Lentil (Lens culinaris M) has expanded importance in India as well as various parts of Rajasthan as potential pulses crop. This crop suffers from many diseases among which vascular wilt of lentil caused by Fusarium oxysporum f. sp. lentis, has become a thoughtful trouble in recent years in Rajasthan and in other lentil growing parts of India, resulting heavy yield losses. Systematic studies in laboratory were conducted during 2017-18 to inhibit growth of Fusarium oxysporum f. sp. lentis.

... ory experiments were carried out in Completely Randomized design with four replications using poisoned food technique during 2017-18. The efficacy of eight various systemic and non-systemic fungicides was evaluated in vitro at four concentrations viz., 50, 100, 150 and 200 ppm concentration. Companion (Carbendazim 12% + Mancozeb 63 % WP) gave maximum cent percent inhibition of mycelial growth at 200 ppm concentration followed by Carbendazim at 200 ppm concentration. Chlorothalonil was found least effective at all concentrations against Fusarium oxysporum f. sp. lentis. Rest of fungicides viz., Propiconazole, Difenconazole and Tabuconazole were also found highly significant at all concentrations over control.
