4576 Oryzalin Oryzalin is a pre-emergence surface-applied herbicide. It acts through the disruption (depolymerization) of microtubules, thus blocking anisotropic growth of plant cells. It is used for control of annual grasses and broad-leaved weeds in fruit trees, nut trees, vineyards, turfs and around ornamentals by selectively affecting physiological growth process. It can also be used to induce ploidity as an alternative to colchicine. It has a low aqueous solubility, is not volatile and, based on its chemical properties, is not expected to leach to groundwater. However, groundwater monitoring programmes have identified it as a pollutant. It generally tends not to be persistent in soil or water systems. It has a low mammalian toxicity and is a potential carcinogen. It is moderately toxic to birds, most aquatic organisms, honeybees and earthworms. 19044-88-3 29393 C12H18N4O6S White powder.
