Product details
Slaytor Herbicide by AgroStar | 400 ml
Slaytor is a selective early post-emergence herbicide containing fomesafen 11.1% w/w + fluazifop-p-butyl 11.1% w/w SL. It controls the specified grassy and broadleaf weeds in soybean and groundnut when used at the labelled weed stage. This listing is the 400 ml pack.
What it controls: The separate soybean and groundnut weed lists below. A grass or broadleaf description does not mean every weed, crop or growth stage is covered.
When to use it: Apply once after sowing, early after weed emergence, when weeds have 2–5 leaves, are actively growing and soil moisture is suitable.
What to include: The measured product and spray water for the actual field area, a calibrated knapsack sprayer with a flat-fan nozzle and suitable protective equipment.
Why Choose This Product? Key Benefits
-
🌱 Early post-emergence use: Treats the listed weeds after they emerge, at the specified young weed stage rather than as a pre-emergence soil treatment.
-
🎯 Grassy and broadleaf targets: Combines two active ingredients for the separate weed sets listed for soybean and groundnut.
-
🧪 Two modes of action: Fomesafen and fluazifop-p-butyl act at different biochemical targets. This does not remove the need for resistance management.
-
🍃 Foliage-directed application: The labelled method uses thorough coverage of exposed weed foliage, supported by suitable soil moisture and active weed growth.

How It Works: Mode of Action
The two active ingredients work differently. Use the HRAC group numbers, not only the brand name, when planning weed-resistance management.
-
Fomesafen: Group 14: Inhibits protoporphyrinogen oxidase (PPO), disrupting a process involved in pigment formation and damaging susceptible weed tissue.
-
Fluazifop-p-butyl: Group 1: Inhibits acetyl-CoA carboxylase (ACCase), disrupting fatty-acid synthesis and the growth of susceptible grasses.
-
Correct stage and coverage: The programme depends on young, actively growing weeds and thorough exposure of their foliage to spray. Late treatment or missed foliage should not be corrected by increasing the rate.
The leaflet specifies one application. Do not make routine repeat sprays or rely continually on the same modes of action in the next crop season. Use integrated weed management and locally permitted alternatives with advice from a qualified agronomist.
Target Crops & Weeds
Keep each crop paired with its own weed list. These are the Slaytor leaflet’s soybean and groundnut uses, not a recommendation for other pulses, cereals or vegetables.

Dosage & Application Guide
Use the product-volume rates below only with the matching crop, weeds, early post-emergence timing, single-application limit and crop-specific harvest interval. Confirm the supplied pack label before measuring the product.

First application and number of applications: For both crops, apply once after sowing as an early post-emergence treatment at the 2–5-leaf stage of weeds, under optimum soil moisture conditions while weeds are actively growing. The leaf count refers to the weeds, not the crop.
Application method: Spray with a knapsack sprayer fitted with a flat-fan nozzle. Use the matching water volume and ensure thorough coverage of exposed weed foliage.
Harvest and worker entry: Allow at least 71 days after the soybean application or 82 days after the groundnut application before harvest. PHI is not a worker-entry interval; confirm worker-entry requirements on the supplied label separately.
Area-based measurement: Acre values are approximate conversions using 1 acre = 0.40468564224 hectare. Retain the original hectare rates for accurate area-based measurement. These are formulated-product volumes, not active-ingredient weights. No universal litre or tank recipe is supplied.
How to Apply: Best Practices
-
Identify the crop and weeds: Use only the crop and weed pairing listed above, after checking the supplied Slaytor label and current applicable restrictions.
-
Check the weed stage: Treat once at the 2–5-leaf weed stage after sowing, while weeds are actively growing and soil moisture is suitable. Do not substitute a fixed number of days after sowing or a pre-emergence treatment.
-
Measure and calibrate: Measure the treatment area and both product and water. Use the labelled knapsack/flat-fan method and even passes that wet weed foliage without missed strips or excessive overlap.
-
Keep mixing restrictions: AgroStar says not to mix Slaytor with fungicides or insecticides. Its general herbicide-compatibility statement is not approval for every partner; use an exact combination only when both product directions permit it.
-
Protect people and nearby areas: Avoid drift onto people, animals and non-target crops. Prevent spray, spills and washings from entering drains or water bodies. Do not use near aquaculture.
-
Clean and handle responsibly: Do not use kitchen utensils or bare hands to prepare spray. Wash contaminated clothing and clean equipment without contaminating water or food areas.
-
Keep the harvest interval: Use the crop’s own PHI and confirm worker-entry directions. Do not treat drying of the spray or the other crop’s interval as permission for early harvest or entry.
Frequently Asked Questions
No. Its labelled programmes are early post-emergence treatments on young, actively growing weeds. Do not apply it as a substitute for a before-weed-emergence soil treatment.
It refers to the weeds. Follow the weed stage together with suitable soil moisture, active weed growth and the single-application restriction. Late treatment can give incomplete control.
No. Soybean and groundnut have different harvest intervals. Keep each crop paired with its own complete programme; an equal product quantity does not make the waiting periods interchangeable.
No. AgroStar explicitly advises against mixing with either. Do not interpret broad herbicide-compatibility wording as permission for an unverified tank mix or adjuvant.
No. Pack size is a sale quantity, not a calibrated field or pump dose. The leaflet specifies one application; do not derive a pump recipe or add another application to compensate for late spraying or poor coverage.
Safety & Disclaimer
Before you use it: Read the supplied Slaytor label and leaflet, verify that they match this formulation, and follow current applicable restrictions. Keep crop, weeds, product quantity, water, method, first timing, number of applications and harvest interval together.
Wear protective clothing, chemical-resistant gloves, boots and eye or face protection; use the respiratory protection required for the handling task. Avoid contact with skin, eyes and mouth and avoid breathing spray mist. Do not eat, drink or smoke while handling. Wash hands and exposed skin and wash contaminated clothing before reuse.
The safety data sheet warns that the product is harmful if swallowed and is suspected of damaging the unborn child. Prevent exposure. If exposed or unwell, seek medical attention promptly and show the container, label or safety data sheet. Do not induce vomiting or give anything by mouth to an unconscious person. Move an inhalation casualty to fresh air, wash contaminated skin and rinse exposed eyes thoroughly with clean water.
Very toxic to aquatic life with long-lasting effects. Do not use near aquaculture. Keep spray, runoff, spills, equipment washings and empty packages out of drains, streams and other water bodies. Avoid drift onto non-target crops and surrounding areas.
Keep tightly closed in the original container in a cool, dry, well-ventilated, locked place, away from children, food, drink and animal feed. Do not reuse containers. Follow approved disposal routes and current local waste requirements rather than leaving packaging in the field. Results depend on correct timing, weeds, field conditions and application; no claim here guarantees crop safety or overrides the supplied label.
