Integrated management of vascular wilt of lentil (Lens culinaris M) incited by Fusarium oxysporum f. sp. Lentis

Abstract

Lentil (Lens culinaris M) has gained importance in 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. Field experiments were conducted during 2016-17 and 2017-18 cropping season to evaluate the effect of different control options (seed treatment with Carbendazim, Trichoderma harzianum and soil drenching alone with chemicals and in combination with organic manures) on lentil wilt caused by Fusarium oxysporum f. sp. lentis. The results indicated that Maximum mean germination per cent (98.71), maximum per cent mean disease control (85.49), mean mortality percentage (8.27) and maximum pooled yield (918.44 kg/ha) of two years 2016-17 & 2017-18 was recorded in soil application with FYM 6t/ha + 2.5 kg/ha Trichoderma harzianum + seed treatment with Carbendazim @ 2g/kg seeds and Maximum 40.71 per cent mean wilt incidence, minimum per cent mean germination (90.82), minimum per cent mean disease control (34.21) and minimum pooled yield (630.35 kg/ha) of two years was reported in treatment soil drenching of Carbendazim + Mancozeb @0.1%/hac.
