In Iran, the damping-off disease of summer crops is known by the local names of dry green, scorching, and water-affected, and is a major disease of cucumbers, melons, watermelons, and pumpkins. This disease has been prevalent in all cultivation areas of these plants, including Khuzestan, Isfahan, Fars, Kerman, Jiroft, Tehran, Varamin, Saveh, Kashan, Lorestan, Qazvin, Hamadan, Khorasan, Bandar Abbas, Azerbaijan, and Mazandaran. Agricultural, chemical, and biological control methods are applied in the management of cucumber damping off. In general, a review of the research showed that the use of chemical and biological pesticides is a very suitable solution to control plant rot, because if it is not controlled in time, it can destroy the entire crop and cause irreparable damage to the greenhouse or farm owner.
