Dear Steve,

For rust you may want to apply tebuconazole (250 mg/ml active ingredient) 1 ml/l of water 10-14 dasys interval, or even bettrer: tebuconazole (160 mg/ml) + triadimenole (40 mg/ml) + spiroxamin (250 mg/ml) 1 ml/l, biweekly. You have to start spraying as soon as the first leaf starts to unfold, and stop when it turns from yellow do brown. To cure an infection you should do the spraying in at least 2 consecutive years, 3 consecitive yers are the best. When spraying also note that it shopuld be a spray or mist like action on the leaf, if droplets roll down from the leaf it may cause burn (phytotoxicity) at the point where it rolles of from the leaf.

With Best Regards,
