Abstract:
Chickpea (Cicer arietinum L.) is one of the major rabi pulse crop and is a cheap source of
protein. It has also advantages in the management of soil fertility particularly in dry lands
and the semiarid tropics. Despite of low productivity of chickpea is attributed to Fusarium
wilt disease which caused by obligate biotroph Fusarium oxysporum f.sp. ciceri is
consider one of the major limiting factor. Experiment was conducted for find out the in vitro efficacy of bioagents and phytoextracts against Fusarium oxysporum f.sp. ciceri. Out
of different bioagents tested, T. harzianum gave maximum inhibition (79.63 %) of mycelia
growth of test fungus followed by T. koningii with 77.78 % inhibition and least effective is
G. virens with 55.93 % inhibited fungus growth. In different phyoextracts tested, A. indica
showed highest inhibition (16.30 %, 34.56 % and 52.59 %) of test fungus in spite of 2 %,
5% and 10 % respectively compare to others. This was followed by L. camera with
12.59%, 29.83% and 44.23 % and lowest inhibition found J. gossypifolia with 4.44 %,
19.26 % and 35.64 % in terms of 2 %, 5% and 10 % respectively. The above findings are
very useful for the farmers for making decision over the use of bio based fungicides for
management of wilt disease which is safe management practice for environment.
