I'm happy to say, I've not had to deal with any errant herbicide treatments in the 20 or so years I've been a landowner. My producer neighbors are very attentive about their pest control practices for which I am EXTREMELY grateful. I'm very protective of my trees as we have SO MANY in ND. I go so far as to include the trees in my rental contracts and make the cost per damaged tree an amount that ensures more than a passing consideration when it comes to herbicide use. I even went so far as to include a buffer zone of land around my trees that remains uncropped and in grasses. I'm pretty sure I'd be a fair bit angry to have my trees damaged or killed by careless herbicide applications and would be looking for compensation. Hate to see this happen anywhere as it's fairly disconcerting.
