Prevent Goosegrass and Crabgrass This Season with Goosegrass/Crabgrass Control

Posted Tony Goldsby, Agronomist on February 15, 2019


Goosegrass and crabgrass are grassy annual weeds which germinate in the late spring and throughout the summer.  They can be especially problematic in low cut turf areas such as putting greens and collar approaches.  

The best approach to preventing an infestation of these problematic weeds is with an application of a pre-emergent product like The Andersons Goosegrass/Crabgrass Control.

Goosegrass/Crabgrass control is a combination of Bensulide and Oxadiazon for use on golf course tees, fairways, and greens. This product provides season-long control of goosegrass and crabgrass in bermudagrass, zoysiagrass, tall fescue, bentgrass, and perennial rye. 


Product Information

Product Code: AGC8656.2
SGN: 80
Bag Weight: 28.8 lbs.


How To Apply

Even the most experienced turf managers can experience issues if they do not properly read the label when applying this product.  Environmental conditions and turf leaf blade moisture play a crucial role in the efficacy and potential turf injury, so please take all necessary precautions when applying.

When should I apply?

For maximum control, Goosegrass/Crabgrass control should be applied prior to soil temperatures reaching 55 degrees at a four inch depth. Geographic-dependent factors such as temperature and annual rainfall amounts impact herbicide performance significantly, so please consult the label to determine your proper application timing. 

To reduce the potential for yellowing or injury on established greens, we recommend applying only the half-rate to completely dry foliage. You can then make a subsequent application at the half-rate approximately 10-14 days later. The half-rate applies 1.31 lbs of product per 1,000 sq. ft.

Preparing for the Application

Fill your hopper with the amount of Goosegrass/Crabgrass Control product needed for your application area. Per the label directions, if you wish to apply a half-rate with full-width coverage, you need to have the spreader setting at G with your helical cone set at 9. The half-rate provides .75 lbs oxadiazon and 3.0 lbs bensulide per acre.

If you need more information on how to calibrate your spreader, please refer to our “Prizelawn ARC 1 spreader calibration” video. 

Now that your spreader is filled, it is time to put your flags out for making the application.  Make sure to place flags nine feet apart to represent your spreaders effective swath width. This product needs to be applied from the edge of one effective swath width to the next effective swath width. This is marked by the flags you placed marking the edges.

Applying the Product

Begin walking, making sure to keep a steady gate approximately 3 mph while aiming towards the center of the two flags representing the swath width.

For heavy goosegrass infestation, a full-rate of the product followed by a half rate application 30 days later may be necessary. However, when making this type of application to creeping bentgrass greens, be cautious to not over-apply during the second full-rate application. Over-application can cause significant turf thinning or damage.


Best Practices for Application

Here are a few best practices for applying Goosegrass/Crabgrass Control to ensure no turf injury occurs.

1) Apply to dry foliage.

2) Water-in immediately following product application.

3) Do not apply this product to thin or stressed turfgrass.

4) Avoid applying this product following aerification. Wait seven days prior to applying.

5) Avoid applying this product when temperature exceeds 80 degrees.

6) Only use a helical cone spreader from The Andersons to apply. Make sure cone is set to 9.

7) Calibrate spreader prior to use. If unsure how to do this, please refer to our video entitled, “Prizelawn ARC 1 spreader calibration”.

8) Use flags or another marking system to ensure correct swath width.
