Pests and diseases of cucumber in Greece and Europe: symptom description, epidemiology and quarantine status

Downy mildew, powdery mildew with two causal agents and opposite temperature optima, scab, anthracnose, Didymella with a one-hour free-water limit, Botrytis, Sclerotinia. The two fusarium diseases of cucumber: f.sp. radicis-cucumerinum, described in Heraklion with an optimum of 17 degrees and stopping at 32, and fusarium wilt, which starts where that one stops.

Whiteflies, spider mite, thrips, aphids, leafminers, lepidoptera and nematodes, with the Greek resistance data, the Ierapetra nematode populations that overcome the Mi gene, and an explicit statement for every threshold that does not exist. A table of temperature optima by season of the Greek greenhouse. Seven photographs, eighty-four references, each declared as full text or abstract only.
