Prosaro Product Overview
What is Prosaro fungicide?
Prosaro® fungicide offers broad-spectrum disease control in wheat and barley, including Fusarium head blight (scab) and other leaf and head diseases. Prosaro combines two active ingredients, each with a proven track record of performance to help you maximize yield, improve grain quality and increase profit potential. Learn more about how Prosaro can protect your cereal crops from disease.
How does Prosaro work?
Prosaro inhibits the ability of fungi to produce important components of cell membranes, leading to cell disruption and eventual death of the pathogen. Prosaro stops the penetration of the pathogen into the plant and stops the spread of infection within the plant. As a result, Prosaro inhibits the reproduction and further growth of the targeted fungi.
Why should I believe Prosaro works?
Prosaro has been rigorously tested in the United States and abroad. It is the most-used product in the United States for scab protection, and it is the standard scab fungicide in European countries where it is registered for use.
Prosaro Product Specs
What diseases can I manage with Prosaro?
Prosaro fungicide controls most major leaf and head diseases in wheat, including scab, leaf, stem and stripe rusts, septoria leaf spot, glume blotch, tan spot and powdery mildew. In barley, Prosaro provides suppression of scab and controls net blotch, powdery mildew, rusts and spot blotch. Learn more about Prosaro and the key cereal diseases it controls.
How is Prosaro different from strobilurin chemistry?
Prosaro, a fungicide with two active ingredients, can control all the same diseases as strobilurin chemistries, with the added benefit of helping to manage levels of deoxynivalenol (DON), or vomitoxin. Strobilurins applied after flag leaf emergence may actually allow levels of DON to increase.
DON is a mycotoxin that can be produced in wheat and barley grain infected by scab. This means they may not be acceptable for purchase. Prosaro fungicide can help protect wheat and barley grain from the damaging effects of scab and DON.
Prosaro Application and Use
When should I apply Prosaro?
The best conditions for growth and yield potential are also ripe for disease development: warm, humid weather. Apply Prosaro to wheat at 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 once it has had the chance to fully dry on the leaf surface. For complete application details, review the Prosaro fungicide label.
What should I do when I see early disease pressure in my cereal crops?
There are situations in which the pressure of various diseases, such as powdery mildew and stripe rust, becomes apparent before your crop reaches flag leaf stage. Fusarium head blight, or scab, is not yet a threat to grain quality in these early stages. Make an early season application of Stratego® YLD fungicide or Delaro® fungicide followed by an application of Prosaro at early flowering or later, depending on which diseases are targeted.
What is the shelf life of Prosaro?
Prosaro is a very stable formulation that can be stored for several years – and even longer under ideal storage conditions.
What are the best storage practices for Prosaro?
It’s ideal to store Prosaro at room temperature. Since that isn’t always possible, protect it from intense heat and prolonged freezing. If the product does freeze, shake it after thawing so it can be re-suspended properly.
