Item description
IIL Anchor Metribuzin 70% WP Herbicide
Anchor from Insecticides (India) Ltd is a selective systemic herbicide containing Metribuzin 70% WP. It is registered for specified weeds in soybean, wheat, sugarcane, potato and tomato.
Metribuzin is absorbed through susceptible weed roots and leaves and inhibits photosynthesis. Whether Anchor is used before or after emergence depends on the crop-specific label directions; it is not a universal pre- or post-emergence treatment.
Important: The approved formulation rate, water volume, timing and pre-harvest interval differ by crop and, for wheat, by soil type. Do not derive one common grams-per-litre rate.
Why Choose Anchor?
- Selective systemic action: Metribuzin is taken up through roots and foliage of susceptible weeds.
- Registered mixed-weed spectrum: Crop-specific use tables include annual grasses, broadleaf weeds and certain sedges.
- Five registered crops: Approved formulation-level uses cover soybean, wheat, sugarcane, potato and tomato.
- Defined crop-specific rates: Separate directions help avoid unsafe blanket dosing.
- Resistance-planning clarity: HRAC Group 5 identification helps users choose genuinely different modes of action for later weed-control programs.

How Anchor Works
- Root and foliar uptake: Susceptible weeds absorb Metribuzin through their roots and leaves.
- Photosystem II inhibition: As an HRAC Group 5 herbicide, it interrupts photosynthetic electron transport at the D1 Serine-264 site.
- Loss of normal growth: Susceptible weeds can no longer maintain normal photosynthesis and decline after correct label-directed treatment.
Because Anchor relies on one Group 5 mode of action, avoid repeated sole reliance on Metribuzin. Combine crop rotation, physical weed control, field hygiene and label-approved herbicides from different HRAC groups in an integrated weed-management program.
Registered Crops, Weeds, Dose and PHI
| Crop / Timing | Registered Weed Scope | Formulation Rate | Water | PHI |
|---|---|---|---|---|
| Soybean | Digitaria spp., Cyperus esculentus, C. campestris, Borreria spp., Eragrostis spp. | 500–750 g/ha (about 202–304 g/acre) | 750–1,000 L/ha | 30 days |
| Wheat | Phalaris minor, Chenopodium album, Melilotus spp. | 250 g/ha on medium soil; 300 g/ha on heavy soil (about 101 g; 121 g/acre) | 500–750 L/ha | 120 days |
| Sugarcane – pre-emergence First workable spray condition or 3–5 DAP | Label-listed grasses, broadleaf weeds and sedges | 1.5–3 kg/ha (about 607–1,214 g/acre) | 750–1,000 L/ha | 60 days |
| Sugarcane – post-emergence 25–30 DAP | Registered grass, broadleaf and sedge spectrum | 1.5–2 kg/ha (about 607–809 g/acre) | 750–1,000 L/ha | 60 days |
| Potato 3–4 DAP pre-emergence, or after emergence before first plants reach 5 cm | Chenopodium album, Trianthema monogyna, Parthenium hysterophorus, Fumaria parviflora, Melilotus spp., Phalaris minor | 750 g/ha (about 304 g/acre) | 750–1,000 L/ha | 30 days |
| Tomato One week before transplanting, or 15 days after transplanting | Label-listed grasses and broadleaf weeds including Trianthema, Dactyloctenium, Amaranthus, Portulaca, Digera, Echinochloa, Ageratum, Eleusine, Setaria and Commelina | 750 g/ha (about 304 g/acre) | 750–1,000 L/ha | 30 days |
DAP = days after planting. PHI = Pre-Harvest Interval. Follow the current Anchor pack label; soybean and wheat timing is not generalized here because the approved-use table does not state it.
Application and Resistance Best Practices
- Match the crop row: Confirm the crop, weed spectrum, soil or timing condition, dose, water volume and PHI before measuring.
- Prepare correctly: Measure the wettable powder accurately and follow the current label for premixing and tank preparation.
- Coverage: Use calibrated equipment to create uniform label-directed coverage while avoiding overlap, drift and run-off.
- Do not improvise: Do not apply a blanket pre-emergence or post-emergence schedule across all five crops.
- Resistance management: Rotate with suitable label-approved herbicides from different HRAC groups and retain non-chemical weed control.
- No assumed tank mix: Any mixture must be expressly permitted by the current label or confirmed by a qualified agricultural specialist after checking the crop, stage, soil and compatibility.
Frequently Asked Questions
1. Which crops is Anchor registered for?
Soybean, wheat, sugarcane, potato and tomato under the approved-use table for Metribuzin 70% WP.
2. Can Anchor be used before and after weed emergence?
Only where the crop-specific label permits. Verified pre- and post-emergence timings are not identical across crops.
3. What is Anchor’s mode-of-action group?
Metribuzin is HRAC Group 5, a Photosystem II inhibitor.
4. Is there one grams-per-acre rate?
No. Rates differ greatly by crop and can also depend on soil or timing. Use the exact label row.
5. Can Anchor be tank-mixed?
Do not assume compatibility. Mix only when the current label or qualified crop-specific advice explicitly permits it. Recommended items shown on this page are standalone alternatives.
Safety and Disclaimer
Read the current label before opening the pack. Wear protective clothing, gloves, eye protection and an appropriate mask while measuring, mixing and spraying. Avoid skin, eye and inhalation exposure; do not eat, drink or smoke during use. Keep the product locked away from children, animals, food and feed. Follow the label for storage, disposal, first aid and re-entry. The toxicity colour is intentionally not stated because it was not verified for the current Anchor pack.
