One of the main reasons behind 13 green being consistently stressed out season to season is the microenvironment that encompasses it. First being shade tolerance, already a small green at just over 6,500ft2 it needs all the exposure it could get. The green faces east to west, therefore the sun rises and sets along the left side of the hole overtop of the slopes. Although with 3 Pine trees on the left slopes this blocks of much of those rays, especially in the shoulder seasons when the suns path is lower and lower on the horizon. We would often use an app called Sun seeker, where you could see how much shade a specific area that you were monitoring would get depending on the time of year and available sunlight.

Another argument for air flow and circulation through this green could be an issue. This because the surrounds are all heavy sloped, with the green cut through the middle.

Compared to the other usual fungicide applications that all other green surfaces get this green had a few extra. This because we had to get control of the Pythium that was in the soil profile and once found out, was at a injury threshold state. One of these specific applications was a Segway/Disarm mix that when we were first treating the disease was applied every 10 days. The output amount for this spray was at a 2oz rate to ensure better coverage overall. Segway was mixed in at a 25ml/100m2 rate and the Disarm was at 11.5ml/100m2.

The fungicide segway's active ingredient is cyazofamid used to act against the Oomycete fungi. And although it has little systemic activity it is utilized more as a protectant against any further spread and formation of the disease pathogen.

Disarm's active ingredient is fluoxastrobin acting as a broad-spectrum fungicide for the control of diseases, in our case Pythium . It works by interfering with respiration in plant- pathogenic fungi, and is a potent inhibitor of spore germination and mycelial growth overall.

One application that we did later in the heat of the summer that really showed the most progress and regeneration of healthy turf grass following the application was a Exteris app. Now this spray was based of new information from a soil sample that we sent out to Guelph. It returned with findings of nematodes being present at alarming rates in the soil sample from 13 Green. After doing some research, a list of possible fungicide applications became smaller and smaller as nematodes are generally not known to be an issue in Alberta, and so not many products on the market were advertised for there control. We ended up going with Exteris at a high rate of 500ml/1000ft2 because its active ingredient fluopyram is contained in this product as well as other approved nematicides.
