ABSTRACT

Cucumber has been an essential vegetable crop in the world being affected by Pythium, fusariium and phythophtora. Root and stem rot of cucumber (Cucumis sativus), caused by Fusarium oxysporum f. sp. radicis-cucumerinum, is a new catastrophic disease of greenhouse crops in Greece and some other countries Fusarium oxysporum causes rotting of roots, lower stems and pythium also causes seedling damping off which is widely spread across cropping soils. Fusarium root and stem rot occur mostly under the condition of periodic low tempereature, habitat and soil compaction. The effective disease control methods available are the use of resistant, biological, chemical control and sanitation.
