Assessment the Efficiency of the Bioagent Bacillus velesensis and the Biohealth Formula with Fungicide Beltanol in Control of Fusarium solani Causing Pepper Root Rot

Abstract

Abstract The aim of this study was isolating and diagnosing the causative agent of root rot of pepper in Karbala province and control it using some biological applications. The results showed that the main pathogenic fungus of root rot and damping-off pepper in Karbala Province was Fusarium solani. This fungus was highly pathogenic by inhibition germination of all pepper seeds on the culture medium and in plastic pots. The treatment of integration between among Bacillus velesensis + Biohealth + Beltanol displayed the highest effectiveness in control of the pathogenic F.solani, as it reduced the disease incidence and severity to 9.00, 6.66%, respectively, compared to the pathogenic fungus alone, which amounted to 100%, 86.6%, respectively.
