Common bacterial blight (CBB), caused by Xanthomonas axonopodis pv. phaseoli var.
fuscans (Xapf), negatively impact common bean production globally. Considering the
potential of phosphites to protect plants against different diseases, this study investigated the potential of using manganese (Mn) and zinc (Zn) phosphites in common
bean for CBB control. Plants were inoculated with Xapf 48 hr after being sprayed
with water (control) and solutions (7.5 ml/L) of Mn and Zn phosphites. The area under
common bacterial blight progress curve (AUCBBPC) was significantly lower by 34%
and 59% for Mn and Zn phosphite treatments in comparison with the control treatment. The AUCBBPC was significantly reduced by 38% for Zn phosphite-sprayed
plants compared to Mn phosphite treatment. Phosphite-sprayed plants displayed
higher values for area under the curves of net CO2 assimilation rate, stomatal conductance to water vapour, transpiration rate and internal-to-ambient CO2 concentration ratio than non-sprayed plants. This indicates the effect of Mn and Zn phosphites
in attenuating the photochemical dysfunctions caused by Xapf infection. Moreover,
plants sprayed with Mn phosphite displayed higher values for area under the curves
of efficiency in capturing the excitation energy of open reaction centres of PSII and
electron transport rate than those non-sprayed indicating their capacity to preserve
the capture and the use of the collected energy more efficiently. Lower AUCBBPC
for Zn phosphite-sprayed plants resulted in higher concentrations of total chlorophylls. The Zn phosphite-sprayed plants showed higher values for area under the
curves of β-1,3-glucanase, phenylalanine ammonia-lyase, polyphenoloxidase, ascorbate peroxidase and superoxide dismutase activities. The Zn phosphite spray primed
the plants to enhance their defence response and antioxidant capacity to reduce
Xapf-triggered oxidative stress with the preservation of the photosynthetic apparatus more efficiently. MenosCommon bacterial blight (CBB), caused by Xanthomonas axonopodis pv. phaseoli var.
