Item description
Quiz Master Plus Herbicide by AgroStar | 500 ml
Quiz Master Plus is a selective post-emergence herbicide for the labelled grassy weeds in soybean. This listing is the 500 ml pack.
Active ingredient: Quizalofop-ethyl 10% w/w EC.
What it controls: The soybean grass-weed targets listed below, not every weed type.
When to use it: Post-emergence, 15–20 days after sowing soybean, with the required product, water and harvest interval.
Why Choose This Product? Key Benefits
- 🎯 Soybean grass-weed focus: Targets the listed love grass, crab grass, wild finger grass, viper grass, barnyard grass and browntop millet.
- 🍃 Systemic movement: The herbicide is absorbed through leaves and moves within susceptible weeds, supporting treatment beyond the leaf surface.
- 🌱 Post-emergence use: Applied after weeds emerge within the soybean application window, allowing the target grasses to be identified before treatment.
- 💧 Liquid EC formulation: The measured concentrate is emulsified in water for uniform application through the labelled spray equipment.

How It Works: Mode of Action
Quiz Master Plus combines selective post-emergence use with leaf uptake and movement within susceptible grasses.
- Identify emerged grass weeds: Match the weeds in the soybean field to the labelled targets. This is not a general pre-emergence soil treatment.
- Apply to foliage: Uniform spray contact allows the herbicide to enter through weed leaves and move within the plant.
- Keep use crop-specific: The programme below is for soybean. Selectivity does not make this product safe for every crop or effective against every broadleaf weed or sedge.
Field and weather conditions affect results; do not assume a fixed rainfast interval, a guaranteed weed-kill date or no regrowth.

Dosage & Application Guide
The following programme is for post-emergence foliar spraying on soybean with a knapsack sprayer fitted with a flat-fan nozzle. Product quantities refer to the formulated 10% EC herbicide, not pure active ingredient.
Dosage per Acre & Pre-Harvest Interval (PHI)
| Crop & Application Timing | Product / Acre | Water / Acre | Original Label Basis | PHI (Days) |
|---|---|---|---|---|
| Soybean 15–20 days after sowing | Approx. 152–182 ml | Approx. 121–202 L | 375–450 ml product + 300–500 L water / ha | 69–103 |
Acre quantities are approximate conversions of the original hectare rates, which remain in the table. One hectare is approximately 2.471 acres. Do not turn these figures into a universal per-litre or per-pump recipe, or treat the pack as fixed area coverage.
The leaflet states a harvest waiting period of 69–103 days after the last application. Before treatment, confirm the applicable interval on the current supplied pack or with the manufacturer; do not simply select the shortest value. PHI is a harvest interval, not a worker-entry interval.
AgroStar describes use when emerged weeds are at the 2–4-leaf stage. Keep the leaflet's soybean window of 15–20 days after sowing, and follow the supplied label for any further treatment, worker entry and planting a following crop. A dash in an interval field must not be treated as zero or unrestricted use.
How to Apply: Best Practices
- Match the exact formulation: Use Quiz Master Plus directions for quizalofop-ethyl 10% EC. Do not copy the crop list or rates from Quiz Master 5% EC or another herbicide.
- Check the crop and weeds: Use only on soybean for the listed grassy weeds. Do not extend the programme to other broadleaf crops merely because the herbicide is selective.
- Keep the application window: Apply 15–20 days after sowing soybean. AgroStar describes emerged weeds at the 2–4-leaf stage; confirm the crop and weed stage before treatment.
- Measure the area and quantities: Measure the liquid concentrate in millilitres and use the matching water volume for the measured area. Pack size is not a single-pump dose.
- Prepare the spray emulsion: Add the required herbicide slowly to water and stir well with a rod or stick until properly emulsified. Never mix with bare hands.
- Use the labelled equipment: Apply with a knapsack sprayer fitted with a flat-fan nozzle. Calibrate the sprayer for uniform coverage and the selected labelled product and water quantities.
- Prevent drift and water contamination: Do not spray against the wind. Keep spray drift and washings away from neighbouring crops, drains, ponds and streams. The leaflet warns that this product is moderately toxic to fish.
- Do not improvise mixtures or intervals: Use a tank partner only when the current label or manufacturer confirms the exact combination. Follow supplied-label restrictions for entry, repeat use, harvest and crop rotation; do not create an automatic repeat schedule.
