Abstract
Potato early blight caused by Alternaria solani (Ellis and Martin) Jones and Grout is widespread and highly destructive depending upon the variety grown, weather conditions and inoculum load in the soil. The disease is characterized by a series of concentric rings on the host leaf. This also results in a “target spot” effect. The photosynthetic area of the plants is reduced, resulting in a decrease in the number and size of potato tubers. The efficacy of eco-friendly agents applied through tuber treatment and foliar application on disease intensity was evaluated in two field trials. In Rabi 2020–2021 and Rabi 2021–2022, soaking tubers with Beejamrutha (5 l/10 kg tubers) for 30 min and two foliar sprays of Jeevamrutha @ 5% at the interval of disease onset proved to be most effective and economical for environmentally friendly control of potato early blight under field conditions.
