Poison stick for controlling tree trunk pests and making method thereof

Abstract

The invention provides a poison stick for controlling tree trunk pests and a making method thereof, relating to a forestry insect pest control technology. In the poison stick, a stick body is a wood or bamboo section, a stick tip is arranged at the front end of the stick body, and the end of the stick body is coated with a poison layer and a protective film layer from inside to outside. When in use, the poison stick is inserted into a pest tunnel, poison is in contact with sap and moisture of pests to generate chemical reaction and form a poisonous phosphine gas, the phosphine gas fills the pest tunnel, and pests in the pest tunnel die from poisoning to reach the control purpose. The invention has the following advantages of long usable period (used in all larva active stages within a year), long validity life, wide applicability, high insecticide efficiency, natural enemy protection, safety and convenience for use, economy, labor saving, good poison effect on trunk pests of longicornia, buprestid, janus piri, grape clearwing moths and the like which do harm to trees including apple trees, pear trees, peach trees, jujube trees, poplars, mulberries and the like, is simple and easy for operation without environmental pollution and is suitable for popularizing in a large scale.

Description

technical field [0001] The invention relates to forestry pest control technology, and further relates to a poisonous swab for preventing and controlling tree pests and a manufacturing method thereof. Background technique [0002] In recent years, stem-boring pests have generally occurred in my country, causing serious harm, large economic losses, and difficult control. There are 4 types of borer pests, namely, longhorn beetles, jerky beetles, pear stem beetles, and grape penetrating moths. The beetle is the most serious hazard. There are several kinds of long beetle pests, but the main ones are mulberry long beetle, star long beetle, apple branch long beetle, peach red neck beetle, etc. These larvae eat into the branches of trees, and the light ones cause the leaves of the trees to fall, the branches to break, and the wood to grow. Or the fruit quality and yield will decline, and the whole plant will die in severe cases. They harm fruit trees such as apples, pears, plums,...

AI Technical Summary

Problems solved by technology

[0003] Generally, the prevention and control of borer pests mainly rely on methods such as medicinal mud, cotton plug holes, and liquid injection. However, due to the deep insect passage, bending up and down, and blockage of insect feces, the insecticidal effect is not ideal.
