Invasive plants: The Bane of Agriculture!

Barberry in an invasive plant that also serves as a host for the fungal disease stem rust, which attacks wheat.The above poster was used in the early 20th century by the US government to encourage citizens across the nation to destroy barberry in an effort to totally eradicate the plant and its negative effects on agriculture. They even had a National Rust Busters Club for children which awarded medals to eager little invasive pullers!
Our lab is starting a similar citizen science program this year, Buckthorn Watch, to deal with another invasive plant, common buckthorn. Buckthorn serves as an overwintering host for the invasive soybean aphid, which has had devastating effects on soybean fields throughout the Midwest. The aphid in turn is the main food source for the invasive multicolored asian lady beetle, which terrorizes your home every year. Look for more info on Buckthorn Watch in the coming months and you too can help us put an end to this invasive tyranny!
