In fact it is actually stupid to be doing it in the 21st century, but it is commonplace and well entrenched in Japan and Korea. I am attacking the practice full steam in the upcoming September issue of Asian Golf Business magazine. I need any hard data and firm opinions that I can get.
Probably not much data or studies out there -- as no one is going to waste time on dumb research of stupid things! i have to change directions in Japan and Korea with these huge spray trucks and hand-wand spraying greens. Very ignorant.

Mate why are you worried about it so much? Many people still "wand" if wanding is just using a hose with a nozzle on the end. I have used a brass nozzle to apply everything from bentgrass seed (pre-soaked in water), Iron, Nitrogen, seaweed, Azoxystrobin and so on. I still use a boom spray for primo, herbicide and other goodies it just depends what you are trying to achieve. I use a brass nozzle that puts out 8-10 gallons of water per 1000 sq ft, we will use rates of iron from .75 lbs- 2 lbs of FeS04 depending on what we are trying to do. The practices utilized by "greenkeepers" back in the day are still very relevant. I have seen many greens in great condition from many different practices including "wanding" "sprayhawking" "booming" and the likes.
Ultimately we are trying to fine tune the genetic origins of the plant with minimal maintenance inputs. Those maintenance inputs can be whatever they need to be; including "wanding".
Just my thoughts of course, good luck with the article.
