The above article, published online on 9 November 2023 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the journal's Editor-in-Chief Danielle Benoit; and John Wiley & Sons Ltd. The retraction has been agreed following an investigation of the concerns raised by Mycosphaerella arachidis on PubPeer [1], which identified unexpected similarities between multiple panels of Figure 7. More specifically, the images depicting the wounds of animals in the CSPUO and Control groups after 10 days appear identical to the image of the T4-W group after 15 days. Additional concerns have been identified regarding the similarity of the Day 0 and Day 5 panels of the CSPUO group to two panels in Figure 6A from another publication by the author group, where they are attributed to a different experimental condition [2]. As a result of the investigation, the data and conclusions of this article are considered unreliable. The authors disagree with this retraction.
