min), continue inclusion for 24 hours or until the drug is completely dissolved, filter with suction, and spray the filtrate Dry or freeze-dry to obtain white loose granules (osthole HP-β-CD inclusion complex) and then add appropriate amount of excipients to prepare 2% osthole HP-β-CD inclusion complex granules.

Abstract

The invention belongs to the technical field of pesticide, in particular to application of osthole for preparing a preparation for killing hyphantria cunea drury. The invention provides a preparation which contains 0.0001 percent-99.9999 percent of osthole and 99.9999 percent-0.0001 percent of excipient and a method which does not need an organic solvent when the preparation is prepared and has good water dispersibility, high chemical stability and convenient storage and transportation. The prepared preparation has more favorable touch killing effect on the hyphantria cunea drury and is safe to people, livestock and other mammals. Compared with common chemical pesticides, the invention is more beneficial to the environmental protection, has the characteristics of safety, high efficiency, short residual period, no poison, no pollution and convenient use, storage and transportation, and is novel hyphantria cunea drury insecticide.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to the application of osthole in preventing and treating white moth. Background technique [0002] American Bai'e [Hyphannlria cunea (Drury)] belongs to Lepidoptera, Diphrididae, and Drury genus. The insect has a wide range of hosts, a large number of reproduction, strong adaptability, and wide transmission routes. It is a serious world quarantine pest. It is the main leaf-eating pest. It first occurred in Dandong in China, and it has commonly occurred in Liaoning and Hebei in recent years, causing serious damage. For many years, the combination of artificial control and chemical drug control has been adopted, and the principle of chemical drug control is the main control method. However, such agents are highly toxic and have high residues. A large number of chemical pesticides are used to control pests, which has caused serious pollution to the environment. In addition, these ...
