In recent years, millet producing areas in our province generally suffer from the damage of the cereal blast, the affected millet generally cut 2-3 percent, a serious 5-7 into. The counties in Yanbei were the heaviest in all counties, and they were not only harmed by epidemics but also damaged by spikes, spikes and serious diseases. According to the survey, the area occurred in 1982, covering an area of 140,000 mu and losing 8 million kg of grain. In order to develop a measure to control the rice blast in the near future and speed up the development of agricultural production, based on the previous studies and combining with the occurrence of the rice blast in Lingqiu County in recent years, the occurrence and control measures of the rice blast Some discussion.
