The objectives of these trials are very similar to those pursued last season, those being to establish guidelines on the use of foliar applied fungicides in barley crops.
Again the majority of individual treatment responses to fungicide are positive but not statistically significant, indicating that there is a
trend but it is small. Barley however, poses a dilemma in that the single spray options early and late do not optimise performance against early Scald and late leaf rust infection, as such it is difficult to avoid spraying twice if both diseases pose a threat. In addition, if the rate of both sprays are cut to a bare minimum the results are inferior in terms of disease control. Triazoles are generally not as effective against Scald and diseases such net blotch, by comparison to the rusts.
