Stevia is an important medicinal plant used as a low calorie sweetener. Sclerotium wilt caused by Sclerotium rolfsii is an important disease and is a major constraint in stevia cultivation. Evaluation of the biocontrol agents indicated that maximum inhibition of mycelial growth of S. rolfsii (78.51%) was noticed in Trichoderma harzianum (Dharwad isolate). Among botanicals tested, Durantha was highly effective at 10 per cent (75.14) followed by Glyrecidia (72.14%).
