Yah, it's gotten overboard. What I find humorous is that Bruce Ames (previous chair of biochem at Berkeley) proved that organic produce is higher in carcinogens than conventional back in the 80's.
Life is full of pendulum swings. In the 40's, 50's and 60's the general public was enamored with lab created foods, pesticides, etc, the mindset being that technology could improve on nature. All sorts of nutty pesticides were used back then, with reckless abandon. (My step-father grew up on a farm during this time period and ended up coming down with cancer in his 60's.)
Then, in the 60's and 70's a small group of folks began pushing against the pesticides of the day (eg, Silent Spring), and in the 80's the organic movement started to rise. Then, somewhere in the 2000's I guess, organic went mainstream and really took root in the millenial generation, who I think viewed it as some sort of counter-cultural ideal.
The EPA has come a long way since the 1960s, and modern pesticides (as well as worker protocols) render their use quite safe. But, the pendulum has swung very hard to the opposite extreme, where the mainstream mindset is that anything produced in a lab is harmful (and contrariwise anything originating in nature is good / beneficial).
The truth almost always lies somewhere in the middle of two extremes. However, it's human nature to polarize on extremes.
We are a country of fearful neurotics and hypochondriacs. Here's a quote from a SoCal avocado growing group I belong to:
"I've heard a few people mention white washing the bark of your tree and I don't understand why one would need to paint a tree with a chemical based paint? I want all the trees in my yard to be 100% organic. so tell me what white washing is and why it's important? Is it important? I live in Claremont California."
My response:
$%*(@#@$$, so you've run a lab analysis on such painted tissue and found levels of "chemicals" exceed EPA standards, what exactly are those chemicals? 95% of the organic/natural movement is a joke based on fear and ignorance. Having said that I have been pushing a spray of kaolin clay wettable powder not because I'm a fearful neurotic but because it's cheap and a helluva lot easier to mix and apply. https://www.groworganic.com/products/surround-25-lb...
Don't know if Captan would help but it has no REI interval posted on our Aggie vineyard pesticide list.
