Abstract/Contents:This study was conducted to evaluate four newer materials for their efectiveness in controlling Mexican sprangletop. Initial treatments were applied preemergently using a small, hand-held plot sprayer. Postemergent applications of primisulfuron (Rifle) were made to sprangletop when in the 2 to 3 tiller stage and prior to flower emergence. Both formulations of metolachlor (7.8E and 8.0E) when applied at a rate of 4 lbs ai/A produced excellent control of Mexican sprangletop. In an unmowed situation, the rates of primisulfuron 75WG applied in this study did not control Mexican sprangletop. In this study, metolachlor was not effective in controlling barnyardgrass or spotted spurge when applied preemergently. At the rates applied, primisulfuron was very effective in controlling spotted spurge, but not barnyardgrass.
