Pests and diseases

    Pests
    Nematode: Root knot appears as galls of various sizes, covering the root system. Application of 25 kg of 3G carbofuran or 20kg of 10G phorate granules per hectare will control the nematode.
    Pyralid caterpillar: It feeds on tender leaves, causing defoliation of the plant. It can be controlled by spraying 0.2% Rogar.
    Grub: Attacks the seedlings about 2cm below the hypocotyl resulting in their drying up. To control the attack of grubs, mix phorate granules with the soil at the time of nursery preparation.

    Diseases
    Leaf spot: Dark brown coloured spots on the upper surface of the leaves and yellowish brown on the lower surface. Spray Mancozb @ 0.2%.
    The other diseases are mosaic and die back.
