Abstract

Abstract

Preemergent and post emergent herrbicides applied to research plots must be confined to the target area and crop. Our objective was to develop an apparatus hat could be used to apply herbicides effectively for weed control in randomized field plots of multiplec rops with no injury to nontarget crops in adjacent plots. A canopied sprayer that attaches to a row-crop tractor having a standard Category I or II three-point hitch and a PTO was designed and constructed. This sprayer delivered broadcast- and band-applied herbicides to small plots without causing drift-related injury to nontarget crops planted in adjacent plots. Use of this sprayer eliminated wind-blown drift, and ensured the confinement of herbicides to target plots, alleys, and borders.
