Key Points
- The 2000/01 season was fairly dry in Canterbury and the Manawatu and only 2 of the 6 trials had a significant yield response to fungicides.
- Stripe rust was the major disease in wheat and all treatments in the irrigated Darfield trial gave economic responses to fungicide use.
- Stripe rust was also the major disease in Methven, while at Kairanga, leaf rust occurred.
- The Sanson barley trial was the only one to give a significant yield response, with the most economic responses following late Opus, regardless of earlier treatments.
- Ramularia was the major disease later in the season at the other barley sites.
