Erect Head Control in April Sown Wheat locations
Aims

To assess the principal causes of erect heads in April sown wheat crops

Individual objectives specific to the trial were:
- To determine the value of Barley Yellow Dwarf Virus (BYDV) tolerance in HRZ wheat crops using a tolerant (cv Manning) and a non-tolerant (cv Revenue) cultivar.
- To assess the connection between erect heads and stem base disease complex e.g. crown rot, eyespot, sharp eyespot in the presence of different stem base fungicide applications.

Key messages

 No BYDV was observed in the trial and as a result there were no significant yield differences due to BYDV control recorded in either Manning (tolerant) or Revenue (non BYDV tolerant) cultivars.
 Omitting the GS31 fungicide however (treatment 7 & 8) had a significant impact on grain yield with both Manning (minus 2.13t/ha) and Revenue (minus 2.34t/ha).
 Adding azoxystrobin to the first fungicide application at GS31 over and above the experimental fungicide increased yield with Manning but not with Revenue.
 The additional application of Dominex Duo along with the experimental fungicide (as opposed to Opus 250mL/ha) at GS31 significantly increased the yield of the non BYDV tolerant cultivar Revenue but the yield of Manning was unaffected.
 The “Revenue BYDV tolerant bred line” with no insecticide input was the highest yielding treatment of Revenue and not significantly different from the best Manning treatment that received azoxystrobin at GS31.
