First, the characteristics of the disease: the pathogen is a semi-known fungus Alternaria spp. The suitable temperature for pathogenic bacteria development is 26~28°C, with rapid infection and short incubation period. Mycelia and mycelia are attached to the diseased body or the seeds are overwintering. High temperature, high humidity, and field condensation are conducive to disease. The disease started from the old leaves in the lower part of the plant and gradually developed upwards. Large temperature difference between day and night, continuous rain, poor ventilation and drainage, plant growth decline, etc., is the main reason for the occurrence and prevalence of the disease.
Second, the prevention and treatment methods: commonly used Shijiale 40% suspension agent 1000 ~ 1500 times liquid, or 50% acetaminophen suspension or WP 1000 times evenly spray.
