Plant protection practices: how do risk perception, subjective and objective knowledge influence the preference of German consumers

Abstract

PurposeThe purpose of this paper is to identify which plant protection practices consumers prefer and why. The authors focused on beneficial insects, genetically modified (GM) plants, synthetic chemical pesticides, biological plant protection, mechanical-physical plant protection as well as biotechnical plant protection. The authors studied the effects of the risk perception and both subjective and objective knowledge on preference.Design/methodology/approachThe authors collected cross-sectional data from n = 1,223 people living in Germany. For this, the authors used an online panel and quoted participation after age, gender, income and region. The authors used multiple regression analyses and also explored moderation effects of knowledge on risk perception to explain participants' preferences.FindingsThe most preferred plant protection practice in the study sample was the application of beneficial insects. The authors found evidence that risk perception, as well as objective and subjective knowledge, can have a pivotal direct effect on preferences. Additionally, subjective as well as objective knowledge typically moderated the effect of risk perception, depending on the plant protection practice in focus. Overall, the authors found that levels of subjective and objective knowledge of plant protection practices were rather low among German participants.Originality/valueWhile studies on consumer preferences for GM or organic food are abundant, preferences regarding other types of common plant protection practices are hardly investigated. To tackle this research gap, the authors focused on six different and common plant protection practices and compare results.

The Impact of Risk Perception Difference of Members of a Scientific Research Project Team on Information Adoption: The Moderating Effect of Knowledge Inertia

“…This once again showed that individual psychological factors are the key link connecting their cognition and behavior [63,64]. Meanwhile, it also further revealed the internal influence process of risk perception difference on behavior [35][36][37]. That is, the differentiated perceptions can positively stimulate the subject's learning willingness, and then promote the formation of information adoption behavior, which deepens the current research on the effect of risk perception difference.…”

“…From the perspective of the risk management process, it is manifested as cognitive differences in risk sources, probability of occurrence, degree of impact, and confidence in dealing with it. As a cognitive element, risk perception is the result of an individual's judgment on the connotation and value of risk information and can further affect an individual's behavior and preferences [35][36][37]. On the other hand, information adoption is a process in which the subject selects, evaluates, accepts, and utilizes information purposefully [38].…”

“…Objective knowledge is stored in the consumers’ long-term memory and is usually assessed through testing [ 48 , 49 ]. In contrast, subjective knowledge is based on direct experience by consumers and their interpretation of these experiences [ 43 ].…”

“…For instance, organic versus conventional agricultural management practices (Cristache et al 2018, Gomiero, 2012). • Some food cultures are more likely to rely on traditional methods of preserving or preparing food, which can increase the risk of pests and diseases (Lehberger and Becker, 2020). For instance, the use of some types of fermentation using soy sauce and miso (Skowron et al, 2022).…”
