Stand Up to Stalk Lodging with a Strobilurin Fungicide

With corn planted later this season into cooler and wetter soils, are you concerned about disease or reduced stalk strength?   
Strobilurin fungicides were designed to provide corn with superior protection and curative abilities against a wide array of yield-robbing diseases. Additionally, other benefits from strobilurin fungicides have been recognized, including improved stalk standability. 
The potential yield loss from decreased standability can put a strain on both your combine as well as your wallet. As Bob Nielson, Purdue University Extension agronomist, stated in an article on the topic, “Annual yield losses due to stalk lodging in the U.S. range between 5 and 25 percent. In addition to outright yield losses, grain quality may also decline as a result of stalk lodging.1
Stronger stalks and longer stand lead to an easier harvest and less potential for stalk breakage or ear fall that results in volunteer corn the following season. Strobilurin fungicides work hard to improve the performance of your corn through broad-spectrum disease control, greater green leaf area and better photosynthesis, as well as increased water use efficiency. All of this impacts the health and strength of the stalk, and will allow you to look forward to stronger stalks, longer stand for greater harvestability and less volunteer corn next season.
