Efficacy of different fungicides and biopesticides for the management of lentil wilt (Fusarium oxysporum f. sp. lentis)

Abstract

In Vitro and In Vivo studies on the efficacy of fungicides and biopesticides. Among the fungicides, in Carbedazim to the most effective as they have inhibited the mycelia growth completely of the test fungus, and Benomyl, Topsin - M, Ridomil,Vitavax were found the next best in inhibiting the mycelial growth of the pathogen up to 92.11% to 83.46% respectively. Sadabahar was least effective plant extracts which causes 42 mm of radial growth and inhibited the growth of the only 19.23%. In Vivo condition the maximum seed germination (95.50% and 95.33%), minimum wilt incidence (5.16% and 3.65%) and highest grain yield (10.50 q/ha and 10.35 q/ha) was found seed treatment with Carbendazim (0.2%). Among the test plant extracts Tulsi was lested effective, which show the minimum seed germination (80.00% and 77.50%), maximum wilt incidence (15.70% and 14.10%), and lowest grain yield (3.92 q/ha and 4.17 q/ha).
