广东甘蔗主要线虫病发生及防治研究

Study on the Occurrence and Control of the Most Important Nematode of Sugarcane in Guangdong Province of China

广东甘蔗以根结线虫病（Meloidogyneincognita）和矮化线虫病（Tylenchorhynchusspp.）为主．根结线虫病在砂土，特别是紧砂土田发生严重；矮化线虫则在壤土田发生严重．通过改良土壤，增施有机肥和施用杀线剂等综合治理措施收到显著的防病增产效果。

Root -knot nematode disease (Meloidogyne incognita)and stunt nematode diseaes (Tylenchorhynchus spp. )are the most important two nematode diseases of sugarcane on Guangdong.The former occurs severely in sand soil,while the latter is severe in loam soil. Soil improvement, as well as utilizing organic fertilizer and application of nematocide to the diseased area as a Integrated Pest Management measure has obtained very significant control effect and yield increase of the sugarcane crop.
