SCN-Resistant Soybean Varieties

There are hundreds of SCN-resistant soybean varieties available to Iowa soybean farmers. These varieties vary greatly in their agronomic productivity as well as their ability to control the soybean cyst nematode (SCN).  The largest project in the Tylka research laboratory annually evaluates SCN-resistant varieties for yield and effects on SCN population densities. This work is funded by the soybean checkoff through a grant from the Iowa Soybean Association. Read more about SCN-Resistant Soybean Varieties

Interactions of SCN with other pests and pathogens

The soybean cyst nematode (SCN) is very damaging in its own right. But it also affects and is affected by other soybean pathogens and pests.  Work in the Tylka research laboratory has studied the effects of SCN on infection of soybeans by the soil-borne fungi Phialophora gregata (causal agent of brown stem rot) and Fusarium virguliforme (causal agent of sudden death syndrome). This work has been done in collaboration with personnel in the laboratories of Dr. Charlotte Bronson (retired) and Dr. Read more about Interactions of SCN with other pests and pathogens
