Abstract/Description: | Wilt and pokka boeng (PB) caused by Fusarium Sacchari and F. verticilloides in sugarcane are considered to be minor diseases under Coimbatore conditions. However, during the 2009-10 season sudden outbreaks of these diseases appeared in National Hybridization Garden (NHG) where 608 sugarcane hybrid clones are maintained to perform hybridization. Detailed investigations were carried out on the associated pathogens, disease epidemiology, disease resistance in the clones and their management. During 5-6 months stage, initial symptoms of PB were noticed and gradually PB severity increased from chronic to acute phase along with top rot symptoms. As the days progressed affected canes exhibited wilting along with or without top rot symptoms. When the disease severity increased from resistant to susceptible, the affected clones exhibited combined infections of PB and wilt symptoms. Among the different phenotypes of PB and wilt in the clones, top rot and wilt caused more damages in the clones. However, some of the clones exhibited severe wilt alone with more crop loss and severe wilting caused extensive damages to some of the established varieties and parents. Fusaria isolated from the affected tissues were found to be pathogenic in artificial testing. The parental clones in the NHG exhibited a clear variation in their resistance to PB, top rot and wilt and the clones originated from the subtropical region except those from Uchani were found to have more resistant types as compared to those from the tropical states. Although the disease situation was precarious, it was successfully managed by an integrated approach involving chemicals and biocontrol agents in the subsequent seasons. Further studies are in progress to characterize the associated pathogens and their interrelationship in causing PB, top rot and wilt diseases in sugarcane. |
