In a leafy greens trial, farmers noticed that caterpillars did not eat the treated plants compared to the untreated control, and the farmers were not told in advance which plants were treated, suggesting the pest resistance effect is real and not a farmer expectation bias.

Evidence Quote

we had a leafy greens farmer say, 'We noticed that the caterpillars didn't eat this particular one.' And we're like, 'Well, that's really curious because we didn't tell them which one was treated and which one was control.' And and we were pretty happy to know that it was the treated one.
