Urdbean (Vigna mungo L. Hepper) also known as mash or blackgram is important Kharif pulse.It suffers from many diseases in which anthracnose leaf spot caused by Colletotrichum truncatum (Schwein) Andrus and Moore occur in endemic form in high rainfall areas and result in qualitative and quantitative yield losses. The field experiments on integrated management of anthracnose revealed that among organic and natural inputs, three sprays of panchgavya (@10%) at ten days interval gave maximum disease control of 33.64 per cent with 26.14 per cent yield increase whereas crude extract of botanicals i.e. Melia azedarach (Darek), Eucalyptus sp. (eucalyptus), Eupatorium odoratum (Basuti) and Lantana camera (lantana) three foliar sprays of eucalyptus (@30%) at 10 days interval gave maximum disease control of 28.18 per cent with 21.62 per cent increase in yield. The seed treatment with bioagents viz; Trichoderma koningii (DMA-8), Trichoderma koningii (JMA-11), Trichoderma harzianum (SMA-5), Trichoderma harzianum (TH-11) and Trichoderma viride was less effective and gave only 4.88 to 10.98 disease control with 2.79 to 6.04 per cent yield increase. all the five fungicides viz; mancozeb 75WP, carbendazim 50WP, propiconazole 25EC, tebuconazole 25EC and trifloxystrobin 25% + tebuconazole 50% were found effective and gave 42.58 to 77.99 per cent disease control with 33.12 to 43.18 per cent yield increase over check.
