Part of the selected text from within the PowerPoint file:

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

بيماري‌هاي قارچي
عفونت پوسيدگي گردابي
This disease causes the rotting of peach fruit. Its symptoms include brown spots on the fruit and secretions on it. To prevent this disease, use healthy and modified seeds, maintain sufficient distance between peach trees, and collect and bury rotten fruits.

پوسيدگي ريشه
This disease causes rotting of the peach plant root and its symptoms include brown spots near the root and complete death of the plant. Also, plants affected by this disease are quickly transferred to other new plants. 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.

پوسيدگي ميوه
This disease causes rotting of peach fruit and its symptoms include brown spots on the fruit and secretions on it. To prevent this disease, use healthy and improved seeds, collect and bury rotten products, and avoid using excessive fertilizers and direct sunlight for fruits.

سفیدك پودری هلو و شلیل :
Superficial powdery mildew or peach felt powdery mildew was reported for the first time 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 culture medium. This fungus spends the winter in two forms: a budding thread and a cleistothecium.
Symptoms of the disease on the leaves are initially pale green or brownish spots and finally the formation of felt tissue. 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 is significantly reduced. The spots on the fruit are round. If the fruit is green, a white spot appears, and if the fruit is red, the yellow spot appears purulent. The spotted parts of the fruit become hard and stop from normal growth. The branches affected by the fungus remain narrow and weak and their buds become small.
كنترل بیماری:
Mechanical control: sprinkling, 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 are at least reduced.
Agricultural control: maintaining soil fertility, pruning and resistant varieties (velvet peach, Cardi and Haj Kazemi varieties are sensitive to the disease and fall varieties are resistant.)
Recommendations: The best time to spray is after the petals fall 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.
