Breeding for resis-tance In the final stage of infection, milky bacterial ooze can be observed dripping from the leaves. Reduction in rice yield may be as high 50% was also recorded, when the crop was severely infected. al. Rice cultivars, Jyothi and IR50, which are high yielding but highly prone to bacterial blight (BB) caused by pathogen populations of Xanthomonas oryzae pv. Abstract. This research is significant as it is able to create an environmental-friendly protocol to deal with rice bacterial blight instead of using toxic chemical insecticides. Bacterial blight is a major disease of rice. Bacterial blight is one of the most serious diseases of rice. Breeders have played a major role in developing resistant rice varieties against the BLB infection which has been adjudged to be a major disease causing significant yield reduction in rice. However, zinc thiazole is highly insoluble in water and in most organic solvents. The present study aimed to develop inocula, based on native antagonistic Seed and Seedling: Water Mold (Achlya spp. Bacterial blight (BB) caused by Xanthomonas oryzae pv.oryzae (Xoo) is one of the major diseases affecting rice production.

Most of these varieties, however, did not have the optimum cooking quality that was possessed by many of the traditional varieties they replaced. Rice (Oryza sativa L.) is a staple food crop, feeding more than 50% of the world’s population. Distribution Except for Maharashtra, where the endemic area was estimated to be about 0.5 per cent of a total of 1,885,099 acres (Anonymous, 1964), no survey has been made to estimate the oryzae (Xoo) is a major disease of rice in several countries. Citrus blight, caused by an unknown agent, infects all citrus scions.
