Symptoms: The disease mainly occurs in the ear damaged by mechanical damage, pests, or birds, and produces blue-green or green-brown moldy material on the grain or between grains, which often occurs at the tip of the ear. The germs invade the embryo, and when the seeds germinate, they cause the withering of the seedlings.
Control methods: (1) Use healthy and disease-free seeds. (2) Avoid wounds as much as possible, and take care to prevent bird damage. (3) Spray 70% thiophanate-methyl ultra wettable powder 1000 times solution or 50% benomyl wettable powder 1500 times, 40% carbendazim suspension 600 times, 50% methyl, if necessary. Thiophane WP 500-l000 times, 45% Tec multi suspension 3000-4000 times, control efficacy against Penicillium significantly.
