Weed control in chickpea with safiufenacil and pendimethalin combinations

摘要

Broadleaf weed control was evaluated in 'Sierra' chickpea at the University of Idaho research farm near Genesee, Idaho. Chickpea was seeded into barley stubble with a Flexicoil 8000 direct seed drill with Barton II disk type openers on May 14, 2010. On the same day, herbicides were applied pre-emergence with a CO_2 pressurized, backpack sprayer calibrated to deliver 15 gpa at 30 psi and 3 mph. Air and soil temperatures, soil pH, organic matter, CEC, and texture were 80 F, 65 F, 5.6, 2.9%, 28 cmol(+)/kg, and silt loam, respectively. The soil surface was dry with good moisture at 1.5 inch. The experiment was a randomized complete block design with four replications and plots were 8 by 25 ft. Chickpea injury and weed control were evaluated visually.
