Method for protecting big greening tree against coptotermes formosanus

Abstract

The invention relates to a method for protecting a big greening tree against coptotermes formosanus. The method for protecting the big greening tree against the coptotermes formosanus comprises the steps that a hole is drilled in the trunk of the big greening tree by means of a drill bit with the length ranging from 30 cm to 50 cm and the diameter being 8.0 mm, the position where the hole is drilled is below an eclosion hole and is 15 cm-20 cm away from the ground, and the drill bit drills in the pith at the inclination angle of 35 degrees, wherein the depth of the drilled hole is larger than the radius of the trunk of the big greening tree; wood chips are removed after the hole is drilled, insecticide is sprayed into the drilled hole by means of a capsule duster, and the orifice of the drilled hole is blocked with waste paper or soil for three to seven days after the insecticide is sprayed into the drilled hole. The method for protecting the big greening tree against the coptotermes formosanus is simple, easy to implement, remarkable in control effect, low in cost and high in benefit, and the coptotermes formosanus control effect can reach over 95%; however, the coptotermes formosanus control effect of a traditional control method can only reach about 80%.

Description

technical field [0001] The invention relates to a method for preventing and treating termites in greening trees, and belongs to the field of agriculture. Background technique [0002] The large green trees over 30 years old mainly include ginkgo, camphor tree, sweet-scented osmanthus, yinxiang, maple, banyan, etc. These large trees have a long history of growth, and their tree vigor is weak. They are often damaged by domestic termites. Withered yellow, dry top, broken side branches, the trunk of the whole plant that suffered serious damage is hollow until dead, and the loss is serious. It is extremely unfavorable to greening and beautification, environmental protection, water and soil conservation, ecological balance and tourism development.

[0003] In the prior art, the prevention and control method of termites in greening big trees is to spray relevant chemicals when seeing termites walking on the tree trunk. Although termites die immediately when seeing termites, they only kill a small number of termites that were active outside at that time. The termites and ant kings are still in the nest, so the control effect is not significant; the other is to control the termites in the house from April to July when the activity of termites is more frequent, and the house termites disperse and cause damage. target of termites
