2 temp greens in play still a bone in greens 2 & 15.
G Bruen
The damage is caused when the ground temp rises and the snow then acts like a incubator keeping the heat on the surface and the fungal pathogen starts to spread, but when its under frozen snow we are unable to apply the fungicide to stop it in it tracks.
The larger scars will either be plugged out to the side of the greens or seeded out with bent grass seed in the spring.
At the start of 2010 we trialled new products on the market with good results to give us some early recovery and growth which we will be looking at again this year.
These out breaks used to be very common in the Scandinavian countries were snow can be on the ground for 4-5 months at a time but unlike us they are not allowed to spray any chemicals as they are band.
So they have had to adopt a more traditional greenkeeping principle which I follow at Williamwood of managing the fine grasses and trying to get the biology right to maintain a healthy plant which will ultimately be less susceptible to these disease outbreaks.
And the proof of this is in the greens that were hit the worse they are all sand based greens which are great draining greens but the root zone they are built on is made up practically of a sterile material which has no biology in it to protect the plant from these disease outbreaks.
We have been addressing this issue by over seeding with bents grass seed using organic materials in our fertiliser and brewing our own compost teas to supplement the beneficial bacteria in the ground.
Ultimately what we need now is a early spring to promote some recovery and to remember that the greens always recover from what ever is thrown at them.
