Resumo: The effect of different levels of nitrogen fertilisation on the susceptibility to peach constriction canker, caused by Phompsis amygdali, was studied in two potted experiments, established in April 2003 and February 2005. The `Sprincrest’ cultivar was used because of its medium susceptibility. Four different nitrogen levels were used: N0 — without nitrogen, N1 — insufficient level, N2 — level considered sufficient, and N3 — excessive level. Plant inoculations with P. amygdali were carried out in November. The canker area around the inoculation sites was measured between January and March of the following year and used as susceptibility assessment. In 2003, the average canker size was much higher than in 2005, which probably shows the effects of temperature and precipitation on canker size. The results show that there is an effect of nitrogen fertilisation on plant vigour and therefore on constriction canker susceptibility. Both N0 and N3 increased the canker area.
