Au cours de ces 70 dernières années, certaines substances actives herbicides ont acquis le statut de molécules « pilier » dans la gestion des communautés adventices. En France, jusqu’en 2003, l’atrazine a joué un rôle central dans le désherbage du maïs. Depuis 1974, le glyphosate est devenu la molécule la plus utilisée dans la gestion de l’intercul...

The segetal flora of winter crops includes mostly native or archaeophyte annual species that are often strong specialists of their habitats. Threatened by the intensification of agriculture, segetal flora is particularly valuable from a perspective of biodiversity conservation and evolution. Moreover, it contributes to maintain biodiversity in agro...
Danes se svet bori proti onesnaževanju okolja iz naslova kmetijskih dejavnosti. Največji problem pri zatiranju plevela in zaščiti rastlin povzročajo FFS (pesticides), saj ob nepravilni uporabi škodujemo okolju, pridelkom/krmi in tako posredno tudi človeku oziroma živalim. Največji problem FFS so glikofosfati, ker negativno vplivajo na organizem. Ti...

Millet is a dangerous weed in crop fields. A lack of seed dormancy helps it to spread easily and be present in maize, wheat, and other crop fields. Our previous report revealed the possibility that millet can also play a role as a virus reservoir. In that study, we focused on visual symptoms and detected the presence of several viruses in millet us...
La description des attributs botaniques et éthologiques du patrimoine floristique messicole des agroécosystèmes à l’Aurès, Nord-est d’Algérie s’appuie sur 144 relevés. Cette étude a permis d’inventorier 77 espèces adventices, appartenant essentiellement aux dicotylédones et monocotylédones, réparties en 23 familles botaniques, dont quatre fournisse...

Hexapyrrolohexaazacoronene (HPHAC) is one of the N-containing polycyclic aromatic hydrocarbons in which six pyrroles are fused circularly around a benzene. Despite the recent development of HPHAC analogues, there is no report on direct introduction of functional groups into the HPHAC skeleton. This work reports the first example of nitration reacti...

From noble beginnings as a prospective forage, polyploid Sorghum halepense (‘Johnsongrass’) is both an invasive species and one of the world’s worst agricultural weeds. Formed by S. bicolor x S. propinquum hybridization, we show S. halepense to have S. bicolor -enriched allele composition and striking mutations in 5,957 genes that differentiate it ...
Eucalyptus is a fast-growing, short-cycle, and high-efficiency tree species that is widely planted all over the world. Weeding is a special practice for Eucalyptus plantations that aims to cultivate seedlings and reduce vegetation competition for nutrients. In this study, a typical Eucalyptus plantation was selected as the research object, and the ...

Site-specific weed management and selective application of herbicides as eco-friendly techniques are still challenging tasks to perform, especially for densely cultivated crops, such as rice. This study is aimed at developing a stereo vision system for distinguishing between rice plants and weeds and further discriminating two types of weeds in a r...

Root-knot nematodes (RKN), Meloidogyne spp., have a wide host range and are common in the Mediterranean area. Cultivated lavender (Lavandula angustifolia) was found naturally infested by M. hapla in Kozani area, the first documented infestation of this crop by RKN in Greece. Oxalis pescaprae, a common winter weed in Crete, was found to be a host of...
