KILLING KYLLINGA (YEAR 4)

We are now entering year 4 of our targeted attack on the Green Kyllinga in the Ryegrass collars. Our efforts the first couple of years were very effective but not completely successful. The seemingly endless rain of summer 2018 really shifted the conditions to favor the Kyllinga.  A few of the areas, although much smaller than before, have returned.  So, herbicide has once again been applied to the collars and spot treated in several areas throughout the course. The first app went out 4 weeks ago and the second this week. As before, when the weeds die back, seed and sand will be applied to the voids to grow the affected areas back in.

For those that may have missed it, below is a copy of my post from last summer about this challenging weed.

Green Kyllinga

Green Kyllinga is a relatively new problem at Chantilly. Until a few years ago we were fortunate to not have any on the property (or at least not enough to gain my attention). The Kyllinga is aggressively encroaching on several of the greens and fairways but is the most severe on the collars. Chemical controls have been in use since late spring, you may have noticed the bare and thin areas on many of the collars, these are the areas were the Kyllinga was treated.  

The plan has been to treat the Kyllinga with an herbicide and seed the bare ground. So far is has been relatively successful but Kyllinga is a very pernicious weed and does often return after treatment necessitating subsequent herbicide applications.

We will continue throughout the summer and fall months to treat and retreat this invasive species and continue seeding until the Kyllinga is a memory.

The image below shows the untreated Kyllinga.  

This image shows a collar after the Kyllinga has been treated and the voids filled with a sand/seed mixture.

The final image show the weed re-emerging after treatment through the sand and seed mix.  This is the reason repeat herbicide applications are required.
