Management of coriander wilt (Fusarium oxysporum) through plant extracts and source of resistance

Author(s): Mukesh Kumar Jat and RR Ahir
Abstract: Wilt of coriander incited by Fusarium oxysporum is one of the important disease and a big constraint in successful cultivation. In our investigation four plant extracts in both in vitro and in vivo were tested against wilt disease of coriander. Azadirachta indica leaf extract was found most effective followed by Allium sativum cloves extract in both conditions and Ocimum tenuiflorum were found least effective among these plant extracts. Azadirachta indica leaf extract recorded in vitro inhibition the mycelial growth (56.33%), and in vivo 18.27 per cent disease incidence with 64.81 per cent disease control and 788.35 kg/ha seed yield by increasing 135.79 per cent seed yield. Thirty coriander genotypes/varieties were screened against Fusarium oxysporum under artificial inoculation conditions in field. On the basis of two years observations, it was recorded that four of the genotypes/varieties were resistant (R) RCr-446, RCr-684, RCr-20, RCr-41 were categorized, nineteen genotypes/varieties viz. RCr-475, RCr-480, RCr-728, UD-796, RD-366, UD-426, UD-483, CO-3, UD-743, UD-744, DH-246, NS-2, UD–728, UD-775, UD-630, UD-707, DH-208, RD-120 and RD-154 as moderately resistant, four genotypes/ varieties viz., NS-1, J.Co-387, Co-2, and UD-529 as susceptible and rest three genotype/varieties viz., RCr-435, RCr-446, DH-205 as highly Susceptible.
