Prevention of late blight disease in potato crop

It affects leaves, stems and tubers.
In this disease, irregularly shaped water-soaked spots are formed on the leaves, which causes the early fall of leaves. Due to these spots, a brown layer is formed on the leaves which affects the photosynthesis process of the plant.
As the process of photosynthesis is affected, the plants are unable to produce food, stunting the plant’s growth and the plant dries prematurely.
White growth develops under the surface of the leaves, on the stem and nodes, at these points, the stem breaks and the plant falls. In tubers, purplish-brown spots spread over the entire surface when cut, and rusty brown necrosis appears from the affected tuber surface to the centre.
Chemical Treatment:- Azoxystrobin 11% + Tebuconazole 18.3% SC @ 300 ml or Kasugamycin 5% + Copper Oxychloride 45% WP @ 300 g or Tebuconazole 10% + Sulfur 65% WG @ 500 g or Metalaxyl 4% + Mancozeb 64%WP @ Spray 600 gm or Tebuconazole 50% + Trifloxystrobin 25% wg @ 150 ml per acre.
Biological treatment:- Use Pseudomonas fluorescens @ 250 gm/acre.
