Technology

Centre : National Research Centre for Banana
Name of the technology :
Management of Fusarium wilt disease using bioagents/botanical

Inventors

1. Thangavelu,R
2. M. Gopi

Procedure / Summary :

Combined application of rice chaffy grain formulation of fungal endophytic Penicillium pinophilumBc2 + rhizospheric Trichoderma sp NRCB3@ 50 g/ plant soil drenching with liquid formulation containing endophytic Trichoderma asperellum Prr2 + Bacillus flexus Tvpr1 @ one litre/ plant or soil drenching with aqueous Zimmu leaf extract (50%conc) @ one litre/ plant for three times (at the time of planting, 2nd month after planting and 4th month after planting) recorded almost complete control of the disease and increase in the yield (170.5%) under field condition(internal disease score of 1.1 as against 6.0 in the control). These treatments also increased the plant growth and yield characters particularly bunch weight (170.5%) significantly and 100% harvest of good bunches compared to only 35% harvest in the control plants

Applications

Useful to manage the Fusarium wilt disease of banana under field condition

Advantages

The technology developed is more effective in suppressing the disease under field condition and cost effective

Status of Commercialization : Not applicable
