Erect Head Control in April Sown Wheat locations
Aims

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

Individual objectives specific to the trial were:
- To determine the value of BYDV tolerance in HRZ wheat crops using tolerant and non-tolerant cultivars.
- 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

• There were significant yield increases in both BYDV non-tolerant (Anapurna) and assumed tolerant germplasm (DS Bennett) due to insecticide management.
• The application of insecticide for BYDV control produced a significant reduction in the level of BYDV (4% plot affected – mean of two varieties).
• There was no significant difference amongst the insecticide strategies in terms of BYDV control with an application of neonicotinoid seed treatment (Gaucho) generating the same level of control and yield response as multiple insecticide applications.
