Herbicide Application Evaluation

 We are now 3 weeks from our first application of non-selective, herbicide to be applied on the mapped areas of Bermuda grass infestation. As I have shared in previous posts, we identified the Bermuda within our fairways by using aerial, drone photography. We conducted the drone flights this past winter when the Bermuda was fully dormant. The color differential between the Bermuda and the Bent was extremely evident which allowed us to draw GPS boundaries around the Bermuda. 

Last week, we loaded the sprayer with water and turf paint. We then printed off our maps and watched as the sprayer crossed over the boundaries within the fairway. We were very pleased with the accuracy of the maps and the mechanical functionality of the sprayer. 

This coming week, we will ratchet up the "stakes" by applying Pylex to the Bermuda areas. The Pylex, applied at .1 oz/acre will not kill the Bermuda (or we would just use that:), but it will bleach it white. By using the herbicide and the subsequent color reaction, we will then be able to visually inspect the accuracy of the drone maps and the accuracy of the sprayer itself. Should we notice overspray or misses, we will note those areas and supplement the applications with hand work. 

Once the Pylex is sprayed next week, it will take a week or so to notice the discoloration. In our next post, we will report back on the success of this second test. 

*As a continued reminder, the first herbicide application is scheduled for July 10th, 2023. From July 15th through our August closure, please expect randomized areas of dead/burnt turf scattered throughout the fairways.* 

Bermuda Grass Eradication Set to Begin in 30 Days

 Now that we are 30 days from our first herbicide application, I will send weekly reminders about our Bermuda Grass Eradication Project. 

Weather permitting, we will apply our first round of herbicides on Monday, July 10th. 

I. What to Expect: 

On or around July 15th, you will begin to notice scattered, irregular areas of burnt turf throughout the fairways and 1st cuts. The amount of affected turf will vary amongst the golf holes. For example, there will be little disruption on golf holes 1-5. Conversely, there will be noticeable, impacted areas throughout golf holes: 8,9,10,11,12 and 13. On July 10th, when we make our first herbicide application, there will be posted signs explaining the project and instructing the player to consider any "burnt area" as Optional Ground Under Repair. These areas will be sprayed again on July 31st, August 21st and September 1st. So, from about July 15th through our scheduled summer closure, beginning on August 22nd, these areas will be dead. On Labor Day, we will begin stripping and replacing all of the dead turf. 

II. When to Expect: 

1. July 15th through the Summer Closure - Scattered, dead areas of turf throughout fairways and 1st cuts 

2. September 1st through September 15th - All impacted turf will be stripped and replaced with new bent grass 

3. September 16th through September 30th - The new sod will root in. 

4. October 1st through October 31st - The golf course will look and play at nearly 100% of expectation. The only noticeable remnant of the project will be slower healing sod seams. We expect the fall golf season to be spectacular!! 

III. Why: 

This project is a tremendous investment in the betterment of Kinloch Golf Club. The Common Bermudagrass will continue to spread over time. Now is the time to reset our fairways for many years to come. 

We thank you in advance for your patience and understanding as we continue to make Kinloch better and better and better...
