Abstract:
Cultivated Flax is commonly known as “Ulsee” or “Tisee” (Linum usitatissimum. L.). Linseed wilt caused by Fusarium oxysporum f.sp. Lini. Pathogen screened out against this fungus. The experiment was conducted in pots under glass house condition, during 2017-18 by using susceptible cultivar Chambal. All the treatments were found significantly superior over check (untreated control) in controlling the disease severity by checking the wilting of plants. Out of 13 treatments, the minimum wilting of 21.11 per cent were recorded with treatment T₄ [Seed (5g/kg seed) and soil treatment (10g/kg soil) with Trichoderma harzianum] followed by T₂ [(Seed (5g/kg seed) and soil treatment (10g/kg soil) with Trichoderma viride], (21.57 per cent) and T₁₂ [(Seed + soil treatment with carbendazim (0.2 Per cent)] (25.00 per cent), respectively. Wilting of the plant started in control pots just 15 to 20 days after sowing while in treated pots, wilting started after 35 to 40 days after sowing. Seed treatments with either Trichodermaspp. or Pseudomonas spp. or with extracts were less effective as compared to treatments of seed and soil both.
