Repeat control measures for early blight disease to save crop from infestation. Apply irrigation to crop at 2-3 days interval if frost appears to save crop from frost damage.
Aphids (Myzus persicae)
Aphids suck the sap from leaves. Affected plants become weak; leaves become yellow and curl downwards. Aphid secretes honeydew, which gives rise to sooty mould and other fungal diseases.
Control Measures-
1. Spray the crop with rogor or metasystox or nuvacron or monocil at 1 ml per liter of water, and repeat the spray 10 to 12 days interval
2. Apply thimate 10 G granules at 10 kg per hectare in furrows at the time of planting.
3. Cut the haulms in the first week of January to check the transmission of virus through seed potatoes.
