Moss control on creeping bentgrass greens has become an important topic in recent years as mowing heights have decreased. Superintendents in the Chicago area have been using standard baking soda as a selective control.

The following pictures are from Tim Christians, Supt. of Makray golf course. He is using 6 oz of baking soda per gallon of water and spot treating moss as it appears. He is getting good control in about 24 hours following application, with no damage to the bent. As is the case with any moss control, reapplications will likely be necessary.

I would recommend limited experiments with spot treating before adopting this practice, but it seems to be working and it is very inexpensive.

Before treatment:

24 hours after treatment with Baking Soda.

Very interesting. Is this solution being sprayed on the entire area or carefully applied to the moss only. We have some moss on some areas of greens. Ferrous Sulfate has began to take it out but if I could get these results with baking soda I believe the ferrous would keep it from returning.

Any thoughts?

We spot spray with the baking soda. We have it in only small areas on a few greens and this has been doing a good job of taking it out.
