Just in time for Halloween, new jack-o-lantern pumpkin research has been published in the ASHS journal HortTechnology.
The research, led by Stephen Meyers, was conducted at 11 locations in 10 different states in 2021. The authors demonstrate that a currently registered pumpkin herbicide can be applied safety in an alternative way, resulting in extended weed control. A big “thank you” to all participating locations and a special “thanks” to the 2021 crews at Meigs, the Southwest Purdue Ag Center, and the Horticulture Crops Weed Science Lab for their assistance with this research!
