Proper Use and Handling of Glyphosate in Plant Nurseries

A NEW publication by Shawn T. Steed and Robert H. Stamps at The University of Florida/IFAS

—————————-

Glyphosate is the largest-selling single crop protection chemical worldwide (Woodburn 2000) and the most used herbicide in the nursery industry in the United States (Norcini et al. 1996). It is used for postemergent control of vegetation. Glyphosate is an extremely effective chemical that controls a broad spectrum of annual and perennial grasses, broadleaves, and sedges. This herbicide acts as an inhibitor of an enzyme that leads to the formation of several essential amino acids required for normal protein synthesis. Glyphosate has the ability to spread throughout the plant and concentrate in the growing regions where these amino acids are most needed for new growth. As a nonselective, translocating herbicide, it is easy to cause unintended damage to desirable vegetation if this product is used incorrectly. This publication outlines the proper use of glyphosate for plant producers and their employees.
