Tomato crops powdery mildews in the western part of Azerbaijan and measures to combat it

In the western part of Azerbaijan, tomato plants currently make up half of the open and covered fields. In recent years, the range and damage possibilities of fungi, which were rarely encountered before and were not characterized by high damage, have expanded in the tomato plant belonging to the Solanaceae family. The route and stationary observation-calculation works conducted in the western part of Azerbaijan showed that numerous pathogens are spread in tomato crops. Among these diseases, it has been determined that powdery mildew disease, which was not of economic importance before, prevails due to its spread and damage to crops. A fungicide trial was conducted against the disease.
