Root grubs
Root grubs are the C-shaped larvae of scarab beetles that feed on plant roots, causing severe damage to turf, pastures, and crops by severing roots and leading to wilting and death. Common species include white grubs like those from the genera Phyllophaga (June beetles) and Popillia (Japanese beetles). Effective management combines cultural practices, biological controls, and targeted treatments for sustainable control.

root maggots
Root maggots are the larval stage of several fly species that target the roots and stems of cruciferous and onion-family crops, causing severe damage to seedlings and young plants. These pests thrive in cool, moist conditions and can lead to stunted growth, wilting, and complete crop loss if unmanaged. Effective identification, cultural controls, and organic treatments are key to protecting vulnerable crops like radishes, cabbage, and onions.
