|Clear pattern of disease on approaches Jan 5 2015|
|Typical infection in previous years|
A have also applied this same plan to my tees with similar results. The last time the tees were cut was Nov 1 2014 and the iron and primo was applied on Nov 4 2014. There is just now some fusarium starting to appear. Perhaps I stretched the application interval too far. I plan on making another iron and primo app to the tees in the next week as well. Hopefully it's not too late.
The total cost of this program has been about $25 for iron and $25 for the primo on approaches and green surrounds. The price for the tees is relatively the same. Not bad considering a fungicide application would easily cost 10x this.
Despite the cool wet weather I have never seen so little fusarium on my tees and approaches at this time of year. I hope that it is a result of the iron and Primo applications. Time will tell.
As for my greens......They aren't that bad but it has been a constant battle this winter. Maybe I should try some iron on them too? I need to bring back the good old check plot to get a better idea of what is really happening out there.
