It's a systemic herbicide containing 45% Ametryn, a triazine-class active ingredient that works by inhibiting photosynthesis (PS II) in target weeds.
Commonly used to effectively control weeds in sugarcane, pineapple, and other agricultural areas, targeting problematic grass species like rumput kebau and rumput sambau.
Labeled for use in gardens, farms, factories, and similar areas—always read the label before use.
While explicit usage guidelines like dilution rates or timing weren’t found, here are generalized best practices based on typical Ametryn-based herbicide recommendations:
Follow the label exactly: The product label should guide mixing ratios, applications rates, intervals between applications, and other safety details.
Spot or broadcast application: Use a sprayer to apply either targeted sprays on weed patches or a blanket coverage depending on your situation (e.g., sugarcane field vs. home garden).
Target active weed areas: Make sure to spray directly onto weeds. As a systemic herbicide, it must be absorbed through leaves or roots to reach the growth zone.
Respect the concentration: A 45% active ingredient is relatively high—using the correct dilution is crucial, as using too much won’t necessarily increase effectiveness and could waste product or harm non-target plants.
Avoid drift: Apply when wind is minimal to prevent spray drift that could damage crops or nearby plants.
Protect water sources: Ametryn is soluble and can impact aquatic environments. Keep spray from running off into streams or ponds.
Toxicity to humans and animals: Ametryn is classified as slightly toxic (EPA Toxicity Class III). Exposure may cause nausea, vomiting, or skin/eye irritation.
Environmental fate: While Ametryn doesn’t leach heavily, it has the potential to reach groundwater—appropriate buffer zones are important.
Aquatic risk: Very sensitive aquatic plants (e.g., algae, duckweed) can be harmed by very low concentrations. A guideline for protecting most freshwater species is 0.10 µg/L (95% species protection).
| Feature | Details |

Check the product label for exact mixing instructions, application rates, pre-harvest intervals (if any), and safety guidelines.
Use protective gear—gloves, mask, goggles—to minimize exposure.
Apply with care, avoiding runoff or drift into sensitive areas (especially water bodies).
Consider environmental impacts—use the least amount necessary to achieve effective weed control.
