“…X. campestris pv. poae was reported to effectively control annual bluegrass (Imaizumi, Nishino, Miyabe, Fujimori, and Yamada 1997), and there was a direct dose response of bacterial concentration with annual bluegrass control (Imaizumi, Tateno, and Fujimori 1998). A commercial bioherbicidal product (Camperico † ) consisting of dried bacterial cells was developed (Nishino and Tateno 2000).…”

Several isolates of a previously unreported bacterial pathogen were discovered on common cocklebur seedlings in Chicot County, AR and Washington County, MS. Diseased plants in nature exhibited angular-shaped leaf spotting symptoms on leaf margins and central leaf areas. The isolates were cultured from diseased leaf tissue and tentatively identified as Xanthomonas spp., and their virulence on common cocklebur seedlings compared. The most virulent isolate (LVA987) was used in studies to define disease progression on cocklebur seedlings and to carry out a host range evaluation on various weeds and crop plants. High virulence was found on common cocklebur marestail (Conyza canadensis) giant ragweed (Ambrosia trifida) ] and common ragweed (Ambrosia artemisifolia). These results suggest this pathogen may be useful for the biological control of these important species of weeds. This is also highly relevant since all of these weeds have evolved resistance to one or more synthetic herbicides and are thus becoming more difficult to control with conventional herbicides.

“…The significant differences observed among replications can be explained by varying outside temperatures across the sequentially grown replications and the inability to cool the greenhouse. Growth rates and xanthan production of xanthomonads are affected by temperature and influence disease development (Imaizumi et al. , 1999).…”

Phenotypic and molecular genetic characterization indicate no major race‐specific interactions between Xanthomonas translucens pv. graminis and Lolium multiflorum

Bacterial wilt of forage grasses, caused by the pathogen Xanthomonas translucens pv. graminis (Xtg), is a major disease of forage grasses such as Italian ryegrass (Lolium multiflorum). The plant genotype-bacterial isolate interaction was analysed to elucidate the existence of race-specific responses and to assist the identification of plant disease resistance genes. In a greenhouse experiment, 62 selected plant genotypes were artificially inoculated with six different bacterial isolates. Significant differences in resistance were observed among L. multiflorum genotypes (P < 0AE001) and in virulence (intensity of disease symptoms) among Xtg isolates (P < 0AE001) using the area under the disease progress curve (AUDPC). No significant genotype-isolate interaction (P > 0AE05) could be observed using linear regression modelling. However, additive main effects and multiplicative interaction effects (AMMI) analysis revealed five genotypes which did not cluster close to the origin of the biplot, indicating specific interactions between these genotypes and some bacterial isolates. Simple sequence repeat (SSR) markers were used to identify marker-resistance associations using the same plant genotypes and bacterial isolates. The SSR marker NFA027 located on linkage group (LG) 5 was significantly associated with bacterial wilt resistance across all six bacterial isolates and explained up to 37AE4% of the total variance of AUDPC values. Neither the inoculation experiment nor the SSR analyses revealed major host genotype-pathogen isolate interactions, thus suggesting that Xtg resistance, observed so far, is effective across a broad range of different bacterial isolates and plant genotypes.

“…CAMPERICO (Xanthomonas campestris pv. poae isolate JT-P482) was registered in Japan for control of annual bluegrass (Poa annua L.) in 1997 (Imaizumi et al, 1999 The mode of action of each biocontrol agent is as varied as the microorganisms themselves (de Luna et al, 2011). They range from simple but effective compounds like cyanide (Kremer & Souissi, 2001;Owen & Zdor, 2001) and organic acids to complex molecules with tertiary structure (Bouizgarne et al, 2006;Gurusiddaiah et al, 1994), and from secondary metabolites (Kroschel & Elzein, 2004) to plant growth regulators, such as auxins and ethylene (de Luna et al, 2005).…”
