What should I do if there are dry pests in the fruit trees? Once this pest occurs, the upper part will die or even die from the base, causing serious damage. Only by effectively preventing and controlling the pests, can the tree be robust, productive, stable, and high-quality. Now let's take a look at the prevention and control methods of dry pests.
First, the symptoms
Dry pests generally use larvae to live in the branches for food hazards. When trees are lightly damaged, nutrients and water transport are hindered, and severe branches are eaten into riddled holes, so that they die or are blown by the wind.
Second, prevention and treatment methods
1, trunk injection infusion method
At a height of 1.5-1.7 meters from the surface, a drip needle containing 0.3% azadirachtin 10-15 times solution is inserted into the subcutaneous layer, and the azadirachtin is channeled to various parts of the tree by the flow of the sap. Kill pests in the tree.
2, trunk punch injection method
When fresh sawdust is found in the wormhole, it indicates that there are larvae in the wormhole. You can use the cotton ball 蘸50% dibromophosphorus emulsifiable liquid to be inserted into the cleaned septic hole and sealed with wet mud to avoid the evaporation of the liquid. Off, the control effect can reach more than 98%.
3. Root embedding method
Open an annular groove at a distance of 0.5 to 1.5 m from the tree, or excavate 2 to 3 holes, and dilute it with 100 times solution with tree worm or aphid, and directly seal the soil after watering. It can effectively control the dry pests such as the beetle, and the efficacy can last for about 2 months.
The symptoms and prevention methods of the dried pests are finished. I don’t know if the growers have learned it. Everyone must do a good job in controlling pests and diseases when planting fruit trees.
