Foliar fungicide applications at or prior to first node stage (Z31) can be effective at controlling leaf spot diseases in susceptible wheat varieties under high disease pressure... Necrotic leaf area was determined on top 3 to 4 leaves (on 15 tillers /plot) from all plots at Z15, Z25, Z31, Z39, Z55 (i.e. before each foliar fungicide spray) and Z72, or in the case of opportunistic trials assessed at regular intervals after trial establishment... The in-furrow fungicides tested show promise for leaf spot disease control and in the future they may become an alternative to foliar applications, for the control of early season leaf spot infections...
