Abstract

In 2024, phytosanitary diagnostics were conducted in the gardens of the Almaty region to determine the spread and development of powdery mildew and scab. The study focused on apple trees grown in the gardens of the peasant farm SHK "Koram" in the village of Koram, Enbekshikazakh district. The area of the garden is 110 hectares. The varieties grown include Gala, Fuji, Golden Delicious, Quinty, Red Delicious, Divo, Korey, and Stark Earliest, with the age of the seedlings ranging from 2 to 5 years, and an average yield of 50 tons per hectare, totaling 5500 tons. As a result of the phytopathological assessment, scab infection was clearly visible on the leaves and fruits of the Gala, Golden Delicious, and Stark Earliest varieties. Powdery mildew was found on the Gala, Fuji, Golden Delicious, and Red Delicious varieties. In the gardens of the peasant farm SHK "Koram," the spread of scab ranged from 16 to 20%, while the development of the disease ranged from 0.43 to 1.27%. The spread of powdery mildew ranged from 1.9 to 30%, and the level of disease development remained low, ranging from 0.32 to 1.5%. These diseases cause significant damage to production horticulture, thus constant monitoring and expertise are necessary. Based on the results of the phytosanitary monitoring in 2024, the spread and development of scab and powdery mildew in the gardens is not critical.
