ROCKILLE, Md. (DTN) — Between a Mother’s Day freeze and recent flooding, many soybean acres in the Midwest may need to be replanted in the weeks to come.
Growers with dicamba-tolerant Xtend soybeans should keep in mind the tight windows for legal applications, cautioned University of Illinois weed scientist Aaron Hager. Many growers face application limits from both the federal label and from state cutoff dates.
“If you completely replant a dicamba soybean field right now, you may get a new 45-day window to spray dicamba from the federal label; but in Illinois, you also have to remember that June 20 is the state-mandated last day of dicamba applications in soybeans,” Hager said.
The Illinois Department of Agriculture also instituted a temperature cutoff for dicamba applications of 85 degrees, which is still in place. See more here: https://www2.illinois.gov/….
Indiana farmers also face a June 20 cutoff. The Office of Indiana State Chemist hopes the new limit this year will cut the state’s dicamba injury complaints — which surged to a record 178 last year — in half in 2020, said David Scott, pesticide program administrator for the agency.
