Phytosanitary measures to control diseases require sensitive and reliable detection methods. In case of Erwinia amylovora, the causal agent of fire blight, there are several methods developed.

Real-time PCRs (both with SYBR Green and TaqMan probe) and LAMP were most sensitive and allowed to detect E. amylovora even in the samples where the concentration of cells was lower than 2 x 101 cfu/reaction. The highest repeatability was obtained using conventional method and Real-time PCRs. Of the methods used, only the LAMP technique was very insensitive to plant impurities.
