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.
