“…At the same time, many European farmers and farmers' unions are vigorously opposed to the ban of glyphosate (Bjørnåvold et al, 2023). It is specially challenging for no-till agriculture because these systems can be difficult to set up and lack sustainable solutions for weed management without such type of herbicides (Kassam, 2019).…”

European farmers are required to follow the transition towards sustainable agriculture and food systems. Perennial weed management without chemical herbicides and inversion tillage is challenging farmers. Questions arise to cope with these spreading weeds. Our study focuses on farmers’ perceptions and experiences of perennial weeds and their control in Northern France and Eastern Germany. A survey was developed to explore the situation regarding present concerns and future problems for perennial weed control. The survey conducted from winter 2020/21 to spring 2021 targeted conventional, conservation and organic farms. We found a high level of awareness for perennial weeds. On average, 80.0% of Northern French farmers and 65.9% of Eastern German farmers revealed present concerns about perennial weeds. Both, Northern French and Eastern German farmers perceived perennial weeds are more damaging to crop production than other pests. In both regions, the farmers considered Cirsium arvense (L.) Scop. as the most important perennial weed. While the majority of the Eastern German farmers observed field infestations of Elymus repens (L.) Gould, Northern French farmers more often reported Sonchus arvensis L. infestations. More than 50% of the farmers stated Rumex spp. infestations in Northern France and Eastern Germany. Interestingly, Eastern German farmers are more concerned about future perennial weed problems than Northern French farmers. The reasons for farmer’s future concerns are probably connected to the farming system. In both regions, conservation and conventional farmers heavily rely on herbicides for perennial weed control, however, more farms used the active ingredient glyphosate in Eastern Germany. Nonetheless, perennial weed control is a major concern for organic farmers in both regions. We conclude that optimizing and integrating non-chemical alternatives is promising in all farming systems. Research activities are required to provide farmers and extension services with novel and profitable perennial weed management practices.

Glyphosate is the most widely used pesticide in Europe. However, due to its potential effects on human health, its renewal is currently under discussion in European policy. Here, we synthesize the existing evidence on potential farm-level economic impacts of a potential glyphosate ban in European agriculture using a literature review. We identified 19 studies published until 2022. We find that where glyphosate is currently used (30% and 50% of the acreage with annual and perennial tree crops respectively), such a ban can have large economic impacts. However, the range of impacts reported in the literature is substantial. Economic losses arising from a glyphosate ban estimated in peer reviewed studies range from 3 Euro/hectare in silage maize to up to 553 Euro/hectare in grapevine production. While potential losses are largest, in absolute terms (in Euro/hectare), for high-value perennial crops such as fruits and grapevines losses are similar in perennial and arable crops if expressed in relative terms (i.e. in % of per hectare profits). We currently lack assessments of economic implications of a glyphosate ban for most countries and farming systems. Thus, the overall economic implications at the European level are largely unknown.
