Abstract
Blight of linseed caused by Alternaria lini is most important disease in linseed grown areas of Vidarbha. From 22 different isolates of A. lini collected from the AICRP (Linseed) Nagpur, 10 were found pathogenic and 12 were non pathogenic. The effects of these 12 non pathogenic isolates were evaluated by poisoned food technique against the 10 pathogenic isolates on the basis of radial mycelial growth, sporulation inhibition and spore germination by hanging drop method. From the study it was observed that the non pathogenic isolate ANP-4 had shown maximum fungistatic potential with an average of 77.74 per cent mycelial growth inhibition. However, antisporulant properties of all the treatments showed significant results over control but among that the treatment ANP- 6 had given maximum reduction in sporulation (77.64 per cent ) whereas maximum spore reduction (79.74 per cent ) was observed in ANP-4 treatment.
