Abstract A description is provided for Xanthomonas oryzae pv. oryzicola. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Oryza sativa, Oryza spp. ; Leersia spp., Leptochloa filiformis, Paspalum orbiculare, Zizania aquatica, Z. palustris and Zoysia japonica (Poaceae). DISEASE: Bacterial leaf streak of rice. The bacterium enters leaves through stomata and wounds (particularly those from insect attack) and multiplies in the sub-stomatal cavity and intercellular spaces in the parenchyma. Eventually, parenchyma is replaced by bacterial masses. Narrow, dark greenish, water-soaked streaks of various lengths appear between the veins. Minute amber droplets of bacterial exudate are commonly found on these lesions. Later the lesions extend and coalesce, giving large brownish patches. There are no records of symptoms on infected seeds. In the late stages symptoms are difficult to distinguish from bacterial leaf blight, lesion margins remaining linear rather than wavy as for the latter. Infection is favoured in rainy conditions or during periods of high humidity. GEOGRAPHICAL DISTRIBUTION: AFRICA: Madagascar, Nigeria, Senegal. ASIA: Bangladesh, Cambodia, China (Fujian, Guangdong, Hainan, Hunan, Taiwan, Zhejiang), India (Bihar, Karnataka, Madhya Pradesh, Maharashtra, Uttar Pradesh, West Bengal), Indonesia (Java, Kalimantan, Sulawesi, Sumatra), Laos, Malaysia (Peninsular Malaysia, Sabah, Sarawak), Myanmar, Nepal, Pakistan, Philippines, Thailand, Vietnam. AUSTRALASIA: Australia (Northern Territory). EUROPE: Russian Federation. TRANSMISSION: Seedborne. There is some evidence of survival on crop debris and in association with weeds. The pathogen spreads within a crop in surface moisture, irrigation water, rain, etc. There is some evidence that the disease cycle can be broken by sowing summer seed in the winter season as it is thought the pathogen cannot become established during the cool, dry, winter weather (RAO, 1987).

Abstract A description is provided for Xanthomonas oryzicola. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Oryza saliva. Some weed species of Oryza have also been reported to be susceptible (45, i789). Weakly pathogenic to Leersia hexandra by artificial inoculation. DISEASE: Bacterial leaf streak of rice. Narrow, dark greenish, water-soaked streaks of various lengths appear between the veins. Minute amber droplets of bacterial exudate are commonly found on these lesions. Later the lesions extend and coalesce giving large brownish patches. In the late stages symptoms are difficult to distinguish from bacterial leaf blight. GEOGRAPHICAL DISTRIBUTION: Confined to tropical Asia. Reported from China, India, Philippines, Thailand and West Malaysia (CMI Map 463 and 49, 144).TRANSMISSION: The pathogen spreads within a crop in surface moisture and may enter the leaf through minor abrasions or stomata. Warm wet weather is favourable to both spread and development of the tisease. Introduction into new areas can occur in seed from infected plants (48, 1693).

Abstract A description is provided for Xanthomonas oryzae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Oryza sativa. Natural infection of Leersia oryzaides, Leersia oryzaides var. japonica and Zizania latifolia[Zizania aquatica] is known (Mizukami & Wakimoto, 1959). Natural infection of Cyperus rotundus and C. difformis was reported in India (48, 460), but inoculation of these hosts in the Philippines failed (48, 1689). By inoculation many wild species of Oryza (45, 1789), Leptochloa filiformis (48, 1689), L. chinensis, L. panacea and Zizania aquatica (48, 1683) have all been found susceptible. DISEASE: Bacterial blight of rice and kresek disease of rice. Blight most commonly appears on leaves of young plants, after planting out, as water-soaked stripes at the margins. These enlarge and coalesce to give the characteristic yellowish lesions with wavy edges that occur mainly along the margins of the upper parts of the leaves. These lesions may later expand to cover much of the leaf, which turns whitish or greyish and dies. Leaf sheaths of the more susceptible varieties may be affected. Kresek, which occurs in tropical regions, is a strong systemic infection in which leaves or whole young plants wither and die. In older plants the leaves become pale yellow. GEOGRAPHICAL DISTRIBUTION: Limited to Asia (CMI Map 304, ed. 2, 1964). Occurrences not shown on this map include Korea, Taiwan and Indonesia (Mizukami & Wakimoto, 1969). TRANSMISSION: Spread locally by wind and rain and also by flood and irrigation waters; gains entry to the field in infected planting material, to the nursery in seed, and to both nursery and field from volunteer rice plants and weed hosts usually via the irrigation water. Overwintering may occur on volunteers, on or in the rhizospheres of weed hosts, in stored infected straw and in seed, but it is unlikely in soil and plant debris exposed to the weather, at least under Japanese conditions (Mizukami & Wakimoto, 1969). Infection is through hydathodes and wounds. Penetration through stomata results in a build-up of bacteria in the intercellular spaces, but it is not until they have been exuded on to the leaf surface and re-admitted through the hydathodes and thence into the vascular system, that symptoms of the disease appear (46, 2720).
