Abstract

Septoria leaf blotch complex (Septoria tritici and Septoria nodorum) and powdery mildew (Blumeria graminis) are common foliar diseases of spring wheat in Estonia. This paper reports results of multi-site field experiments performed on spring wheat varieties Tjalve and Munk during 2003-2004 in Estonia. Fungicides Falcon 460 EC and Opera were used in full and reduced doses of one or split applications. The aim of the current study was to obtain efficient disease control and to identify the impact of fungicide application on yield at the time of fungicide application. The biological efficiency of fungicides was assessed based on disease scorings made until growing stages 75-77. The trial results show that biologically and economically effective control of wheat diseases could be achieved with timely use of lowered fungicide doses. Spraying at growing stages 41-55 will often be enough to achieve good control of serious attacks by Septoria.
