Chemical Weed Control
The main chemical used by the Louisiana Forestry Commission is mineral spirits, or light herbicidal oil. The one we use is naptha and it has an aromatic hydrocarbon content of about 15 percent. No plant is completely resistant to injury from this herbicide, but there is a great tolerance range between plant species. It happens that some of the plants with a high resistance are those cultivated as nursery stock, such as most conifers and sweetgum. Luckily, some of the low resistant plants are those we want to get rid of, such as crowfoot, bermuda, and Johnson grass.
