AI Overview
Chlortoluron is a stable, white needle-like phenylurea herbicide used for pre- and post-emergence weed control in cereals. It acts as a photosynthetic inhibitor, effective against grasses and broadleaf weeds. It is noted for high chemical stability to heat and relatively slow degradation in soil, with a half-life of 30–40 days.
Key Stability and Chemical Properties
- Stability: Stable at room temperature. It is resistant to heat, although it can undergo acid-base decomposition at high temperatures.
Application and Usage
- Usage: Used for controlling grass weeds and broadleaf weeds in wheat and barley crops.
- Formulation: Commonly used in mixtures, such as with diflufenican and pendimethalin (e.g., [Tower] herbicide).
- Application Rate: Modern formulations often use lower application rates, such as 250 g/ha, compared to older, higher rates.
Environmental and Safety Notes
- Mobility: It has moderate mobility in soil, which increases the risk of it reaching groundwater.
- Toxicity: It is considered low in toxicity to mammals but is generally toxic to birds, earthworms, and aquatic organisms.
- Degradation: Degrades in soil via microbial action and photolysis, producing metabolites like demethylated chlortoluron.
