- ItemOpen AccessCover crops terminated with roller-crimper to manage Cynodon dactylon and other weeds in vineyards(John Wiley and Sons Ltd, 2023) Cabrera Pérez, Carlos; Royo-Esnal, Aritz; Català, Bruna; Baraibar Padró, Bàrbara; Recasens i Guinjuan, JordiUsing cover crops in organic vineyards can provide many advantages, including weed suppression. However, their effectiveness may depend on the weed community, the cover crop species and the termination method. The most common practice for cover crop termination is shredding, but rapid residue decomposition can allow noxious species like Cynodon dactylon to proliferate during summer and compete with the vines. The use of roller-crimpers as an alternative method can be effective in some cropping systems, but no studies have focused on their use in the inter-row of vineyards. The objective of this study was to evaluate the effectiveness of seven cover crops (spontaneous, Avena strigosa, Hordeum vulgare, Lolium multiflorum, Phacelia tanacetifolia, Sinapis alba and X Triticosecale) and two termination methods (shredding or roller-crimper) in managing C. dactylon during summer. RESULTS: In 2020, rolled A. strigosa, P. tanacetifolia and the spontaneous flora limited the coverage of C. dactylon more than shredding (increases of 3% and 18% in C. dactylon cover from July to September in rolled and shredded cover crops, respectively), while in 2021, rolling was better than shredding for all cover crop species in September (5% and 18% increases, respectively). CONCLUSION: Roller-crimping cover crops was an effective method to control C. dactylon in vineyard inter-rows but it did not consistently work for all cover crops in both years. Our study is one of the first to test the efficacy of roller-crimpers to manage summer weeds in vineyards. © 2023 The Authors.

- ItemOpen AccessHerbicide resistance is increasing in Spain: concomitant management and prevention(MDPI, 2023) Montull Daniel, José María; Torra Farré, JoelHerbicide-resistant weeds currently challenge sustainable food production in almost all cropping systems in Europe. Herbicide resistance is increasing, and some European countries are among the most affected globally, such as Spain and France. This situation is worsening not only due to herbicide use restrictions but also due to climate change, rendering Mediterranean countries such as Spain particularly susceptible. Therefore, focus should be aimed at preventive measures, which include those not only based on integrated weed management strategies but also based on a very good knowledge of the biology and ecology of each weed species. The main objective of this review is to provide an overview of potential future herbicide-resistant cases that can evolve in the near future in Europe. We use Spain as the case study, as it is the most affected country in Europe and because it is at risk due to global warming. For different resistant cases detailed on a crop basis, adequate prevention and management measures will be provided in order to avoid resistance evolution relative to the sites of action that are most likely to generate resistant biotypes due to expected high selection pressures.

- ItemOpen AccessEl cultiu de camelina(IRTA, 2021) Royo-Esnal, Aritz; Codina-Pascual, NoemíLa camelina (Camelina sativa (L.) Crantz) és un cultiu oleaginós conegut i cultivat des de l'Edat de Bronze que va ser reemplaçat per altres cultius més productius cap al segle XVI. Des de fa uns anys, però, i a causa de la necessitat de trobar cultius alternatius que aportin matèria primera per diversos usos, la camelina ha tornat a sobresortir. A més el seu cultiu presenta un interès per formar part de les rotacions de cultius herbacis de secà. Aquest interès no és en va, ja que, per un costat, l'oli produït per aquesta planta es pot utilitzar amb diferents finalitats, des del consum humà i animal fins a la producció de biodièsel, passant per altres usos industrials com la fabricació de pintures i vernissos o, fins i tot, en la indústria cosmètica. Altrament, el tortó de camelina, ric en proteïna, antioxidants i àcid grassos saludables s'utilitza en l'alimentació de truites i gallines (entre altres bestiars), per enriquir la carn dels primers i els ous dels segons amb omega-3. A més, les llavors tenen un contingut de mucílag d'entre un 7% i un 15%, essent una potencial font d'aquest producte per l'ús medicinal i alimentari.
