As directed by the DNR no less. How do you communicate this to insects, reptiles, amphibians and BIRDS! And where is the science that ensures that the time frame between toxic and safe is correct? After 3:30 pm today? Seems arbitrary to say the least.
There are indeed noxious invasive plants in the spray area as seen in the photograph behind the sign but mowing early and before plants flower is a much less toxic way to stop them in so much as I wonder when this area was previously sprayed. Would lay money on the fact that it has been poisoned before...
Once the poisoning becomes evident it also becomes very ugly to look at...pesticide treatment lasts and degrades the visual beauty of landscape for a long time.
ps I reread what I wrote earlier and do apologize for the spelling errors...embarrassing. Guess I was a bit riled up.
