| Abstract: | In this article,the rice blast occurrence data from 2010 to 2019 of the main counties(city,district)in Guangdong were collected and analyzed.Taking into account the location and the size of the rice blast occurrence area as well as the rice planting area,we defined the classes of the occurrence of rice blast and determined its geographic distribution on a map.The results indicated that the main rice blast occurrence areas were concentrated in the north of Guangdong province.There were some scattered occurrence areas in the west of Guangdong such as Zhanjiang,Maoming,Yangjiang,Yunfu,etc.The sporadic areas were mainly in the east of Guangdong,Zhujiang river delta,and part of western Guangdong. |
