Greg from Jackson, Ms writes,

What is the best month to apply Pendulum 3.3 EC to control Sandspur for next year?

I have a St. Augustine yard in Jackson Mississippi with Sandspur.


Most regions recommend treating Sandspur with a pre-emergent in February. Unfortunately, Pendulum 3.3 EC is not labeled to treat sandspur and we are not aware of a pre-emergent that we carry that is labeled to control Sandspur. You can use a product called HI Yield Atrazine Killer which is a post-emergent that is labeled to treat Sandspur and can be used in St. Augustine lawns when weeds are actively growing.
