Caption

Biological pest control. Petri dishes containing different growth stages of the fungus Verticillium lecannii. Pellets of this fungus are being tested for their suitability in attacking nematode cysts which develop on soybean plant roots. The soybean plant, Glycine max, is one of the world's most important sources of vegetable oil and protein. Six species of nematode worms attack the soybean root, with one species of Heterodera nematode causing root cysts. Fungal bio-control of the Heterodera nematode involves introducing this fungus into the soil as a natural means of protecting the soybean roots from infection.
