Morus alba

Common name: White Mulberry

Symptoms induced in controlled conditions (fumigation with ozone)

Fumigation of Morus alba with enhanced ozone levels in Open Top Chambers (OTCs) produced brown interveinal stippling. These leaves a representative of a relatively mild ozone effect, as more severe symptoms have sometimes been observed in the field (see below).
