Harvest-Aid Applications In Soybeans

UGA Extension Weed Scientist Dr. Eric Prostko warns us to avoid early-harvest-aid applications in soybeans.

“Early applications (>40% seed moisture) will likely result in significant soybean yield loss as a result of reduced seed weights (Below).  The 40% seed moisture contest roughly coincides with the R6.5 to R7 stages of growth.  R6.5 = Full Seed = all normal pods on 4 uppermost nodes have pod cavities filled.  R7 = Beginning Maturity = one normal pod on main stem of all plants has reached mature color (Below). Official UGA soybean harvest aid recommendations can be found on page 517 of the 2014 UGA Pest Management Handbook. ”
