Problems solved by technology

Since the plant galls are built inside the plant tissue, the pests in the galls are protected, and the spraying on the surface basically cannot kill the pests, and the insecticidal effect is not obvious; 2. For plants with less damage, Cut off 1 to 2-year-old branches and leaves after spraying pesticides, and burn or bag and seal the cut branches and leaves. For plants with serious damage, cut off the trunk after spraying pesticides, and burn the whole plant or bag and seal. The method can not reach the effect of curing the root cause; 3. Embedding medicine in the roots, burying carbofuran and other medicines in the roots of trees for root application, the control effect is below 50%, and the medicine remains in the soil, which is not conducive to environmental protection

Embodiment Construction

[0019] The following specific steps can be taken to implement the prevention and treatment method of the present invention:

[0020] 1. Clean up the fallen leaves, dead branches, flower buds and pods around the damaged trees, and burn the fallen leaves, dead branches, flower buds and pods with galls in time;

[0021] 2. Mark the drilling position on the surface of the tree base 20-60cm above the ground. The positions of the holes are divided into upper and lower rows, and the height of each row is the same; each hole forms an equilateral triangle with two adjacent holes in the other row; Φ20cm Drill one hole at an average interval of 8-10cm for trees below Φ20-40cm; drill one hole at an average interval of 10-12cm for trees above Φ40cm; drill one hole at an average interval of 15-20cm for trees above Φ40cm; figure 1 It shows the positional relationship of the two rows of holes after the simulation of the tree surface is unfolded. On the tree surface 1, the holes 2, 3, and 5 ar...

Abstract

The invention provides a control method of tree insect gall. Tree insect gall is controlled by injecting systemic insecticides into tree body. The method has the advantages of good insecticidal effect, death rate of pest in insect gall as high as 100%, no harm on tree, no phytotoxic phenomenon, no environmental pollution, low cost, simple operation and low labor intensity.

Description

technical field [0001] The invention relates to a method for preventing and controlling plant diseases and insect pests, in particular to a method for preventing and controlling tree galls which has good insecticidal effect and is harmless to the environment. Background technique [0002] Tree galls are a deformed structure in which plant tissues are stimulated by insect secretions and cell division accelerates. It can vary in shape and is usually sac-shaped, spherical, or cylindrical. The occurrence of tree galls is usually caused by the invasion of insects such as aphids, scale insects, wasps, sawflies, and gall midges. In the epidermal tissue of petioles, twigs or young shoots, larvae feed on mesophyll tissue after hatching and secrete stimulating hormones, causing cells in the injured part of the tree to accelerate division, the mesophyll tissue is deformed, and the injured part gradually expands to form galls. [0003] Galls mainly occur on the leaves, petioles, buds ...
