“…For each year we estimated the area of organic orchard per farm by dividing the area of organic orchards in each district by the number of organic farms in that district. We then used this area to estimate the area of organic orchards at the municipality level taking into account the number (1 or 2) of organic farms (see also Etienne et al 2023). The results of this procedure which was evaluated on municipalities with more than three organic farms showed that on average the estimated areas under organic farming were aligned with the actual areas.…”

Context : The composition and configuration of habitats in agricultural landscapes may determine crop damage resulting from pests or pathogens either by directly affecting their population dynamics or through indirect effects on their natural enemies. Objectives The aim of this study was to assess the impact of landscape composition and configuration on the occurrence and damage caused by the codling moth and apple scab in apple orchards. Methods Using monitoring data at the French national scale, we examined how the proportion of landscape area grown with orchards the mean patch area of orchards the share of organic orchards and the proportion of woodlands and grasslands affected the occurrence and damage of these two pests from 2015 to 2019 in approximately sixty apple orchards each year. Results Landscapes with a higher proportion of orchards supported a higher occurrence of apple scab and earlier colonisation of codling moths. In addition, we found that codling moth damage decreased with increasing orchard patch area in the landscape. The proportion of seminatural habitats or organic farming in the landscape never significantly explained pest occurrence or damage. Conclusions Our results clearly highlight the importance of considering the amount and spatial arrangement of the pests’ and pathogens’ host crops to understand their infestation levels. Our study calls for the territorial management of orchard distribution to limit pesticide use in apple orchards.

“…Viticulture faces major challenges including the reduction of phytosanitary products (Etienne et al, 2023;Fouillet et al, 2023Fouillet et al, , 2022, adaptation to and mitigation of climate change (Naulleau et al, 2021;van Leeuwen et al, 2019), and the maintenance and improvement of soil quality (Coll et al, 2011;Salomé et al, 2016). Fungicides and herbicides, frequently used in viticulture (Fouillet et al, 2022;Jacquet et al, 2022;Urruty et al, 2016), are particularly under close watch due to increasing regulatory pressures from European countries, and source of public concern (Jacquet et al, 2022;Kudsk and Mathiassen, 2020;Lee et al, 2019).…”
