In vitro studies on dry root rot in chickpea by using fungicides, natural farming products and organic amendments

Abstract

Dry root rot caused by Rhizoctonia bataticola (Taub.) Butler is emerging as a serious biotic constraint for chickpea production. It is the most important and widespread soil borne disease of chickpea. Among the several constraints affecting the productivity of chickpea, 10-35 percent loss in yields are due to dry root rot diseases. Among them, dry root rot caused by Rhizoctonia bataticola is becoming severe in most of the chickpea growing regions of Andhra Pradesh. So to find out the best management strategies for the disease through bio-control agents, fungicides, natural farming products and organic amendments, investigation was carried during rabi 2017-18 in the study area.
