“…The great capacity of L. rigidum for developing resistance adapting to many different compounds has led to the development of multiple resistant populations in Australia (Powles, 1993) and to the existence of biotypes resistant to herbicides belonging to 10 different mode of action groups (Heap, 2005). Taking into account that climatic and edaphic conditions of some regions in Australia and Spain are similar, the herbicide resistance problem can potentially grow in Spain.…”

Lolium rigidum Gaud. is one of the most common weed species in winter cereals in Northeastern Spain. Herbicide resistance has been growing since the mid 90's and exclusive herbicide use is not enough in many cases, so that it is necessary to combine as many control tools as possible. Six field trials have been conducted during the cropping seasons 2001-02, 2002-03 and 2003-04 on winter cereal infested with herbicide resistant L. rigidum in Northeastern Spain testing different cultural control strategies. Sowing delay was conducted at five fields, mouldboard ploughing at four fields, the combination of sowing delay and ploughing at two fields, increasing the cereal sowing density and combined with sowing delay at one field. Sowing delay was confirmed to have an irregular efficacy depending on the L. rigidum emergence during the delay period. In the trials, weed emergence was reduced up to 88% in the best case but there was no effect in two cases. Ploughing had a more constant efficacy and reduced weed emergence between 50 and 80% although stoniness impeded in one occasion a correct soil inversion causing a very low efficacy. Increasing the cereal sowing rate did not reduce the weed population. The combination of the different methods did not increase significantly the individual efficacy, and one method was clearly more effective than the other, depending on the trial. In fields with high L. rigidum density, these methods are not effective enough and need to be combined with other methods, which are discussed in the text.Additional key words: cereal density, integrated weed management, mouldboard ploughing, sowing delay. ResumenControl cultural de poblaciones de Lolium rigidum Gaud. resistentes a herbicidas en cereal de invierno en el nordeste de EspañaLolium rigidum Gaud. es una de las especies de malas hierbas más comunes en cereal de invierno en el nordeste de España. La resistencia a herbicidas ha ido aumentando desde mediados de los años 90, haciendo necesaria la combinación de cuantas más técnicas de control sean posibles. Se realizaron seis ensayos de campo desde el año 2001 al 2004 sobre cereal de invierno infestado con L. rigidum resistente a diferentes herbicidas en el nordeste de España, para probar diferentes estrategias de control culturales. Se estudió el retraso de siembra en seis campos, laboreo de vertedera en cuatro campos, la combinación de retraso de siembra y laboreo de vertedera en dos campos, incrementar la densidad de siembra y combinarla con retraso de siembra en un campo. El retraso de siembra tuvo una eficacia irregular dependiendo de la emergencia de L. rigidum durante el período de retraso. Se alcanzó una reducción de la emergencia del 88% en el mejor de los casos, pero no hubo efecto en otros dos campos. El laboreo tuvo una eficacia más constante y redujo la emergencia de la mala hierba entre el 50 y el 80%, aunque la pedregosidad impidió en un caso una correcta labor. Incrementar la dosis de siembra no redujo la población de la mala hierba. La combinación de los diferentes ...

“…reduced herbicide uptake or translocation, increased herbicide sequestration, or enhanced herbicide metabolism). It is essential to understand that the accumulation of several resistance mechanisms within resistant individuals is now the normal situation for L. rigidum across vast areas of Australia (Powles and Matthews, 1992;Hall et al, 1994;Powles and Yu, 2010;Han et al, 2014a). Herbicide targetsite enzymes/molecules (Heap, 2014) and their genes are mostly well known, and target-site resistance is often documented in resistant weed populations (Tranel and Wright, 2002;Délye, 2005;Powles and Yu, 2010;Yu and Powles, 2014).…”

“…As target-site resistance is relatively easy to study, then, when identified, researchers often fail to examine for other coexisting resistance mechanisms. This is unfortunate, as the evolutionary reality is that any and all gene traits that can endow survival to an herbicide will be selected (Powles and Matthews, 1992). Insufficiently appreciated is that the intensity of the herbicide selection (herbicide rate used) is an important factor determining the resistance mechanism(s) selected, especially in genetically diverse, cross-pollinated species like L. rigidum.…”

Metabolism-Based Herbicide Resistance and Cross-Resistance in Crop Weeds: A Threat to Herbicide Sustainability and Global Crop Production

2014

Weedy plant species that have evolved resistance to herbicides due to enhanced metabolic capacity to detoxify herbicides (metabolic resistance) are a major issue. Metabolic herbicide resistance in weedy plant species first became evident in the 1980s in Australia (in Lolium rigidum) and the United Kingdom (in Alopecurus myosuroides) and is now increasingly recognized in several crop-weed species as a looming threat to herbicide sustainability and thus world crop production. Metabolic resistance often confers resistance to herbicides of different chemical groups and sites of action and can extend to new herbicide(s). Cytochrome P450 monooxygenase, glycosyl transferase, and glutathione S-transferase are often implicated in herbicide metabolic resistance. However, precise biochemical and molecular genetic elucidation of metabolic resistance had been stalled until recently. Complex cytochrome P450 superfamilies, high genetic diversity in metabolic resistant weedy plant species (especially cross-pollinated species), and the complexity of genetic control of metabolic resistance have all been barriers to advances in understanding metabolic herbicide resistance. However, next-generation sequencing technologies and transcriptome-wide gene expression profiling are now revealing the genes endowing metabolic herbicide resistance in plants. This Update presents an historical review to current understanding of metabolic herbicide resistance evolution in weedy plant species.

“…Thus far, the Asp-2078-Gly mutation in the plastidic ACCase enzyme is the only known mutation endowing clethodim resistance (Délye et al, 2005). As L. rigidum is a highly genetically variable species we expect that all possible herbicide resistanceendowing mechanisms can be present and enriched in large populations of this species under herbicide selection (Powles and Matthews, 1992). Thus, we expect that a number of different mutations endowing ACCase herbicide resistance (Table I) could be enriched both within and between different resistant populations.…”
