It is affected by Downy mildew disease incited by Pseudoperonospora cubensis (Berk. & Curt.) Rostow. every year. The disease appears in December and continues up to the end of March. It causes drying up of leaves in growth stage of the crop. Spraying of Krilaxyl Gold (Metalaxyl 8% WP + Mancozeb 64% WP), Blitox (Copper Oxy-chloride 50% WP) and Indofil M-45 (Mancozeb 75% WP) recorded better and gave good protection against downy mildew in pointed gourd. Spraying should be done just before sunset. Retarded growth of vine of pointed gourd was noticed due to spraying of Contaf (Hexaconazole 5% EC) and Tilt (Propiconazole 25% EC).
