CAS 51218-45-2: Metolachlor

Description: Metolachlor is a selective herbicide primarily used for controlling annual grasses and certain broadleaf weeds in various crops, particularly corn and soybeans. It belongs to the chloroacetanilide class of herbicides and functions by inhibiting cell division in plants, effectively disrupting their growth. Metolachlor is typically applied pre-emergence or early post-emergence, allowing it to target weeds before they establish. The substance is characterized by its relatively low solubility in water, which contributes to its persistence in the soil, enhancing its effectiveness against weeds. It has a moderate toxicity profile for mammals, with specific safety measures recommended for handling and application. Metolachlor is also subject to environmental regulations due to its potential impact on non-target organisms and water sources. Its chemical structure includes a chloro group and an acetanilide moiety, which are critical for its herbicidal activity. Overall, Metolachlor is an important tool in agricultural weed management, but its use must be carefully managed to mitigate environmental risks.
