Efficacy of bioagents and botanicals on seed mycoflora and seed quality in mungbean [<italic>Vigna radiata</italic> (L.) Wiczek

Abstract

Seeds of mungbean (Cv. Vaibhav) was treated with bioagents and botanicals <italic>viz;</italic> talc powder formulations of <italic>Pseudomonas fluorescens</italic> (0.6%), <italic>Trichoderma viride</italic> (0.6%), <italic>Pseudomonas fluorescens + Trichoderma viride</italic> (0.6%) each, garlic extract (1%), ginger extract (1%) and Thiram + Carbendazim (0.2% each) as a recommended fungicidal check. The results indicated that, among the bioagents the treatment of <italic>Pseudomonas fluorescens + Trichoderma viride</italic> (0.6% each) to the seeds of mungbean was effective in reducing seed mycoflora <italic>viz; Fusarium oxysporum, Alternaria alternata, Macrophomina phaseolena</italic>, <italic>Aspergillus flavus, Aspergillus niger</italic> and <italic>Fusarium moniliforme</italic> by 88.5, 85.1, 64.9, 81.1, 75.0 and 100 per cent, respectively over untreated control. The seed germination, seedling vigour index and field emergence of mungbean was increased by 21.81, 34.03 and 15.98 per cent, respectively with this treatment over untreated control. The seed germination, seedling vigour index and field emergence in untreated control was 71.83 per cent, 2261.52 and 67.83 per cent, respectively.
