Abstract
2015 was a serious rice blast occurrence year in Xiajiang County. The occurrence area, occurrence degree, and yield loss were nearly the most serious in 25 years. The main causes were analyzed as follows:The main cultivated varieties were low resistance;the summer of 2015 was the coolest summer since 2000; From late May to early and midJune, from late August to early and midSeptember, it appeared continuous low temperature and abundant rains, and scant light; unsuitable cultivation and management; and low control effects. Therefore, as for the prevention and treatment strategies, resistant varieties should be selected, and the rice blast fungus races changes be timely grasped, the resistant varieties breeding and cultivar replacement be speeded up, and the monitoring and early warning be strengthened. Besides, according to the dynamic field status quo of rice blast outbreak, the crop rational layout should be guided to help farmers carry out prevention and control in a timely manner; scientific and rational drug use should be demonstrated to promote prevention and control against rice disease and insect pest damage so as to improve the control effects.关键词
