The Soybean Watch ’21 area is comparatively weed-free, apart from some points with volunteer corn. Nevertheless, Steve Gauck has flown over different fields in Indiana along with his drone in August and picked up weed issues not so seen from the street.
Gauck, a regional agronomy supervisor for Beck’s, sponsor of Soybean Watch ’21, earned his Federal Aviation Administration pilot’s certificates early on. He maintains it so he can fly fields for patrons who need to monitor patterns that aren’t simply picked up by driving by. Among the patterns aren’t obvious from floor stage, even in case you stroll a area — even a soybean area.

One of many fields Gauck flew over lately confirmed a definite sample of weeds breaking by means of protection in early August. “The streaks stand out because weeds tend to be a lighter color than soybean plants, especially if nitrogen nodules have worked well and soybeans are in good condition,” he says. “If we go lower, we can often get a pretty good handle on what weed is causing problems in a particular field.”
Canada thistle patches have a particular sample from the air and are simple to positively establish in case you fly decrease over the crop, he provides. Large ragweed patches are additionally comparatively simple to spot and establish from aerial pictures.
Within the area proven within the aerial picture above, Gauck suspected the weed outbreaks coming by means of have been waterhemp crops, though he couldn’t inform for positive with out ground-truthing the sphere. Since somebody had checked the sphere after it was sprayed postemergence earlier within the season and famous waterhemp attempting to regrow after the appliance, that additional led him to consider waterhemp was most likely displaying up within the aerial picture.

Waterhemp is hard, and in case you don’t management it utterly the primary time, it should regrow, even when the herbicide utility knocked it again, Gauck says. It’s additionally one that may germinate and break by means of later within the season, even when escapes from an early cross didn’t regrow.
“It’s a tough weed to control. Plus, if it goes to seed, it can produce tons of seeds per plant,” he says. “Even if the plant regrew after surviving an early spray application, it can still produce a large quantity of seed before harvest, in some cases.”
Monitoring weeds, leaping on them early and stopping competitors with soybeans is essential in giving beans an opportunity to attain their yield potential, Gauck concludes.
