Multiple pest complexes on soybean: influences of threecornered alfalfa hopper injury on pod and stem blight and stem anthracnose diseases and seed vigour



Multiple pest complexes on soybean: influences of threecornered alfalfa hopper injury on pod and stem blight and stem anthracnose diseases and seed vigour



Crop Protection 6(5): 320-325



Girdles on soybean, Glycine max (L.) Merr., stems caused by the threecornered alfalfa hopper (TCAH), Spissistilus festinus (Say), were examined with regard to their effects on Phomopsis sojae Leh. and Colletotrichum truncatum (Schw.) Andrus and Moore, causal fungi for pod and stem blight and stem anthracnose, respectively. Presence of basal stem girdles had no effect on disease incidence for either pathogen. Effects of girdles were most evident on disease severity. C. truncatum disease severity ratings were significantly greater on girdled than on non-girdled stems of cvs Hartz 5171 (group V) and Bragg (group VII). C. truncatum was not observed on stems of cv. Centennial (group VI). Ratings for P. sojae were significantly greater on girdled than on non-girdled stems only for cv. Centennial, in the absence of C. truncatum. Production of diseased plant debris as a result of girdle-induced death of soybean stems occurred as much as four weeks earlier than on non-girdled stems. High TCAH populations reduced germination and vigour of soybean seeds but did not influence 100-seed weight or colonization by seedborne fungi.
