In vitro studies were carried out to determine whether certain botanicals and bioagents were effective against Rhizoctonia Solani, the organism that causes root rot disease in Sugar beet (Beta Vulgaris L.) plants. Terminalia Arjuna and Pithecellobium dulce (Manila tamarind) were the botanicals, and Trichoderma viride, Trichoderma harzianum, and T. Koningii were the bioagents used in this study. All plant extracts and antagonistic organisms significantly inhibited the growth of Rhizoctonia Solani. However, T. Viride had the greatest inhibitory effect of the antagonists, followed by T. Harzianum and T. Koningii, which have the least suppressive effect. Pithecellobium dulce and Terminalia Arjuna extracts had the strongest inhibitory effects.
