Affinity Herbicide | Carfentrazone-ethyl 40% DF
Affinity is a post-emergence contact herbicide for listed broadleaf weeds in wheat and direct-seeded rice, with sedge targets also listed for direct-seeded rice.
What it controls: Broadleaf weeds in wheat and direct-seeded rice, plus named Cyperus sedges in direct-seeded rice.
When to use it: Use on actively growing emerged weeds. The leaflet specifies wheat at 25–35 days after sowing after first irrigation, and direct-seeded rice at 10–15 days after sowing, at the 2–3-leaf broadleaf-weed stage.
What to include: Foliar spray with uniform weed coverage; protect adjacent broadleaf crops from drift.
Why Choose This Product? Key Benefits
- 🌿Post-emergence treatment: Treats weeds after emergence rather than acting as a pre-sowing treatment.
- 🎯Wheat broadleaf option: The wheat programme covers a named range of broadleaf weeds, including mallow and dock.
- 🌱Direct-seeded rice use: A distinct rice programme includes broadleaf weeds and Cyperus sedges.
- 🔬Contact action: Activity is directed at contacted weed tissue, so thorough and even coverage matters.
- 🛡️Clear grass-control distinction: Affinity is not a stand-alone answer to every grassy weed. Any grass-herbicide partner must be approved for the exact crop and mixture.

How It Works: Mode of Action
Affinity is a post-emergence contact herbicide for listed broadleaf weeds in wheat and direct-seeded rice, with sedge targets also listed for direct-seeded rice.
- Reach emerged weeds: The foliar treatment contacts the actively growing weed canopy.
- Disrupt cell protection: Carfentrazone-ethyl inhibits PPO, disturbing the processes that protect plant cells from light-related damage.
- Damage susceptible tissue: Affected cell membranes lose integrity and treated susceptible weeds deteriorate. Coverage and weed stage influence the outcome.
Use the mode-of-action group, not the brand name alone, when planning resistance management. Avoid repeated reliance on the same group.

How to Apply: Best Practices
- Application route: Foliar spray with uniform weed coverage; protect adjacent broadleaf crops from drift.
- Timing: Use on actively growing emerged weeds. The leaflet specifies wheat at 25–35 days after sowing after first irrigation, and direct-seeded rice at 10–15 days after sowing, at the 2–3-leaf broadleaf-weed stage.
- Coverage: Calibrate equipment and distribute the treatment evenly over the intended target. Avoid drift onto adjacent crops and water bodies.
- Mixing: Use only the mixtures and preparation directions allowed by the supplied label. A physical mixing test does not establish crop safety.
- After use: Clean application equipment safely, wash exposed skin and change contaminated clothing. Keep washings away from drains and surface water.
Frequently Asked Questions
What is Affinity Herbicide?Affinity is a post-emergence contact herbicide for listed broadleaf weeds in wheat and direct-seeded rice, with sedge targets also listed for direct-seeded rice.
Which crops and targets does it cover?Wheat and direct-seeded rice have separate programmes. The target table identifies their broadleaf weeds; the rice programme also includes Cyperus sedges.
Does Affinity control every grass weed?No. Its main role is broadleaf-weed control, with named sedges in direct-seeded rice. Do not assume that a grass-herbicide mixture is permitted without checking the exact partner and crop.
Can the dose be copied from another formulation?No. Match the exact formulation, crop, target and route. Product percentages, liquid volumes and granule weights cannot be substituted for one another.
What should be checked before application?Check the supplied label for product amount, water, timing, harvest and re-entry restrictions, protective equipment and any crop-specific precautions.
Safety & Disclaimer
Read and follow the supplied product label and accompanying leaflet. Use only for the stated crop, target and application conditions, and observe the applicable dose, waiting periods and precautions.
Avoid inhalation and contact with eyes and skin. Do not eat, drink or smoke during mixing or application. Store closed in its original container away from food, feed, heat and children.
