Weed Prevention with Buffalograss

Proper turf management practices can prevent many of the common weeds. Avoid frequent watering, over fertilizing, and scalping as these practices promote weed growth and put your buffalograss at a competitive disadvantage. Unfortunately, good management practices only reduce the weed competition and do not eliminate them. Hand weeding is always an option but is very time consuming and labor intensive. Herbicides are commonly used to aid the turf manager in promoting a healthy weed-free turf.

Weedgrass competition is one of the most common factors limiting the rapid establishment and spreading of a new buffalgrass stand. An application of Drive 75DF Herbicide, a selective post-emergence herbicide will do a good job of limiting weedgrass competition. This application should be made in the 3rd or 4th week after planting. As with any pesticide ALWAYS READ AND FOLLOW THE MANUFACTURER’S LABEL PRIOR TO USE.

When used in accordance with the manufacturer’s label, these products are safe and very effective. If you are uncomfortable or inexperienced in the use of pesticides it is best to have the products applied by a licensed and reputable lawn care service. For those who want to do their own application the following is a brief outline of the products available and their intended use.
