Abstract: The field investigation and systematic observation on soybean phytophthora rot showed that the disease occurred mainly in southern Fujian.It caused greater damage to the soybeans planted in the spring,possibly related to the precipitation and the number of rain days from April to June.Soybean phytophthora rot was more serious in the continuous cropped fields.Differences in disease-resistance among varieties of the soybeans also existed.
