The participants witnessed the trial of new pesticides developed by Zhenjiang Agricultural Science Research Institute on the prevention and control of coccidiosis diseases and discussed the occurrence, control and resistance of rice bacterial diarrhea in the province. It is understood that rice Bakanae disease in Jiangsu Province, rice production in multiple, the incidence of field generally reduced by 10% to 20%, severe disease can be reduced by more than 50%. The existing active ingredient of rice seed leaching agent is prochloraz, long-term use of prochloraz antibiotic soaking rice seedlings disease prevention, leading to bacteria resistance to prochloraz increasing,
