Pistachio diseases are different, which we will pistachio shell examine in the following 6 important diseases. One of the diseases affecting pistachio trees is Gamoz-iodine disease, also known as Angomek. The disease is more common in gardens with heavy or semi-heavy soil texture.
The disease, which appears as a dry green, quickly causes complete dryness or death of the tree. Several trees in a row may be affected by the disease. Gum disease can affect the tree at any age, so the age of the tree is no different for gum disease. But pistachio trees have different resistance to gum disease with age. For example, the resistance of young trees is less than that of old trees against gum disease.
Trees with crowns under the ground are more prone to gum disease because water seeps into the crowns of these trees and causes fungus. The causative agent of gum disease in pistachio trees is fungi Fetti.
The symptoms of gum disease are as follows:
Dry green of trees
Falling leaves of trees in a season when there is no leaf fall.
Weakening of trees
Blossoming of trees
Discoloration of the bark of trees and in the crown area is accompanied by the secretion of drops of black gum.
The control of gum disease is as follows:
The soil around the crown of the tree should be removed (up to the branch of the main roots)
Water contact with the crown of the tree should be avoided.
Improving the soil texture of orchards infected with gum disease, which should use lighter soil texture.
