Abstract:
Among the fungal diseases of linseed, wilt caused by Fusarium oxysporum f.sp. lini is a major constraint for low production and productivity. An in vitro experiment was conducted to find out effective culture medium, temperature and pH for growth and sporulation of Fusarium oxysporum f.sp. lini. Study showed that fungus grew best on PDA among eight media tested. The maximum growth of the fungus (87.22 mm) was recorded at 25 ºC after seven days of incubation with maximum sporulation and highest growth rate of 12.46 mm per day. Similarly, maximum growth of the fungus (88.16 mm) was recorded at pH 6 with highest growth rate (12.59 mm per day) and maximum sporulation after seven days of incubation.
