I have done a lot more than just read up on it. It works, it just smells terrible. There are a lot of things we use as growers that don't smell good that work well. This is just another item to add to the list. In all actuality, people tend to stray away from the milk just for the smell issues with it. WE have progressed as growers over the years and have found more effective ways to rid ourselves of PM. Milk, like most remedies only works for a limited amount of time. To really get to the source and stop it, you need sulfur vapor. There is no way around it. It doesn't harm the plants and is a final solution. WE may not have been using it for 50 years, but it works like nothing else (and kills parasites). My advice to you, try something before you suggest somebody uses it. Otherwise, you just come off as a troll that is lacking experience but well stocked up on assumption.
