What is it About This Soil That Protects Plants From Devastating Disease?

Plants around the world are constantly under attack — often with big implications for humans. In the 1960s, millions of elm trees in Britain, France and the U.S. fell victim to Dutch elm disease, which clogs the vessels that carry life-giving water to the trees’ leaves. Starting in the late 1980s, Brazil’s thriving chocolate industry crumbled when witches’ broom disease devastated its cacao trees. Lately, banana growers have become increasingly concerned about Panama disease, which is spreading rapidly and threatening to wipe out their crops. The attackers, like many of the infectious agents that harm humans, are tiny but devastating fungi, bacteria and other microbial parasites.
