This study evaluated the bioherbicidal potential of wild fungi grown on microalgal biomass from the digestate treatment of biogas production. Four fungal isolates were used and the extracts were evaluated for the activity of different enzymes and characterized by gas chromatography coupled with mass spectrometry. The bioherbicidal activity was assessed by application on Cucumis sativus, and the leaf damage was visually estimated. The microorganisms showed potential as agents producing an enzyme pool. The obtained fungal extracts presented different organic compounds, most acids, and when applied to Cucumis sativus, showed high levels of leaf damage (80-100 ± 3.00%, deviation relative to the observed average damage). Therefore, the microbial strains are potential biological control agents of weeds, which, together with the microalgae biomass, offer the appropriate conditions to obtain an enzyme pool of biotechnological relevance and with favorable characteristics to be explored as bioherbicides, addressing aspects within the environmental sustainability.

A nanoemulsion was fabricated from Cananga odorata essential oil (EO) and stabilized by incorporation of Tween 80 using ultrasonication. The major constituents of the EO were benzyl benzoate, linalool, and phenylmethyl ester. Differing sonication amplitude (20-60%) and time (2-10 min) were assessed for effects on nanoemulsion droplet size and polydispersity index (PI).

Invasive weed species exhibit both advantages, such as the potential for allelochemicals in bioherbicide development, and risks, including their threat to crop production. Therefore, this study aims to identify an allelochemical from , an invasive weed species. The dose-dependent effects of shoot and root extracts (SSE, SRE) on the signaling in the forage crop and germination in various weed species (, , , , and ) were evaluated.

Weeds are one of the main problems causing losses in agricultural crops, which are nowadays mainly combated by the massive use of chemical herbicides. The development of new effective, sustainable, environmentally and health-friendly bioherbicides is a fundamental need worldwide. In this work, hydrolates and lavandin distilled straws produced during the distillation of the essential oil of lavandin (Lavandula x intermedia) were tested as potential bioherbicides.

The use of chemical herbicides induces negative impacts on the environment, animals, and human health. It also leads to the development of herbicide-resistant weeds. In this context, natural and efficacious herbicides are highly sought after.
