Abstract A description is provided for Septoria oenotherae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. DISEASE: Leaf spot. In seed stocks, conidiomata are usually encountered on fragments of pods, stems or leaves, and only rarely on the seeds (SIMPSON et al., 1995). Development of S. oenotherae leads to severe blight, with drying of all the leaves starting from the bottom of the plant. This reduces vitality of the plant, and may cause its death. HOSTS: Calylophus sp., Camissonia sp., Gaura sp., Godetia grandiflora, Ludwigia sp., Oenothera biennis (syn. : Onagra biennis), Oenothera decumbens, O. lamarkiana, O. muricata, O. odorata, O. sinuata (Onagraceae). [Type host - Oenothera biennis.] GEOGRAPHICAL DISTRIBUTION: Asia: Armenia, Azerbaijan, Republic of Georgia, Kazakhstan, Korea, Russia (Far East). Australasia: New Zealand. Europe: Belgium, Czech Republic, Denmark, Estonia, Germany, Italy, Hungary, Latvia, Lithuania, Moldova, Netherlands, Poland, Portugal, Romania, Russia, UK, Ukraine. North America: Canada (Ontario), USA. TRANSMISSION: By air-borne or splash dispersed conidia from infected plant débris and seed stocks. Septoria oenotherae can be transmitted by infected débris in evening primrose seed stock; disease progress may then be influenced by variety, sanitation and chemical fungicides; further, the low rL (apparent infection rate) values can be taken as indicative of a primarily rain-splash spread disease (SIMPSON et al, 1999).

Parietaria Officinalis

Abstract A description is provided for Septoria urticae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. DISEASE: Leaf spot, severe foliar necrosis, defoliation. Sometimes spots eventually fall out and leave a round shot-hole (GROVE, 1935). In inoculation experiments the fungus has caused complete wilting of the leaves followed by the intense defoliation. The disease can affect plant growth and can considerably reduce numbers of seeds produced (DAL-BELLO et al., 1993). HOSTS: Laportea canadensis, Parietaria officinalis, Urtica angustifolia, U. cannabina, U. chamaedryoidis, U. dioica, U. gracilenta, U. gracilis, U. lyallii, U. pilulifera, U. urens (Urticaceae).

AUSTRALASIA: Australia.

TRANSMISSION: Not reported, but almost certainly by airborne or splash-dispersed conidia, also from infected plant debris. Successful application of spore suspensions in water and humid chambers in inoculation experiments with S. urticae confirms the role of moisture in infection transmission.

Abstract A description is provided for Arthrocladiella mougeotii. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. DISEASE: Powdery mildew of Lycium species only. The mycelium, conidiophores, conidia and ascomata form first white, then dirty-grey patches on damaged green parts of the host. Infected parts are deformed slightly and, in cases of high infection, plants can lose their ornamental qualities. Damaged leaves can fall prematurely. HOSTS: Lycium barbarum (= L. europaeum), L. chinense, L. dasystemum, L. halimifolium, L. ovatum, L. potaninii, L. rhombifolium, L. ruthenicum. [Type host - Lycium barbarum] GEOGRAPHICAL DISTRIBUTION: Africa: Canary Islands. Asia (temperate areas only): Armenia, Azerbaijan, China, Republic of Georgia, Israel, Japan, Kazakhstan, Kirghizistan, Korea, Russia (Russian far east), Tadzhikistan, Taiwan, Turkey, Turkmenistan, Uzbekistan. Australasia: New Zealand (introduced). Europe: Austria, Belgium, Bulgaria, Czech Republic, Estonia, France, Germany, Hungary, Italy, Netherlands, Norway, Poland, Rumania, Slovakia, Sweden, Switzerland, UK, Ukraine (southern), former Yugoslavia. North America: USA (introduced). TRANSMISSION: By wind-dispersed conidia. The rôle of ascospores in disease transmission is unknown, although it has been supposed that they can cause the initial stage of the disease.

Abstract A description is provided for Peronospora rumicis. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Emex spinosa, Polygonum convolvulus, Rumex acetosa, R. acetosella, R. alpestris (= R. arifolius), R. auriculatus, R. aviculare, R. hastatus, R. lunaria, R. longifolius, R. montanus, R. patienta, R. polyanthemus, R. repens, R. scutatus, R. thyrsifolius, R. tuberosus, R. vesicarius. DISEASE: Downy mildew of Rumex. Both leaves and flowers are infected. On R. acetosella, the plant remains upright following infection and the upper leaves crumple. In other Rumex species, infected leaves become covered in a very dense layer of violet-coloured felt on their undersurface, whereas a grey felt layer develops on flowers. Leaves become yellowish and their margins roll back (39, 159). GEOGRAPHICAL DISTRIBUTION: Africa: Libya, Morocco, South Africa. Asia-Temperate: Azerbaijan, Republic of Georgia, Israel, Kazakhstan, Kirghizistan, Stavropol. Asia-Tropical: India. Australasia: New Zealand.
