“…Although it is difficult to separate the influence of environmental, cultural and genetic factors on seed quality, the results of this and related studies (Tekrony et al, 1984; Hershman et al, 1987; Jordan et al, 1988; Rupe, 1989; Wrather et al, 1996) suggest that planting late‐maturing cultivars or delaying the planting of early‐ and mid‐season cultivars may reduce seed infection by Fusarium spp. and Diaporthe/Phomopsis complex.…”

Fifteen soya bean genotypes from maturity groups IV, V and VI were planted on three dates at Manfredi Experimental Station – INTA, Córdoba Province, Argentina. Seeds were harvested at maturity and evaluated for seed infection by Fusarium spp. and Diaporthe/Phomopsis complex, and for physical and chemical parameters. There was a significant negative correlation between planting date (PD) and fungal incidence (P=0.05). A higher percentage of fungal incidence at earlier PD was consistent with lower seed weight and volume, higher oil content and no change in protein content. The highest values of fungal incidence were associated with increased oleic acid and decreased linoleic and linolenic acid contents. These results suggest that planting late maturity cultivars or delaying the planting of early and mid‐season cultivars may reduce seed infection by Fusarium spp. and Diaporthe/Phomopsis complex.

“…Rupe (1989) relatou danos por C. kikuchii em soja variando de 15% a 30%, mas, apesar desse valores, caso a incidência da doença ocorra no estágio de granação da soja, ela pode resultar em chochamento de até 50% no número total de vagens (CÂMARA, 1998). Além da redução na produção, C. kikuchii é um dos principais fungos que afetam a qualidade das sementes de soja (JORDAN et al, 1988). Contudo, a extensão dos efeitos do patógeno na qualidade das sementes depende do isolado de fungo envolvido (PATHAN; SINCLAIR; McCLARY, 1989); logo, o maior prejuízo causado por C. kikuchii é a desfolha antecipada, responsável por diminuir a produção, o que geralmente se deve ao menor tamanho das sementes (FAO, 1995).…”
