Ocorrência de fungos em sementes de plantas medicinais, aromáticas e condimentares da família Lamiaceae

Abstract

In view of the importance of seeds as carriers of fungi that may transmit diseases to plants, 117 seed samples of the family Lamiaceae were evaluated. Rosemary, lavender, lemon balm, hyssop, basil, marjoram, peppermint, oregano, sage, summer savory and thyme samples were analyzed using blotter test. In these analyses, fungi were detected in 71.8 % of the samples, involving the 24 genera, including Alternaria, Bipolaris, Colletotrichum, Exserohilum Fusarium and Phoma. Among the important plant pathogens, Fusarium oxysporum in basil, F. solani in basil and oregano, Colletotrichum gloeosporioides in hyssop, basil and peppermint and Bipolaris sorokiniana in thyme and basil were detected. Considering that 47.9 % of the analyzed samples were treated with captan fungicide, it can be concluded that the sanitary quality of the evaluated seed samples is not satisfactory.
