Characterisation of Czech arable weed communities according to management and production area considering the prevalence of herbicide-resistant species

Popis výsledku v původním jazyce

Herbicide resistance is a widespread issue that impacts management of conventional farms, but also has ramifications for the weed community assembly; it is therefore important to see how these species factor into the weed community assembly of farms throughout the countryside. This research analysed species richness and community diversity in 98 field relevés from 48 organic and 50 conventional farms evenly distributed between two major production regions of the Czech Republic and then evaluated the incidence of species which have been reported resistant in the Czech Republic and its neighbouring countries. Farms were selected independently of any acknowledged resistant species. Out of 164 species found in this survey, only eight species have had herbicide-resistant biotypes reported in the Czech Republic, while a total of 19 species had herbicide-resistant biotypes reported in neighbouring countries. Species with recorded resistance to PSII inhibitors in the Czech Republic tended to be found together and were mostly associated with the beet production region, characterised by low altitude: Amaranthus retroflexus, Chenopodium album, Echinochloa crus-galli and Solanum nigrum. Species with reported resistance to ALS and ACCase-inhibiting herbicides were not clearly associated with a particular region or farming type. Of the species which have had reported herbicide resistance in the neighbouring countries, several were found in conventional fields within the growing season and we recommend immediate screening for herbicide resistance in these species and more diligent action in management according to anti-resistance strategies: Bromus sterilis resistant to ACCase-inhibiting herbicides, A. retroflexus resistant to ALS-inhibiting herbicides or Avena fatua resistant to ACCase and ALS-inhibiting herbicides. This work is unique in that it is evaluating weed species diversity in organic and conventional farms and using the context to frame the prevalence of high-risk herbicide-resistant species; thereby putting the potential incidence of herbicide resistance into perspective at the landscape level.
