IR 24 plants as compared to untreated control plants (Velusamy and Gnanamanickam, 2003). Promoting a healthy growing environment is the best way to prevent your plants from picking up this disease. The role of the plant defence activator, acibenzolar‐S‐methyl (ASM), in inducing resistance in rice against bacterial leaf blight caused by Xanthomonas oryzae pv.oryzae (Xoo) was studied. Xanthomonas oryzae pv.oryzae (Xoo), a causal agent of bacterial leaf blight (BLB), is one of the most important pathogens of rice.The effectiveness of ten Streptomyces spp. Here, we examined biological roles of OsTGA2 (grouped into the same subclade as Arabidopsis TGAs) in bacterial leaf blight resistance. About 90% of the world's rice is produced and consumed here in Asia (Wrigley et al., 2004).In the Philippines, around 43,000 square kilometers of the total 300,000 square kilometers, is devoted and used for rice cultivation and production (IRRI). Bacterial blight is one of the most serious diseases of rice and is especially prevalent in irrigated and rain-fed lowland areas. Application of ASM induced resistance in rice to infection by Xoo.When the pathogen was clip‐inoculated to the rice plants, it caused bacterial leaf blight symptoms in the untreated control. BLB of rice is probably the world in distribution. Out of these, isolates viz., Bacillus subtilis var. Bacterial blight, blast, and sheath blight are the commonest diseases causing substantial yield loss in rice around the world. Bacterial leaf blight of rice. According to Patel et al., 2009, it is one of most devastating disease in both tropical and sub-tropical region in the world. These drops can later dry up and leave a white crust. Other types of blight are more likely to affect edible garden plants like tomatoes and potatoes. oryzae (Xoo) which causes leaf blight disease. Leaf blight symptom can occur at all stages of rice plants. Rice is perhaps the most widely cultivated food crop BB is a vascular disease resulting in a systemic infection2 world over, whose production is constrained by diseases that produces tannish-grey to white lesions along the of fungal, bacterial and viral origin. Keywords: Bacterial Leaf Blight, Simple Sequence Repeats, resistant gene, Nepalese rice, Marker Assisted Screening *Correspondence Author Email: reshamamgain@yahoo.com Introduction Bacterial Leaf Blight (BLB) is one of the productions limiting biotic stresses in rice. Antagonistic bacteria i.e., BRp3 was applied both as seed treatment and foliar spray 1 day before clip inoculation of Xoo pathogen. It can occur in both tropical and tempe. Tests (i.e., biochemical, pathogenicity, or serological) can be done to identify the disease. A field experiment revealed that application of the 2,4-DAPG-producing strains of P. fluorescens as a seed coat treatment reduced bacterial blight lesions in susceptible rice cv. Symptoms: The symptoms appear on leaf blades and sheaths as small linear, water-soaked areas that soon elongated and coalesce into irregular, narrow, yellowish, or brownish stripes. Management of bacterial leaf blight is most commonly done by planting disease resistant rice plants. Common in India and Bangladesh Symptoms There are three main symptoms caused by bacterial blight- leaf blight, wilt and yellow leaf or pale yellow. 3. Front. Spray fresh cowdung extract for the control of bacterial blight. Bacterial leaf blight (BLB) of rice (Oryza sativa L.), caused by season (June-November) and the 1976 dry season (Janu- Nanthomonas oryzae (Uyeda and Ishiyama) Dowson, has recently ary-May), N levels of 0, 60, 120, and 180 kg/ha were tested.

Disease:Bacterial Leaf Blight Xanthomonas oryzae p.v. oryzae (Xoo) causes bacterial blight and Rhizoctonia solani (R. solani) causes sheath blight in rice accounting for >75% of crop losses. Outbreaks of BLB usually occur in irrigated and rain-fed lowland ecologies throughout Asia. In the final stage of infection, milky bacterial ooze can be observed dripping from the leaves. Xoo and Xoc have a special class of type III effectors, called transcription activator-like effectors (TALEs . Surveys of rice growing areas were conducted from 2011 to 2015 with the aim of assessing the importance of bacterial diseases in Benin, Burkina Faso, The Gambia, Ghana, Ivory Coast, Mali, Niger, Nigeria, Senegal, Tanzania and Togo. In wet season, Treatment 3 (Lactic Acid) and Treatment 5 (Soap and water) provided the better pest control on PSB Rc 72H than any other of the treatments. This disease causes substantial yield loss as high as 70% . Yield loss due to bacterial blight can be as much as 70% when susceptible varieties are grown, in environments favorable to the disease. Rice (Oryza sativa) is the leading source of nutrition for more than half of the world's population, and by far it is the most important commercial food crop. CD (P = 0.05). Pathogen: Xanthomonas oryzae pv. Remove weed hosts and plow under rice stubble , straw which can serve as hosts of bacteria. 2005/JP/JP2005_0.rdf.
