Beijing is very hot in July -- temperatures are regularly higher than 90⁰ F every day (the warmest day so far was 107⁰ F). We're also having regular thunderstorms.
The combination of high temperatures and wet soil are perfect conditions for disease to develop. The modular field is made up of Kentucky bluegrass, which does great in a cool-season environment like Michigan. Beijing's hot temperatures and the low mowing height we're using puts the grass under a lot of stress, which makes it even more susceptible to disease.
We're using an integrated disease management program to keep the turf healthy. This includes fungicides and light but regular fertilization. The root zone of the turf is sand-based, which prevents the soil from holding extra water. This also helps reduce the risk of disease.
At 6 a.m. every morning I inspect the field for disease. I've also been in contact with local golf course superintendents and several Michigan State faculty members and alumni who are pathology experts to ensure that the field is in the best possible conditions for the Olympics.
