Evaluation of an indigenous isolate of Phoma herbarum (SYAU-06) for use as a mycoherbicide against Commelina communis
Plant pathogenic fungi isolated from Commelina leaves collected from Benxi area is identified as Phoma herbarum through morphological and molecular method.Under the same inoculum concentration, the infection ability of mycelium on Commelina was the strongest, followed by conidia.Chlamydospore was the weakest.For successfully controlling Commelina by Phoma herbarum SYAU-06 strain, the mycelium inoculum concentration should be more than 107 mf · ml-1, incubation time between 7~9d, and host plant before 3 leaf stage.Host range tests showed that only the leaves of maize and sorghum were slightly injured among 18 crops in 7 families.Within the tested 27 species of weeds in 14 families, dayflower was high sensitive, amaranth and pigweed slight sensitive.According to the virulence and security, Phoma herbarum SYAU-06 strain is potential mvcoherbicide.
