“…Results of the interviews made with the farmers revealed the reliance of growers on cereal monocropping under rainfed conditions, which may be attributed to the high price of the durum wheat in Tunisian market, thus making continuous wheat cropping the most adopted practice by farmers of the region. However, such cultural practice usually selects for weeds species having phenological and physiological similarities to the crop [ 18 , 19 ]. This may explain the abundance of G. coronoria , among others weed species in the fields continuously sown with winter wheat.…”

“…In fact, the deep soil disturbance resulting from plowing decreases the germination and the emergence rates of low dormant weed seeds [ 18 ], leading to a decrease in the spreading of weeds throughout the field. Despite the effect of soil tillage in reducing weed infestations, conventional tillage used in monocropping systems still remains ineffective to avoid the risk of the occurrence of herbicide resistance [ 19 ].…”

Glebionis coronaria (L.) Cass. ex Spach is a troublesome weed in cereal cropping systems in northern Tunisia. Recently, failures in controlling this weed have been reported by farmers. Field surveys and farmers interviews were conducted to highlight the potential causes of G. coronaria occurrence and the associated yield losses in wheat. Survey results revealed a significant correlation between farmers’ awareness of resistance occurrence and cultural practices, mainly sowing date and tillage, while G. coronaria abundance was related to the lack of herbicide rotation and the frequency of ALS-inhibiting herbicide use. High G. coronaria infestations (more than 20 plants/m2) caused a significant decrease in wheat grain yield, reaching almost 75% at a density of 100 plants/m2. Field and pot experiments showed low efficacies of ALS-inhibiting herbicides to control G. coronaria populations. The application of field rates of tribenuron-methyl and mesosulfuron + iodosulfuron failed to control the tested populations, and generally, G. coronaria dry weight increased compared to nontreated ones (potential hormetic effect). These findings were further investigated in two selected resistant populations through tribenuron dose–response experiments, plants from both populations exhibited high resistance factors (greater than 300), surviving up to 16-fold the recommended field dose. This is the first report for G. coronaria resistance occurrence to ALS-inhibiting herbicides in Tunisia and the second case worldwide.

“…Repetitive long-term application of herbicides with the same mode of action, mostly aceto-lactate synthase (ALS) inhibitors, together with the adoption of improper farm management strategies and measures, has resulted in the evolution of herbicide resistance in A. spica-venti as well as in many other weed species worldwide (Massa et al, 2013). The first recorded cases of herbicide resistance in A. spica-venti were to isoproturon in a biotype from Switzerland in 1994 (Mayor, Maillard, 1997) and subsequently in Germany (Niemann, 2000).…”

For decades, farmers have been increasingly reliant on herbicides for effective weed management. Repetitive longterm application of herbicides with the same mode of action has resulted in the evolution of herbicide resistance woldwide. The crops most affected by weed resistance in Europe are winter cereals, and one of the worst weeds is silky bent grass (Apera spica-venti (L.) P. Beauv.). Seeds of A. spica-venti were collected from across Lithuania from the farmer's fields, where this weed was not controlled despite herbicide application. A total of 159 populations of A. spica-venti were tested in greenhause studies over the period of 2016-2018. In the experiments, the resistance of A. spica-venti to the following herbicides was assessed: methyliodosulphuron natrium, sulphosulphuron and pyroxsulam (aceto-lactate synthase (ALS) inhibitors), fenoxaprop-P-ethyl and pinoxaden (acetyl-coenzyme A carboxylase (ACCase) inhibitors) and isoproturon (photosystem II (PSII) inhibitor). It was found that of the 159 seed samples tested, 43% showed little response to ALS inhibitors, sulphosulphuron, methyliodosulphuron and pyroxulam. Most of the tested populations were resistant to sulphosulphuron, while the fewest populations were resistant to pyroxulam, but all populations resistant to pyroxulam were resistant to both other ALS inhibitors, methyliodosulphuron natrium and sulphosulphuron. Growing resistance of A. spica-venti to ALS inhibitors will greatly restrict the choice of herbicides currently available for weed control in spring; therefore, autumn herbicide application in winter cereals in the future can become very important, especially in the fields, where A. spica-venti is highly distributed.

Weed infestations and associated yield losses require effective weed control measures in soybean and sugar beet. Besides chemical weed control, mechanical weeding plays an important role in integrated weed management systems. Field experiments were conducted at three locations for soybean in 2013 and 2014 and at four locations for sugar beet in 2014 to investigate if automatic steering technologies for inter-row weed hoeing using a camera or RTK-GNSS increase weed control efficacy, efficiency and crop yield. Treatments using precision farming technologies were compared with conventional weed control strategies. Weed densities in the experiments ranged from 15 to 154 plants m −2 with Chenopodium album, Polygonum convolvulus, Polygonum aviculare, Matricaria chamomilla and Lamium purpureum being the most abundant species. Weed hoeing using automatic steering technologies reduced weed densities in soybean by 89% and in sugar beet by 87% compared to 85% weed control efficacy in soybean and sugar beet with conventional weeding systems. Speed of weed hoeing could be increased from 4 km h −1 with conventional hoes to 7 and 10 km·h −1 , when automatic steering systems were used.Precision hoeing technologies increased soybean yield by 23% and sugar beet yield by 37%. After conventional hoeing and harrowing, soybean yields were increased by 28% and sugar beet yield by 26%. OPEN ACCESSAgronomy 2015, 5 131
