Active Ingredients – Details and Impact
MCPA (2-methyl-4-chlorophenoxyacetic acid):
- Purpose: Controls broadleaf weeds by mimicking natural plant hormones (auxins), disrupting growth
- Production: Synthesised via chlorination and esterification processes
- Environmental Impact: Linked to water contamination; caution required near aquatic habitats.
Pros: Highly effective on common weeds, minimal impact on grasses.
Cons: Persistent in soil, potential leaching into watercourses if over-applied.
Mecoprop-P:
- Purpose: Targets creeping and broadleaf weeds
- Production: Derived from phenoxyacetic acid compounds
- Environmental Impact: Moderate soil persistence; runoff risks require careful application
Pros: Effective against hard-to-control weeds like clover.
Cons: Overuse can harm beneficial plants; sensitive to drift.
Iron Sulphate (FeSO₄):
- Purpose: Kills moss, acidifies soil, and enhances grass colour
- Production: Created through the reaction of iron with sulphuric acid
- Environmental Impact: Generally safe if applied correctly; overuse can acidify soil excessively.
Pros: Rapid moss control and greening effect.
Cons: Can stain paving and surfaces; acidic properties may affect soil pH.
Best Use Cases and Cost Efficiency
