Prodiamine effects on zoysia and burmuda Cancel The title field is required!

   I've been applying prodiamine at 1.25lbs/A in the spring for crabgrass pre-emergent. I am located in the mid-west in the transition zone. I have had some peers telling me that I need to stop use of this product because it has root pruning and prevention on my zoysia and bermuda. The only thing I can find on the label similar is this: "Newly sprigged or plugged bermuda stolon rooting may be temporarily retarded". I believe two half rate applications lessens the negative affects on my zosia and bermuda and would have a greater control on crabgrass germination.
   
   1) Is there a interval for post prodiamine application warm-season sodding?
   2) Does anyone have experience with prodiamine causing zoysia or bermuda sod to not root down while using a comparable rate annually?
   3) What other options for crabgrass prevention are there with comparable effectiveness and cost?

   Nick,
   
   You should be fine with Prodiamine. Ronstar or dimension are other alternatives. Your Prodiamine rate seems really high if are speaking of lbs. of ai. .65 lbs. ai should be plenty.

   We had a yard once that was stripped of the old St. Augustine, then sprayed with Round-up and prodiamine before sodding with Empire Zoysia. After about three months, there were no roots tacking into the soil. Come to find out, a the pest control company admitted to using prodiamine before sod. They ended up removing the sod, tilling the soil, and resodding.
   
   Although I would be cautious using prodiamine with new turf, the same can be said about turf emerging from dormancy. It can prevent tacking down of new growth and runners, and a better alternative would be something like Ronstar in the spring. That being said, I know of many Superintendent's that have successfully applied prodiamine in the spring with no lingering issues as this was the only option due to budget constraints.

   We have found that applying Prodiamine at 1/2 rates, smaller intervals has had a much better effect on our turf healthy, rooting and density.

   Biggest issue most speak about are already weakened areas from traffic, ice, extreme cold and shade. There are no other cheaper alternatives that don't have the potential for rooting issues.
   
   One of the things you could do is to throw in Ronstar every couple of years into the mix or only apply it to your weakest fairways to reduce the chemical impact as well as the financial cost.
   
   SInce I have reduced most of my fairway inputs over the years, I've chosen to go with the best product on my fairways for Pre-M since they are the largest fine turf area that I treat at our facility. I've reduced rough applications to use the best product on my fairways.

   Joe, I was checking out the label and rates, what formulation do you use and what rate to get that season long control. I noticed the label mentioned the higher rate to control crab, I wonder if I went one application of Ronstar at the low rate and come back with something else at a low rate. Of course I haven't priced those options yet.
   
   Thanks!

   Mel,
   I don't get any break with Ronstar, keeps goose and crab out. I rarely ever use high rate. Usually 2-2.4# active but you have a longer season than us so probably would have to up the amount to the higher rate. I am using Echelon this season on tees because of kylinga issues. Split apps April/May.
