Rice is a staple food crop in Yingkou area of Liaoning Province and is also one of the main paddy producing areas in the province. In recent years, the disease resistance of rice plants has been gradually reduced. Rice panicle blast occurred in varying degrees each year, resulting in some yield reduction. Based on this, the characteristics and causes of rice blast were analyzed.
