Twelve algal species belonging to Chlorophyta (6), Halophyte (1) and Rhodophyta(4) were screened for their antiphytoviral activity against cucumber mosaic virus (CMV) infected cucumber plants. They collected from the red sea at Yanbua shore, Kingdom of Saudi Arabia. Ethyl alcohol extracts or Lectin preparations of Ulva linza, Enteromorpha intestinalis, Cladophora glomerata, Caulerpa verticillatta, Chara blatic Nitella cernua
(Chlorophyta), Ectocarpus  globifer, Dictyota dichotoma, Fucus vesiculosus, Fucus serratus, Sargassum vulgare (Phaeophyta), Polysiphonia sp. (Rhodophyta)
were tested in vitro and in vivo against the infectivity of CMV. Induction of resistance in cucumber plants were recorded as treatment were done before virus inoculation at different periods. Also acquired resistance against CMV was observed as the cucumber seeds were soaked in algal extracts at different periods. The chlorophyll contents of the treated cucumber plants were more or less similar with that recorded in healthy plants.
