Example Embodiment

[0030] Example 1

[0031] Pharmaceutical formulation: 1500 parts by weight of water, 3 parts by weight of 5% fenvalerate EC, 3 parts by weight of 40% dimethoate EC, 1 part by weight of Resinase A, and 1 part by weight of trisiloxane polyoxyethylene ether. Mix the above-mentioned raw materials uniformly and set aside.

[0032] The tree has a diameter at breast height of 4cm. Drill a perfusion hole with a diameter of 6mm and a depth of 4cm at an angle of 40° on the trunk above the ground 3m. Choose late April as the application period, with 3ml of medicine per hole, once every 15 days, and 3 times in a row. After each application, the tree hole is temporarily sealed with plastic film, and after the last application, the tree hole is completely closed with yellow mud.

Example Embodiment

[0033] Example 2

[0034] Pharmaceutical formulation: 2000 parts by weight of water, 4 parts by weight of 15% cypermethrin EC, 4 parts by weight of 45% dichlorvos EC, 2 parts by weight of Resinase A, and 2 parts by weight of trisiloxane polyoxyethylene ether. Mix the above-mentioned raw materials uniformly and set aside.

[0035] The tree has a diameter at breast height of 15cm. Drill 3 perfusion holes obliquely downward at a 45° angle on the trunk above the ground 3m, with a diameter of 7mm and a depth of 5cm. The holes and holes should rise in a spiral shape and be evenly distributed around the tree, with a distance of at least 15cm apart. Choose late June as the application period, and use 4ml per hole, once every 18 days, for 4 consecutive applications. After each application, the tree hole is temporarily sealed with plastic film, and after the last application, the tree hole is completely closed with yellow mud.

Example Embodiment

[0036] Example 3

[0037] Pharmaceutical formulation: 1800 parts by weight of water, 5 parts by weight of 20% fenpropathrin EC, 5 parts by weight of 50% omethoate EC, 3 parts by weight of Resinase A, and 3 parts by weight of trisiloxane polyoxyethylene ether. Mix the above-mentioned raw materials uniformly and set aside.

[0038] The tree has a diameter at breast height of 25cm. Drill 5 perfusion holes diagonally downward at a 50° angle on the trunk above 3m from the ground, with a hole diameter of 8mm and a depth of 5cm. The holes and holes should rise in a spiral pattern and be evenly distributed around the tree, with a distance of at least The interval is 20cm. Choose late August as the application period, and use 6ml per hole, once every 15 days, for 5 consecutive applications. After each application, the tree hole was temporarily sealed with plastic film, and after the last application, the tree hole was completely closed with yellow mud.

Abstract

The invention discloses a perfusion method for preventing diseases and insect pests in a tree. The method includes the steps of insecticide preparation, hole drilling, insecticide application, hole sealing and the like. Firstly, 1500-2000 parts by weight of water, 3-6 parts by weight of pyrethroid insecticide, 3-6 parts by weight of organic phosphorus insecticide and 1-3 parts by weight of hydrolytic enzyme are mixed evenly and reserved. Perfusion holes are drilled on the trunk more than 3m away from the ground at the angle of 40-50 degrees in inclined downward mode, hole diameter is 6-8mm, hole depth is 4-5cm, one hole is drilled if diameter at breast height of a tree is <=5cm, one more hole is drilled if each 5cm is increased in the diameter of breast height, and the holes are intersects, rise in a spiral shape and are evenly distributed around the periphery of the tree. 3-6ml insecticide is filled in each hole, the insecticide is applied every 15-20 days, and the tree holes are sealed totally after the insecticide is applied for 3-5 times continuously. The hydrolytic enzyme in the method has decomposition function for resin secreted by the tree body, so as to reduce the influence for medicine permeability caused by the inset damages and a large number of resinosis easily after wound processing.

Description

technical field [0001] The invention belongs to the field of prevention and control of tree diseases and insect pests, and in particular relates to a perfusion method for preventing and controlling plant diseases and insect pests, which has high drug utilization rate, good absorption persistence, and is especially effective for insect pests and tree species that are prone to a large amount of sebum after wound treatment. Background technique [0002] Boring pests are one of the main pests that harm trees. Because the pests penetrate into the tree and harm the big tree, it is difficult for the common spray method to make the pesticide contact the pest in the tree, so the effect is relatively poor. The method of punching and inserting insecticide bottles and injecting medicine with hanging needles to prevent and control large tree pests is an effective way to solve the refractory problems of scale insects, leaf rollers and tree borers in tall trees. After spraying, the medici...
