Soybean (Glycine max L. Merr.) is an important raw material to manufacture balanced concentrates for the animal feed industry in Colombia, particularly for the poultry and pig (swine) production chains.In 2018, approximately 40% soybean plants (cultivar BRS Serena) presented pod and seed decay (Figure 1) at a commercial field in the locality of Puerto Lopez (Meta, Colombia).Specimen collection was conducted according to the permit granted to AGROSAVIA under ANLAS' Resolution No. 1466 of December 03, 2014, Colombia.The affected seeds were cracked, shriveled and covered with chalky white mold (Figure 1).Small tissue pieces (5-mm diameter) from the margins of necrotic lesions on pods were surface disinfested, placed on potato dextrose agar (PDA; pH=4.5), and incubated at 25ºC in darkness.Likewise, infected seeds were used to isolate fungal pathogens according to the protocols of the International Seed Testing Association (2).Three isolates from pods (AGSV-7 to AGSV-9) and four isolates from seeds (AGSV-10 to AGSV-12, and 283-107) were obtained and purified by culturing single hyphal tips.On PDA media, all isolates produced compact fluffy white colonies with aerial mycelium and numerous black clusters of stromata and pycnidia.Single-celled alpha conidia (n =50), observed after 20-day growth on PDA, measured 5.3 -7.2 μm (6.4 ± 0.4 μm) × 2.0 -3.0 μm (2.5± 0.4 μm), were fusiform to ellipsoidal and had two guttules at each end.Beta-conidia (n=50), observed after 40-day growth on PDA, measured 22.0 -30.0 μm (25.30 ± 3.4 μm) × 1.0 -1.2 µm (1.16 ± 0.2 μm).On 1.5% water-agar added of soybean stem pieces, alpha conidia (n =50)
