Abstract

The authors studied different soybean leaf and stem diseases for 11 soybean varieties in different maturity group. The tests were analyzed in untreated large-plot of fungicides in four geographically locations. The infection rates were determined in leaf infection caused by Peronospora manshurica, Septoria glycines, and Cercospora kikuchii. In the case of the soybean stem pathogens Phomopsis phaseoli, Colletotrichum glycines, Sclerotinia sclerotiorum and Macrophomina phaseolina are also provided on the differences in infection between the varieties. In their studies, they determined the dominance conditions of the most important soybean diseases in different microecological characteristics of this vintage, providing preliminary information to the seed production and breeding.
