Cotton Seedling Preemergence Damping-Off Incited by Rhizopus oryzae and Pythium spp. and Its Biological Control with Trichoderma spp.
ABSTRACT Planting the cotton cv. Sure-Grow 747 in cotton seedling disease plots during the 2001 growing season resulted in high levels of preemergence damping-off among the seedlings. Four cotton pathogens, Pythium aphanidermatum, P. ultimum, an unidentified Pythium sp., and Rhizopus oryzae, were isolated from diseased seed embryos and seedlings. Disease incited by the Pythium spp. could be con...
متن کاملinvestigation on biological control of sugar beet damping-off disease by some isolates of trichoderma harizanum rafai
due to high antagonistic activity of trichoderma harizanum, 5 isolates t.h.k, t.h.bi, t.h.mo, var33 and torbat vi were selected and their efficacy was studied for controlling sugar beet damping-off caused by rhizoctonia solani, under in vitro and in vivo conditions. antagonistic ability of t. harzianum isolates was investigated as dual culture on pda in concomitant and sequential cultures, 48 ...
متن کاملAntagonistic Activities of Trichoderma spp. on Phytophthora Root Rot of Sugar Beet
Trichoderma species are among important antagonists of plant pathogenic fungi. The main purpose of this study was to evaluate the biocontrol potential of native Trichoderma spp. isolates from sugar beet fields against Phytophthora drechsleri and P. cryptogea, the causal agents of Phytophthora root rot of sugar beet. During 2007–08, 85 isolates of Trichoderma spp. from sugar beet fields in eight...
