So I need your guys thoughts on a issue that has come up on a piece of rented land of ours. About 10 days ago we sprayed our wheat with just Curtail M. It was a breezy day from the east but was only windy above about 4 feet and we were using a trailing boom pt. sprayer. Anyways along this field is the landlords driveway to his home which has willow and spruce trees up both sides. As it was windy that day dad stayed away from the trees 10 to 12 feet just to be safe. But now the willows are showing some kind of damage on the lower branches and needless to say it is not a good situation. What is really interesting is that because dad stay away from the tree line their is absolutely no weed kill for those first 10 to 12 feet into the field. I am certain that we will be paying something out of pocket for this as i don't think we are covered under our farm policy for something like this (I will check that on Monday). So my question is, what is a 15 to 20 foot tall 15 to 20 year old willow tree worth, taking into account clean up and replanting and such. Also have any of you ever gone through something like this with trees before, if so do you have any advice? Thanks in advance
