Terbucarb is a phenylcarbamate herbicide that disrupts the organization of microtubule centers in plant cells, leading to the formation of multipolar spindles and branched phragmoplasts, thereby inhibiting plant growth. It has been observed to induce an "anaphase star" image in onion root tips. Terbucarb exhibits cytotoxicity to isolated rat hepatocytes, causing cell death along with a loss of intracellular ATP, protein thiol, and glutathione.
