Integrated disease management approaches for control of late blight of potato and enhancing the growth of potato
Experiments were conducted to study integrated approach in the management of potato blight. The result showed that T1 treatment (soil application of FYM @ 125gm/pot + waste of mushroom cultivation with Trichoderma harzianum @ 5gm/kg + tuber treatment with Azotobacter @ 5% + foliar spray with Ridomil @ 0.25%) was the best to show minimum disease severity, representing 9.16% as against 76.40% in case of control at 21 days of observation. The treatment also exhibited increased tuber germination and plant height of potato showing the value 100 per cent and 44.5 cm at 30 days age of plant. The maximum number of large size tuber and total yield with 668.6g was also recorded from treatment T1. Thus, integration of FYM + mushroom waste as soil application + bio formulation as tuber treatment + fungicides as foliar spray can be efficiently applied for management of late blight and also get enhanced yield of potato.
