Recently, research found that time of sudden death syndrome foliar symptom onset, i.e. the time when the first SDS foliar symptoms are observed, is strongly correlated with late season SDS severity and soybean yield. These results were obtained from single soybean genotypes planted in commercial and research fields, but suggest that management practices that delay disease onset should be most effective at protecting soybean yield. This projects tests if time of SDS onset can be a useful measure for early screening of soybean genotypes for resistance against SDS. It monitors SDS progress over time in soybean genotypes with varying levels of resistance and determines the correlation between resistance and time of foliar disease onset.
