The soybean cyst nematode, an invasive parasite that attacks soybean roots – causes over $1 billion of damage each year in the U.S. Harnessing beneficial fungi that target these nematodes could be a solution. Scientists with the Agricultural Research Service (ARS) are stepping up their efforts to control agricultural pests, without the use of chemical pesticides. One promising solution are fungi carried by the pests themselves in a symbiotic relationship.
