Early blight fungicide table NEW

Efficacy of fungicides for the control of early blight caused by Alternaria solani and Alternaria alternata. Updated 31 July 2017.

1 : Ratings for Alternaria are based on results from EuroBlight field trials during 2015-2016, and only compounds included in these trials are rated for Alternaria. The scale for Alternaria is a 0-5 scale (see technical report to be uploaded soon). 2 : The ratings are intended as a guide only and will be amended in future if new information becomes available. 3 : The active ingredients were sprayed in a spray strategy with a 7 day interval (a) or a 14 day interval (b). 4 : azoxystrobin was sprayed at label rate which is 0.5 for DK and DE, and 0.25 for NL. 5 : Alternaria solani isolates that are less sensitive to QoI-fungicides have been isolated from potato plants in Europe. Therefore resistance management strategies should be implemented (see FRAC web site for details). Rating will be lower where fungicide insensitive strains are present.

Disclaimer: Whilst every effort has been made to ensure that the information is accurate, no liability can be accepted for any error or omission in the content of the table or for any loss, damage or other accident arising from the use of the fungicides listed herein.  Omission of a fungicide does not necessarily mean that it is not approved for use within one or more EU countries. The ratings are based on the label recommendation for a particular product. Where the disease pressure is low, intervals between spray applications may be extended and, in some countries, fungicide applications are made in response to nationally issued spray warnings and/or Decision Support Systems.  It is essential therefore to follow the instructions given on the approved label of a particular early blight fungicide appropriate to the country of use before handling, storing or using any early blight fungicide or other crop protection product.
