In recent years, with an increase in the area under pomegranate and an increase in its yield, the likelihood of the spread of harmful mycoses (fungal diseases) has significantly increased. Cercosporosis (Cercospora lythracearum Heald et Wolf) occupies a special place among the widespread diseases in pomegranate gardens. The harmfulness of cercosporosis in pomegranate in the conditions of the western part of Azerbaijan is manifested in the damage to the leaves and fruits and in the decrease in the assimilation surface of leaves and the mass of fruits, which negatively affects the yield. The cercosporosis leads to a decrease in the annual growth of shoots by 1.2 times and to a decrease in fruit weight by an average of 15%. In connection with the above, the task of our research was to study and diagnose the cercosporosis of pomegranate bushes in the conditions of the western part of Azerbaijan. In the 2020 research year, an assessment of the prevalence and intensity of cercosporosis in the region was carried out, and a scientifically based and improved control system was developed. For this purpose, the following products were tested in the fight against cercosporosis: 0.4% Selfat, 0.3% P-oxyride, 0.05% Conazole, 0.05% Azoxifen and control without chemical treatment. The data on the effectiveness of the fungicide 0.4% Selfat against pomegranate cercosporosis are presented. Three-fold application of the drug with a consumption rate of 5 kg/ha in the pomegranate protection system provided fruits that were free from cercospora spots. |
