AN experimental directed sprayer was developed to apply herbicides postemergence between crop rows under no-tillage conditions. The sprayer consisted of multiple units on a rear-mounted tractor toolbar. The units operated on residue-covered field surfaces without bouncing or collecting residues. Emerged weeds were effectively controlled in 40-cm tall grain sorghum with paraquat (1,1' -dimethyl- 4,4' -bipyridininium ion) and ametryn [KL-etyKM' -(1-methylethyl) - 6 - (methylthio) -1, 3, 5-triazine-2, 4-diamine] and negligible crop injury resulted.
