Abstract

A disease survey in rattan nurseries, plantations and natural stands in Kerala State, India, revealed that Calamus dransfieldii, C. gamblei, C. hookerianus, C. pseudotenuis, C. rotang, C. thwaitesii, C. travancoricus and C. vattayila are susceptible to various fungal pathogens in different growth phases. In nurseries, seedlings are affected with diseases caused by Bipolaris ellisii, Colletotrichum gloeosporioides, Corynespora cassiicola, Fusarium longipes, Guignardia calami, Sclerotium rolfsii and Rhizoctonia solani. Of these, seedling blight caused by Guignardia calami and seedling collar rot caused by Fusarium longipes are the most important diseases. In plantations and natural stands, rattans are affected by various foliage pathogens, such as Bipolaris ellisii, Colletotrichum crassipes, Colletotrichum gloeosporioides, Glomerella cingulata, Pestalotiopsis theae, Phomopsis palmicola, Phyllachora calamigena and Sphaerodothis. Among these, Colletotrichum infection on unopened spear (frond) and Sphaerodothis foliage blight caused severe damage to young as well as mature plants. Stem rot and staining, caused by Pellicularia filamentosa and Botryodiplodia theobromae, respectively, are the other important diseases. Nursery diseases can be effectively controlled by application of fungicides, viz., carboxin, mancozeb, carbendazim by seed dressing, soil drenching or by foliar spraying.

印度喀拉拉邦苗圃、人工林和天然林分藤病的研究

通过对印度喀拉拉邦藤苗圃、人工林和天然林分的病害调查，发现在不同生长阶段，dransfieldii、C. gamblei、C. hookerianus、C. pseudotenuis、C. rotang、C. thwaitesii、C. tranancoricus和C. vattayila对多种真菌病原体易感。在苗圃中，幼苗受到两极线虫、gloeosporioides、cassiicola、Fusarium longipes、Guignardia calami、Sclerotium rolfsii和Rhizoctonia solani引起的疾病的影响。其中，猪瘟病菌和长镰刀菌引起的幼苗枯萎病是最重要的病害。在人工林和天然林分中，藤本植物受到多种叶片病原菌的影响，如双星病菌、葡萄炭疽病菌、gloeosporioides炭疽病菌、带状小球病菌、拟盘多毛孢病菌、棕榈多毛孢病菌、菖蒲Phyllachora calamigena病菌和Sphaerodothis病菌。其中，炭疽菌侵染未开封的矛(叶)和球孢叶枯病对幼苗和成熟植株均造成严重危害。茎腐病(Pellicularia filamentosa)和茎染病(Botryodiplodia theobromae)是另外两种重要病害。苗圃病害可以通过施用杀菌剂，如碳毒素、代森锰锌、多菌灵等，通过撒种、淋土或叶面喷洒来有效控制。
