Tineweeding Trials


In 2010, the University of Vermont Extension Crops and Soils Team conducted an evaluation of tineweeding as a weed management strategy in corn and sunflowers in Alburgh, VT. Tineweeding is a type of mechanical cultivation that is implemented early on in the field season (Figure 1). A tineweeder is a low cost and simple piece of equipment designed to disturb the root zones of weed seedlings while they are in the very delicate “white thread root” stage (Figure 2). This disturbance often results in weed seedling desiccation and death. Success of this practice is highly dependent on weather conditions at the time of weeding. Wet soils can prohibit the use of tineweeders when weeds are at the critical white thread stage
