This study is the first one that examines simultaneously the direct and indirect effects of soil salinity on rice and rice weeds and suggests solutions to secure both rice production and effective weed control. Salinity negatively impairs growth, reproduction, and rice grain yield. Several studies have addressed the effects of salinity on rice yiel...
This article aims to provide a review of major challenges and research needs for the diffusion of conservation agriculture (CA) and the improvement of crop–soil–water conditions in Southern Europe and Northern Africa. A multidisciplinary study and a participatory approach are at the basis of an international project of research and innovation actio...
Lolium spp. are troublesome weeds mainly found in winter cereal crops worldwide, including Europe. In recent years resistant mechanisms have been evolved to several important herbicides. In this study we investigated the mechanisms responsible for conferring glyphosate resistance in some Lolium spp. populations. A holistic approach was used, based...
Annual ryegrass species (Lolium spp.) infest cereal crops worldwide. Ryegrass populations with multiple resistance to the acetyl coenzyme A carboxylase (ACCase) and acetolactate synthase (ALS) inhibitors are an increasing problem in several European countries. We investigated the resistance pattern and level of resistance in ryegrass populations co...
Weed science, as an integral part of agricultural production needs to evolve by moving away from its mono-disciplinary perspective at targeting weeds, sometimes a single species, through the overreliance on few single herbicide mechanisms of action. Herbicides remain a simple and cost-effective way to control weeds but they are rapidly losing their...
Optimizing diquat efficacy with the use of adjuvants may broaden the spectrum of weed control, but relevant research towards this direction is limited. Field and greenhouse experiments were conducted to evaluate the effect of diquat applied alone and with six commercial adjuvants (surfactants and oil-based adjuvants) on various weed species. Diquat...
The repeated use of herbicides with the same mode of action maybe has led to buildup of resistant late watergrass (Echinochloa phyllopogon (Stapf) Stapf ex Kossenko) populations. Thus, pot experiment was conducted to evaluate the level of penoxsulam- and bispyribac-resistance in seven late watergrass biotypes collected from water-seeded rice fields...
Silverleaf nightshade is a difficult-to-control perennial weed. Field experiments were conducted in northern Greece to evaluate the control of silverleaf nightshade with POST applications of glufosinate (1,500 g a.i. ha-1), glyphosate (3,600 g a.i. ha-1), tembotrione (148.5 g a.i. ha-1), and a mixture of tembotrione plus bentazon (148.5 plus 1,440...
Field and pot trials were conducted in two sites of northern Greece (Thermi and Lepti) to study selectivity and weed control in maize (Zea mays L.) with herbicide mixtures based on tembotrione. Treatments included tembotrione (plus isoxadifen-ethyl safener) applied alone at 100 g ai/ha and three mixtures of tembotrione with: (i) rimsulfuron at 10 g...
Climate change is caused by the release of greenhouse gases in the atmosphere. Climate change will impact many activities, but effects on agricultural production could be acute. Estimates of annual damages in agriculture due to temperature increase or extended periods of drought will be more costly than damages in other activities. Yield losses are...
Panicoid grasses are major weeds of maize and sugarcane as well as of several other important grains, including sorghum, pearl millet, and foxtail millet. Pot trials were conducted to study the activity and potential interactions of topramezone in mixture with recommended rates of rimsulfuron or nicosulfuron on three annual panicoid grasses (i.e. E...
The effect of five adjuvants (non-ionic surfactant, paraffinic oil, vegetable oil,
mixture of fatty acids methyl esters plus surfactant blend, and organosilicone) on diquat
efficacy was assessed on poverty brome, sterile oat, and Italian ryegrass in field and pot
experiments. All tank mixtures with diquat increased diquat efficacy from 50-54% to 77...
Water smartweed, an uncommon but troublesome perennial weed of the knotweed family (Polygonaceae), has been endemic with its terrestrial growth form in the area of Kato Nevrokopi in northern Greece, one of the most important potato-growing areas of the country. Two field trials were conducted in 2011 to study the response of water smartweed, wild b...
The versatile rhizomatous terrestrial form of the perennial weed Persicaria amphibia is reported to cause severe infestations
in potato crops, which are mainly cultivated as a monoculture in the area of Kato Nevrokopi located at the Greek–Bulgarian
boundaries. This weed cannot be easily eradicated from potato crops in Northern Greece and therefore,...
Essential oils obtained from lavender (Lavandula x hybrida Rev.), sweet fennel (Foeniculum vulgare Mill) and thyme (Thymus capitatus L.) were tested in vitro for their allelopathic effect on germination and radical growth of two winter cereals, wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) and two important grass weed species of thes...
The herbicidal effect of Satureja hortensis L. and Melissa officinalis L. essentialoils was tested on germination and root length of two grass weed species, Lolliumrigidum L. and Phalaris brachystachys L., under laboratory conditions. Carvacrol and citral were the main constituents of the essential oil of S. hortensis and M. officinalis, respective...
Topramezone is a new herbicide for post-emergence control of broadleaf and grass weeds in maize. Two field experiments were conducted in northern Greece in 2008 and 2009 to determine the response of grain maize to topramezone applied with the adjuvant DASH at 2–4, 4–6 and 6–8 maize leaf stage. In both years, plant height, cob number and yield were...
Dose–response experiments were conducted in glasshouse pot experiments to investigate the selectivity of oxadiargyl, a recently introduced herbicide, in direct-seeded rice under both aerobic and anaerobic conditions. Crop sensitivity to oxadiargyl was comparatively greater for wet-seeded (anaerobic) than for dry-seeded rice (aerobic). Likewise, gre...

This Special Issue intends to cover recent progress in different aspects related to the implementation of CA in a wide range of cropping systems across different agro-ecologies in the Mediterranean area. (https://www.mdpi.com/journal/agriculture/special_issues/GPJII9A4LJ)
The CAMA project aims to identify the main barriers that hinder the adoption of Conservation Agriculture (CA) adoption by smallholders of Mediterranean countries and to overcome them by a participatory research approach based on the use of field experiments and pilot case studies in several conditions and the development of an extensive programme of dissemination and training. It is a PRIMA project coordinated by CREA Italy with 13 partners. From Greece the partner is the Hellenic Agricultural Organization-Demeter (HAO-Demeter)
