WEEDS
Best Management Practices:
Spurges
Spotted spurge is a warm season, annual broadleaf weed that has prostrate branched stems with red-spotted, opposite leaves. Its stem contains a “milky sap” and very similar but will not have the spotted leaves. Being a warm season, annual plant means that it only comes back from seed each year, usually germinating in the spring season and possibly into the summer.
Spurge germinates in the spring from seed. Pre-emergent herbicides will to kill the seed. Normally, an application of a pre-emergent in late February will work well. This weed may germinate into the summer and a second pre-emergent application in the month of May is required.
There are several pre-emergent herbicides that can be used to control spurge in most turfgrass sites including Bermudagrass, St. Augustinegrass, Zoysiagrass, and Buffalograss. Examples include Pendulum 2G or Anderson 11-3-11 (Pendimethalin) and Balan 2.5 G. Post emergent herbicides can be effective if used when the spurge is very young/immature and actively growing. Effective post-emergent herbicides include: Weed Free Zone and Trimec Southern work very well if used in the correct manner.
Make sure you READ THE LABEL very carefully prior to application. It may require multiple applications to obtain excellent control with these post-emergent products. CAUTION: Make sure you read the labels carefully for the tolerance level of your specific turfgrass for all herbicides.

Field Sandbur (Grassbur)
Field sandbur, also known as “grassbur”, is a warm season, annual grassy weed that normally has "reddish" stems at the base of the plant, sandpapery but smooth leaves, and a spiny bur in its seed head. Being a warm season, annual plant means that it only comes back from seed each year, usually germinating in the mid/late spring season. Grassbur also creates havoc in lawns because it will germinate seeds throughout the summer as well.
Pre-emergent herbicides work by killing germinating seeds from weedy plants like grassbur. Timing of application is critical so as to have a herbicide barrier in place at germination. Normally, an application of a pre-emergent in late February or early March will work well. Remember, though, that this weed may germinate into the summer—so, a second pre-emergent application in early May is warranted.
There are several pre-emergent herbicides that can be used to control grassbur in most turfgrass sites including bermudagrass, St. Augustinegrass, zoysiagrass, and buffalograss. Examples include: Pendulum 2G or Anderson 11-3-11 (Pendimethalin) and Balan 2.5 G .
If you have grassbur that escapes the pre-emergent or you do not apply a pre-emergent, you may need to apply a post-emergent herbicide. These herbicides can be effective if used when the grassbur is very young/immature and actively growing. Examples of effective products are Celsius and Pastora. They work very well together if used in the correct manner. It may require multiple applications to obtain excellent control with these post-emergent products. CAUTION: MSMA can only be used on bermudagrass and zoysiagrass turf sites --- NOT ST. AUGUSTINEGRASS! Image, on the other hand, can be used on St. Augustinegrass, but may not perform as well as MSMA. So make sure there is no wind to avoid drift and set your sprayer to where the droplet size is much larger (not a fine mist).

Best Management Practices:
Goosegrass
Goosegrass can also grow in highly compacted soils like walkways and parking lots. In fact, goosegrass growing in turfgrass sites is usually a sign of heavy compaction. It is a warm season, annual grassy weed that has a white to silver color at the crown/base, individual plants/tillers originating from the base and a seed head with spikelets. Being a warm season, annual plant means that it only comes back from seed each year, usually germinating in the spring season.
Goosegrass begins its life by germinating in the spring from seed. Pre-emergent herbicides work by killing germinating seeds from weedy plants like goosegrass. Normally, an application of a pre-emergent in late February to early March will work well. Remember, though, that this weed will germinate into the summer—so, a second pre-emergent application in May will be warranted.
There are several pre-emergent herbicides that can be used to control goosegrass in most turfgrass sites including bermudagrass, St. Augustinegrass, zoysiagrass, and buffalograss. Examples include: Pendulum 2G or Anderson 11-3-11 (Pendimethalin) and Balan 2.5 G .
If you have goosegrass that escapes the pre-emergent or you do not apply a pre-emergent, you may need to apply a post-emergent herbicide. These herbicides can be effective if used when the goosegrass is very young/immature and actively growing.
CAUTION: Read the labels carefully for the tolerance level of your specific turfgrass for all herbicides.

Best Management Practices:
Henbit
Henbit is a cool season, annual broadleaf weed that has greenish to purplish four-sided stems. Its egg-shaped leaves surround the stem and will have toothed margins with prominent veins on the underside. The flowers of Henbit are reddish to purplish and may have dark colored spots on the lower petal. Henbit comes back from seed each year, usually germinating in the fall season and possibly into the winter.
Henbit begins its life by germinating in the fall from seed. Pre-emergent herbicides work by killing germinating seeds from weedy plants like henbit. Normally, an application of a pre-emergent in early/mid September will work well. This weed may germinate into the winter—so, a second pre-emergent application in November may be warranted.
There are several pre-emergent herbicides that can be used to control Henbit in most turfgrass sites including Bermudagrass, St. Augustinegrass, Zoysiagrass, and Buffalograss. Examples include Pendulum 2G or Anderson 11-3-11 (Pendimethalin) and Balan 2.5 G.
If you have Henbit that escapes the pre-emergent or you do not apply a pre-emergent, you may need to apply a post-emergent herbicide. These herbicides can be effective if used when the Henbit is very young/immature and actively growing. Some examples of effective post-emergent herbicides are Weed Free Zone, and Trimec Southern. They work very well if used in the correct manner. It may require multiple applications to obtain excellent control with these post-emergent products. CAUTION: Make sure you read the labels carefully for the tolerance level of your specific turfgrass for all herbicides.

Best Management Practices:
Hop or Bur-Clover
Bur and Hop Clover are cool season, annual broadleaf weeds that have round stems with leaves made up of three leaflets. These leaflets are somewhat oval or egg-shaped and the tops of the leaves are normally rounded with a very small indention in the middle. The flowers of hop and bur clover are numerous and yellow in color. Being a cool season, annual plant means that it only comes back from seed each year, usually germinating in the fall season and possibly into the winter.
Pre-emergent herbicides work by killing germinating seeds from weedy plants like bur or hop clover. Normally, an application of a pre-emergent in mid-September will work well. Remember, though, that this weed may germinate into the winter—so, a second pre-emergent application in November may be warranted.
There are several pre-emergent herbicides that can be used to control bur or hop clover in most turfgrass sites including Bermudagrass, St. Augustinegrass, Zoysiagrass, and Buffalograss. Examples include: Pendulum 2G or Anderson 11-3-11 (Pendimethalin) and Balan 2.5 G.
If you have bur or hop clover that escapes the pre-emergent or you do not apply a pre-emergent, you may need to apply a post-emergent herbicide. These herbicides can be effective if used when these winter clovers are very young/immature and actively growing. Do not wait until late winter when these annual broadleaf weeds are flowering and mature. Examples of effective post-emergent herbicides include: Weed Free Zone and Trimec Southern. It may require multiple applications to obtain excellent control with these post-emergent products. CAUTION: Make sure you read the labels carefully for the tolerance level of your specific turfgrass for all herbicides.
