The three species are noxious weeds introduced to Canada from southern North America. Their geographical distribution has remained almost unchanged since the original paper published in 1980. The plants exhibit a high phenotypic plasticity and genetic variability and they easily adapt to a multitude of agrestal and ruderal habitats. The seeds contribute to a persistent seed bank; they exhibit a variable dormancy and polymorph germination as a result of maternal, genetic and environmental factors. Growth is rapid and plants produce a large number of viable seeds. The three species have developed multiple resistance to triazine and acetolactate-synthase-inhibiting herbicides. They are alternate hosts to many insects, nematodes, viruses, bacteria and fungi that affect cultivated plants.

“…The height of the hedgerow can affect the spread of airborne diseases, depending on the dispersal height of the pathogen. 34 Our results in conidial dispersion showed that hedgerow height does not appear to affect the efficiency of the tested hedgerows (ranging between 4.7 and 9.0 m height). This might be linked to the aerologic properties of the pluricellular filamentous conidia that tend to fall more than fly, contrary to fusiform bicellular ascospores.…”

“…33 In future studies, it would be interesting to model how the disposition of hedgerows could improve the regulation of BLSD in a field to establish which hedgerow patterns would provide the best control. Such a modelling approach would certainly be useful to explore how hedgerows surrounding banana fields protect them from long distance dispersal 34 and how tree lines between banana plant rows, can protect them from field autocontamination as in agroforestry systems. 24,38…”

BACKGROUNDHedgerows represent an agroecological lever for pest management. To date, few studies have shown that they can be used as a lever for the control of aerial fungal diseases, especially as a barrier to dispersal. On banana production, the main disease is black leaf streak disease (BLSD), which is a fungal disease caused by Pseudocercospora fijiensis. This pathogen disperses through two types of spores: ascospore and conidia. The aim of this study was to observe and to quantify the effect of hedgerows on BLSD dispersal. Trap plants were placed at the same distance to an artificial source of inoculum with a hedgerow on one side. Lesions were counted to establish the daily lesion density of each trap plant. The combination of hedgerow characteristics such as height, width, and optical porosity were used to evaluate its potential capacity to intercept spores.RESULTSWhen ascospores were used as a source of inoculum, the lesion density on traps plant decreased up to 50% between the hedgerow with the lowest interception capacities and the one with the highest interception capacities. For conidia, hedgerow height and side of the trap plants (with or without hedgerow between them and the source) were not significant, but low porosity of the hedgerow reduced the lesion density. On the contrary, for ascospore, the hedgerow effect was anisotropic; the trap plants on hedgerow side had less lesions.CONCLUSIONOur study is the first experimental proof of the effect of hedgerows on P. fijiensis dispersion, both on conidia and ascospore. We showed that hedgerow characteristics impact the capacity of interception of the hedgerow. © 2023 Society of Chemical Industry.
