Descriptions of fungal diseases include information about the following parasites: downy mildew, white mold, Diaporthe-Phomopsis complex (stem canker, pod and stem blight, seed decay). Other present fungal diseases are only mentioned. Among diseases caused by bacteria, bacterial blight is the most present bacterial disease in our soybean production area. According to soybean diseases caused by viruses, the emphasis in this paper is given to the Soybean Mosaic Virus (SMV) that is present in some of our soybean growing areas, and has been described as well. Other known soybean viruses still haven’t been recorded. Regarding insect pests on soybean, we listed some more important insect pests according to parts of soybean plant they attack.

Od gljivičnih bolesti opisane su plamenjača soje, bijela trulež korijena i stabljike, crna pjegavost stabljike, sušenje mahuna i stabljike te trulež sjemena soje. Ostale prisutne gljivične bolesti su samo navedene. Od bolesti uzrokovanih bakterijama, kod nas je najviše prisutna bakterijska plamenjača, dok ostale bakterioze poznate na soji nisu prisutne kod nas. Od virusnih bolesti prisutan je češće virus mozaika soje (SMV) i on je opisan. Ostali poznati virusi na soji kod nas zasad još nisu potvrđeni. Nabrojani su važniji štetnici po pojedinim dijelovima sojine biljke koje napadaju. Detaljniji opis je dat samo za ekonomski važnije štetnike, koji se kod nas pojavljuju u vrijeme vegetacije soje, a to su: lisne sovice, stričkov šarenjak, rinje te stjenice.
