The production of biopesticides from plants is done by several techniques, including prolonged maceration, simple maceration or alcoholic extractions, to name but a few. By using eucalyptus extracts we have had an insecticidal, fungicidal effect and for nettle extracts we have had with considerable percentages in experimental fields insecticidal, fungicidal effects. For tobacco extracts we had a herbicidal effect in addition to the insecticidal and fungicidal effects. The study of its toxicity on a weed population gave us an EC90 of 65.459 g/L. The photochemical test carried out allowed us to identify groups of compounds such as alkaloids, polyphenols, saponins and flavonoids.
