Nematode update

     I was hoping I had good new concerning the nematode problem we have been dealing with the last few years.  I have been using a newer nematicide called Nimitz to control the Lance nematodes we have in our greens.  After 2 applications we still have damage from the nematode.  I ran a test on one of the thin areas and Lance nematodes were 5 times over the threshold.  Dr. Miller from University of Missouri said he has not seen any samples that high.  So it looks like the new product is not working.  The good news is days are getting shorter and temperatures are not as hot.  We should get through the rest of the season with minimal damage.  We have 10 greens with some sort of damage.  The round patches dying is where the nematode counts are the most severe.  I do have one more application of Nimitz to apply.  I can only hope we get some sort of control from it.  We will put it down after we aerate greens in 2 week.  The greens I applied Nemacur to are doing much better than the greens that did not get any.  Greens 4, 5, 6, 10, 11, 12, all got Nemacur, with holes 4, 5, and 11 getting two apps of Nemacur.  Nemacur is no longer available and I do not have anymore.  Going forward we will be using a product called Nortica this fall and next spring.  Nortica is a Bacteria that protects the roots from Nematodes. It does not kill the nematode It keeps them from feeding on the roots.  All trials have been very good from the University of Florida.  Dr. Crow said it does work.  It is a preventative control and has to be applied before you have problems.  Dr. Crow also has a new trial out on Lance nematode control.  Hopefully we get a new nematicide out the trial that will control this pest.
