I think a lot of folks here grow their own fruits and vegetables, I grow and sell fruit myself, and I thought it might be of interest what some people will do. A guy not too far from here must have had problems growing apples because blights are a serious problem here (mostly Cedar rust and black rot) so he apparently attempted to solve the problem by using a stronger pesticide mix. According to what was said he used a commonly sold home use orchard spray but mixed it at least TEN times the plainly stated mixing rate, Some said it was more like twenty times the rate! He then proceeded to climb up into the tree with only a terry cloth "mask" over his nose and mouth and started spraying, by the time he finished he was soaked with spray (as one might imagine in such a scenario). He was complaining of his skin burning and feeling dizzy so his family took him to the ER where he died a short time later from swelling in his throat.
This is NOT a warning about dangers of this spray, it is safe when used as intended and has been sold for many years. I am not certain as to the exact brand but was told it a common consumer rated home orchard spray that was bought at either the local farmers Co-Op or Tractor Supply, they both sell the same brand. My point is NOT that the spray is dangerous but rather it's about what some people will do! In this case the guy was definitely a good candidate for the Darwin award and was the ultimate cause of his own demise. These pesticides are safe when used correctly, just use common sense.
