• Participants manage an apple farm in a multi-period business management game • Nudges improve compliance with the pre-harvest intervals after pesticide application • Response to the nudges of agricultural students is comparable to the response of the fruit growers Using an incentivized single-player, multi-period business management game in which the participants have to manage a virtual apple farm as an experimental device, this study examines how nudges can improve compliance with regard to the 14-day pre-harvest interval rule after the pesticide application. Two different samples are examined, namely German fruit growers and agricultural students. Two different green nudge treatments were investigated: a nudge with facts and pictures which imply environmental and health damages that are presumably caused by breaching the 14-day pre-harvest interval rule, and a nudge with an additional social comparison suggesting that the majority of fruit growers in the same region comply with the rule. The core result of the study is that nudging has a preventive effect and reduces participants non-compliance behavior in the business management game. The results are of interest to (agricultural) policy makers dealing with regulatory strategies in the context of pre-harvest intervals in apple production, as it is widely documented that nudging is an effective low-cost supplement to controls. Furthermore, the results are of interest for further research in the field of (experimental) economics and nudging, as we provide novel insights into the application of nudges.
