Description

Technical Field

[0001] This invention relates to the field of pest and disease control, and in particular to a method for controlling pests and diseases in hickory. Background Technology

[0002] Pecan, also known as long pecan or common pecan, belongs to the genus *Caragana* in the family Juglandaceae. It is an ecologically and economically valuable tree species that integrates high-grade dried fruit, landscaping, woody oil, and precious timber. However, pecans still face threats from pests and diseases. For example, diseases such as black spot and brown spot, as well as leaf-eating pests such as tussock moths, longhorn beetles, and scarab beetles can seriously affect the growth of pecan trees and even cause their death.

[0003] Currently, pests and diseases can be eliminated by spraying insecticides, such as spraying insecticides under the tree trunk or whitewashing the trunk to prevent insects from climbing the tree and enhance the tree's resistance. However, existing insecticide spraying methods are generally manual, with people carrying pesticide tanks and moving through the walnut grove to spray insecticides. While this can achieve some pest control, it is physically demanding and cannot provide long-term, sustainable pest and disease control. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a method for the prevention and control of pests and diseases in hickory. This method achieves continuous pest and disease control by automatically dripping insecticide from a pesticide tank. Personnel only need to add insecticide to the pesticide tank, eliminating the need for manual spraying and saving physical effort.

[0005] The technical solution of the present invention, a method for controlling diseases and pests of hickory, includes the following steps:

[0006] S1. Add the prepared insecticide to the pesticide tank;

[0007] S2. Secure multiple medicine boxes to the outer perimeter of the walnut tree trunk using hook and loop fasteners and straps;

[0008] S3. Apply insect-repellent adhesive to the outer surface of the hook and loop fastener;

[0009] S4. The insecticide seeps out from the bottom of the pesticide tank and drips around the base of the tree trunk, forming a ring of insect-repelling area at the base of the tree trunk. When the wind blows, the insecticide droplets are scattered around.

[0010] S5. Observe the remaining amount of insecticide inside the insecticide box through the transparent window, and replenish it in time when the insecticide is insufficient.

[0011] Preferably, the insecticide is chlorpyrifos, cypermethrin, or thiamethoxam, and multiple pesticide tanks contain different types of insecticides.

[0012] Preferably, the insecticide comprises the following raw materials in parts by weight: 5-7 parts of emamectin benzoate, 2-4 parts of hydroxyapatite, 2-3 parts of potassium dihydrogen phosphate, 7-8 parts of photosynthesis inducer, 7-10 parts of copper sulfate, 4-5 parts of sodium diacetate, 2-3 parts of permethrin, and 6-7 parts of polysorbate.

[0013] Preferably, the method further includes step S6, using an agricultural drone to spray pesticides downwards from above the hickory tree.

[0014] Preferably, hook and loop fasteners pass through the sleeve plate on the back of the medicine box, and straps are tied around the periphery of multiple medicine boxes.

[0015] Preferably, a stirring component is rotatably installed on the side of the pesticide tank, which agitates the pesticide inside the tank when the wind blows.

[0016] Preferably, a spraying assembly is installed at the bottom of the pesticide tank. The spraying assembly includes a rotating drum installed at the bottom of the pesticide tank and a second fan blade located at the bottom of the rotating drum. The rotating drum has an upward-facing flow channel and is connected to the pesticide tank through the flow channel. The rotating drum has multiple evenly distributed seepage holes on its side. The insecticide flows downward through the flow channel to the seepage holes and drips outward through the seepage holes. When the wind blows, the insecticide droplets are directly dispersed by the wind, or dispersed or scattered by the rotating fan blade.

[0017] Preferably, in winter, diseased branches, leaves, and fruits on walnut trees are removed and burned.

[0018] Compared with existing technologies, this invention has the following beneficial technical effects: This invention achieves continuous pest and disease control by automatically dripping existing or formulated insecticides from a pesticide tank. Under its own gravity, the insecticide seeps out from the seepage holes and drips downwards, forming an insect-control zone around the base of the walnut tree trunk, preventing insects from climbing the tree. When the wind blows, the spraying component can be used to spray the insecticide, expanding the control area. Personnel only need to add insecticide to the pesticide tank; there is no need for manual spraying, saving physical effort. Attached Figure Description

[0023] Example 1

[0024] like Figures 1-3 As shown in this embodiment, a method for controlling pests and diseases in pecans includes the following steps:

[0025] S1. Add the prepared insecticide to the pesticide tank 3. The insecticide is chlorpyrifos, cypermethrin, or thiamethoxam. Different types of insecticides are contained in multiple pesticide tanks 3. For example, chlorpyrifos, cypermethrin, and thiamethoxam are contained in three pesticide tanks 3 respectively. Alternatively, the same type of insecticide can be added to different pesticide tanks 3 according to the specific pest control needs.

