Abstract EN

The studies showed significant inhibitory effects of potassium bicarbonate (KHCO3) either on growth parameters of Sclerotium rolfsii or in sunflower root/collar.

Inhibitory effects were increased by enhancing KHCO3 concentration.

KHCO3 gave significant inhibitory effects against Sclerotium rolfsii caused76.6, 57.69 and 95.78% inhibition for linear growth, sclerotial formation and mycelial dry weight, respectively at 0.6g/l KHCO3.

KHCO3provided synergistic effects with Trichoderma harzianum, Since the antagonistic potentiality of T.

harzianum against S.

rolfsii was increased with increasing KHCO3 concentrations.

KHCO3 caused 80 and 76% inhibition for linear growth and sclerotial formation, respectively.

However, the most effective to prevent growth parameters and infectivity of S.

rolfsii the combinations of potassium bicarbonate and hydrogen peroxide (H2O2) with Trihoderma harzianum 86.25% and 97.6% inhibition for radial growth and sclerotial formation at H2O2 (1.2 g/l) +KHCO3 (0.6 g/l) with T.

harzianum, respectively.

The treatments H2O2 (1.2 g/l) +KHCO3 (0.3g/l) with T.

harzianum and H2O2 (1.2 g/l) +KHCO3 (0.6 g/l) with T.

harzianum achieved 75% and 71% protection against sunflower basal stem rot, respectively.
