Isoxaflutole, mesotrione, and chloroacetamides on grass and waterhemp

摘要

The objective of this study was to evaluate control of grass and common waterhemp with isoxaflutole, mesotrione, and chloroacetamides. This study was conducted at the Bradford Research and Extension Center near Columbia, MO. The soil was a Mexico silt loam with a pH of 5.8 and 3.1 percent organic matter. Northrup King 6800 LL was planted 1.5-inch deep on May 3 in 30-inch rows. Treatments were arranged in a randomized complete block design with four replications of 5 by 35 feet plots. Herbicide applications were made with a CO_2 backpack sprayer equipped with XR8002 flat fan nozzles.
