CAS 1861-32-1: Dacthal

Description: Dacthal, known chemically as dichloroacetic acid, is a selective herbicide primarily used for controlling broadleaf weeds and certain grasses in various crops. It is characterized by its low solubility in water and moderate volatility, which contributes to its effectiveness in soil applications. Dacthal acts by inhibiting the growth of target plants, disrupting their normal physiological processes. Its mode of action involves interference with cell division and elongation, leading to stunted growth. The substance is generally considered to have low toxicity to humans and animals, but it can pose risks to aquatic organisms, necessitating careful handling and application. Dacthal is often applied pre-emergence, meaning it is used before the target weeds germinate, making it an important tool in integrated pest management strategies. Regulatory assessments have led to specific guidelines regarding its use to minimize environmental impact while maximizing agricultural productivity. As with any chemical substance, adherence to safety protocols and regulations is essential to mitigate potential risks associated with its application.
