Pseudomonas Lachrymans

Abstract A description is provided for Pseudomonas lachrymans. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Cucumis sativus and C. anguria. It may also attack C. melo var. inodorus (26: 140) and some other cucurbits. Elliott (31: 105) lists 10 hosts, all in the Cucurbitaceae. DISEASE: Angular leaf spot of cucumber. Small water-soaked spots appear on the leaves, petioles, stems, and fruits. On leaves they enlarge and become angular as they are delimited by veins They become tan to brown and the necrotic centres may fall out. On petioles, stems, and fruit spots develop white crusty bactenal exudate. A fruit rot develops if the bacteria penetrate deeply. GEOGRAPHICAL DISTRIBUTION: North and parts of Central America, most of Europe, U.S.S.R., China, Japan, W. Australia, Israel, southern Africa. (CMI Map 355, ed. 2, 1964). TRANSMISSION: The pathogen is seed-borne and infects the cotyledons dunng germination. It can overwinter on infected crop residue in the soil and has been found viable in dry leaf matenal after two and a half years (36: 677). The bacteria are carried from plant to plant within a crop by rain splash and probably by insects (Carsner, 1918; 31: 272). Workers can also spread the disease, particularly when foliage is wet with rain or dew (35: 810).

Abstract A description is provided for Drechslera incurvata. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Cocos nucifera. DISEASE: A leaf spot of young coconut (Cocos nucifera). The spots are at first small, oval, brown; enlarging and becoming pale buff in the centre with a broad, dark brown margin. In severe attacks the edges of leaves become extensively necrotic. GEOGRAPHICAL DISTRIBUTION: Apart from records from Jamaica and Seychelles the fungus has been reported only from S.E. Asia, Australasia and Oceania: British Solomon Islands, Fiji, French Polynesia, Malaysia (W., Sabah, Sarawak), New Caledonia, New Hebrides, Papua-New Guinea, Philippines, Sri Lanka, Vietnam and Thailand. TRANSMISSION: Presumably air dispersed.

Abstract A description is provided for Alternaria citri. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Citrus spp. DISEASES: Black rot of oranges; fruit rot of lemons and tangerines, leaf spot of rough lemon and Emperor mandarin. Probably found in general on Citrus spp., especially fruit. Internal decay in oranges begins near the styler end. There is no external sign of this but infected fruit tend to colour prematurely and some may drop. The condition may be aggravated by weather and host nutrient balance. On lemons a soft, central rot occurs in mature fruit, beginning at the button and spreading to the axis. The rind becomes translucent before the rot appears on the surface. There is also an end rot in which the external spread is almost as extensive as that inside the fruit. On leaves of rough lemon circular or irregular necrotic spots with concentric zoning are produced. A general chlorosis, curling and leaf drop follow. GEOGRAPHICAL DISTRIBUTION: The fruit rotting form is widespread although other forms may be of more limited distribution. TRANSMISSION: Presumably air-borne but no dispersal studies appear to have been reported.
