Efficacy of bioagents and fungicides against web blight of mung bean caused by Rhizoctonia solani (Kuhn)

Abstract

Efficacy of antagonists and fungicide were evaluated under in vitro conditions for the mycelial growth inhibition. It was observed that all the biocontrol agents were significantly superior in inhibiting the mycelial growth of test fungus over control. Mungbean (Vigna radiate L.) is an important pulse crop in Indian continent. Mungbean is infected by several fungal, bacterial and viral diseases but foliar blight caused by Rhizoctonia solani considered as one of the most devastating diseases in the mungbean. The main aim of this study was to find out the effective fungicides and bioagents for the timely management of R.solani. Efficacy of Fungicides with Concentrations Vitavax (0.03,0.05 and 0.1 %), Carbendazim (0.03,0.05 and 0.1 %), Mancozeb (0.03,0.05 and 0.2 %), Thiram (0.03,0.05 and 0.1 %), Antracol (0.03,0.05 and 0.1 %), Nativo (0.03,0.05 and 0.1 %), Azoxystrobin (0.03,0.05 and 0.1 %), Prism (0.03,0.05 and 0.1 %), Melody (0.03,0.05 and 0.1 %), and Conrol. Bioagents efficacy Trichoderma harzianum (Th1), Trichoderma harzianum (Th2), Trichoderma harzianum (Th3), Trichoderma harzianum (Th4), Trichoderma harzianum (Th5), Trichoderma harzianum (Th6), Trichoderma viride (Tv1), Trichoderma viride (Tv2), Trichoderma viride (Tv3), Trichoderma viride (Tv4), Trichoderma viride (Tv5), Trichoderma viride (Tv6) and Control.
