摘要

An experiment was conducted at the Kansas State University Southwest Research-Extension Center near Garden City, KS to examine the efficacy of single and sequential herbicide treatments in fallow. Application, environmental, and weed information are given in Table 1. All herbicides were applied using a compressed-CO2 backpack sprayer delivering 20 gpa at 3.0 mph and 27 psi. Soil was a Ulysses silt loam with 1.4% organic matter, pH of 8.0, and cation exchange capacity of 18.4. Plots were 10 by 35 feet, arranged in a randomized complete block design with four replications. Control of kochia, Palmer amaranth, and Russian thistle were visually determined on June 9 and July 6, 2016, which was 15 and 42 days after the May 25 application, respectively.
