In Vivo Evaluation of Bioresources Against Late Blight of Potato Caused by Phytophthora infestans, Plant Growth and Yield of Potato (Solanum tuberosum L.)

Bassi Santosh, Kandhi Mounika and Sobita Simon

Potato (Solanum tuberosum L.) is a solanaceous crop which have an importance as both food and cash crop for many poor people and is considered as food security in developing countries. Important fungal diseases, which affect potato crop are late blight, early blight, black scurf, dry rots, wart, powdery scab, charcoal rots etc., A detailed experiment was conducted to study the efficacy of bioresources against late blight of potato (P. infestans). Among all the treatments T3 (VC+SMC+NK) reduced disease incidence (%), disease intensity (%), CODEX (%) followed by T5 (SMC+VC), T2 (VC), T6 (MA), T4 (SMC), T1 (NK), T0 (Control). Similarly, among treatments T3 (VC+SMC+NK) maximised yield (gm) & plant height (cm) followed by T5 (SMC+VC), T2 (VC), T6 (MA), T4 (SMC), T1 (NK) and T0 (Control).
