Drilling pest control method of garden trunk pests
The tall and straight poplars on the side of the shady path and the whirling willows will give people unlimited imagination and beauty. However, once the trunks of these green trees have been penetrated by pests such as Populus tregans, Mulberry, Anoplophora glabripennis, Mongolica moth, and Mossina sinensis, the light leaves fall and the whole plant dies. This type of pest control camp conceals life, and it is difficult to achieve general chemical control. The use of poisoning fumigation control is an ideal method, with the advantages of simple operation, labor saving, low cost, protection of natural enemies and so on. 1, the principle of prevention. After the poison stick is inserted into the insect tract, the medicine reacts with the moisture of the sap and the insects to produce a chemical reaction and form a highly toxic gas, phosphine, which kills the insect pests in the insect tract and achieves the purpose of control. 2, poisonous sign production. First, press the glue solution (11% for zinc phosphide, 58% for Gum arabic, and 31% for water) and place the water and glue in a beaker. Heat the water bath to 80°C, and add the zinc phosphide after the glue is dissolved. be usable. After the acid glue solution (oxalic acid 10%, gum arabic 56%, water 34%) will be added to the water and oxalic acid in another beaker, the water bath heated to dissolve oxalic acid, after adding the Arab Gum dissolved, mix well to use. Then use bamboo sticks (7-10 cm long and 0.1-0.2 cm in diameter) to pick up the zinc phosphide solution. The length of the drug is 2 cm. Invert the shade and dry for 2-4 hours. Place the shikimic acid glue on the outside and invert the shade. to make. Then seal the damp-proof and place it in a cool, dry place. 3, check in the hole. Use the drug-free end to check the direction, depth, and size of the fistula, then insert the end of the drug into the fistula, 4-6 cm deep, one per well. After inserting the sign, seal it with yellow mud to prevent air leakage. The insecticidal effect is over 90%. The use of poisonous picks to control garden trees and stem pests is better for saplings up to five years of age. If the trees are too large and the boring holes are too high, it will be difficult to find boring holes and it will be easy to leak them, which will bring certain difficulties to prevention and control. In spring, summer and autumn larvae, they can all be controlled according to this method.
