Aims

To provide growers with information which will reduce losses due to eyespot by improving our understanding of:
• Resistance responses of commercial cultivars and breeders’ lines to eyespot.
• Yield losses due to eyespot in cultivars with different resistance rankings for eyespot.
• The effectiveness of delayed fungicide application for eyespot management in the South East.
• Interactions between MS and S varieties and fungicide efficacy.
• Impact of fungicides, varieties and combinations on eyespot inoculum carryover.

Key messages

• Know the risk of yield loss from eyespot before sowing a cereal - inspect stem bases (lodging does not always occur) in a previous cereal crop or take soil samples pre-sowing and submit them to PreDicta B for analysis.
• Select less susceptible varieties which are well adapted to the area - untreated they will perform better and they may also be more responsive to fungicide application, particularly where disease pressure is high. Avoid varieties with weak straw strength as they are more likely to lodge when affected by eyespot.
• No fungicides are registered at present for eyespot management, but a number are in the process of registration. Once these are registered - use the correct rate (lower rates can be less effective); apply before canopy closure (GS30-31 is usually recommended); use high water rates; target the base of the plant.
• Delays (due to waterlogging) in fungicide application until after early stem elongation may reduce eyespot incidence and severity but may not give a yield response.
• Inoculum carryover is unlikely to be influenced by variety resistance alone but is likely to be reduced where a fungicide is applied prior to canopy closure. Greatest reductions in inoculum carryover were seen where two fungicide applications were made (tillering plus GS30-31) or where one fungicide application was made to a less susceptible variety.
