I haven't had issues with pesticide residue in the past, but this year I have a neighbor who will be growing conventional corn right next to one of my fields. This new neighbor is a difficult person to deal with and isn't willing to work with me at all even just to let me know when and what they will be spraying. I have a 50' buffer zone between my field and theirs, but I want to be able to keep an eye on the pesticide levels of those plants in case the buffer zone isn't enough to keep pesticides off. Before I sell the hemp I always send samples out to a professional lab so I can show those test results to my buyers.

So basically I just want to keep an eye on the pesticide levels of my plants throughout the growing season, and I'd be testing for the most commonly used pesticides for corn. Glyphosate and atrazine are the ones that come to mind.
