N2  - The study "Integrated disease management of Fusarium wilt of 
cowpea (Vigna unguiculata sub sp. sesquipedalis (L.) Verdcourt)" was 
conducted at the Department of Plant Pathology, College of Agriculture, 
Vellayani, Kerala Agricultural University during 2001-2003. Three 
species of Fusarium were found associated with cowpea wilt in 
Thiruvananthapuram district. They were identified as Fpallidoroseum, 
Foxysporum, Fisolani. Of these, Fpallidoroseum was the most virulent 
pathogen. 
Two fungal antagonists viz., Trichoderma viride (A7) and T. virens 
(A1S) isolated from cowpea rhizosphere were highly effective in inhibiting 
F pallidoroseum under in vitro conditions. Two fluorescent 
pseudomonads, P, and P9 showed significant suppression of the pathogen. 
Pot culture experiments using biocontrol agents revealed that T. viride was 
most effective in reducing the disease and in enhancing the plant biomass 
and nodulation. 
Among the fungicides tested, mancozeb (0.3 %) and carbendazim 
(0.1 %) showed significant inhibition of the pathogen under in vitro 
conditions and suppression of wilt disease under in vivo conditions. There 
was also enhancement of plant growth and nodulation of cowpea. 
However, carbendazim caused suppression of Trichoderma. So, mancozeb 
was selected as the fungicidal component for development of integrated 
disease management package. 
Neemcake supported the growth of the antagonistic fungus, T. 
viride and inhibited the mycelial growth of the pathogen, F 
pallidoroseum. The soil application of neemcake significantly decreased 
the disease and increased plant growth. 
 
Combination of seed treatments and soil application of T. viride, 
soil application of neemcake (150 kg/ha) and soil drenching with 
mancozeb (0.3 %) effectively suppressed Fusarium wilt of cowpea. It also 
appreciably increased the biomass and pod yield of the crop.
