摘要
Abstract
Top rot of corn is a systemic infectious diseases. Seeds, soil and plant debris are the primary infection sources. Varieties lack resistance and poor tillage managements are the main causes. Secondary infection occurs in the young leaves of susceptible varieties before or after heading, but it will not affect plant growth and yield. Varieties with high resistance, improvement of cultivation technology and application of chemical pesticides seem to prevent the prevalence or control the damage of this disease.关键词
