I haven't been to Denmark myself to see what the conditions actually are, but I have spoken face to face with supers working there, and I am reliably informed that pesticides are used on golf courses, albeit sureptitiously.
Here in France, certain pesticides have been phased out. For example, there is at present no reliable insecticide labelled for turf since carbaryl was banned for turf use. On the other hand, other products have recently come onto the market. Heritage fungicide is one that has been labelled for turf in the past two years. Rumor has it that we'll soon have carfentrazone (aka Quicksilver) for moss control. There is a ten year plan to phase out certain other products, but there is no talk of a total pesticide ban for golf courses in the immediate future, at least not in France, and not Europe-wide.
These and thousands more pesticides are available for other agricultural applications, including landscapes and ornamental flowers.
And Tom, strictly speaking, crows are a biological grub control.
