Abstract:
Pigeon pea is an important pulse crop of India and its production is greatly affected by wilt disease. Pigeon pea wilt is a very destructive soil borne disease caused by <em>Fusariumudam</em>. In present research work plant extracts (Garlic, Neem, Tulsi), bio-agents (<em>Trichodrema viride</em> and <em>Pseudomonas fluorescens</em>) and fungicides (Vitavax, Bavistin and Thiram + Carbendazim) were tested against <em>Fusarium udum</em>. Fungicides namely Vitavax Power (0.2%), Bavistin 25SD (0.1%), Thiram + Carbendazim (0.3%)<em> </em>were tested by poisoned food technique <em>in vitro</em> and resulted cent per cent restriction of radial growth of <em>F. udum </em>up to 96 hrs. The results indicate that the antagonist effect on radial growth of <em>F. udum </em>was highest in<em> Pseudomonas fluorescens</em> (4.82 to 5.95mm) followed by<em> T. viride </em>(5.15 to 6.66mm) in comparison to check (81.00 to 90.00mm). The maximum inhibition was recorded at 10% concentration. The radial growth in plant extracts ranged from 2.32mm (Garlic bulb) to 6.15mm (Neem leaves) at 48 hrs of incubation period. The similar trends were also observed in 5% concentration of all incubation period.
