Chemical overlap when spraying is costly in product and sometimes in added crop stress that can cut yield. But it’s next to impossible to prevent it on headlands and on point rows. Plus, sprayer skips can be costly when unsprayed weeds rob yields.

John Deere’s automated solution to these costly problems is Swath Control Pro, designed to control boom sections in its 4720 and 4920 self-propelled sprayers, as well as its brand new 30 series sprayers. Swath Control Pro is part of Deere’s GreenStar 2 (GS2) system, using GPS to turn boom sections on and off automatically, according to a coverage map.

For pull-type sprayers, John Deere offers the GreenStar 2 Rate Controller. It allows growers to reduce cab clutter and replace current rate controllers by using the Deere GS2 system.
