Protect, Scout and Spray to Keep Stripe Rust Away
Stripe rust has hurt cereal production worldwide and in recent years, it’s been known to wreak havoc on wheat fields in the Great Plains. Stripe rust hits early in the growing season and favors wet, cool, humid conditions, stunts crop growth and has the potential to cause up to 40 percent yield loss. Epidemics of stripe rust are common and will continue to haunt wheat crops in wet years. The good news is that it can be controlled with proactive management.
Protect with the Seed
Begin protecting your yield by choosing seed with disease-resistant varieties. Kansas State University reports that disease-resistant varieties are the best means of stripe rust prevention. It’s also important to apply a seed treatment to protect against early-season disease. Gaucho® XT provides early season protection from important seed-borne and soil-borne diseases that reduce germination, forage production and yield potential. Gaucho XT also provides early season suppression of powdery mildew and wheat leaf rust.
Once the wheat begins to emerge, it’s time to watch for disease. Keep up with monitoring reports for disease in your area. Yield loss can be prevented with a timely fungicide application but this requires early scouting, before flag leaf emergence. Plan to scout early and often.
Stripe rust is also known as “yellow rust” due to the appearance of long stripes of small yellow lesions that appear on the wheat. Most often the disease appears on the leaves but other areas - glumes, the spikes and the base of the awns - can also become affected. Kansas State University warns symptoms of stripe rust can vary based on variety. Varieties with resistance to the disease can have tan colored lesions.
Lesions produce spores in massive amounts and those can be carried by the wind and spread the disease at later stages.
Time to Spray
Foliar fungicides can control stripe rust but they should be applied either before infection, or at the first sign of infection. Stripe Rust can spread rapidly and needs to be addressed early to avoid irreparable damage to the crop. Absolute® Maxx is a cost-effective option for fast control of stripe rust, maximizing yield potential of your winter wheat. Trial results in Stillwater, Oklahoma, 2016 show that winter wheat with a stripe rust severity at 90 percent treated with Absolute Maxx yielded 72 bu/A. Absolute Maxx got the highest yield to rate to severity ratio when compared to competitors: Tilt®, Folicur®, Twinline®, Nexicor® and Trivapro®.
