Abstract:
Linseed (Linum usitatissimum L.) also known as flax, is a member of the family Linaceae. The essential oils are Angiosperm plants species including herbs, shrubs, and tree; extracted by Clevenger Hydro distillation method. So, the present study was undertaken to evaluate the effects of some eco-friendly essential oils against Fusarium oxysporum f. sp. lini, by which we can improve the agricultural production of linseed. In cross-pathogenicity reaction of different crops and linseed against Fusarium oxysporum f.sp. lini isolates, no crops were showing pre-emergence mortality except control (linseed) (31.11%). Post emergence mortality were observed in Chickpea (58.33%) and linseed (51.11%). Total wilt incidence recorded linseed (82.22%) and Chickpea (58.33%). In effect of six isolates of Fusarium in different crops on growth parameters of linseed seedlings, the linseed crop is showing pre- emergence mortality linseed isolate (8.33%), soybean isolate (3.33%) and Chickpea isolate (5.00%). Post emergence mortality shown linseed isolate (73.33%) and Chickpea isolate (56.67%). Total wilt incidence recorded linseed Fusarium (81.67%) and Chickpea Fusarium (61.67%). No post-emergence mortality was shown in case of others Fusarium isolate. Fusarium was re-isolated from the inoculated plants which confirmed the presence of the disease.
