Helminthosporium Pays Us A Visit Again

Leaf Spot by Eric von Hofen
Almost over night we see the results of Helminthosporium on our TifEagle greens. This is the first time in a year we have seen any signs from our little friend here in Miami. I wrote a similar post on this disease almost a year ago to date. Last year we had record cold temps that brought on the signs of the disease. This year we have had a month of well above temps with light rains that have kept the soil around 80 degrees. This was just enough to increase the pressure of the disease and for us to see the damage. I have started a program of applying fungicides on a 14 to 21 day rotation. I will use Fore, Insigna and Daconil for control and prevention of the leaf spot this winter. It has been 16 days since my last fungicide application so I’m not surprised to see the spots pop up. I spray my greens every friday with a light Harrells fertilizer package so adding fungicides will be easy to do. I will keep you updated this winter on the progress on the control of Helminthosporium. I see a connection between the amount of sun, rain fall and soil temps when the Helminthosporium shows up. Let me know what your seeing on your golf course.
