LAMAR, Mo. – Two-inch tall waterhemp and sedge grass are starting to show up in area corn fields according to Jill Scheidt, agronomy specialist with University of Missouri Extension.
That means now is the best time to treat waterhemp.
“Herbicide treatments are most effective when applied to weeds two inches or less in height and diameter,” said Scheidt.
According to the MFA Agronomy Guide, Callisto products, Status and Realm Q are rated 90 percent or better control for waterhemp.
“These herbicides have a crop height restriction on the label, always read the label before applying any chemical to your field,” said Scheidt.
Due to dry weather, Scheidt says diseases were not present in wheat at the flag leaf and boot stage in the fields she scouted.
“If the weather becomes humid, watch for diseases, if any appear on the lower part of the plant and begin moving toward the flag leaf or appear on the flag leaf, spray a fungicide,” said Scheidt. “It is important to protect the flag leaf from disease because it is responsible for 75 percent of the grain fill.”
Wheat and corn fields were scouted east of Lamar on May 7 by Jill Scheidt, agronomy specialist with University of Missouri Extension.
