Corn top rot is an important disease of corn. China was first discovered in Fuxin, Liaoning Province in 1998 and it is a new disease of corn. In 2002, top rot occurred in the corn producing areas in Liaoning Province, which caused serious production losses. Prevention technology is as follows: 1. Implement rotation to avoid continuous production as much as possible. After the harvest, we should clean the garden in time and properly treat the diseased plants to reduce the source of bacteria. 2, selection of disease-resistant varieties, with seed coating agent and new high fat film seed dressing, can repel underground pests, isolate virus infection, does not affect the germination and swelling function, enhance respiratory intensity, improve seed germination rate. Appropriate sowing, reasonable close planting. 3, to strengthen field management, the use of sorghum cultivation, flood irrigation is prohibited, timely drainage after the rain to prevent moisture retention. Rational fertilization, pay attention to the proportion of NPK equilibrium. Spraying a strong earring at the booting stage can strengthen the physiology of crops, improve pollination and grouting quality, and increase grain weight. 4, pharmaceutical control. Do a good job of monitoring the disease, early onset of carbendazim (or chlorothalonil, or mancozeb) plus a new high-fat film, watered leaf spray.
