Early blight has become a more significant disease in some varieties in recent years. New research in Europe warns that it’s also a disease that is evolving into something that’s more aggressive and harder to control. CPM finds out more. Crop health is a factor in early blight disease onset. By Rob Jones and Lucy de la Pasture Across Europe, growers are being encouraged to give greater thought to how they protect crops against early blight (Alternaria spp.), also known as target spot, following the detection of isolates showing reduced sensitivity to fungicides belonging to the Quinone outside Inhibitor (QoI) group of fungicides. Speaking at the Bayer potato conference from his office in the Netherlands, Bert Evenhuis of Wageningen University and Research, reported that a novel genotype of Alternaria solani has been shown to be more aggressive than wild relatives and less well controlled by products containing pyraclostrobin, azoxystrobin and famoxadone. The rising threat of early blight has increased steadily since the turn of the century as a changing climate has created conditions more favourable for the disease, he explains. Efforts to protect crops have led to the increased use of fungicides and, in some cases, this has resulted…
