Problems solved by technology

[0003] However, the method of perforating insecticide bottles or injecting medicine with hanging needles will damage the cambium of trees, thereby producing callus tissue, such as wound resin ducts, which will secrete a large amount of resin and block the channels through which the medicinal liquid penetrates. Affect the continuity and utilization of liquid medicine absorption

Embodiment 1

[0031] Pharmaceutical formula: 1500 parts by weight of water, 3 parts by weight of 5% esfenvalerate 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 ingredients evenly and set aside.

[0032] The tree diameter at breast height is 4cm, and a perfusion hole is drilled at an angle of 40° obliquely downward on the trunk above 3m from the ground, with a diameter of 6mm and a depth of 4cm. Late April was selected as the application period, 3ml was applied to each well, once every 15 days, and applied 3 times in a row. After spraying each time, use plastic film to temporarily seal the tree hole, and after the last spraying, use yellow mud to completely seal the tree hole.

Embodiment 2

[0034] Pharmaceutical formula: 2000 parts by weight of water, 4 parts by weight of 15% cypermethrin emulsifiable concentrate, 4 parts by weight of 45% dichlorvos emulsifiable concentrate, 2 parts by weight of Resinase A, and 2 parts by weight of trisiloxane polyoxyethylene ether. Mix the above ingredients evenly and set aside.

[0035] The diameter at breast height of the tree is 15cm, and 3 perfusion holes are drilled obliquely downward at a 45° angle on the trunk above 3m from the ground, with a diameter of 7mm and a depth of 5cm. The interval is 15cm. Choose late June as the application period, apply 4ml per well, apply once every 18 days, and apply 4 times in a row. After spraying each time, use plastic film to temporarily seal the tree hole, and after the last spraying, use yellow mud to completely seal the tree hole.

Embodiment 3

[0037] Pharmaceutical formula: 1800 parts by weight of water, 5 parts by weight of 20% fenpropathrin emulsifiable concentrate, 5 parts by weight of 50% omethoate emulsifiable concentrate, 3 parts by weight of Resinase A, and 3 parts by weight of trisiloxane polyoxyethylene ether. Mix the above ingredients evenly and set aside.

[0038] The diameter at breast height of the tree is 25cm, and 5 perfusion holes are drilled obliquely downward at an angle of 50° on the trunk above 3m from the ground, with a diameter of 8mm and a depth of 5cm. The interval is 20cm. The last ten-day of August was selected as the application period, and 6ml of drug was applied to each hole, once every 15 days, and applied continuously for 5 times. After spraying each time, use plastic film to temporarily seal the tree hole, and after the last spraying, use yellow mud to completely seal the tree hole.

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...
