When should Prosaro be applied?
The best conditions for wheat and barley growth and yield potential are also ripe for disease development – that is, warm, humid weather.
Apply Prosaro at the optimal timing for wheat-early flowering (Feekes growth stage 10.51) and before scab symptoms are visible-for the best performance.
Optimal Prosaro application timing for barley is at head emergence. The broad-spectrum activity of Prosaro will protect the flag leaf, while holding back head diseases.
Even when scab is not present, Prosaro does an excellent job protecting against all other major leaf and grain head diseases.
Prosaro® is rainfast within two hours of application or until fully dry on the leaf surface.
