I sprayed a complex a couple weeks ago, using GL pathfinder with spray bar with low drift .25 nozzles. I sprayed speedzone at 1.1 oz per 1000, which is minimum rate. The weather was 82 degrees and no wind over 5 mph that day. Got a call from the pesticide inspectator about a possible issue. Somehow me spraying evaporated and translocated to the leaves on a 25foot birch and the leaves are burning or something. Is this possible. The pest inspector says that the heat could have caused the fumes to burn the leaves. Now I have to go in front of the board and throw my self on their mercy. Maybe even get a warning. I have been spraying for 15+ years and have never had a complaint or anything. Anyone else burn leaves on trees using minimum rate and no wind in 82 degree weather. For those who are curious speedzone in safe up to 90 the label says. Any advice will be helpful. I may be responsible and if I am I wanna know what to look for in the future. Thanks in advance

I get more nervous on calm cool days. It can cause a temp inversion and the volatilzed (spelling) fumes can linger right in the tree canopy zone.

I have done the same thing with speedzone to some small trees just curled the leaves and burnt some edges they all survived. I seen a photo from a big CO that one of there applicator kill a 25 ft poplar tree they said there were lot of weeds under the tree and he over sprayed. And this was a organic CO ?
I am hoping this is what happened. I just simply made my passes like normal. What's weird is this was the only tree or shrub in the whole complex like this. I sprayed over 1.5 acres in this complex and it is highly developed and a little overly landscaped but nonetheless the woman who complained is still at Woodstock mentally. Sometimes you can catch a contact buzz from the smoke pouring out of her porch. She hates anything chemical. She *****es ever time it put out fertilizer too and it's granular. She says that the granular will kill her dog. Weird woman
Ditto with Turf & Charles.
Chamber -- you did everything correctly. Too bad you will have to waste your time during the busiest time of the year going in front of "the BOARD". There is no way they can find fault with you as you applied properly.
2 things I can't stand.....Deadbeats & excess government. just sayin'

Never spray ester when it is still and hot. My no go is over 80 and 5 MPH or less. High humidity also causes more of the ester to boil off of the lawn and become vapor. There are days that I park the spray truck because it dead still and almost 90. Although I have had more days where spray drift is the prominent hazard. Not even Air Inducted tips work in 30 MPH winds.
Burned the leaves--what does that mean? Its not herbicide--unless there are herbicide symptoms--that is--officially--for phenoxy herbicides--puckering, twisting and curling, and "bowstring effect".
Also, you cannot reasonably argue that it is due to drift, volatility or over application if only one tree is affected. Also, injury should not be uniform, but rather more severe on the windy side of the tree. Was it a cold winter? Could be winter damage. It could be a root rot issue. Poor drainage can happen. Canker diseases can happen. Leaf miners can kill leaves.

Also--sometimes the homeowner will apply something to the bark mulch around the base of the tree to keep out weeds--something like Ortho Triox with pramitol soil sterilant. Sometimes Preen at ten times too much.
Clearly the "pesticide inspector" doesn't have a degree or much background in tree diseases or he would have asked such questions. You need a tree service company manager to look at it. Someone with a degree or 5 to 10 years experience, certified or licensed arborist.

I understand this but you know how these know it all bureaucrats are. Can't argue with them. I appreciate all the replys and help.
