Of the thirty-two seed diffusates tested, ten were found to be effective against the seed-borne fungi of sunflower namely Alternaria alternata, Emericellopsis terricola, Fussarium solani, Macrophomina phaseolina and Stemphyllum helianthi. Out of these ten, six seed diffusates, those of Anethum graveolens, Azadirachta indica, Canabis sativa, Coriandrum sativum, Melia azedarach and Memordica charantia, inhibited the growth higher in all fungi under test in the concentrations of 0.5 and 1.0 percent. Results of the present study indicate that seed diffusates could substitute costly chemical in controlling the seed-borne diseases.
