Pest Alert: Reports of cereal rust increase

March 16, 2016

Growers should continue to scout and monitor their fields for signs of cereal rust as reports of this disease continue to come in from Arkansas, Colorado, Louisiana, Missouri, Oklahoma, Texas and Washington. Winds, humidity and rainy weather conditions are conducive to disease flare-ups across these cereal-growing regions during mid to late March. Kansas wheat growers should also be on high alert for cereal rust in fields as winds continue to come out of the south.

Growers should be scouting and walking their fields now and continue to do so frequently throughout the season, looking for rust in wet areas, denser canopies and field borders. Even if you don’t see rust, but your neighbors are reporting it in their fields, it could be beneficial to make preventive fungicide applications since this disease can show up seven to 10 days after spores have blown across and into a field.

If you’re making the first fungicide application of the season, Syngenta agronomists recommend using Trivapro™ fungicide at herbicide timing, followed by an additional application at flag leaf, if necessary. This latest fungicide innovation for wheat from Syngenta works ten times harder than competitive brands. Trivapro creates a disease shield with translaminar movement and binds to the leaf’s waxy layer for extended stay-put protection, giving wheat growers the tool they need to help shut down existing disease and prevent future infections.

Another option would be either Quilt Xcel® or Alto® fungicide at herbicide timing, followed by an application of Trivapro during the flag leaf stage, if necessary. This helps provide protection throughout the growing season with control and greening effect for healthier, higher producing plants.

It’s important to regularly scout fields to track the presence of stripe rust and other diseases. Being proactive will help maximize profit potential and ultimately help grow more wheat.
