The effectiveness of thermal treatment of sunflower seeds in warm water at 40 deg C in protecting sunflower seed against Botrytis cinerea (hybrid NSH-Soleado) ranged from 0.00 to 3.00, while the degree of infection of untreated seeds was 54.00. The average germination of sunflower seeds at all exposures, from 15 to 25 minutes at water temperature of 40 deg C, increased from 54.00 to 72.54. So far none of the fungicides showed similar effects in protecting sunflower seeds from the Gray Rot pathogen Botrytis cinerea. It is also important to emphasize that by combining thermal treatment with fungicide treatment, Botrytis cinerea can be fully controlled during the time of plant emergence and germination.
