Featured Articles:Ecological engineering: a new approach for managing rice pests | Geoff Gurr, Charles Sturt UniversityAlthough ‘green revolution’ technologies including modern insecticides have led to increases in average rice yields, the last decade has witnessed a fight-back by insect pests, especially planthoppers (Hemiptera: Delphacidae). Crop losses have resulted as pest populations develop resistance to widely used insecticides and rice variety resistance breaks down. It is estimated that the world’s largest rice producer, China, loses about a million tons of rice paddy from planthopper outbreaks annually. Over recent years, pest damage has been amongst the most important factors leading to crop losses and price rises. Countries such as Vietnam, Brazil, India and Cambodia suspended exports in 2008 to prevent possible domestic shortages. Outbreaks of delphacid pests have occurred each year since that time resulting in crop failures over large areas. Read this article Bacterial Panicle Blight of Rice | Dr. Yeshi Wamishe, University of ArkansasDr. Wamishe's article discusses the work being done in managing the risk of rising temperatures and bacterial panicle blight in rice. This is currently a rising issue and a very important disease of rice that requires attention now before further crop losses are incurred. Efforts towards studying the biology of the bacteria and finding for disease management options are being carried out in several rice research facilities in rice producing states of U.S.A. Dr. Wamishe concludes that resistance would be the best option against this yield-robbing bacterial disease both in developed and developing countries. Read this Article The Rise of the Bakanae Disease of Rice in the Philippines | Christian Joseph R. Cumagun, University of the Philippines Los BañosChristian Cumagun's article focuses on rice in the Philippines and a disease that is seeing increasing occurance. Bakanae or “foolish seedling” in Japanese is a common seedling disease in rice caused by the fungusFusarium fujikuroi. (Gibberella fujikuroi). Due to the threat this pathogen poses to rice security and safety, knowledge about its population structure, aggressiveness and toxin produced may provide knowledge on the biology and evolution of F. fujikuroi and may aid in the development of sustainable disease management strategies.
