Cas no 34123-59-6 (Isoproturon)

Isoproturon is a selective systemic herbicide belonging to the phenylurea class, primarily used for pre- and post-emergence control of annual grasses and broadleaf weeds in cereal crops, such as wheat and barley. Its mode of action involves inhibition of photosynthesis by blocking electron transport at the photosystem II complex in chloroplasts. Isoproturon exhibits strong soil persistence and effective root uptake, ensuring prolonged weed control. It is particularly valued for its broad-spectrum activity against key weed species like blackgrass and wild oats, while maintaining crop selectivity. The compound's moderate water solubility and stability under typical agricultural conditions contribute to its reliable field performance. Formulated as wettable powders or suspension concentrates, it integrates well with standard application practices. Proper usage requires consideration of soil type and climatic conditions to optimize efficacy and minimize environmental impact.
