Effect of seed treatment with fungicides, nutrients and bio-agents on wilt of lentil (Lens culinaris Medikus)

Abstract

The 10-15 percent yield losses of lentil crop are mainly due to the Fusarium wilt. In the present study, efficacy of seed treatment with fungicide, bioagents and nutrient were evaluated against lentil wilt. Minimum disease incidence (32.33%) was recorded in Carbendazim @ 0.2 g/kg seed followed by Pseudomonas fluorescens (34.21%), Bacillus subtilis (36.45%), Trichoderma viride (41.40%), Trichoderma harzianum (44%), Trichoderma virens (45.44%) Zn (48.80%) and Mn (50.10) as compared to control (53.60%) at 90 days after sowing in the year 2016-17. Maximum disease control (39.68%) was recorded in Carbendazim followed by P. fluorescens (36.17%), B. subtilis (31.99%), T. viride (22.76 %) and T. harzianum (17.91%), Zn (8.95%) and Mn (6.52%). Similar results were also observed in the year 2017-18. Disease incidence was maximum at 90 days after sowing as compared to 60 and 30 days after sowing in both the years.
