Mkay, I'm going to take a stab at this. The only experience with neonics I have seen was just a few miles up the road, last year, was when neonics where sprayed onto blooming trees, which resulted in the raining of dead bees, thousands of them. I didn't know that neonics where the pesticide that coats seeds.
I feel that this grain farmer did have some points but also feel he sounded like a politician skirting the issue. I'm not a chemical biologist... but what I can see clearly is that neonics that are coating seeds and sprayed onto trees, airborn, are going to kill bees, pollinators and... people.
I don't have the answer, I'm just tired of poisons everywhere.
