Swiss public's acceptance and sustainability perceptions of food produced with chemical, digital and mechanical weed control measures and the influence of information source on technology perception in agriculture
<p><span>This data was obtained from an online survey conducted with the Swiss public from the two biggest language regions (German and French) in Switzerland. The survey was conducted in February 2023. Participants were recruited through a professional panel provider and quotas were used for age, gender and language region. The final sample contained </span><span>542 respondents. </span><span>In the first part of the survey, respondents provided basic sociodemographic information. In the second part, their sustainability perceptions regarding four different weed management practices (full-surface spraying, hoeing machine, spot spraying and precise spraying) were investigated. Respondents were then assigned to one of five information source groups, in which information on a hoeing and a milking robot was presented, using 5 different information sources (male/female farmer, male/female scientist, no source). Technology perception was assessed using several questions and aspects. Finally, respondents answered several questions assessing their attitudes towards the perception of farmers, food technology neophobia, chemophobia and the importance of naturalness. The survey can be used and adapted to different contents, aiming to investigate public perception of smart farming technologies and the influence of information sources on technology perception. </span></p>

Figure 4. Assessment of auxinic herbicides applied preemergence to suspected and confirmed 2,4-D–resistant Rophonus rophonistrum populations. Field-collected populations with suspected resistance to 2,4-D (11 populations) and the confirmed resistant,2,4-D–selected populations (populations R1–R11) were sprayed preemergence with 560 g ha−1 2,4- D, 570 g ha−1 MCPA, or 750 g ha−1 dicamba, and the field-collected populations were also sprayed postemergence as part of the same experiment (dark blue bars). Values are means ± SE (n = 11, with each population representing one replicate), and different letters above bars denote significant (P <0.05) differences between means. For visual comparison, the averaged data for populations R1–R11 sprayed postemergence with 500 g ha−1 2,4-D or dicamba or 600 g ha−1 MCPA were also included, along with the pre- and postemergence data for the pooled susceptible (S1 and S2) populations (light blue bars). Data for the postemergence 2,4-D and dicamba treatments of populations R1–R11 were taken from Goggin et al. (2018: supplementary table S3) and from the current glasshouse study for the postemergence MCPA treatment.

Figure 4. The effects of the pericarp (fruit coat) on the water uptake of (A) Lepidium drobo and (B) Lepidium oppelionum seeds.

N = 3 × 20 (fresh seeds) of accessions KM 1296 and KM 1754 (2014 to 2015 harvest); N = 3 × 10 for each time point measured (fresh seeds within pericarp).
