Scottville, 49454 Northwest Michigan
Here is an excellent article that discusses when to spray for fursarium head scab. Sure does a better job of explaining it than I could.
Please note the following comment from that article. It goes to show how critical timing is for head scab control.
" In a normal year, that translates into about a 36-hour window for optimum timing; treating prior to or after that ideal window usually results in about a 10 to 20 percent loss in control for each day the window is missed."
