How can you tell the difference between Goosegrass and crabgrass?
The shoots from goosegrass are green, but they have a base that is white or silver. This whitish or silver area at the bottom of the stems and in the center are one of the distinguishing features of goosegrass. The shoots are a lighter green, but the leaves are dark green. It is darker than crabgrass, and its coloring helps people identify it.
Is goosegrass an annual or perennial weed?
One of these weeds that is easy to confuse is goosegrass (Eleusine Indica) which is a summer annual weed that tends to start germinating once the temperature of the soil reaches around 60 degrees. Did you know a single goosegrass weed can produce up to 50,000 seeds?
What does goosegrass look like in Indiana?
Goosegrass produces seedheads from July to September in Indiana. The seedheads are similar in appearance to crabgrass but the seeds are slightly larger than crabgrass seeds and the spikes on the seedhead are often described as being “zipper-like” in appearance.
Is crabgrass an annual or perennial?
Crabgrass (Digitaria spp.) and goosegrass (Eleusine indica) behave as true annuals in the northeastern United States (Figure 1). These plants germinate in the spring and grow rapidly throughout the summer as warm-season (C 4) plants, mature in late summer, and produce seed before dying at the first frost in autumn.

What grass is similar to crabgrass?
Tall fescue is a wide-bladed grass that grows more quickly than Kentucky bluegrass. Like crabgrass, it grows in a clump, but the grass blades usually stand up tall. The grass blades of tall fescue are very wide and coarse, and the base of the plant is usually red.
Should I pull goosegrass?
If you see goosegrass weeds begin to grow in your lawn, you can pull the weed by hand or by using a small trowel. It is easiest to remove the weeds when the soil is damp, such as after rain. Be sure to remove the goose grass roots as well as the leaves and stems to prevent the weed from growing again.
How do you deal with goosegrass?
If you are using a spray application for control of goosegrass in lawns, apply it on a windless day to prevent drift that can kill non-target plants.

How does goosegrass spread?
Goosegrass is commonly found throughout much of the continental United States. These perennial grassy weeds can germinate and spread from seeds, but they also produce a root structure (tubers, bulbs or corms) that can birth new weeds from your lawn's surface (using stolons) or from underground (using rhizomes).
What kills goosegrass in St Augustine?
The best way to get rid of goosegrass is to use a post emergent herbicide. By the time you know it's a problem, it will likely be too late for a pre-emergent herbicide, so a selective post emergent herbicide is your best option.
What does goosegrass look like?
Goosegrass forms a pale green matlike clump with flattened stems that grows in a low rosette. Stems are somewhat fleshy at the base. The mature plant can spread to about 2-1/2 feet (80 cm) wide. The leaf blades are nearly hairless, except for long hairs on the blade bases, collars, and/or upper sheath margins.

