Blame Isaac Newton: Applying fungicides with no present disease can boost levels of other pests

摘要

For a moment, flash back to your high school physics class and Newton's third law of motion. You were paying attention, weren't you? Well, here's a refresher: For every action, there is an equal and opposite reaction. In a sense, it mimics what fungicides do in corn and soybeans. When all factors of the disease triangle converge - pathogen, environment, and host - fungicides preserve yield by foiling fungal diseases.
