Description A study was conducted during 2003 and 2004 at Nauni to find out the efficacy of soil solarization, different fungicides, residues of crucifer crops and species of Trichodenna against wilt pathogen (Fusariulil oXJ'sponal1 Schl f sp gladioli (Massey) Syn & Hans) of gladiolus (Gladiolus grand(t7orlls L) so that the effective treatments could be integrated for effective management ofthe wilt disease ofgladiolus. Seven fungicides were tested against the wilt pathogen and Quintal (carbcndazim + iprodione) was found most effective in vitro with 89.3/o inhibition in radial growth of mycelium. Residues of 6 crucifer crops were tested under solarized conditions against the wilt pathogen and cabbage (Brassica oleracea var capitala L) was found most effective with 75 to 87.6 % inhibition in mycelial growth in conlparison to non-solarized control. Out of5 species of Trichoderma evaluated for their antagonistic activity against the wilt pathogen, T. vide was found almost effective with 62.40/0 inhibition in nlycelial growth. Along different cominations of effective treatnlents with soil solarization, cornl dip in Quintal (0.25%) + soil amcndnlcnt ofcabbage leaves (10 tonncs/ha) in solarized soil was found most effective with 2.8 to 5.5'O incidence of wilt of gladiolus in comparison to 49.9 to 58.3 010 in non-treated and nonsolarized control plots. This treatInent also resulted in40.1 to 43.3,34.3 - 37.7,25.9- 30.9,54.3 - 168.7 and 200.0 -218.4 0/0 increase in shoot length, spike length, average size of corn1S, average weight of corms and number of cormels/cron respectively and also caused 24.1 - 27.5 % reduction in nunlbcr of days to flowering in cOInparison to the untreated and non-solarized control.
