    If you go to the DowAgro and site and look at the label for Dimenson it plainly states not to use this product on Tifgreen 328 or 'undesireable turfgrass injury may occur'.

    But on the Lesco branded bag of Dimension I picked up from JDL this warning is nowhere to be found. Shouldn't it be? Or is there some difference in the product or something else I'm not understanding.

    Thanks-

    Don't do it. Dimension will prune the roots of bermuda, especially Tifgreen and Tifdwarf maintained at a low height of cut. In fact, I do not normally use preemergent herbicides on bermuda. Weeds are kept out by fertilizing adequately and mowing with a reel mower as often as possible. On a low growing grass that spreads by stolons, rotary mowers tend to suck up and cut off stolons trying to anchor into the soil, thinning out the lawn, encouraging invasion by weeds.

    Greendoctor.....does that include common seeded Bermuda cut at 2" (with a rotary) or is that geared more toward a hybrid or sod? The reason I ask is the local Lesco where I purchased my common Bermuda recommends Dimension included in the regular fertilizing schedule.

    Good advice about the fertilizing and mowing, I wish I could follow it (I do try!) but circumstances dictate otherwise. I called the guys at JDL, but they had no good answers as to why the warning was not posted on the bag which is why I thought I would ask here.

    I wonder what the difference is between say, 328 and 419, that makes one susceptible to injury and the other not so much. Any idea's? Or where one might look to find the answer?

    Thanks

    Avguy- The Dow Agro label only advises caution when applying Dimension to Tifgreen 328, other varieties of bermuda, common and hybrid, are listed as tolerant.

    The Dow Agro label I was reading is for Dimension 2EW, a liquid. The Lesco product I've seen is a dry granular, 0-0-7, and that label lists no such restrictions, but they both contain the same active ingredient, dithiopyr.

    I'm curious as to why one could cause problems and the other maybe not.
