I am studying mollusk damage in soybean since 2017. Mollusk attacks were very rare then; however, they have become more frequent and destructive in recent years. Irreversible damage occurs when small seedlings are attacked, consequently soybean stand can be considerably reduced, and replanting is the only solution. Replanting brings about drawbacks such as harvest delay and economical losses. I developed management practices that include the damage caused by mollusks, scouting for them, and preventive use of molluscicides. A well-known farmer (who grows a large soybean acreage in western KY region) told me in 2021 “if with your recommendation I am expending $20/A, and making $12-14/bu, this is a profitable investment”. This farmer and some others in the central and western region kept controlling mollusk preventively in 2021 and in 2022. In 2021, we trained an undergraduate student from Murray State University on evaluation of predatory ground beetles, which is another component of the integrated mollusk management. Furthermore, as my applied field research in the UK-REC at Princeton continues we are now evaluating a set of different molluscicides in order to provide further alternatives to soybean farmers. This study is also helping with the management of an snail outbreak in soybeans.Check for morei information in the following link: https://kentuckypestnews.wordpress.com/2022/06/28/snail-outbreak-during-the-drought-and-hot-conditions-affect-soybeans/
