Pesticide application method for handling monochamus alternatus in bursaphelench xylophilus diseased wood

Abstract

In a bursaphelench xylophilus disease area, dead and dying trees whose forest stand is not cleared and pines around houses of farmers are collected on the spot before the eclosion and migration of monochamus alternatu imagoes, and are cut into wood segments with length less than 2 cm, thiamethoxam moiety powder is sprayed on the wood segments, and the wood segments are tightly covered by plastic films. The handled wood segments can be used as fuel wood whenever being taken, and after being used, the handled wood segments are covered tightly. By the next summer, monochamus alternatus in the forest stand of the handled wood segments died, and the monochamus alternatu imagoes cannot lay eggs on the wood segments and decompose and decay voluntarily after the plastic films are opened. The pesticide application method for handling the monochamus alternatus in the bursaphelench xylophilus diseased wood can effectively reduce the amount of the monochamus alternatus, and thereby the spreading of the bursaphelench xylophilus disease is controlled, people and livestocks cannot be damaged, time and labor are saved, and the cost is low.

Description

technical field [0001] The method relates to a pesticide application method for chemically preventing and controlling insects, in particular to a pesticide application method for treating pine wood nematode diseased wood infestation. Background technique [0002] Controlling the population of pine brown monochamus in the forest is the main way to control pine wood nematode disease, and it is also an effective means. For a long time, people have usually used the method of burning infested wood and chemical control to reduce the monochamus in the stand. There is a great fire hazard in burning infected wood in the forest, and the cost of burning after clearing out the forest stand is very high, and it is difficult to clean up completely, and it is easy to leave dead ends. The pine logs in the epidemic area are piled up in front of and behind the house, causing hidden dangers. The usual chemical control is spraying by aircraft or spraying artificially in the forest.

There is a great fire hazard in burning infected wood in the forest, and the cost of burning after clearing out the forest stand is very high, and it is difficult to clean up completely, and it is easy to leave dead ends. Stack pine logs in the epidemic area in front of and behind the house, causing hidden dangers

The usual chemical control is spraying by aircraft or spraying artificially in the forest. This method will waste a lot of pesticides, is time-consuming and labor-intensive, has a great impact on the environment, and the control effect is not ideal.
