Why Choose This Product? Key Benefits
-
⏱️
Stops Damage Instantly: Unlike other poisons that take time to kill, Dollar 50 SP paralyzes the pest's mouthparts immediately. The insect may live for a few hours, but it cannot eat your crop.
-
🛡️
Triple Action Protection: It works in three ways: Systemic (absorbed by the plant), Contact (hits the pest directly), and Stomach (poisonous when eaten).
-
⏳
Controls Resistant Pests: Excellent for controlling pests that have developed resistance to older chemicals like Organophosphates.
-
🌧️
Systemic Absorption: Once absorbed by the plant (requires 3-4 dry hours), the medicine spreads to new leaves and stems, killing hidden borers.
-
🌿
Broad Spectrum Use: Effective on a wide variety of chewing and sucking pests across multiple crop types.

How It Works: Mode of Action
Dollar 50 SP works differently than most poisons. It mimics a natural substance found in marine worms (Nereistoxin) to attack the insect's nervous system.
- Entry: The chemical enters the insect through contact (skin) or digestion (eating treated leaves).
- Nerve Block: It blocks the signals in the insect's nerves (specifically the nicotinic acetylcholine receptors).
- Starvation: The insect becomes paralyzed and cannot control its mouth. It stops feeding immediately and eventually dies of starvation.
Note: Because it leads to starvation, you might see the insect alive for a short time after spraying, but it is harmless to the crop.

Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Dollar 50 SP is a powder, so ensure it is fully dissolved in water.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Paddy (Rice) | 400 g | 200 - 400 L | 1 - 2 g/L | 15 - 21 Days |
| Vegetables | 400 g | 200 L | 2 g/L | 7 - 14 Days |
| Sugarcane | 400 - 600 g | 300 L | 1.5 - 2 g/L | Check Label |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Always confirm exact PHI on the product packet.
How to Apply: Best Practices
- Timing: Apply as soon as you see the first sign of damage (e.g., "Dead Hearts" in rice or folded leaves). For borers, early application is critical.
- Mixing: As a soluble powder (SP), it dissolves easily. Mix the required quantity in a small bucket of water first, then add to the main tank.
- Coverage: Ensure a fine mist covers both the upper and lower surfaces of the leaves for maximum absorption.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not use near fish ponds.
Frequently Asked Questions
1. Is Dollar 50 SP safe for fish?
No. This product is highly toxic to fish and aquatic life. Do not use it in paddy fields where you are also farming fish (Paddy-cum-fish culture).
2. Can I use it on Cotton or Apples?
Be very careful. Cartap Hydrochloride can cause damage (phytotoxicity) to sensitive crops like Cotton and Apples. It is best avoided on these unless specifically recommended by an expert.
3. What if it rains after spraying?
Dollar 50 SP needs about 3 to 4 hours of rain-free weather to be absorbed by the plant. If it rains immediately, the effectiveness will be reduced.
4. Can I mix it with other fungicides?
Yes, it is generally compatible with most common fungicides and insecticides. However, avoid mixing it with highly alkaline substances (like Bordeaux mixture) as it reduces efficacy.
5. How is this different from Granules (4G)?
Dollar 50 SP is a powder for spraying on leaves (Foliar), while Dollar 4G is a granule for broadcasting in the soil. 50 SP acts faster for standing crops with active pest attacks.
