Diseases and pests

    Diseases
    The plant is susceptible to powdery mildew caused by Oidium spp., seedling blight caused by Rhizoctonia solani and roor-rot caused by Rhizoctonia bataticola. Powdery mildew can be controlled by spraying wettable sulphur (4 g/I of water), and the latter two diseases are managed by improved phyto-sanitary measures and by drenching the nursery-beds with a solution of mercurial fungicide.

    Pests
    Among the insects, the larvae of leaf-rollers sticking to the under surface of the leaves fold them backwards lengthwise, thus webbing them. Malathion (0.2%) may be sprayed to control this insect.
