Pine wood nematode disease infected wood stump treatment device and control method thereof

Abstract

The invention discloses a pine wood nematode disease infected wood stump treatment device and a control method thereof. The pine wood nematode disease infected wood stump treatment device comprises achemical device located at the top of a stump, a wrapping surface covering a side surface of the stump, and a plurality of fixing foot pads disposed at the bottom end of the wrapping surface; the chemical device comprises a chemical pressing surface and a control chemical layer, wherein the chemical pressing surface is disposed on an upper surface of the control chemical layer, and the chemical pressing surface is integrally laminated with the control chemical layer; the chemical device is integrally fixed with the wrapping surface through a sealing strip; and the fixing foot pads are evenly disposed along an edge of a bottom end of the wrapping surface. The Pine wood nematode disease infected wood stump treatment device further kills and blocks the pathogens of the pine wood nematode andmedia insects, and ensures that insects cannot fly out.

Description

technical field [0001] The invention relates to the field of prevention and control of forestry diseases and insect pests, in particular to a device for treating felling piles of pine wood nematode disease and a control method. Background technique [0002] Pine wood nematode disease, also known as pine cancer, can cause the whole pine tree to die. It is the number one forest disease in my country. Once it occurs, it is difficult to cure it. The pathogen is pine xylophilus, and the vector insects in my country are mainly pine longhorn beetle and spruce monochamus, etc. The removal of dead wood and the control of vector insects are important control links. [0003] The treatment of infested wood stumps involves both the removal of dead wood and the control of vector insects. The traditional method is to eliminate pests by applying pesticides and covering the stumps with plastic film. The general method is to peel the stumps and spray 16% Quetiafos Carbosulfan EC 1:100 times ...

AI Technical Summary

Problems solved by technology

This method can kill the vector insects in the felling pile to a certain extent, but due to the material problem of the plastic film, the complexity of the forest and mountain conditions, the limitation of climatic conditions and the destruction of humans and animals, the plastic film is easy to be damaged, and the airtightness cannot be guaranteed. Vector insects often fly out of damaged material during the eclosion period, causing the spread of the disease
