This morning we are making our routine fairway spray which consists of fertilizer, a growth regulator and two fungicides. The high humidity and afternoon rain storms have increased disease pressure on all of our playing surfaces. Therefore, a spray interval of 21 days in now down to 10-14 days. It is imperative we stay on top of diseases like dollar spot before they take hold. Otherwise, the interval will be even shorter, requiring higher curative rates of fungicides. Chemicals, particularly fungicides, account for 10% of the maintenance budget. This is higher than most every other golf course. Growing bentgrass in a temperate rain forest is no simple task without the help of fungicides.
