1. The occurrence of this disease is commonly observed in corn-growing regions, with up to 20% or more of the planted varieties being affected in susceptible areas. Symptoms typically appear around the time of maturity. When hot weather is followed by sudden heavy rainfall and there is a significant temperature difference between day and night, the disease tends to reoccur. In late-maturing corn varieties, early infections often occur at the root and stem base. Symptoms usually become visible during the late filling and milk stages, with the entire plant wilting and lying on the ground, while the leaves turn blue, dry, and show signs of contraction. 2. Control measures include: (1) Selecting resistant corn varieties and sowing them at the right time, along with applying adequate potassium fertilizer to enhance plant resistance. (2) Implementing physical control methods such as removing water from the field promptly to avoid waterlogging, which can lead to poor ventilation and reduced root respiration, increasing the risk of infection. (3) For chemical control, when the infection rate reaches 10% or the disease index reaches 8, it is recommended to use 80% triadimefon wettable powder or 50% carbendazim wettable powder diluted 500 times. Apply the solution directly to the roots, using approximately 0.1 kg of liquid per plant. Regular monitoring and timely intervention are essential to prevent widespread damage and ensure healthy crop development.
