Atabron - Chlorfluazuron 5.4% EC - UPL

UPL Atabron Chlorfluazuron 5.4% EC Insecticide

UPL Atabron is an insect growth regulator containing Chlorfluazuron 5.4% EC. It has contact and stomach action, translaminar movement and belongs to IRAC Group 15, the inhibitors of chitin biosynthesis affecting CHS1.

The current Indian label covers specified lepidopteran pests in cotton and cabbage. This Mana Agri Mart record is the fixed 500 ml pack. Use only for the crop, pest, dose, water volume, stage, re-entry period and PHI printed on the supplied label.

Key Reasons to Choose Atabron

• Insect growth regulation: Chlorfluazuron disrupts chitin formation and prevents susceptible larvae from completing a normal moult.
• Early-larval fit: UPL highlights early instar Spodoptera, Plutella and Helicoverpa/Heliothis as the most suitable target stage.
• Contact and stomach action: Target larvae are exposed through treated surfaces and feeding on treated foliage.
• Translaminar movement: UPL identifies movement through treated leaf tissue, while full and even spray coverage remains important.
• Clear official directions: The Government label supplies crop-specific formulation dose, water volume, re-entry, PHI and spray-frequency guidance.

Technical Specifications

How Atabron Works

Larvae need chitin to build a new cuticle during moulting. Chlorfluazuron interferes with chitin biosynthesis, so susceptible larvae cannot complete normal development. This is not the same as the rapid nerve action of a knockdown insecticide. Apply at the early larval stage identified on the label and allow the growth-regulator effect time to develop.

Atabron is an IRAC Group 15 product. Avoid treating successive pest generations only with Chlorfluazuron, Novaluron, Lufenuron or another Group 15 active. If a further treatment is needed, rotate to an effective product from a genuinely different IRAC group whose own current Indian label covers the same crop and pest. Rotation products are applied separately; no tank mix is implied.

Registered Crops, Pests and Dose

The Government label specifies application from the vegetative to reproductive stage and 2–3 sprays depending on infestation. These directions are not a routine spray calendar; scout the field and follow the current Atabron pack.

Mixing and Application Guide

1. Confirm the label use: Match cotton or cabbage, the target pest and the crop stage before opening the container.
2. Measure accurately: Calculate the formulation amount from the actual hectares treated and the applicable label row.
3. Premix: Measure the required quantity and mix it well with a small amount of clean water.
4. Complete the tank: Add the premix to the partly filled sprayer, add the remaining water while agitating and maintain a uniform emulsion.
5. Apply evenly: The label identifies knapsack, compression-knapsack and battery compression-knapsack sprayers. Obtain thorough crop coverage without excessive run-off or drift.
6. Observe intervals: Keep people and animals out for 24 hours and respect the crop PHI. Record every application.

Compatibility: Do not assume that Atabron can be mixed with another pesticide. Tank mixing requires explicit current-label support or qualified crop-specific advice.

Safety and Stewardship

• Read the complete label and leaflet and wear all required personal protective equipment while measuring, mixing, applying and cleaning equipment.
• Avoid inhaling spray mist or solvent vapour and prevent contact with the skin, eyes and mouth. Do not eat, drink or smoke during handling.
• Do not spray in strong wind or other unfavourable conditions. Use clean water and prevent drift to people, animals, adjacent crops and water.
• Prevent concentrate, spray liquid, rinsate and empty containers from entering wells, ponds, canals or drains.
• Store locked in the original labelled container away from children, animals, food, feed and seed. Never reuse the empty container.
• If exposure or illness occurs, follow the label first-aid directions, obtain urgent medical help and show the label or container.

Frequently Asked Questions

What does Atabron contain?
Atabron contains Chlorfluazuron 5.4% EC, a benzoylurea insect growth regulator in IRAC Group 15.

Which crops are on the reviewed Indian label?
Cotton and cabbage, for the specific lepidopteran pests listed in the table. Do not extend the recommendation to another crop or pest.

What is the waiting period?
The reviewed label states 10 days for cotton and 7 days for cabbage. Re-entry is 24 hours for both.

Does Atabron give instant knockdown?
It works mainly by disrupting chitin formation and moulting. Early-instar timing is more important than expecting immediate visible knockdown.

Can I mix Atabron with another insecticide?
No universal tank-mix recommendation is made. Related and Upsell products are standalone alternatives, not mixing partners.
