Today I had the pleasure of talking with a man in his late 80's who had been a farmer in Florida for the first half of his life. As a teenager he began spraying the family farm with DDT. No safety precautions. No suits, no respirators, no eye protection. At the end of an entire day of spraying, his grandmother opened a can of milk and washed out his eyes with that. He said DDT just gunks up when you try to wash it out with water.
A couple thoughts...
The good old days aren't always the good old days.
Some crops really aren't suited for south Florida.
These are the good old days... we have so much more knowledge and so many more options than we did years ago.
