... strategies using one, two or three applications and different rates and timings were compared. The fungicide strategies investigated are listed in Table 6. A prototype of CPO was included assessing the need for control based on weekly field inspections. ...

... all three seasons the attack of tan spot in untreated plots reached 60-70% severity on the flag leaf at GS 75-77 (Table 6). The efficacy from the best strategy varied between years from 55% to 97% control indicating that the timing of fungicide application in relation to the epidemic development has an impact of the overall performance of the fungicides. ...

... ha À1 and reflected the level of control, with the highest yields following two-or three- spray strategies. However, when the margin over fungicide cost was calculated a single treatment with half-rate gave the best return, but only minor differences were found between using one-, two-or three-spray strategies (Table 6). ...
