Why Choose This Product? Key Benefits
-
🎯  Crop-specific targeting: Separate cotton and chilli uses help match treatment to the pest present.
-
🔬  Two modes of action: Diafenthiuron and bifenthrin act at different biological targets, in IRAC Groups 12A and 3A.
-
🌿  Contact and stomach action: The combination acts on susceptible pests through contact and feeding.
-
💧  Suspension concentrate: Both active ingredients are supplied together for dilution and foliar spraying.

How It Works: Mode of Action
Bifentex combines two insecticide modes of action. Its contact and stomach activity is intended for the crop-specific pest uses below, not every insect or crop.
-
Diafenthiuron - Group 12A: Inhibits mitochondrial ATP synthase, disrupting energy production in susceptible pests.
-
Bifenthrin - Group 3A: Modulates sodium channels, disturbing normal nerve signalling in susceptible insects.
-
Targeted use: Match the identified pest and crop before spraying. A two-ingredient mixture is not a guarantee against resistance or pest return.
Changing brands alone does not change the mode of action. Account for both main IRAC Groups 12 and 3 when planning label-compliant rotation with a qualified crop adviser, alongside crop monitoring and suitable non-chemical practices.
Target Crops & Pests
Use each crop only for its paired target pests. The cotton whitefly use does not create a chilli whitefly recommendation.

Original rates are per hectare; acre values are approximate conversions. Calibrate the sprayer to deliver the stated product and water quantities over the measured area. The 500 ml bottle is a pack size, not a one-acre or one-tank dose.
Application timing: Apply during vegetative growth at pest incidence, initiating treatment when the pest population reaches the economic threshold level (ETL). Use crop-specific monitoring and local advice to assess that threshold; do not spray on a disease-severity schedule.
Harvest, re-entry and repeats: Allow 30 days from the final spray to cotton harvest and 7 days to chilli harvest. Follow the supplied label and authorised local guidance for worker re-entry and any repeat application. A harvest interval is not permission to re-enter, and a first-spray rate is not a repeat schedule.
How to Apply: Best Practices
-
Match the pack: Check Bifentex, its 47% + 9.4% SC formulation, crop and pest against the current label.
-
Shake and measure: Shake the bottle well. Measure the required quantity for the treatment area and mix thoroughly with the specified water volume.
-
Use the specified sprayer: Apply as a foliar spray with a knapsack sprayer fitted with a hollow-cone nozzle. Calibrate it for the measured area.
-
Avoid drift: Do not spray in windy conditions or against the wind. Keep spray away from yourself, other people, animals and water bodies.
-
Protect yourself: Wear the label-specified protective equipment when mixing and spraying. Avoid inhaling spray mist and wash after handling.
-
Check any proposed mixture: Use a tank mix or sticker only when the current labels and authorised crop-specific guidance permit the exact combination. Do not assume universal compatibility.
-
Observe waiting periods: Follow the crop-specific harvest interval and obtain the applicable re-entry and repeat-treatment directions before planning further work.
Frequently Asked Questions
Pack size does not define treatment area. Calculate the amount from the measured field and the labelled product rate, keeping the water volume matched to that area.
The crop-specific Bifentex directions list whitefly in cotton, but only thrips and aphids in chilli. Do not transfer the cotton claim to chilli.
It is an insecticide, not a fungicide. Assess the listed insect pests and the label-directed threshold rather than crop-disease severity.
Do not assume any mixture is suitable. Follow both current labels and authorised guidance for the exact combination; a jar test alone does not establish crop safety or label approval.
No. The 30-day cotton and 7-day chilli intervals concern harvest after the final spray. Worker re-entry and repeat treatment have separate directions and must not be inferred from those periods.
Safety & Disclaimer
Before you use it: Read and follow the current supplied label and leaflet. Confirm the crop, pest, product amount, water, method, timing, repeat limits and waiting periods. This overview does not replace the label or authorised agricultural advice.
The Bifentex safety data sheet warns that inhalation can be fatal. Avoid breathing spray mist and prevent skin and eye exposure. Wear the label-specified protective clothing, chemical-resistant gloves, boots, eye/face protection and respiratory protection. Do not eat, drink or smoke while handling; wash afterwards and clean contaminated clothing separately.
Very toxic to aquatic life with long-lasting effects. Do not use near aquaculture. Prevent spray, runoff, spills and washings from contaminating drains, ponds, streams or other water bodies. Keep children, animals and unprotected people away.
Store tightly closed in the original container in a cool, dry, ventilated and locked place away from food, feed, seeds and fertilisers. Never reuse empty containers; follow the label and local disposal requirements.
If exposure or illness occurs, seek urgent medical help and show the container, label or safety data sheet. Do not induce vomiting unless a doctor directs it, and never give anything by mouth to an unconscious person. Do not attempt home antidote treatment.
Read the AgroStar product page, Bifentex directions leaflet, safety data sheet and IRAC classification. Follow the supplied pack directions.
