Abstract

The invention belongs to the field of biological control, and in particular relates to the application of diosgenin in preventing and controlling pine nematode diseases. The diosgenin described in the present invention is a steroid compound connected by a spirosterane-type diosgenin and a glycogen connected to the 3-hydroxyl through a β-1,3 glycoside bond, including dioscin-like glycosides pachyphyllin and slender Dioscin. The diosgenin can be added to a pesticide carrier or composition as an active ingredient of a drug to make a pesticide, and then the common pesticide dosage form and application method can be used to prevent and control pine nematode diseases. The diosgenins described in the present invention are all derived from the tubers of the Dioscoreaceae purple yellow ginger, are harmless to the human body, and are easy to degrade in the environment. The disease control effect is better than the current conventional chemical nematicide matrine, which meets the needs of green environmental protection and sustainable agricultural production and development.

Description

technical field

[0001] The invention belongs to the field of biological control, and in particular relates to the application of diosgenin in preventing and controlling pine nematode diseases. Background technique

[0002] Pine wilt disease, also known as pine wilt disease, is a devastating epidemic of pine trees, caused by pine wood nematodes, and brings huge ecological disasters to forestry production. Under normal circumstances, pine xylophilus parasitizes inside pine wood. The nematode has a body length of 1 mm, and the overall appearance is slender. Every year when summer comes, the young shoots of newly grown pine trees will be gnawed by longhorns, and pine xylophilus can quickly enter the forest tree through the gnawed tree skin, and then stay inside the pine tree. Once the pine wood is infected, the epithelial cells and resin ducts of the forest wood will be quickly destroyed, resulting in the loss of transpiration of the pine wood, so that the whole plant shows a s...
