In recent years, borer pests have afflicted many kinds of street trees and flower shrubs in the northern urban greenbelts of many willows, sedges, Farnwood, Euonymus japonicus, and red-leaved eucalyptus, causing the upper part of the seedlings to die or even die from the base, resulting in serious losses. The harmful borer pests of the garden plants in Liaocheng, Shandong Province are Starbucks, Anoplophora glabripennis, Morus alba, Thornbill, Aromatica. We manage borer pests from the following aspects and received better control effects. Strengthen management and prevention First, prevention and control of borers and insect pests, we must first strengthen the management of conservation, the timely detection of locust damage during the growth phase to prevent and control its spread. During the winter season, the old insect-reducing insect trees with severe insect pests are removed, combined with pruning to remove the insect branches, and the insects are collectively burned and eliminated. Each phase has different control methods and adult stages. Tianniu from June to July is the peak of emergence, and from mid-June to mid-July (from Xingyue and Aromatic Muddy Moth from May to June), they are sprayed 1,000 times to 2000 times. 2.5% of the enemy killed or 200 times to 400 times 20% of chrysanthemum killing the adult. Second, the egg period. The borers of the borers of the borers are obvious (flowing gums are easy to identify), they can be wiped directly with a knife, or 5 times to 10 times 20% chrysanthemum oil, or 1-20 kilograms of kerosene and 2.5%. Enemy (Deltamethrin) mixture kills eggs and newly hatched larvae. Third, larval control. During the period of insect infestation, spray 500 to 800 times 20% of Chrysanthemum EC or 2.5% of enemies (Deltamethrin) on the branches. The amount of drug should be sprayed enough to allow the liquid to flow into the spawning trough. Newly hatched larvae. For mature larvae, use a 50% dibromo-phosphorus emulsifiable concentrate as a stock solution in a clean defecation hole and seal it with wet mud, or insert an aluminum phosphide toxin or aluminum phosphide plate and seal the defecation hole with wet mud. To kill larvae, syringes can also be used to inject 50- to 100-fold omethoate emulsifiable concentrate into the defecation hole, and then use a mortar seal to kill the larvae. When the larvae are damaged, wood chips are discharged and easily identified. As long as they are carefully managed, they will surely have good control effects. White bandage prevention before the first, painted white. 10 parts of quicklime, 1 part of sulfur powder, 0.2 parts of salt, 30 parts to 40 parts of water, and 0.2 parts of trichlorfon are used to adjust to a whitening agent. White is applied within 1.5 meters of the trunk of the victim tree during the eclosion stage. It can effectively prevent the breeding of eggs and the dangers of the calf. Second, bandaging. After spraying 1.5m to the base of the affected street tree to the base area, the woven bag or sack sheet or tying the straw rope is used for spraying. After spraying the trunk, a plastic film may be wrapped to prevent spawning of the beetle and other borer pests. harm. Third, sticky shellac. Non-polluted armyworm paste has the characteristics of non-toxic, non-irritating odor, non-corrosiveness, strong viscosity, no pollution, etc., and it has a long prevention and control time, is easy to operate and has a low cost, and can be directly applied to the affected parts for various types of borers. The prevention and treatment. Insecticide is also suitable for the prevention and treatment of the degeneration of the tree moth under various generations.
