Abstract A description is provided for Fusarium oxysporum f. sp. albedinis. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Phoenix dactylifera L. (Date palm); possibly Phoenix canariensis (Canary Island palm) and Lawsonia inermis L. (Henna). DISEASE: Bayoud disease (vascular wilt). GEOGRAPHICAL DISTRIBUTION: North Africa: Algeria, Mauritania, Morocco; Europe: France, Italy (on P. canariensis). (IMI Distribution Map 240). TRANSMISSION: The fungus is soil borne, and can survive for many years as chlamydospores in infected soil and plant residues (57, 2620). Within a site, the fungus may spread by root contact between adjacent trees (52, 4186). Between sites the fungus may be disseminated by dispersal of soil, infected plant parts or artefacts made from palm tissues. There is currently no evidence of seed borne transmission.

Bayoud Disease

Abstract Background “Bayoud” disease caused by Fusarium oxysporum f. sp. albedinis (Foa) poses a serious threat to date palm (Phoenix dactylifera L.) in Morocco. However, research studies performed to discover biological methods to control this disease remain limited. The present study has set objectives to determine antifungal activity of five plants extracts (Acacia cyanophylla, Cupressus atlantica, Eucalyptus torquata, Nerium oleander, and Schinus molle) against Foa and link this effect to their content in polyphenols and flavonoids as well as their antioxidant properties. Results Plant extracts showed significant differences (p < 0.05) regarding their antifungal activity. The extracts of E. torquata and C. atlantica showed the strongest antifungal effect resulting in the inhibition of mycelial growth, sporulation, and spore germination in a dose-dependent manner. In addition, there were significant differences among the examined plant extracts in respect to their total polyphenols (1.536–7.348 g GAE/100 g DW), flavonoids (0.986–5.759 g RE/100 g DW), and antioxidant properties measured by Trolox equivalent antioxidant capacity (TEAC) (7.47–38.97 mmol TE/100 g DW) and ferric-reducing antioxidant power (FRAP) assay (8.95–47.36 mmol TE/100 g DW). Moreover, the antifungal potential of plant extracts was found to be moderately to strongly correlated with their polyphenol and flavonoid contents as well as their antioxidant activity, implying that the effective inhibitory activity of these plant extracts is partly due to their richness in antioxidative secondary metabolites. Conclusion Our findings shed further light on plants as a-yet-untapped resource of bioactive compounds and constructed the foundation for the development of new biological approaches to best manage Bayoud disease.

Abstract A description is provided for Fusarium oxysporum f. sp. batatas. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Ipomoea batatas (sweet potato), Nicotiana (tobacco). The fungus may infect a wide range of other plants in Convolvulaceae (63, 1065) and other families, sometimes without causing wilt symptoms. DISEASE: Vascular wilt, sometimes called stem rot. GEOGRAPHICAL DISTRIBUTION: Brazil (62, 525), China, Hawaii, India, Japan, Malawi, New Zealand. The disease occurs in temperate rather than tropical regions. TRANSMISSION: The fungus may survive in soil for many years as chlamydospores. Transmission may occur by means of infected plant material used for propagation, or through contaminated soil.

Abstract A description is provided for Thecaphora solani. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Species of Solanum, including S. tuberosum, S. andigenum and S. stoloniferum; found on clones of S. ajanhuiri, S. curtilobum, S. chaucha, S. goniocalyx, S. phureja, S. stenotomum and S. tuberosum subsp. andigena in the Potato Germ Plasm Bank, Peru (59, 2318); also on Lycopersicon.DISEASE: Potato smut. Infection normally commences in meristematic regions in young shoots, underground portions of stems (commonly at the base of a stem, where it joins the roots), stolons and eventually in tubers, and the resultant galls increase in size throughout the growing season (59, 5337). In tomato plants, hypertrophy and gall formation occur at the junction of stems and roots. GEOGRAPHICAL DISTRIBUTION: North America: Mexico. South America: Bolivia, Colombia, Ecuador, Peru, Venezuela. See CMI Distribution Map 214 (ed. 2, 1967). TRANSMISSION: By infected tubers, also soilborne, the ustilospores released into soil by disintegration of infected plant parts and surviving there.

Bayoud Disease

Background: This work has the objective to biocontrol the bayoud disease of date palm caused by the fungus Fusarium oxysporum f. sp. albedinis (Foa), is the major disease in Algerian palm groves of south western region. This in vivo biocontrol was done on date palm variety Deglet-Nour, using two antagonistic fungi species, Trichoderma harzianum and Aspergillus flavus.Methods: Twenty Foa isolates obtained from isolation of the spines carrying the typical symptoms of Bayoud disease were used. Two strains T. harzianum and A. flavus, were isolated from rhizosphere soils of the date palm trees. Using the greenhouse screening test, which was carried out on 3-4 month-old date palm seedlings at the rate of 5 ml of inoculum suspension.Result: A statistical analysis showed a significant (P less than 0.05), difference of Deglet-Nour seedlings reactions against Foa isolates and antagonistic fungi were observed. All date palm trees present susceptibility against Foa until the total mortality of seedlings. The biocontrol test showed that two antagonists showed different reaction, with the complete resistance for seedlings treated by T. harzianum with the mortality rate (rm%) reduced at 100%, while, the second antagonist A. flavus reduced the rm% at 25%. We can apply of these antagonistic fungi to protect our groves contaminated by Bayoud disease and also contain this susceptible commercial variety.

Abstract A description is provided for Ganoderma applanatum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: A very wide range of broad-leaved and coniferous trees. As much confusion has arisen between G. applanatum and G. adspersum earlier references must be accepted only with care as to the hosts. It is the authors observation that G. applanatum is more frequent in the woodland biotype than in orchards, garden and roadside plantations while G. adspersum seems to be more frequent in the latter. GEOGRAPHICAL DISTRIBUTION: Throughout the northern hemisphere temperate zone. The northern limit follows the tree line. The southern limit is Florida in the USA, the Mediterranean sea in Europe, Northern Iran, Northern Pakistan, southern slopes of the Himalayas, but a specimen has been obtained from Bombay in India. In Pakistan and India it overlaps slightly with the range of G. tornatum (CMI Descript. 447). TRANSMISSION: Transmission is probably confined to air-borne spores and root contact with infected plant material in the soil.
