Abstract. Gardeners started cultivating wild blueberries only 100 years ago, so we can safely say that blueberries are a young culture. This berry is attractive both as an ornamental plant and as a berry shrub, which gives a high-quality, delicious, vitamin-rich harvest. The berry is used in pharmaceuticals, as blueberries contain powerful antioxidants and a high amount of vitamins.
Keywords: blueberry, plant protection, chandler, bluecrop, bluegold, duke.
The object and methodology of the study. Chandler. The garden variety of blueberry Chandler is a perennial deciduous plant of late fruiting period. It belongs to tall varieties; the height of adult blueberries is 1.5-1.7 m. The shrub is spreading, branched, the crown diameter is 1.5 m. Chandler blueberries with a high degree of frost resistance, without damaging the stems and root system, resists temperature drops to -250 C.
Fig. 1. A bush of the Chandler blueberry variety The flowers are lily-shaped, small. The buds are pink, and after blooming they are white, drooping. Flowering is abundant.
Fruit brushes are formed on last year's shoots, the density is from 8 to 12 berries, located on the outer part of the bush.
The high yield of the Chandler variety is ensured by late flowering, it falls in June, frosts at this time are rare even in the Northern regions. The berries ripen unevenly, the harvest continues from August to September. If they do not have time to harvest part of the crop before the first frosts, blueberries do not fall off, they completely retain their taste and shape.

Advantages of blueberries Chandler: stable long-term fruiting, high productivity, frost resistance, suitable for the northern climate, the weight, taste and juiciness of the berry, the fruits do not fall off and do not bake in the sun, the variety is self-fertile, the agricultural machinery is simple.
The disadvantages of the Chandler blueberry variety include poor drought resistance. With a lack of moisture, vegetation slows down, the yield and taste qualities of fruits fall. A common blueberry disease affecting young shoots and leaves is the spread of the Phomopsis fungus. Infected areas of the stem dry out, the leaves turn yellow and fall off. "Topsin" is used in the fight against infection. For prevention purposes, blueberries are treated in spring with a solution of copper sulfate and potassium hydroxide. The beetle khrushch and leaf beetle parasitize on the Chandler variety, eliminate pests with "Inta-Vir" and "Spark".
Materials and methods of research. Blueberries contain many biologically active substances necessary for human health. It has been proven that regular consumption of blueberries and blueberries reduces the "fatigue" of the eyes when reading books for a long time or being at the monitor. At the same time, subjective and objective symptoms improve. Japanese scientists also emphasize the effectiveness of the plant in order to prevent and treat diseases such as retinal detachment and age-related macular degeneration.

Agricultural technology of Chandler blueberries consists of frequent watering, fertilizing, pruning. It is also important to maintain the necessary soil acidity.
Form a bush of the Chandler variety for the 3rd year of growth, shorten the stems by 1/3 in early spring. Continue pruning until the age when the bush begins to bear fruit fully. Then, in
autumn, the middle is thinned, old, twisted branches are cut off. In spring, sanitary cleaning of dry
areas and frost-damaged stems is necessary.
Conclusion. Chandler blueberry is a high-yielding garden variety with a large berry.
The plant is highly frost-resistant, adapted to the weather conditions of the north and the
temperate climate zone. Fruits with high gastronomic characteristics, versatile in use. The
crop is grown to produce berries and as an element of landscape design.
