Soybean (Glycine max) is an annual oilseed crop that is mostly farmed for its edible seeds. It offers 40% of the most affordable source of protein for animal and human feed. The crop suffers from various diseases, reducing its yield either slightly or even eliminating it. The main hindrance to soybean production is the fungus that lives in the seeds. The present study aimed to evaluate the impact of various seed treatments on the control of soybean seed-borne fungus infections. This study used treatments, namely physical therapy by heating the seeds in a microwave at a temperature of 40^oC for 10, 20 and 30 seconds and chemical treatment by soaking the seeds in a fungicide with active ingredient difenoconazole with a concentration of 1%, 2% and 3%. Seeds without heating and as control are soaking fungicides. Each treatment was repeated three times. The seeds that have been given treatments are then planted using the growing test technique and incubated for seven days. Furthermore, the seed viability and the growth of pathogenic fungi were observed at the end of incubation. The results showed that soybean seed germination was not affected by physical and chemical treatments. The seed viability of 100% with or without treatment. This was confirmed by the findings of seed-borne fungi (Fusarium, Alternaria, Saprophyte spp.) with a low infection rate of 0.01-0.19%. Chemical treatment with concentrations of 1%, 2% and 3% had a significant effect on the Fusarium spp. infection level, which was higher than the control, which was 0.18%, 0.17% and 0.19%.
