Week 17 we sprayed Greens at a preventative rate of fungicide. This time of year we will be spraying them every 14-20 days with a fungicide to prevent any disease breakout. We also sprayed an insecticide on them. There have been many reports from local Universities stating that insect damage is expected to be extreme this year. Week 18 I hope to get all the Zoysia turf treated with insecticide (weather permitting). The photo is of an irrigation break that took a lot of digging to find. The far hole is where the water surfaced but the near hole is where the break actually was. It was a frustrating break but it is now fixed.
Now that the temps are in the high 80's and 90's it is a perfect time to push the Zoysia turf. Zoysia turf loves heat and sunshine and some of our problem tees are in the shade much of the day (#1, and #9 on the River Course and #2, and #8 on the Rock Course). So every 2-3 weeks we will be aerifing these tees with a solid tine and we will also be pushing the fertilizer. Hopefully by Fall we will have a healthy stand of turf.
Week 15 was another very busy week. We aerified all the greens with a bayonet tine. June, July, and August are the three months when venting the greens is extremely important, so we plan on aerifying the greens with a venting tine once during these months. The benefits are huge and they do not interfere with the playability of the course. Also this week we fertilized, verti-cut and topdressed the greens as well as sprayed a wetting agent, preventative fungicide, preventative insecticide, and a growth regulator. All the Zoysia turf was also fertilized this week with just over 1 pound of Nitrogen/1000sqft. To top the week off we cut down overgrown trees by #7 yellow tees on the River Course. Now you have a clear view of the fairway from the back tees and I think it looks so much better.
Week 14 we finished applying pre-emergent to all the cool season turf. The product that we use is a fertilizer plus pre-emergent, (13-0-5 with Dimension). Also during the week we planted more annual flowers on holes 6 and 8 on the Rock Course.
