Aim: In this study, we tested plant community-based management methods to reduce the abundance of the invasive native plant Jacobaea aquatica (marsh ragwort). As J. aquatica mainly occurs in species-rich wet grasslands, our aim was to define management measures that do not reduce the conservation value of the resident communities. Location: Data we...
Introduction: Allelopathic properties of cane straw are reported, however, information on the effect on some weed species is incomplete Objective: To evaluate the allelopathic effect of sugarcane straw (Saccharum spp. Hybrid) on germination and initial growth of weed (Achyranthes aspera var. Indica L.) under controlled conditions. Methodology: An e...

Xylella fastidiosa Wells et al. (Xanthomonadales: Xanthomonadaceae) is a xylem inhabiting bacterium which is exclusively transmitted by xylem sap feeding insects. Among them, Philaenus spumarius Linnaeus and Neophilaenus campestris Fallén are the most abundant species in Europe. During 2018 and 2019 a survey was conducted in olive groves in Greece ...

To maximize crop growth, crops need to capture sunlight efficiently. This property is primarily influenced by the shape of the crops such as the angle, area, and arrangement of leaves. We constructed a rice (Oryza sativa L.) inbred line that displayed an ideal transition of plant shapes in terms of sunlight receiving efficiency. During vegetative g...
Mots-clés : mortalité, désherbage, sélectivité, mode d'action, cibles biologiques.

Grain corn is the main cereal produced in Portugal. It is grown in intensive monoculture cropping systems that may have negative effects on soil quality, affecting long-term fertility and productivity, and, therefore, the sustainability of the production. A promising management practice to mitigate soil degradation is to grow winter cover crops use...
Abstract Background: The application of synthetic pesticides to the tomato crop (Solanum lycopersicum -Solanaceae-) increases fruit production, but also carries risks for the environment, human and animal health. Hypothesis: local ruderal plant extracts could be an alternative for weed control, with potential applications in agroecology and organic...
Duringthe main cropping season, Ethiopian farmers deliberately weed faba bean (Vicia faba L.) fields much later than recommended and use the weed herbage mass as feed. This study examined the rationale behind farmers’ practices and explored options to further improve productivity. The study involved two experiments. The first compared the overall b...
The present study was aimed at investigating the allelopathic effects of a crude extract from Chromolaena odorata (L.) R.M.King and H.Rob. (Siam weed). The effects of 70% crude ethanol extract from the whole plant, leaf, stem, and root on the germination and growth of Echinochloa crus-galli and Amaranthus viridis seedlings were evaluated using Petr...

Piptocarpha rotundifolia (Less.) Baker stands out as one of the species with the highest frequency, density, and relative dominance in the Cerrado formations. However, no phytochemical studies have been carried out with this species to date. The aim of this study was to evaluate the phytotoxic activity of P. rotundifolia leaves in the search of new...
