Calling out tree and shrub pesticide applicators for your food gardens
For any of you who care about pesticide exposure in your vegetable gardens in the USA, I just wanted to share my experience with tree and shrub applicators who operate in residential areas. Clearly, spraying a 20' to 40' tall trees on most properties under 3 acres is going to cause significant drift, and if you're in the unfortunate downstream zone, are at risk of fungicide and insecticide contamination into food gardens that is labeled for ornamentals only.
I have found that the salesperson for these applicator companies do not consider drift and will sell most any and all jobs, regardless if it would clearly mean spraying down the neighbor's food garden. They can operate like this because fungicides and insecticides do not cause dieoff and they can be in and out without a trace. The problem is pervasive.
When they are caught in the act, the applicator will often claim that "he just has to get the contract done", and that drift into off target areas is not his problem. He'll also even throw in a "it's a legal application". Do not let them fool you, this is not ok. What I have found success in is calling the company directly and explaining that you are not ok with the drift and consider it chemical trespass. In all cases, all properly trained applicators agree that it was an invalid contract to even attempt spraying. If you do not receive a response from a local franchise, a call to corporate works as well.
Discussions with the state pesticide regulator agency indicated that this is a pervasive problem in the industry and while they make a specific push during the pesticide applicator training about cross property drift, know that most will ignore it for the almighty buck.
If anyone else has any experiences to share on how they dealt with tree and shrub applicators, I'd be interested to hear it.