[0026] S2. Secure multiple medicine boxes 3 to the outer periphery of the trunk of the walnut tree using hook and loop fasteners 1 and binding straps (not shown). The hook and loop fasteners 1 pass through the sleeve plate 2 on the back of the medicine box 3, and the binding straps are tied from the outer periphery of the multiple medicine boxes 3. With both fixing methods, the medicine boxes 3 can be securely fixed to the trunk. When binding the straps, it is necessary to avoid the fan blade 42 to prevent the fan blade 42 from being blown by the wind.

[0027] S3. Apply insect-sticking glue to the outer surface of hook and loop tape 1. When pests climb up the tree trunk to hook and loop tape 1, they can be stuck by the insect-sticking glue. Multiple hook and loop tapes 1 can be set up side by side, which can improve the fixing effect of the pesticide box 3 and also provide multi-level insect prevention at different heights on the tree trunk.

[0028] S4. Insecticide seeps from the bottom of the pesticide tank 3, dripping onto the area around the base of the tree trunk, forming a ring of insect-repelling zone. When the wind blows, the insecticide droplets are dispersed. Specifically, a spraying assembly is installed at the bottom of the pesticide tank 3. This assembly includes a rotating cylinder 44 mounted at the bottom of the pesticide tank 3 and fan blades 45 located at the bottom of the rotating cylinder 44. The rotating cylinder 44 has an upward-opening flow channel that connects to the pesticide tank 3. Multiple evenly distributed seepage holes 441 are located on the side of the rotating cylinder 44. The insecticide flows downward through the flow channel to the seepage holes and drips outward through them. When the wind blows, the insecticide droplets are either directly dispersed by the wind, dispersed by the rotating fan blades 45, or dispersed when they drip onto the fan blades 45. Fan blade 45 disperses the insecticide. Considering that the insecticide drips slowly from the pesticide tank 3, it may gradually separate into layers, resulting in different concentrations of the pesticide at different heights. Therefore, a stirring component is installed on the side of the pesticide tank. When the wind blows, the stirring component agitates the insecticide in the pesticide tank. The stirring component specifically includes a rotating shaft 41 that is installed through and sealed on the side of the pesticide tank 3, and fan blade 42 and stirring blade 43 respectively installed on both sides of the rotating shaft 41. Fan blade 42 is located on the outside of the pesticide tank 3, and stirring blade 43 is located on the inside of the pesticide tank 3. When the wind blows the fan blade 42, the fan blade 42 drives the stirring blade 43 to rotate through the rotating shaft 41. The stirring blade 43 agitates the insecticide in the pesticide tank 3, improving the uniformity of the insecticide concentration.

[0029] S5. Observe the remaining amount of insecticide inside the pesticide box 3 through the transparent window 32. When the insecticide is insufficient, open the plug 31 on the pesticide box 3 and replenish the insecticide in time. The transparent window 32 can be designed with scale lines to make it easy to quantitatively control the remaining amount of insecticide and to add insecticide as needed, so as to prevent the application of excessive insecticide from affecting the growth of walnut trees.

[0030] S6. Use agricultural drones to spray insecticide from above the hickory trees downwards. Fill the agricultural drone's tank with insecticide in advance, set the drone's flight altitude and speed, and spray the insecticide on the upper branches and leaves of the hickory trees to further improve the pest and disease control effect.

[0031] In addition, during winter, it is necessary to remove diseased branches, leaves, and fruits from walnut trees and burn them to prevent the spread of pests and diseases in the walnut trees.

[0032] This embodiment achieves continuous pest and disease control through an automatic dripping insecticide dispenser (3). The insecticide, under its own gravity, seeps out from the seepage hole 441 and drips downwards, forming an insect-control zone around the base of the walnut tree trunk, preventing insects from climbing the tree. This provides long-lasting and effective pest and disease control. When the wind blows the spraying assembly, the insecticide enters the rotating drum 44 through the dispenser 3 and is discharged through the seepage hole 441. The centrifugal force of the rotating drum 44 propels the insecticide out, and the fan blades 45 further disperse and disperse the insecticide falling onto them, expanding the control area. Personnel only need to add insecticide to the dispenser 3; manual spraying is unnecessary, saving energy.
