When it is wet, there is sparse white mold. This is the disease (cyst) Terrier and sporangia). The disease developed further and eventually the fruit quickly rotted. The mycelium or oospores are overwintered in the soil or in the manure with the diseased residue, and sporangia are produced in the following year by air, rain or irrigation water. Although the seed can carry bacteria, the carrier rate is not high. When the humidity is high, sporangia and zoospores are produced on the lesions for reinfection. The onset temperature range is 5 - 37 ° C and the optimum temperature is 20-30 ° C. The rainy season and high temperature and high humidity are rapidly onset.

Control method: After using resistant varieties, seed dressing with new high-fat film (can be mixed with seed coating agent or pesticide), moisturizing and heat preservation, and avoiding underground pests. Isolation of viral infection, enhanced germination and swelling, and improved seed germination rate. Choose well-drained fields, use deep ditch high-cabin or high-ridge planting, timely drainage after rain, and use the new high-fat film 600-800 times liquid to spray the soil surface after underground seeding to protect the water-proof evaporation, sun-proof and drought-resistant, heat-preserving and anti-freezing, isolation The source of pests and diseases is eliminated by suffocation, and the seed emergence rate is increased.
