Target weeds: Selected grasses, sedges and broadleaf weeds, with a different weed
list for each crop.

Crop fit: For groundnut and soybean; match the weeds to the correct crop row
below.

How It Works: Mode of Action
Vostrix disrupts two processes that susceptible weeds need for new
growth.
-
Metamifop: Inhibits acetyl-CoA carboxylase (ACCase), disrupting production of essential fatty acids needed for weed growth.
-
Imazethapyr: Inhibits acetolactate synthase (ALS), blocking production of essential amino acids needed for weed growth.
-
Imazamox: Inhibits acetolactate synthase (ALS), interrupting the same amino-acid production process as imazethapyr.
Metamifop belongs to HRAC Group 1; imazethapyr and imazamox both belong to Group 2. Three active ingredients
therefore provide two modes of action, not three. Consider both groups when choosing a different mode of action for future treatments.
The mixture does not guarantee resistance prevention or control of every weed; follow the crop-specific target lists and current-label
restrictions.

Identify the weeds before choosing a treatment. The two crop lists
are not interchangeable, and the product is not an all-weed treatment.

Keep the product, required ammonium sulphate and water quantities on the same acre basis. Follow the supplied
pack’s full mixing instructions, including additive incorporation order; do not substitute an additive or infer a per-litre or tank
recipe. Observe the crop-specific harvest interval after the last treatment and check re-entry restrictions
separately.
Use after the target weeds emerge and reach the 2–4-leaf stage.
Check the crop's suitability and all crop-stage restrictions before treatment.
-
Application route: Use a knapsack sprayer with a flat-fan or flood-jet nozzle.
-
Mixing: Mix the product initially with a small quantity of water, then add the remaining water with thorough agitation. Use only
the additive and incorporation order specified for the supplied pack.
How to Apply: Best Practices
-
Check the field: Confirm the crop, weed identity and weed leaf stage before spraying. This is not a pre-emergence treatment.
-
Calibrate the sprayer: Match the product, additive and water quantities to the same measured field area. Tank capacity alone does
not establish coverage.
-
Keep mixtures specific: Do not treat the premix as permission to add another herbicide or substitute the required additive. Use a
mixture only when both current labels permit the proposed combination for the crop and use.
-
Protect nearby areas: Prevent spray drift and contamination of water, neighbouring crops and non-target plants.
-
Plan following crops: Check the supplied label's rotational-crop, repeat-application and re-entry restrictions before planning
subsequent field work.
Frequently Asked Questions
1. Which crops is Vostrix for?
Groundnut and soybean, with the separate target-weed lists shown above.
2. Can it be used before weeds emerge?
No. Its use is after weed emergence at the 2–4-leaf weed stage.
3. Does it control every weed in those crops?
No. Match the weed species to the correct crop row. Similar-looking weeds should not be assumed to respond
the same way.
4. Do three ingredients mean three modes of action?
No. Metamifop is in HRAC Group 1; imazethapyr and imazamox are both in Group 2.
5. Can I choose an additive or spray-pump dose myself?
Use the required ammonium sulphate with the complete crop-specific product and water quantities. Follow the
supplied label’s additive incorporation order and mixing instructions. Do not substitute an additive or infer a dose from tank
capacity.
Safety & Disclaimer
Before you use it: Read and follow the supplied Vostrix label and leaflet for the crop, target weeds,
product and additive quantities, protective equipment, harvest interval, re-entry and disposal requirements. Do not use an
unlisted crop, mixture or repeat schedule.
After the last treatment, wait at least 83 days before harvesting groundnut or 56 days before
harvesting soybean. These are crop-specific harvest intervals, not worker re-entry times.
Wear the protective equipment specified on the pack. Do not mix with bare hands. Avoid skin, eye and mouth
contact and inhaling spray mist, fog or vapour. Do not eat, drink, smoke or chew while handling or spraying; wash thoroughly
afterwards. Follow the pack’s weather precautions.
Keep away from children, animals, food and animal feed. Store in the original labelled container away from
water and fire. Prevent drift and contamination of water sources, and follow the pack’s first-aid, equipment-cleaning and disposal
instructions. Never reuse pesticide containers. Seek medical help after exposure or illness and take the pack or
label.
