TREE THREAT: An emerald ash borer beetle rests on an ash tree leaf. The emerald ash borer is responsible for the destruction of tens of millions of ash trees in 30 states. Native to Asia, it likely arrived in the U.S. hidden in wood packing materials. Females lay eggs in bark crevices on ash trees and larvae feed underneath the bark of ash trees to emerge as adults in one to two years.
Each year, $40 billion in field crops, trees, commercial flowers and natural resources around the world are lost to invasive pest and diseases.
“The stakes are high, and we need everyone to do their part to protect plant health,” said Greg Ibach, USDA undersecretary for marketing and regulatory programs, in a statement marking April as Invasive Plant Pest and Disease Awareness Month.
Key to protecting crops and other resources is being able to identify threats. Click through the slideshow to get a look at the top invasive pest and plant disease threats facing U.S. farmers.
