How to Kill Common Purslane
Controlling Common Purslane is easy if you have a thick and fertilized lawn. Common Purslane is very uncommon in fully developed lawns and will be choked out by the grass when it starts growing. You obviously can pull common purslane if there are only a few of this weed in your yard, but below there are some pre-emergent and post-emergent chemical remedies for common purslane.
Pre-emergent method: To kill common purslane before it germinates, put down Dimension 2EW Herbicide either in liquid form or included in a granular fertilizer. This must be done within a certain amount of growing degree days. The optimal time to put this down in Michigan is between April 15 and May 1. Dimension will not only keep common purslane from growing but will stop many other annual weeds including crabgrass.
Post-emergent method: To kill common purslane after post-emergent use Dicamba, MCPP, MSMA, and 2,4-D. A popular herbicide that contains these ingredients is:
Speedzone Herbicide: Speedzone works on both cool-weather and warm-season grass. Fall is the best time to spray common purslane with Speedzone. Evidence of injury may be seen within a few hours spraying it. It will take anywhere from 5 to 10 days for the weed to die. For you own safety, make sure you wear Nitrile Chemical Resistant Gloves, and use a backpack sprayer such as the Chapin Pro Series 4 Gallon Backpack Sprayer.
If you want to go the with a cheaper option, buy Trimec 992 and spray the common purslane twice over a 10 day time period for the best results. Common Purslane has an outside waxy layer that makes it difficult for herbicide to be soaked in. Once the herbicide makes it through this layer it is easy to kill. To stop the herbicide from sliding off the plant and not soaking into it, mix a non-ionic surfactant so the herbicide will stick to the plant.
Speedzone and Trimec herbicide are both selective herbicides. These herbicides will also kill other broadleaf weeds, but will not kill your lawn. It is important that you do not use a herbicide that contains the ingredient Glyphosate such as Roundup. This will kill your lawn.
