Peaches are one of the most popular fruit products in the world and are abundantly found in many regions. But as with other agricultural products, peaches also face diseases. In this article, we have investigated common peach diseases and their control and prevention methods.

بیماری‌های قارچی
عفونت پوسیدگی گردابی
This disease causes spiral rot of peach fruit. Its symptoms include brown spots on the fruit, secretions on it. To prevent this disease, use healthy and modified seeds, maintain sufficient distance between peach trees, and collect and bury rotten fruits.

پوسیدگی ریشه

To control and prevent this disease, use healthy and modified seeds and choose a new location away from the previous location of the peach plant.

سفیدک پودری هلو و شلیل :
Superficial powdery mildew or peach felt powdery mildew was first reported in Iran around Tehran in 1326 by Esfandiari. Diseases are usually seen wherever peaches are grown. In addition to peaches, it also attacks nectarines. The causative agent of the disease is Sphaerotheca pannosa var. Persica is The reason why it is named Panoza is due to the production of felt. The fungus is an obligate parasite and cannot be grown on the culture medium. This fungus spends the winter in two forms: budding thread and cleistothecium.
The symptoms of the disease on the leaves are initially pale green or brownish spots and finally the formation of felt texture. Old leaves are rarely attacked by the fungus and are resistant. The damage caused by the disease when it attacks the fruit is extremely high because the value and marketability of the fruit are significantly reduced. There are round spots on the fruit. If the fruit is green, the spot is white, and if the fruit is red, the yellow spot looks purulent. The stained parts of the fruit become hard and stop from normal growth. The branches affected by the fungus remain narrow and weak and their buds shrink.
کنترل بیماری:
Mechanical control: spraying, rain, hot and cold water, removing the felt membrane is among the measures that are effective in reducing the disease.
Biological control: the fungus that causes the disease in humid areas is parasitized by a number of hyperparasitic fungi, the most important of which is Cicinobolus cesatii, and they disappear or at least decrease.
Agricultural control: maintaining soil fertility, pruning and resistant varieties (velvet peaches, Cardi and Haj Kazemi are susceptible to diseases and fall varieties are resistant.)
Recommendations: The best time to spray is after falling petals and fruit formation. If necessary, spraying is done 3-7 times. The first time of spraying is important, and subsequent sprayings are done at intervals of 10 days.
