Conteúdo: 	Diseases have reduced soybean production in the world for many years, and they will continue to reduce production unless research efforts are expanded to provide more effective controls. Scientists must focus on the management of soybean diseases that cause extensive losses, especially when funds for research are limited. In order to focus funding and research efforts on the most insidious diseases, a clear picture of the magnitude of losses each disease has caused is necessary. A time-lapse picture, covering several years, is needed because the importance of individual diseases can vary over years. The objective of this project was to determine the major soybean disease problems in the top 10 soybean producing countries in 1994 and 1998. The specific goal was to estimate the soybean yield losses caused by individual diseases in each of these years. The percent yield loss estimate due to individual diseases were solicited in 1994 and 1998 from scientists in the United States, China, Brazil, Argentina, India, Canada, Paraguay, Indonesia, Italy, and Bolivia. These estimates of percent of soybean yield losses to various diseases were based on field surveys, plant disease diagnostic clinic samples, variety trial data, information from field workers and university extension staff, research plots, grower demonstrations, and private crop consultant reports. Yield loss estimates due to a particular disease varied by country and between  years. For example, yield losses due to rust were reported from China and Indonesia in 1994 and 1998, but no losses due to this disease were reported from any of the remaining eight countries. Total yield losses caused by Heterodera glycines in these 10 countries were greater than those caused by any other disease in 1994 and 1998. This nematode was not known to be present in Argentina in 1994, but it is now recognized for causing serious yield losses in many parts of the country.
