The Reasons and Treatment for Apple Tree Leaf Curling
This article focuses on the green plant-related content of the reasons and treatment methods for apple tree leaf curling. Next, our site editor will introduce these to everyone.
The Reasons and Treatment for Apple Tree Leaf Curling
Apple tree leaf curling may be caused by improper maintenance, excessive or insufficient watering, insufficient or excessive sunlight, excessive fertilization, and diseases such as brown spot and leaf spot. Apple trees do not tolerate high temperatures, so temperature control is necessary in the summer. When cultivating, they should not be short of water, nor should they be waterlogged. During the growing period, it is necessary to spray pesticides to protect the leaves, and diseases such as brown spot and target leaf spot can be controlled with carbendazim or methytobuzin.
What Causes Apple Tree Leaf Curling?
Apple tree leaf curling may be caused by improper maintenance, excessive or insufficient watering, insufficient or excessive sunlight, excessive fertilization, and diseases such as brown spot and leaf spot.
The Reasons for Apple Tree Leaf Curling
Apple tree leaf curling may be caused by pests and diseases, calcium deficiency, or insufficient watering. Generally, leaf curling in apple trees is related to red spiders, and if the leaves are withered, attention should be paid to the use of nitrogen, phosphorus, and potassium.
Methods to Treat Apple Tree Leaf Curling and Wilting
1. Temperature: Apple trees do not like high temperatures. In the summer, it is necessary to control the temperature and sprinkle water to cool down, thus preventing leaf curling and wilting.
2. Watering: When cultivating apple trees, it is important not to let them lack water, nor should they be waterlogged. They should be watered promptly in dry conditions and drained promptly in times of heavy rain.
3. Fertilization: Apple trees require fertilization when planted intensively in orchards, but fertilization should not be excessive. If there is excessive fertilization, more watering should be done to dilute the nutrients.
4. Diseases: During the growing period, apple trees need to be sprayed with pesticides to protect the leaves. Brown spot and target leaf spot can be controlled with carbendazim or methytobuzin. Red spider pests can be sprayed with 2 emamectin benzoate emulsifier or pyridaben. For leaf-rolling moths, the old bark should be removed and destroyed during the dormant period, with pesticides mainly sprayed on the underside of the leaves.
