摘要

A study was conducted at the University of Idaho Research and Extension Center near Kimberly, Idaho to compare pendimethalin to several postemergence herbicides for weed control in spring wheat. 'Klassic' was planted April 22, 2006 at 115 lb/A. Experimental design was a randomized complete block with four replications and individual plots were 8 by 30 ft. Soil type was a Portneuf silt loam (5.3% sand, 75.7% silt, and 18.9% clay) with a pH of 8.1, 1.95% organic matter, and CEC of 16.4-meq/100 g soil.Herbicides were broadcast-applied with a CO_2-pressurized bicycle-wheel sprayer calibrated to deliver 10 gpa using 11001 flat fan nozzles. Additional environmental and application information is given in Table 1. Kochia (KCHSC), common lambsquarters (CHEAL), and redroot pigweed (AMARE) were the major weed species present. Crop injury and weed control were evaluated visually 18 and 34 days after last treatment (DALT), on June 12 and 28, respectively. Grain was harvested August 8 with a small-plot combine.
