Popular varieties

Variety selection depends on cropping season, soil type, and target market. Hybrid varieties generally produce higher and more uniform yields. Open pollinated varieties have lower seed cost.

Open Pollinated

Green straight fruits, good yield, widely adaptable across North and South India

Kashi Kalyani

Open Pollinated

Dark green uniform fruits, preferred in wholesale markets, suitable for UP and Delhi

Kashi Shreya

Open Pollinated

Dark green straight fruits, resistant to mosaic and downy mildew, suited for Kharif season

Kashi Rakshita

Hybrid

High yield potential, extended fruiting period, suitable for commercial markets

Kashi Saumya

Hybrid

Tolerant to multiple diseases, suitable for river bed cultivation in Uttar Pradesh

Kashi Divya

Key challenges

Common pests, diseases, and management issues in sponge gourd cultivation. Early identification and timely management help reduce crop loss.

Fruit fly

Maggots infest fruit internally causing premature dropping and making fruit unmarketable. Collect and destroy infested fruits. Use attractants such as citronella or eucalyptus oil to trap adults. Monitor the field every 3 to 4 days from 30–35 days after sowing.

Powdery mildew

White powdery spots form on leaf surfaces and expand into large blotches; infected plants produce fewer and smaller fruits. Apply Wettable Sulphur 0.2% or Propiconazole 25% EC at first sign of infection.

Downy mildew

Yellow to pale green spots on the upper leaf surface with velvety fuzz underneath; leaves dry up quickly if untreated. Use drip irrigation instead of overhead sprinklers. Apply Mancozeb 2 gm per litre of water.

Aphids

Twisted and curled leaves, yellowing, and stunted growth. Spray Imidacloprid 0.5 ml per litre of water. Remove heavily infested plant parts and apply neem oil as a preventive measure.

Waterlogging

Though more tolerant than other cucurbits, the crop performs best on well-drained raised beds, particularly during Kharif season.
