Abstract
Cowpea (Vigna unguiculata L.) is one of the important pulse crop grown in
India. Root-Knot Nematode, Meloidogyne incognita is widely distributed in India and
cause severe damage to cowpea. Various nematicides which have so far been used to
control root-knot nematode are not only expensive and cumbursome to apply, but also
hazardous to human beings and the environment. In view to reduce dependence on
nematicides, alternative methods which are eco-friendly and feasible to the growers
have been tried.
Efficacy of different bioagents viz., Trichoderma viride, T. harzianum and
Pseudomonas fluorescens was evaluated against root-knot nematode, M. incognita.
Results showed that soil application with T. harzianum @ 3 g/kg soil was
found best treatment to improved plant growth characters and to reduced nematode
reproduction on cowpea.
Results also showed that T. harzianum 10 g/kg seed treatment was found best
to improve plant growth characters and to reduce nematode reproduction on cowpea.
In another experiment combined effect of bioagents as soil application & seed
treatment showed that the T. harzianum @ 1.5 g/kg soil + T. harzianum @ 5 g/kg
seed was the best treatment to improve plant growth characters of cowpea and to
reduce nematode reproduction significantly.
