Previous field results obtained in soybean-wheat crop sequences showed a complementary reduction in Commelina benghalensis weed seedbank and not on Acanthospermum hispidum in areas infested with Brachiaria plantaginea. Analysis of the soluble fraction of B. plantaginea showed aconitic acid (AA) (95%), ferulic acid (FA) and others (5%). Bioessays were carried out at laboratory with the objective of evaluating effects of the pure AA solutions on seed germination, root and stem length and fungi growth on C. benghalensis, A. hispidum, including Euphorbia heterophylla and Ipomoea grandifolia seeds. Pure solutions doses of 0.00, 0.25, 0.50, 1.00 and 2.0 mM were prepared with agar 0,5% and poured into plastic boxes with cover. Seed species were sterilized externaly with hipochloride 2%, sown in the boxes and kept in germination chamber for 12 days. Allelopathic effects of AA were observed reducing germination rate and length of root, mainly of C. benghalensis as comparet to A. hispidum; at 2,0 mM of AA there was also a reduction in germination rate, in radicular and in stem growth of E. heterophylla and I. grandifolia. Additionally AA stimulated the growth of endophytic fungi on the seed surface of C. benghalensis, determined as Fusarium solani (red colour), which were also present over non germinated seeds. A different kind of fungi species was highly stimulated to grow on E. heterophylla, having a green colour. The compound plays an important role in the seedbank reduction of some weeds, acting directly on germination as an allelopathic substance and as a stimulatory substance of endophytic fungi, as a predator, that also contribute to make seeds unviable. Straw of alexandergrass (B. plantaginea) presents a high aconitic acid concentration able to affect germination and growth of some evaluated weeds.
