Management of False Smut Disease of Rice: A Review

Rice (Oryza sativa L.) is the most important food crop of the developing world. Among the biotic stresses of false smut is an emerging disease caused by Ustilaginoidea virens. The disease reduces both the quality and quantity of rice. The pathogen produces mycotoxins that are harmful to animals and humans. The disease is severe when favorable environmental conditions like high humidity (more than 80%) and temperature ranging from 25 to 30°C, late sowing and high soil fertility as well as using high amount of nitrogen. It has gained the status of a major disease of rice and causing varying yield loss depending on the weather conditions during the crop-growing period and the genotypes. Therefore, the primary concern of the farmers is the disease management methods, which are effective, simple and practical. Since, there is no single effective management strategy for false smut, we have discussed about the potential management options available depending upon the economic status and adoption capacity of the farmers. In the Plant Pathologists point of view, eco-friendly methods of disease management like cultural, biological and use of resistant variety should be advocated for sustainability of agriculture and human being

Post Flowering Stalk Rot Complex of Maize - Present Status and Future Prospects

Post flowering stalk rot complex is one of the most serious, destructive and widespread group of diseases in maize and yield losses range from 10 to 42% and can be as high as 100% in some areas. PFSR nature is often complex as a number of fungi (like Fusarium verticillioides cause Fusarium stalk rot, Macrophomina phaseolina cause charcoal rot, Harpophora maydis cause late wilt) are involved in causation of the diseases. To combat this problem, identification of quantitative trait loci for resistance to PFSR would facilitate the development of disease resistant maize hybrids. Moreover, various chemical and biological control methods have been developed but ma¬jor emphasis is on development of maize cultivars with genetic resistance to for environment friendly control of the Post flowering stalk rot complex. The current paper reviews the information on distribution, impact of the disease, symptoms, epidemiology, disease cycle; genetics of resistance and integrated disease management approaches has been enumerated to understand the present status of knowledge about PFSR complex and will try to focus on the future perspectives available to improve PFSR management

Educational Intervention among Barbers about Liver Cancer-Inducing Viruses: A Pilot Study from a Developing Country

Liver cancer is among the most prevalent cancers in the world and it is mainly related to the hepatitis B virus (HBV) and hepatitis C virus (HCV). This study evaluated the effectiveness of educational intervention on knowledge and practices regarding hepatitis B and hepatitis C among barbers. After completion of baseline interviews of 70 barbers in Karachi, Pakistan, a 30-min educational session was conducted. The same sessions were repeated twice for all barbers at an interval of 1 month each for reinforcement. Post-intervention interviews were conducted after 1 month of the last session. Before intervention, only 11.4% of the study participants had scored good about the knowledge of HBV, which improved to 74.3% after intervention (p \u3c 0.001). Similarly, for HCV, significant improvement was observed after intervention. Regarding the safe practices to prevent HBV and HCV infections, \u3c 2% had scored to the level of good at baseline, which improved to 48.6% after intervention (p \u3c 0.001). Educational interventions to prevent cancer-induced viruses are highly effective even in illiterate/low-educated people
