What
are the current strategies for management of ASR?
Resistant
Varieties:
All commercial soybean varieties currently available are susceptible
to ASR. Current research includes screening germplasm for resistance,
and resistant varieties are expected to be a successful long-term
solution for ASR. Resistant commercial soybean varieties are still
several years away.
Foliar
Fungicides: Proper
application of an appropriate fungicide has been shown to effectively
manage ASR. Early detection of the disease is required for the most
effective management. Fungicide applications may reduce yield losses,
depending on the plant developmental stage, time when ASR is first
detected, and fungicide application method. Several
fungicides are registered in the United States for use on soybeans,
and Section 18
fungicides are currently being activated at the state level.
