"Asian" rust (Phakopsora pachyhrizi) was the most feared disease to affect soybeans in the Western Hemisphere. Since its first detection in South America (Argentina, Brazil and Paraguay in 2001) severe losses have been reported in Brazil and Paraguay. Its spread to the other soybean producing countries in the American Continent is just a matter of time. Bolivia grew about 511 thousand hectares of soybeans during the Summer and 194 thousand hectares in the Winter of 2003. The first occurrence of rust in the country was noticed on the Winter crop, on July 30, 2003, in the Province of Ichilo, Yapacani, State of Santa Cruz. A field of approximately 3 ha of cultivar Sayubu, at growth stage R1 had about 55% of leaf area infected. The field was sprayed with fungicides and later weather condition was not favorable for further disease development or spread to neighboring fields. A new focus was later found on August 30 at Chané, North of Santa Cruz de la Sierra, on 30 ha of cultivar Tucunaré, at growth stage R5.2. The disease severely affected a patch of about 3 ha. In the most affected portion of the field 100% of the leaf area was infected, gradually decreasing away from the patch. Application of fungicide pyraclostrobin + epoxiconazole (66.5g + 25.0g a.i./ha ), at the rate of 0,5 L c.p./ha, controlled the disease where severity was still low (yield of 2,768.30 kg/ha) but no control was noticed where disease was already severe (yield of 957.10 Kg/ha). Though sprayed, yield difference between low and severe rust areas reached 65.4 % and days to harvest maturity differed by 21 days. Throughout the Winter season rust was found on almost all soybean fields but yield losses were not apparent, due to later occurrence and fungicide sprays.
