Effects of Long-Term Preemergence Herbicide Use on Growth and Yield of CitrusMcCloskey, William B.; Maurer, Michael; Wright, Glenn; Department of Plant Sciences; Maricopa County Cooperative Extension (College of Agriculture, University of Arizona (Tucson, AZ), 1997-11)The effects of several preemergence herbicides at various rates were tested on bearing Redblush' grapefruit trees and non-bearing Navel orange trees. Some of the preemergence herbicides caused foliar injury symptoms on the trees including Hyvar X Diuron, and Krovar I although they did not cause significant yield reductions in the short time period of this experiment. Several herbicides including Solicam, Surflan, and Prowl did not cause foliar injury or reduce yield and provided good weed control for various lengths of time. The Prowl treatments provided the longest period of weed control in the experiment on bearing grapefruit trees.
