njdep pesticide control notification program states that a notification sign (flag) be posted at property's entrance before a pesticide application. we all know that. right? got a call from a cemetery today,they are interested in controlling sandburr. few years ago there i seen a company applicating the property and they placed a 4'x4' sign at the entrance of the property that said pesticide application and the date.. i called the nj dep today and waiting for a call back. my question is -----will a pesticide application flag at the entrance be enough?
