Protective and curative activities of zinc thiazole against rice bacterial blight. a Lesion length (cm) of PXO99 in rice leaves treated with zinc thiazole: curative test at 7 dpi. Rice leaves were inoculated with Xoo and were sprayed with different concentrations of zinc thiazole (0, 12.5, 25, 50, 100 and 200 μg/mL) at 12 hpi. b Lesion length produced by PXO99 in rice leaves treated with zinc thiazole: protective test at 7 dpi. Rice leaves were sprayed with different concentrations of zinc thiazole (0, 12.5, 25, 50, 100 and 200 μg/mL) and were inoculated with Xoo after 12 h. c Symptom development of Xoo-inoculated leaves in the zinc thiazole curative test at 7 dpi. d Symptom development of Xoo-inoculated leaves in the zinc thiazole protective test at 7 dpi. Bar = 1 cm. Xoo-inoculated leaves were used as a positive control, and leaves treated with water (containing 0.1% DMSO) were used as a negative control. Error bars represent standard errors from three independent replicates. *: P < 0.05; **: P < 0.01; ****: P < 0.0001
