Controle alternativo de Colletotrichum musae com extrato de mil folhas Alternative control of Colletotrichum musae with extract of yarrow

Plant extracts such as yarrow (Achillea millefolium L.), can help control of post-harvest diseases in Banana (Musa sp.), such as anthracnose (Colletotrichum musae B. & M.A.C.). The objective of this study was to evaluate the inhibition of fungal growth by fractions of different parts of the plant extracts in different months of harvest. The material collected was, separated, dried, crushed and held the ethanol extraction by maceration technique. After obtaining the extract, this was dried, dissolved in dimethylsulfoxide and poured on PDA medium flux. Treatments performed were in triplicate and evaluated the radial growth of the fungus after 5 days under growth chamber (25 ° C). There was a growth reduction of the fungus, compared to the control, obtaining the best results in the polar fractions and the most active parts were the flowers. The constancy of the activity observed in different parts of the plant is indicative of the plant extract potential in controlling anthracnose of banana.
