Influence of AC 263, 222 Rate and Application Method on Weed Management in Peanut (Arachis hypogaea)

摘要

Experiments were conducted in 1991 and 1992 to evaluate the weed control effectiveness from several rates of AC 263, 222 applied PPI and PRE (36 and 72 g ai/ha), early POST (EPOST) (18, 36, 54, or 72 g/ha), POST (18, 36, 54, or 72 g/ha), and EPOST followed by (fb) POST (27 fb 27 g/ha or 36 fb 36 g/ha). These treatments were compared to the commercial standard of bentazon at 0.28 kg ai/ha plus paraquat at 0.14 kg ai/ha EPOST fb bentazon at 0.56 kg/ha plus paraquat at 0.14 kg/ha plus 2, 4-DB at 0.28 kg ae/ha. Application method had little effect on weed control with AC 263, 222.
