How It Works: Mode of Action
Johnny works on the insect's central nervous system. It is effective against pests that have developed resistance to older chemicals like organophosphates.
- Nerve Blockade: It blocks the "GABA" receptors in the insect's nerves. These receptors act as a brake for the nervous system.
- Over-Excitation: By removing the "brake," the insect's nerves fire uncontrollably. The pest suffers from severe tremors and convulsions.
- Paralysis & Death: The pest stops feeding quickly due to paralysis and dies shortly after. It works by both Contact (spray hitting the pest) and Ingestion (pest eating treated leaves).
It also moves slightly within the leaf (translaminar), reaching pests hiding on the underside.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Cotton | Thrips, Aphids, Jassids, Whitefly (Early Stage) |
| Chilli | Thrips, Aphids, Mites (Suppression) |
| Rice (Paddy) | Stem Borer, Leaf Folder |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Johnny is highly concentrated, so small doses are effective.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 180 - 200 ml | 200 L | 1.0 ml | 21 Days |
| Chilli | 180 - 200 ml | 200 L | 1.0 ml | 15 Days |
| Rice | 180 - 200 ml | 200 L | 1.0 ml | 30 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Best applied during the vegetative stage (25-45 days after sowing) to clear early sucking pests and boost root growth.
- Pollinator Safety (Critical): Do not spray when the crop is in full bloom (flowering). Fipronil is highly toxic to honeybees.
- Mixing: Shake the bottle well before use. Mix the 200ml dose in a small bucket first, then add to the main tank. It is compatible with most fungicides.
- Safety: Always wear a mask, gloves, and boots. Do not spray near fish ponds or aquaculture areas as it is toxic to fish.
Frequently Asked Questions
1. Why is Johnny more expensive than other generic brands?
Johnny is made with high-purity Gharda technicals. This superior quality ensures better suspension, no nozzle clogging, and a stronger "greening" effect on your crop compared to cheaper generics.
2. Does Johnny kill Bollworms?
It is primarily for sucking pests (Thrips, Jassids) but can suppress early-stage bollworm larvae. For heavy bollworm attacks, rotate with products like Emamectin or Indoxacarb.
3. Can I use Johnny on flowering cotton?
No. You should avoid spraying during peak flowering because it can kill honeybees, which are essential for pollination. Use it before flowering starts.
4. What is the difference between Johnny and Mahaveer (5% SC)?
Johnny is nearly 4 times more concentrated (18.87%) than Mahaveer (5%). This means you handle fewer bottles and get a more potent dose for tough, resistant pest populations.
5. Will it burn the leaves?
No. Johnny is a water-based Suspension Concentrate (SC), not an oil-based EC. It is very safe for the crop and does not cause leaf burn when used at the recommended dose.
