Eleven isolates of binucleate Rhizoctinia fungi (BNR), and one isolates of each of the following species: R zeae, Trichoderma hamatum, and T. harzianum were studied in the greenhouse and field as potential biocontrol agents of root rot of snapbeans caused by R. solani. Isolates of BNR reduced disease incidence and disease severity in four greenhouse experiments. Four selected isolates of BNR and the two isolates of Trichoderma species were then screened in soils infested naturally with R. solani. Four field experiments were conducted at two different locations. Selected isolates of BNR significantly ... (P=0.05) protected bean seedlings from Rhizoctonia root rot in one or more experiments. One BNR isolate (BN-160) significantly (P=0.05) protected snapbean from Rhizoctonia root rot in all field experiments. Isolate TC.l of T. harzianum protected bean seedlings in only on field experiment. Results indicate that isolates of BNR show potential as biocontrol agents of Rhizoctonia root rot of beans. The mechanism of protection of bean seedlings from Rhizoctonia root rot by a binucleate Thizoctenia-like fungus (BNR) was investigated in laboratory and green- house studies. BNR failed to show an antagonistic interaction when grown in dual culture on agar with Rhizoctonia solani; also, filtrates from 10-day- old cultures of BNR did not inhibit R. solani. Histologic... |
