Influence of Heterodera glycines on sudden death syndrome of soybean
Studies have been carried out in Louisiana (US), on the relationships between Heterodera glycines (EPPO A1 quarantine pest) and the blue strain of Fusarium solani, the probable causal agent of sudden death syndrome of soybean, as very often the two pests are present on diseased plants. Half roots of soybean plants (Glycine max) were inoculated. Both foliar symptoms and root necrosis ratings were more severe when plants were artificially inoculated with the two pathogens on one root half than on opposite root halves.
