摘要

The objective of this paper was to evaluate the effect of preplant applications of trifluralin on barley stand and yield, and control of grass weeds in field experiments during 1992 and 1993. Factors examined were: (1) crop planting patterns (conventional drill with rows 15 cm apart and Deep-seeder drill with rows 25 cm apart), (2) herbicide application times (22 d before sowing and Immediately before sowing), and (3) herbicide application. During 1993, hand-weeded plots also Were established. Trifluralin applied preplant at 528 g ai/ha reduced weed density and biomass.
