Use of non-conventional chemicals against stem rot of groundnut (Arachis hypogaea L.) caused by sclerotium rolfsii sacc.

Stem rot of groundnut (Arachis hypogaea L.) caused by Sclerotium rolfsii Sacc. is a serious fungal disease of groundnut. Conventional uses of fungicides are toxic to environment thus an eco-friendly new approach of management with nonconventional chemicals as seed treatment was undertaken. Seeds of groundnut were soaked in non-conventional chemicals namely, ZnSO4, ZnCl2, BaSO4, BaCl2, Cycocel and Indole Acetic Acid (I.A.A) @ 10-4 and 10 -5 Molar concentrations for 24 hours to evaluate its bio-efficacy against the disease. The results of the present study revealed that lowest disease incidence (25.7 %) , lowest disease severity (21.7%) as well as highest significant yield (486.8 g / m2 ) was recorded when seeds are soaked in solution of IAA at 10-5 M concentration for 24 hours. | Use of non-conventional chemicals against stem rot of groundnut Arachis hypogaea L. caused by sclerotium rolfsii sacc.
