So many important points! And thanks for linking my article. It breaks my heart to think about the wanton and deliberate destruction of the chestnuts, and so many other trees, which is then blamed on an insect or a fungus. The destruction of livelihood and food sources has been going on right under our noses for more than a century! This is another so-significant reason why we need to drop the belief in disease of ANY living thing being caused by an outside "invader" be it a virus, a fungus, a mold, a parasite, or an insect.

There was a beautiful bur oak tree next to my house that died suddenly one spring about 20 years ago. The arborist who took it down said it was around 150 years old, so it was there before my house and before any other settlement in the area. When this was oak savannah on the Mississippi River bluffs, traversed and probably nomadically settled by Dakota people but otherwise wild. He said it was oak wilt. I believed it then, not now.

My last comment: I think what the insects tell us about our gardens, at least most of them, including mine, is that the soil we grow food plants in is unhealthy to one degree or another. I got a refractometer, probably the same one you mention, but couldn't calibrate it properly so I didn't get actual readings on my plants. I'll try again. But the presence of insects as the plants grow is the sign that all is not well. I follow Nigel Palmer on Substack--https://www.youtube.com/@nigelpalmer3439. He posts rarely, but it's almost always about how to make various preparations from plants or eggshells and vinegar, or local indigenous materials, to build the soil and strengthen the plants. He has one video on how to use a refractometer. I suspect the soil is unhealthy due to aerial spraying, but also to our not knowing how to identify what it needs and supply it regeneratively, even those of us who are 100% committed to not using any chemical pesticides or soil builders.

Thanks for the thorough exploration! I appreciate your perspective very much.

Thank you for this well researched article. Fascinating and in line with what I know about germ vs terrain theory.

I work on a small organic vegetable farm. The couple that owns it cares very much about the soil health and producing nutrient dense veggies. They never till, use compost, reject chemicals that are allowed by USDA organic standards but they feel are harmful, they are always checking the microbial life and doing soil tests. Yet, they still deal with some aphids, other insect pests, and mold/fungal issues. I had never considered the UV light being blocked by the greenhouse and hoop houses we use during the New England winter as a possible culprit. But we still have these problems when growing outside in direct sun. I often read about how healthy plants don't have these problems, but I have not been able to find anyone that produces fruits and vegetables in any large quantity that doesn't have these problems or has natural a solution for them.

I am going to inquire about the Brix test and see if I can find any correlation to our crops that have issues. Thanks again!
