Microbial inoculation and As treatment modulates blast infection in rice plants. Rice cultivar Seraceltik was germinated on water and transferred to 8-L system containing rice nutrient solution. After 21 days the plants were treated with natural isolates EA105 or EA106 with or without (5 μM) As(III) and incubated for 7 days. Two leaves per plants were used for M. oryzae 70-15 cut leaf assay. (A) Representative images for M. oryzae 70-15 infection after 5 days post-treatment (Scale bar = 10 mm). (B) Degree of M. oryzae 70-15 infection measured by lesion size measured by length and width. Each treatment had five plates and repeated twice with similar results. Error bars indicate standard error. Different letters indicate statistically significant differences between treatments (Tukey's HSD).
