limits on pesticides
I have a (I think) simple question: most of the fruit tree sprays I have seen and used have something in the instructions saying not to exceed some number of sprays per season (bonide says 3). Is that because it might harm the tree or is it to protect human health? I strongly suspect the latter, but I wanted to be sure. I confess that I've sprayed my trees more than the limits call for (not by much). I have a few trees that seem to be struggling, and I just wanted to be sure it isn't because of my spraying them too much. In terms of my own exposure, please understand that my trees are all small and I'll only get a small amount of fruit this whole year. I also will be eating it myself (no kids) and I am cutting back already. I know it is a poison and I should and will be more careful. I'd still be interested in any thoughts about the health dangers of spraying too much (say, every 10-14 days) but I'd especially be interested in whether that might affect tree health. thanks.
