“…These differences may be explained by the e ciency of bio lm formation on the target crop by the bacteria constituting each biopesticide. The bacteria that are the main agents in each biopesticide, MP, VK, and BK, have been isolated from Lactuca sativa, L. sativa, and Brassica rapa, respectively (Maeda et al, 2014;Ogiso and Shimizu, 2000;Takahara et al, 1993). It is conceivable that there are differences in the colonization mechanisms of broccoli by these bacteria.…”

Meta-analysis was performed to evaluate the effects of biopesticides on broccoli head rot. Three registered biopesticides, Masterpiece, Vegekeeper, and Biokeeper, were effective in preventing disease as compared to the untreated control but were less effective under conditions of high disease frequency. Masterpiece was more effective in control when the frequency of application was increased rather than the concentration. However, Vegekeeper, and Biokeeper were more effectively controlled by treatments with higher concentration ratios. In the rainfall experiment, Masterpiece and Vegekeeper were more effective than Biokeeper.

“…However, BK treatment had better disease protection effect in the absence of rainfall. BK is a nonpathogenic Erwinia carotovora, generated by applying a mutagen, ethyl methanesulfonate (EMS), and it is possible that these mutations reduce its ability to form bio lms (Takahara et al, 1993).…”

Two pathogenic strains of E. carotouora subsp. carotouora 2T-2 and TT-4 with high bacteriocin activity but low sensitivity to the bacteriocins of other strains were treated with ethyl methane sulphonate (EMS). Two avirulent mutants A-f-39 and B-e-19 developed from 2T-2 and TT-4, respectively, by this treatment had the same bacteriocin activity as their respective parents and inhibited the in uitro growth of pathogenic strains of this species. The disease control of these two mutant strains were compared in the field in 1995 and 1997 t o the control by CGE234M403 (M403) (a commercialized biocontrol agent), a mixture of A-f-39 and M403, and an agrochemical (basic dithianon-copper chloride). The protection obtained with A-f-39 was comparable to M403 and was better than that with the chemical. The mixture of A-f-39 and M403 consistently gave the best results in all the field trials.
