Management of Early Blight
It is difficult to secure a good control of early blight and leaf spots. The following steps can help in reducing incidence of these leaf spots:
1.
The crop must be given a balanced dose of fertilizers, especially
nitrogen.
2.
The crop sprayed with 1.0% urea at 45 days and given one additional spray
after 8-10 days may easily escape the severe onslaught of early blight and leaf
spots.
3.
Fungicidal sprays are effective in controlling early blight and other
leaf spots. In hills, copper
fungicides including Bordeaux mixture (1.0%) and copper oxychloride (0.3%),
recommended for control of late blight, can take care of early blight and leaf
spots.
4.
Cultivation of Solanaceous
crops, being collateral hosts in nearby potato fields must be avoided.
