Camellia coal disease is the province of Camellia producing areas of devastating diseases. According to the statistics of some communes and brigades in Changshan, Kaihua and Jiangshan counties in 1973, the disease area reached more than 20,000 mu. Failure to control it in time would affect the development of the production of Camellia oleifera and increase the yield of camellia.

In the prevention and control, we must implement the principle of “cure early, cure small and cure” principle of “prevention first, eliminate actively”, and actively carry out mass pest control scientific experiment. Based on silviculture techniques, biological control should be vigorously promoted, chemical pesticides should be rationally used, soil pesticides should be actively tested, and comprehensive prevention and control measures should be taken according to local conditions in order to achieve the goal of economizing the oil and tea diseases economically and effectively. In order to exchange experience, now camellia coal
