The Crabgrass Report…
I have received a number of comments pertaining to the infestation of Crabgrass, particularly on tees. We have a great weed spray program in place at Burlington, which includes spring & fall applications with hand picking weeds throughout the season.
Crabgrass is difficult to control through the summer once established but is an annual weed which dies every fall. One particular herbicide has been sprayed in our rough bluegrass areas to kill crabgrass. However, this same product is toxic to bentgrass which populated most of our tees & fairways. Our main control method for crabgrass is a spring pre-emergent herbicides which stops the plant from re-germinating. The cycle of this product is every 3 to 4 year, which we are certainly due!
Options for the heavily infested tees have been discussed. (#9, 16 & 12 red).
Here are the comments.
- Hand picking these areas will make the tees look worse with large bare patches of soil.
- Re-sodding the tees will eliminate the problem but the sod will take 4 to 6 weeks to knit.
Hence, we will not be back on these tees until late season, November.
- Continue hand picking & living with some for the remainder of the season.
Knowing it will be treated in the spring.
After much discussion, we will continue to hand pick crabgrass. In larger areas more grooming & cutting will help keep the crabgrass down and giving the tee a better appearance. This will keep the tees open for the remainder of the season. Also knowing it will be treated in the spring & not coming back next year.
