Herbicides, an Important Component of the Weed Control Program at Oklahoma State (Norman) Nursery

Ten herbicides were evaluated at the Oklahoma State Nursery for weed control on raising one-year seedling nursery beds. Phytotoxicity of DCPA, napropamide, oxyfluorfen, bifenox, and a napropamide plus bifenox tank mix was studied for three years on spring-sown Austrian and loblolly pine, and fall-sown eastern redcedar. Bifenox (on loblolly and Austrian pine) and oxyfluorfen (on Austrian pine) reduced germination when applied at time of sowing, but not when applied post-germination. Time required to hand weed nursery beds was reduced by 80-87 percent when using the above herbicides applied at sowing time alone or with a second application four to six weeks later. Over $4,500 per acre of seedbed could be saved by using herbicides over hand-weeding at the Norman Nursery.
