The study is aimed at determining the viability of sclerotia of S. rolfsii under pot culture studies.
Eight combination fungicides were used. The fungicides were applied to soil by soil drenching (0.01%).
Furthermore, 10 Trichoderma isolates (T.asperellum GT1, GT4, GT15, GT23, GT25, GT60,
GT61,GTNT and GTw38(2)), five organic amendments and five ITK inputs (Modified Panchagavya,
beejamrutham, jeevamrutham, cow urine and butter milk) were evaluated on sclerotial viability. Out of
the eight fungicides, Hexaconazole 4% + Zineb 68% WP has inhibited sclerotial viability or germination
to 98.88% (Overall mean). Talc based formulations of Trichoderma isolates were applied to soil @5g/
kg soil. Organic amendments were ground into powder and applied to soil @30g/kg, whereas, ITK
inputs applied as soil drenching. Results indicated that, at 5 cm depth of soil. Hexaconazole+Zineb
has inhibited sclerotial germination to cent percent. At 10 cm and 20 cm also this combi fungicides
has shown highest inhibition of germination or viability of sclerotia. In the case of Trichoderma isolates
(T.asperellum GT1, GT4, GT15, GT23, GT25, GT60, GT61,GTNT and GTw38(2).Trichoderma
asperellum GT4 has shown overall mean inhibition of sclerotial germination or viability to 100% with
efficacy at all the three depths. Neem cake (3%) and gingelly cake have inhibited sclerotia to maximum
extent but neem cake was proved to be effective in percent inhibition of sclerotia (97.78%). Out of the
five ITK inputs, modified Panchgavya (10 dilution) was effective with overall mean inhibition of 96.66%
and showed highest percentage of sclerotial inhibition at 5cm,10cm and 20cm when compared to the
Control (untreated plot). The results showed the efficacy of ITK inputs, organic amendments and
Trichoderma isolates in inhibiting sclerotial viability of S. rolfsii under pot culture in greenhouse
conditions.
