    we have never used pre-emergent on any of our commercial accounts so I need to learn more about them. What exactly do they do and how are they spread (granules or spray)? What brands do you recommend and when (time of the year) do you apply them to turf/ beds? thanks

    Preemergent to turf grass is completely different vs. preemergent to landscape beds for this climate. Require more information as to what noxious weeds you wish to control, plant material treated, and irrigated or not.

    Primarily turf, irrigated, both Bermuda and St Augustine. Any info would be great

    Rostar is the only pre-emergent that doesn't cause chemical pruning. Yep it is not cheap.

    Hi Daferg,

    Here is a great article to read.

    Why? How? When? Where? & What?


    Pre-emergent herbicides represent an easier and more economical approach to weed control versus post-emergent approaches. Controlling weeds before they appear eliminates the negative aesthetic of dead grass and weeds treated later in the year. "

    That's an understatement! I've seen university studies saying how great Ronstar is, but I can't imagine a situation where I would want to pay 3 to 4 times the price of Dimension for something that would be only very marginally better.
