Plenty of guys are out spreading fertilizer, have been for about 2 weeks.
I agree the law does not make sense when it only considers the calendar and not GDD or soil temps.
That said, assuming the signs mean fertilizer could be flawed. albeit unlikely...as most guys dont know how to adjust a program to do an application without the fert....
This law seems to be like most others, a pat on the back for the politicians and kudos from the environmentalists, but no means of enforcement. I think that enforcing the pesticide license takes precedence over the fertilizer dates, but they cant/wont/dont do that so do you really expect them to go after the fertilizer?
bartjr, how do you know your lawn is take over with crabgrass? we are still well within the window of prevention, and those of us with licenses have products in our tool box that open that window even further, especially us pros that can spray liquid pre-emergence that will give post emergent control as well.....good luck with the lawn
That is kind of what I thought,,, but because people don't differentiate between fert and pre-m,,, it difficult to figure out what anybody is really talking about...... To answer your question, pesticides are regulated for commercial use and fertilizers now have their use restricted by date for all.
