Leaf diseases in cereal crops continue to rob Western Canadian farmers of yield and profit. Scald, Net Blotch, and Spot Blotch have been known to reduce barley yields up to 20%1 and Crown Rust can cause oat yield losses of 10% to 40% in the rust prone areas of Manitoba and Eastern Saskatchewan.2
While cereal farmers can manage foliar diseases effectively by reacting quickly to an outbreak in their field, the best way to protect their barley, oat and wheat crops is through making proactive disease management decisions.

For windborne diseases like Net Blotch and Spot Blotch, warm humid weather, field location, topography and prevailing wind direction are important factors to consider. Scald tends to be an issue in cooler, wetter regions3 while late planting of oats followed by increased temperatures create favourable conditions for Crown Rust development.
As these leaf diseases have the ability to significantly impact yield potential in cereal crops, it is important that growers take a proactive approach to disease management. Here are six recommended proactive strategies to follow:
Cerefit is a dual mode of action fungicide that provides both preventative and curative activity for enhanced control and excellent resistance management. Cerefit provides a unique combination of a Group 11 and Group 3 fungicide, using multiple modes of action to help manage resistance.
