2 HGCA Information Sheet 19/Spring 2013 Fungicide dose-response curves Fungicides are rigorously tested in HGCA-funded trials. Each year, a single spray is applied at a range of doses on varieties that are very susceptible to each major disease and at sites where disease pressure is high. Disease levels are observed a few weeks later. Performance of individual active ingredients can be assessed by comparing dose-response curves. These show average performance measured across a range of sites, seasons and leaf layers.

'Eradication' curves indicate fungicidal activity after infection has occurred but before symptoms become visible. Performance of products on each leaf layer and at each site was classified as protectant or eradicant based on timing of leaf emergence relative to spray application. Seguris *Phoenix and Imtrex curves are based on one year's data only. Use Imtrex only in mixture with at least one fungicide with an alternative mode of action that has efficacy against the target pathogen.

4 Fungicide activity and performance in wheat Choosing fungicides Fungicides should be matched to the primary disease risk, which depends mainly on variety, sowing date, location and local weather. Often fungicide mixtures with different properties, from different fungicide groups, are most effective. Fungicide resistance can dramatically affect fungicide performance, so new information should be taken into account when planning fungicide programmes.
