Abstract:

In recent years Macrophomina phaseolina causing stem canker of pigeonpea is more problematic in pigeonpea growing parts of Karnataka. Present investigation was taken on evaluation of non-systemic, systemic fungicides and bio-agents against M. phaseolina under laboratory condition. Five non systemic, four non systemic and three combi products were evaluated. Similarly two isolates of Trichoderma spp. four Pseudomonas fluorescens isolates, one Pseudomonas putida and one Bacillus subtilis were evaluated against M. phaseolina by poison food technique and dual culture method respectively. Among fungicides mancozeb, copper hydroxide, carbendazim, benomyl, thiophanate methyl, carbendazim 25 % + mancozeb 50 %, zineb 68 % + hexaconazole14 % and tricyclazole 18 % + mancozeb 62 %, carbendazim 12 % + mancozeb 63 %, recorded maximum inhibition of (100 %) mycelial growth. Among the bio-agents tested Trichoderma harzianum (Th-R) was found more effective as compared to other bio-control agents and inhibited maximum fungal growth (41.86 %) of M. phaseolina.
