Dissolved Organic Matter from Earthworm Casts Restrained the Phytotoxicity of Soil Glyphosate to Citrus (Poncirus trifoliata (L.) Raf.) Plants

A large amount of glyphosate enters the soil at a high frequency, forming “pseudo-persistent” pollutants that, in turn, threaten ecological function and crop growth. Earthworm casts (EWCs) are sound organic alternative to chemical fertilizers promote Dissolved matter from EWCs (EWC-DOM) is supposed be more mobile bioavailable fraction. However, effect EWC-DOM on phytotoxicity remains largely unknown. This study examines glyphosate-induced oxidative stress its impact antioxidant detoxification enzymes citrus plants grown soils with and/or without EWC-DOM. The results suggest that could reduce membrane lipid peroxidation level, thus slowing down aging order maintain stronger resilience, active (including SOD, POD, CAT) GST, laccase, CPR, UGTs) effectively remove reactive oxygen species (ROS) caused by stress, thereby alleviating damage ROS accumulation plant tissues. Our data indicate incorporating should way protect using for orchard weeding. has major implications sustainable healthy development production.
