“…Results of the study are consistent with those from a set of on‐farm experiments conducted in Italy, Germany, and Slovenia, in which blending mechanical and chemical weed control tactics was found to be effective for suppressing weeds in corn with greatly reduced reliance on herbicides, while maintaining yields and economic returns (Vasileiadis et al. ). Importantly, modeling studies predict that more diverse management systems integrating chemical and non‐chemical tactics can not only keep weed population densities lower, but also slow evolution of herbicide resistance (Renton et al.…”

Weed management is a critically important activity on both agricultural and non-agricultural lands, but it is faced with a daunting set of challenges: environmental damage caused by control practices, weed resistance to herbicides, accelerated rates of weed dispersal through global trade, and greater weed impacts due to changes in climate and land use. Broad-scale use of new approaches is needed if weed management is to be successful in the coming era. We examine three approaches likely to prove useful for addressing current and future challenges from weeds: diversifying weed management strategies with multiple complementary tactics, developing crop genotypes for enhanced weed suppression, and tailoring management strategies to better accommodate variability in weed spatial distributions. In all three cases, proof-of-concept has long been demonstrated and considerable scientific innovations have been made, but uptake by farmers and land managers has been extremely limited. Impediments to employing these and other ecologically based approaches include inadequate or inappropriate government policy instruments, a lack of market mechanisms, and a paucity of social infrastructure with which to influence learning, decision-making, and actions by farmers and land managers. We offer examples of how these impediments are being addressed in different parts of the world, but note that there is no clear formula for determining which sets of policies, market mechanisms, and educational activities will be effective in various locations. Implementing new approaches for weed management will require multidisciplinary teams comprised of scientists, engineers, economists, sociologists, educators, farmers, land managers, industry personnel, policy makers, and others willing to focus on weeds within whole farming systems and land management units.

“…In order to address this, a major working group within the European Project PURE (Pesticide Use‐and‐Risk reduction in European farming systems with integrated pest management, http://www.pure-ipm.eu) was devoted to evaluation of various IPM tools for a less pesticide‐dependent European maize production. A detailed study evaluating various integrated weed management tools in different agroenvironments in Europe was published recently as the first outcome of this working group . This paper presents the results of the evaluation of inundative Trichogramma release as an IPM tool for ECB management.…”

Optimally timed mass release of T. brassicae could be considered a sustainable tool for IPM programmes against ECB in southern France and northern Italy. Better involvement of regional advisory services is needed for the successful dissemination and implementation of biological control. Subsidy schemes could also motivate farmers to adopt this IPM tool and compensate for high costs of Trichogramma product.

“…But even if weed escapes happen, in an integrated weed management context, the increase of the seedbank from these weeds could be buffered by crop rotation, the specific crop practices implemented and a higher diversity level of the system (i.e. inclusion of winter and summer crops, cover crops) (Melander et al, 2013;Vasileiadis et al, 2015). A good example comes from a field experiment adjacent to the cylinder experiment (i.e.…”

A cylinder experiment was conducted in northern Greece during 2005 and 2006 to assess emergence dynamics of barnyardgrass (Echinochloa crus-galli (L.) Beauv.) and jimsonweed (Datura stramonium L.) in the case of a switch from conventional to conservation tillage systems (CT). Emergence was surveyed from two burial depths (5 and 10 cm) and with simulation of reduced tillage (i.e. by soil disturbance) and no-till conditions. Barnyardgrass emergence was significantly affected by burial depth, having greater emergence from 5 cm depth (96%) although even 78% of seedlings emerged from 10 cm depth after the two years of study. Emergence of barnyardgrass was stable across years from the different depths and tillage regimes. Jimsonweed seeds showed lower germination than barnyardgrass during the study period, whereas its emergence was significantly affected by soil disturbance having 41% compared to 28% without disturbance. A burial depth x soil disturbance interaction was also determined, which showed higher emergence from 10 cm depth with soil disturbance. Jimsonweed was found to have significantly higher emergence from 10 cm depth with soil disturbance in Year 2. Seasonal emergence timing of barnyardgrass did not vary between the different burial depth and soil disturbance regimes, as it started in April and lasted until end of May in both years. Jimsonweed showed a bimodal pattern, with first emergence starting end of April until mid-May and the second ranging from mid-June to mid-August from 10 cm burial depth and from mid-July to mid-August from 5 cm depth, irrespective of soil disturbance in both cases.
