Abstract:
Pigeon pea (<em>Cajanus Cajan</em> L. Millsp.) is an important pulse crop of India and grown in <em>Kharif</em> seasons. <em>Alternaria</em> blight caused by <em>Alternaria tenuissima</em> is one of the most important disease of pre-rabi Pigeon pea. An inexpensive and environment friendly management regimen is required to minimize loss due to <em>A. tenuissima. </em>The inhibitory effect of 17 botanicals were evaluated both <em>in vitro</em> and <em>in vivo</em> at 10 and 15 per cent concentration of plant extracts against <em>A. tenuissima</em>. The results showed that the effectiveness of extracts was directly proportional to their concentration. Among all plant extracts were neem showed maximum inhibition against <em>A. tenuissima </em>at 15% concentration after 7 days of incubation <em>in vitro</em> followed by Eucalyptus and Garlic. However, percent disease control in between Neem and Eucalyptus; Garlic and Mehandi; Ginger and Tulsi; Kaner and Onion; Lantana and Sadabahar; Bael and Bhang; Parthenium and Marigold were at par to each other.
