There has been some correlation between soybean cyst nematode (SCN) and red crown rot (RCR), as well as infection timing and disease severity. This project evaluates the timing of infections, interactions with SCN, and efficacy of commercial products to provide farmers with best management practices.

Read below for a project update provided by Dr. Boris Camiletti.

“Experiments have begun in the greenhouse to refine protocols for evaluating commercial products against RCR and its interaction with SCN. Working with nematodes required a change in substrate and corresponding adjustments to the protocols. Variability observed in past trials further underscored the need for this preliminary testing.

The second round of preliminary tests is expected to begin soon. Additionally, greenhouse experiments will assess the effect of host age on disease development and examine the interaction between RCR and SCN.”