How to identify goosegrass?
The best way to identify it is by the whitish stems at the base that are extremely flattened. Besides being just plain ugly, goosegrass is also susceptible to viruses that cause Sugar Cane Mosaic.
What happens when crabgrass dies?
When crabgrass dies in the fall, it leaves large dirt spaces in the lawn which become prime areas for seeds to germinate the following season. Contact a professional, certified pest control or lawn maintenance company to diagnose your turf issues and get you on a weed-eradication plan.
What kind of weeds does Artistree have?
You have goosegrass and crabgrass, and they are hard to distinguish unless you have a trained eye. ArtisTree deals with these pesky weeds a lot when managing the maintenance of a new community, so you’ve come to the right place.
Is crabgrass a virus?
On the other hand, crabgrass is distinguished by long, finger-like wide blades that lie on the ground with tips ascending. It thrives in thin, weak lawns that are lightly watered, under fertilized and poorly drained.
What is crabgrass?
Smooth and large crabgrass ( Digitaria ischaemum and D. sanguinalis, respectively) are the most common crabgrass species found in the northeastern United States (Figure 2). Crabgrass has a rolled stem (rounded vernation) and lime green, coarse-textured leaves. It typically has a prostrate growth habit, spreading out along the ground. Crabgrass seedheads appear finger-like with spikes (racemes) arising from different points at the top of the stem (Figure 3). The leaves and leaf sheaths of large crabgrass are typically covered in dense hairs, while those of smooth crabgrass are hairless (glabrous) and purple at the base. In the northeastern and mid-Atlantic regions, smooth crabgrass is more prevalent than large crabgrass.
How to prevent crabgrass and goosegrass?
A dense stand of turfgrass is an effective way to prevent crabgrass and goosegrass. Supply adequate nitrogen fertility to maintain a dense canopy of desirable turfgrass by applying nitrogen fertilizer in early autumn and, if needed, in spring when cool-season grasses are more competitive than these warm-season weeds.
What herbicides are effective for crabgrass?
Dithiopyr, prodiamine, and pendimethalin are equally effective for crabgrass control at the rates discussed below; goosegrass control varies by product. Older herbicides such as benfin (Balan), benefin + trifluralin (Team Pro), DCPA (Dacthal) are less effective than herbicides listed below and are not discussed.
How to reduce crabgrass?
Research shows that mowing at the highest height recommended for your particular turfgrass species can significantly reduce crabgrass infestations compared to a low mowing height. Combining a higher height of cut with proper fertilization will create a dense turfgrass canopy that will shade the soil and create a more difficult environment for weed seedlings to survive.
What is the difference between smooth crabgrass and large crabgrass?
Smooth crabgrass and large crabgrass. Notice the hairs along the stem and leaves of large crabgrass, while the smooth crabgrass has a purple stem and is hairless.
Why is it not desirable to water grass?
Light and frequent irrigation throughout the growing season is not desirable as it keeps the soil surface moist and encourages weed seedlings to survive and grow. Desirable turfgrasses are more competitive under deep and infrequent irrigation since these grasses typically have deeper roots than crabgrass or goosegrass seedlings.
When does crabgrass germinate in New Jersey?
Crabgrass typically germinates mid- to late April in central and northern New Jersey and early to mid-April in southern parts of the state. Forsythia is an excellent phenological indicator for crabgrass germination. When forsythia is in full bloom, crabgrass pre-emergent herbicides should be applied as soon as possible. Crabgrass will germinate earlier in bare soil, particularly on south-facing slopes and near hardscapes, than in areas with good turfgrass cover. Goosegrass typically germinates 3 to 4 weeks after crabgrass.
Is crabgrass a tropical grass?
Both crabgrass and goosegrass are tropical grasses that like hot, dry conditions and climates. And like most weeds, they are opportunistic and gain a foothold in turf when turf is stressed. So during summer months where cool-season turf is growing, these weeds have an advantage.
Can you use preemergence or postemergence herbicides on crabgrass?
You can control crabgrass and goosegrass pre-emergently or post-emergently. A pre-emer gence herbicide targets the weed as it is germinating, which means you’ll treat before you actually see the weeds. Post-em ergence herbicides are formulated to kill weeds that have already germinated.
How is goosegrass different from crabgrass?
Furthermore, goosegrass can be distinguished from crabgrass by its leaf arrangement. Goosegrass leaves are folded in the bud (emerge from the sheath as folded) whereas crabgrass leaves are rolled in the bud (emerge from the leaf as rolled).
What is goosegrass?
Identification: Goosegrass is a prostrate growing summer annual grass which form s a mat-like rosette. Its flattened leaf sheaths are typically a white to silver color, especially at the base of the leaf sheath. Because of this coloration and its similarity to crabgrass some call it silver crabgrass.
What is the best preemergence herbicide for goosegrass?
Chemical control: Goosegrass is best controlled with preemergence herbicides. Herbicides that contain oxadiazon (Goosegrass/Crabgrass Control, Ronstar, Oxadiazon) are the most consistent products for preemergence control of goosegrass.
When does goosegrass seedhead come out?
Goosegrass produces seedheads from July to September in Indiana. The seedheads are similar in appearance to crabgrass but the seeds are slightly larger than crabgrass seeds and the spikes on the seedhead are often described as being “zipper-like” in appearance.

Introduction and Identification
Managing and Controlling Crabgrass and Goosegrass
- A dense stand of turfgrass is an effective way to prevent crabgrass and goosegrass. Supply adequate nitrogen fertility to maintain a dense canopy of desirable turfgrass by applying nitrogen fertilizer in early autumn and, if needed, in spring when cool-season grasses are more competitive than these warm-season weeds. Research shows that mowing at the highest height recommend…
Mechanical Removal
- Both crabgrass and goosegrass are annual plants that cannot regrow if the crown (basal growing point) of the plant is removed. Crabgrass has a fibrous root system and the crown can be easily removed by hand or an upright weeding device such as Hound Dog® or Weed Hound®. As crabgrass matures it can also root at nodes on stems growing along the groun...
Herbicide Options
- In areas with a history of infestations that cannot be managed with cultural practices and mechanical removal alone, herbicides are an effective and economical option when applied at the proper time and rate. Goosegrass more so than crabgrass has a history of developing herbicide resistance if herbicides with the same mode of action are used in several consecutive years. Rot…
Pre-Emergence Herbicides
- Especially in areas with a history of moderate to severe infestations, pre-emergence herbicides are more economical and effective than post-emergence herbicides. Most pre-emergence herbicides must be applied and watered into the soil beforethe weed seed germinates to be effective. After irrigation, these herbicides are adsorbed to organic matter in the surface ¼- to ½ …
post-emergence Herbicides
- In areas with a history of moderate to severe goosegrass or crabgrass infestations, it is more economical and effective to rely primarily on pre-emergence herbicides and use post-emergence herbicides where plants "escape" the pre-emergence herbicide. Relying exclusively on post-emergence herbicides is only recommended if pre-emergence herbicides are not an option or in …
Organic Herbicides
- Organic herbicides are not as effective or consistent as synthetic herbicides. In an organic system, utilizing proper cultural practices is of the utmost importance. This includes mowing at the highest recommended height (typically 3 to 5 inches) for the turfgrass species in the lawn, as well as the proper fertilization, irrigation, and seeding discussed earlier in this publication.
Conclusions
- Effective crabgrass and goosegrass control requires the right combination of turfgrass management aligned with proper herbicide selection and application. A healthy and dense turfgrass canopy will reduce reliance on herbicides. Knowing the weed history of a particular site can help you develop an economical and effective strategy. For example, on a site with a history …
