Chemical Control of Weeds and Grass in Southern Pine Nurseries

A 2-year study was completed in 1961 by the Texas Forest Service on the screening of chemicals for weed and grass control in nursery seedbeds. The three general types of treatments tested included pre-seeding, pre-emergence, and post-emergence--or stated another way, chemicals were applied before and after sowing of pine seed. The term "pre-emergence" and "post-emergence" apply to treatments after the pine seed are sown but respectively before and after the seed germinated. Techniques evaluated in this study included variable spray volumes, nozzle pressures, optimum application dates for treatments, toxicity limitations to the seedling crop, and cost-benefit ratio.
