Key Points
- The major disease impacting a linseed crop in mid Canterbury in the 2003/04 season was pasmo (Mycosphaerella linicola).
- Two timings of fungicide treatments were tested, at early flowering or at both early and late flowering.
- Birds significantly reduced the trial yields so this data is not useful.
- Disease levels, however, showed that pasmo control was not affected by fungicide application at early flowering but was much improved (although not significant) by a late flowering application of iprodione (Rovral Flo).
- As the pasmo had not yet appeared by the time of the second fungicide application, a post-flowering fungicide may have further improved disease control.
