biostudies-literatureUnknown11(4)Chowdhury RNPhytophthora sojae and soybean cyst nematode (SCN) are important pathogens of soybean. Although these pathogens infect soybean roots, there is limited evidence of any interaction between them. The objective of this study was to examine the interaction between SCN and P. sojae on soybean in the greenhouse. Seeds of four soybean cultivars (Jack, Surge, Williams 82, Williams) were pre-germinated and placed in cone-tainers (Stuewe and Sons Inc., Tangent, OR, USA), containing a steam pasteurized sand-clay mixture. The experiment was set up in a completely randomized design with five replications and performed twice. Two P. sojae isolates were used in this study that represented two different virulence pathotypes (simple and complex pathotypes). For each isolate, soybean plants were not inoculatPlants (Basel, Switzerland)560https://www.ebi.ac.uk/biostudies/studies/S-EPMC8880169biostudies-literatureExamining the Interaction between Phytophthora sojae and Soybean Cyst Nematode on Soybean (Glycine max).PMC8880169Chowdhury RNByamukama EOkello PNfalseExamining the Interaction between Phytophthora sojae and Soybean Cyst Nematode on Soybean (Glycine max).Phytophthora sojae and soybean cyst nematode (SCN) are important pathogens of soybean.
