Phytotoxic effects of Melia azedarach L. (meliaceae) fruit extract on weeds and crops

In our continuous search for bioactive products obtained from plants with agrochemical prospects, the extract of Melia azedarach L. Fruits was tested for the phytotoxicity against weeds and crops. In a paper disk assay, this extract inhibited the seed germination of Avena saliva L., Brassica napus L...

QD Química In our continuous search for bioactive products obtained from plants with agrochemical prospects, the extract of Melia azedarach L.
