Management of early blight of tomato (<em>Alternaria solani</em>) through new generation fungicides under field condition

Abstract

Early blight of tomato is serious threat to tomato cultivation and causes major yield loss. Fungicides application is only the practical way of management of diseases under severe disease incidence condition. In present study, new fungicidal molecules were evaluated against early blight of tomato under field condition. Among different fungicides, Azoxystrobin 11% + Tebuconazole 18.3% SC with 1000 ml/ha dosage (17.14% PDI) showed the least incidence of the early blight compared to other tested fungicides and untreated control (63.63%) after 3rdfoliar sprays. Maximum fruit yield (418.30 Q/ha) was recorded in treatment Azoxystrobin 11% + Tebuconazole 18.3% SC @ 1000 ml/ha and significantly superior over rest of the treatments.
