- Root rot disease occurs due to sudden drop and rise in temperature. Fungal disease develops in the soil causing the potato crop to turn black, which deprives the plants of the necessary nutrients and the plants turn yellow and wither away.
- Stem rot disease is a soil borne disease, in this disease, the stem of the potato plant turns black and gummy secretion comes out from the middle part of the stem due to which the main nutrients do not reach the upper part of the plant and the plant dies
- For prevention of these disease use Azoxystrobin 11% + Tebuconazole 18.3% SC@ 300 ml/acre or Kasugamycin 5% + Copper Oxychloride 45% WP@ 300 gram/acre or Chlorothalonil 75% WP@ 400 gram/acre or Thiophanate Methyl 70% W/W@ 300 gram/acre
- As biological treatment use Trichoderma Viride@500 gram/acre or Pseudomonas Fluorescens@ 250 gram/acre
