Compound from Wild Tomatoes is Natural, Effective Herbicide

A naturally occurring compound derived from wild tomato plants is also a fast-acting, nontoxic herbicide, according to researchers at North Carolina State University.

NC State entomologist Dr. Mike Roe had previously worked with the compound – known as 2-undecanone – as a natural replacement for the chemical DEET in insect repellents. Both he and his NC State colleague, entomologist Dr. George Kennedy, were exploring whether 2-undecanone could be used as an insecticide on plants, when they noticed an unexpected side effect: it killed the plants.

*Growth of cropland, loss of natural habitat to blame*

The continued growth of cropland and loss of natural habitat have increasingly simplified agricultural landscapes in the Midwest.

In a study supported in part by the National Science Foundation’s (NSF) Kellogg Biological Station Long-Term Ecological Research (LTER) site in Michigan–one of 26 such NSF LTER sites around the world–scientists concluded that this simplification is associated with increased crop pest abundance and insecticide use.
