Weed Control Efficacy of Two Kinds of Herbicide and Their Mixture in Container Seedling Breeding of Loropetalum chinense var. rubrum

A weed control experiment was conducted for Loropetalum chinense var. rubrum container seedlings with 24% oxyfluorfen EC, 108% HaloxyfopPmethyl EC, and the combination of 24% oxyfluorfen EC and 108% HaloxyfopPmethyl EC. The results showed that the control effect of 20 mL/667 m2 of 24% oxyfluorfen EC 30 days after application was 90.3% out of the plants, and 87.8% by the fresh weight. While the control effect of 20 mL/667 m2 of 24% oxyfluorfen EC 40 days after application was 91.7% out of the plants, and 91.6% by the fresh weight. The weed control effect of 20 mL/667 m2 of 24% oxyfluorfen EC was better than that of the other two types of herbicide. It was also safer to the container seedlings of L. chinense var. rubrum, so it should be further extended to larger area.
