Weed Control in No-Till Pumpkins
Elizabeth T. Maynard, Purdue University - Main CampusFollow
"No-till production systems for pumpkins are of interest to Midwest producers, but achieving
acceptable weed control without cultivation can be difficult. Research was conducted in
Wanatah, Indiana in 2007 to evaluate postemergence weed control options for pumpkins no-till
planted into a fall-seeded, spring-killed winter wheat cover crop. Weeds in no-till pumpkins were controlled reasonably well with a preemergence herbicide
(Strategy®) followed by a hooded sprayer, row-middle application of a nonselective, nonresidual
herbicide (glyphosate). Weed control, yield, and fruit size with this treatment were comparable to
conventional tillage with a preemergence herbicide (Strategy®) and one cultivation. Hand
weeding could be substituted for the nonselective herbicide with similar results. Other treatments
for weed control in no-till pumpkins did not work as well. Even the best weed control treatment in this trial had large weeds present at season’s end.
Additional weed control measures would be required to prevent weed seed production and shed.
Future trials could include additional herbicides labeled for preemergence or row-middle use,
different cover crop management practices, and treatments designed specifically to minimize
weed seed additions to the soil."
