Fungicides from the main diseases of pomegranate in the western zone of Azerbaijan

Abstract

Diseases of fruit crops cause great harm to horticulture - the yield is significantly reduced and its quality deteriorates, the plants weaken and become susceptible to various adverse conditions, which often leads to their death. Pomegranate scab (Sphaceloma punicae Bitank. Et Jenk.) sharply reduces the yield and quality of fruits, zithiasis fruit rot (Zythia versoniana Sacc.), which has spread widely in recent years, affects flowers, fruits, stalks, leaves, branches, trunk and root collar, which greatly weakens the tree, reduces its yield and resistance to frost. Damage to fruits by scab or anthracnose in some years reaches 40-50% or more. A comparative analysis of the field assessment of the biological effectiveness of the applied fungicides in the fight against pomegranate scab in a fruit-bearing garden was carried out. The biological assessment of fungicides was carried out in 2019 and 2020 as already noted in the fruit garden. The study of the preparations was carried out in field conditions, optimal for growing a culture, against a natural infectious background. The plot is homogeneous in fertility, mechanical composition of the soil, relief, planting pattern, crown formation, with the same n utritional area, age and fruiting strength. Trees that were old and damaged by frost, cancers and rodents were excluded.
