distance of 100 x 50 cm and thinned out to get two plants per hill, ten days after planting. It is

better to apply straw mulch in the cultivation. Irrigation has to terminate two weeks prior to

Pest and Disease

Pest: Aulacaphora beetle, Leaf minor and Fruit fly are the major pest in melon.

Aulacaphora beetle Adults feed on leaves and the larvae damage the stem and root system. Apply Carbofuran 3%granules at planting to control larvae in areas where the damage is severe. For adults apply

Trichlorafon 50 EC (800-1100 ml/ha) or Carbaryl 45 WP (1.1-1.4 kg/ha) when the damage or

pest is observed.

Fruit fly Apply Fenthion 50 EC at the rate of 1050-1400 ml/ha at flowering. Bagging the fruits if possible

will also reduce the pest damage.

Leaf minor

It is not advisable to apply chemicals to control this pest. However if the pest damage severeapply Cyramaizine at the rate of 150 g/ha or Azadirachtin 400 ml/ha. Check for live mines in 6thto 12th leaves below the tip.

Diseases Powdery and Downey mildew, are the major diseases in melon. The powdery mildew on leaves

characterized by the appearance of tiny white to dirty gray spots on upper surface of the leaves

while angular yellow coloured spots appears on lower surface of the leaves when infected by theDowney mildew. Maintained the field without host plant and cucurbitacea plants. Apply Captan

Carbendazim or Thiophanate- methyl to control powdery mildew and apply Captan, Maneb or

Propineb as per instructions by the manufacture to control downy mildew.

Harvesting & Post-harvest Technology

Harvest Melon can be harvested 75-110 days after planting. Average yield is about 25-30 mt/ha. Melon

has to be harvested at the correct stage of the fruit maturity. Dark green skin, yellow colouredspot where the fruits touches the ground and watery sound when tapping are the indicators of



proper stage of maturity.
