Practice of combating potato (Solanum tuberosum L.) disease in Azerbaijan on the example of phytophthora

Potatoes (Solanum tuberosum L.) are the fourth largest crop in the world after rice and corn. In Azerbaijan, the yield of potatoes per unit area is very low compared to other countries of the world. There are many factors that reduce crop productivity, among which diseases such as late blight of potato (Phytophthora infestans) play an important role. Therefore, the fight against this disease is very important. Late blight of potato can be controlled by the following control strategies: use of biological control agents, use of resistant varieties, crossbreeding, use of certified disease-free seeds, use of selective fungicides and agronomic practices such as destruction of cull heaps by freezing or deep burial, destruction sprouting voluntary potato plants in nearby fields during the season, killing infested plants to avoid spreading, shortening periods of leaf wetness and high canopy moisture through proper irrigation times, applying the recommended fungicide spraying program (program must be started before pathogen is detected).
