| Abstract: | Based on investigations of the characteristics of main paddy rice diseases and their trends in different years in Taojiang county of Hunan province,the optimal techniques for the control of large scale rice diseases in paddy field,i.e. county based prevention,town ship based control,field based application and counter measures based on the characteristics of main paddy rice diseases,were obtained between 1997 and 1999.Several types of pesticides with characteristics of low residue,high effect and protection of natural enemy were also obtained.These techniques reduce control cost by 21.31% and increase yield by 440 kg/hm 2,compared with the traditional methods of control |
