EARTH.COM - Did you know that plants, just like humans, can fall ill, too? And much like our world, theirs is not immune to disease outbreaks and pandemics. As nature-lovers and responsible stewards of the earth, it’s vital we understand how we are unintentionally facilitating the spread of pathogens that cause “plant pandemics.”
Two recent studies from UC Riverside have revealed that native plants and non-native crops don’t play well when they’re neighbors. Both being attractive hangouts for pests, they’re unwittingly spreading diseases to each other.
Pathogen and plant health
“We have changed the landscape, and it’s created opportunities for pathogens to thrive,” said UCR entomologist Kerry Mauck, who co-authored the studies. “We have introduced pathogens that damage native plants, and on the other side of the coin we have endemic pathogens that mutate to infect crops.”
