No kind words for September

The average high for yesterday (Sept 1) is 87. We beat the old record (107) with a high of 108. Yuck. I kept thinking "Just wait til September... just wait til September." Well, September, I have some special words for you, but I'm too much of a lady to type them in this public blog. Click on the image below to zoom in on our summer-of-fun. This particular data is from here in Manhattan.




This time of year can be marked by extremes. The record lows are in the 40's, but there have been triple digit record highs almost all through September. Wild mood swings.

We had a severe brown patch epidemic in early/mid August, and brown patch reached about 40% severity in the untreated plots. All the programs and the two Velista treatments held the disease to 0%.

Dollar spot pressure has been fairly low but with cooler temperatures I suspect it will flare up in the next week or two and probably though most of September. I’ll post some details later on.
