Insas Insecticide by Coromandel (Spiromesifen 22.9% SC)
The Ultimate Solution for Resistant Mites and Whiteflies
Struggling with mites and whiteflies that just won't die with regular sprays? Insas by Coromandel is your answer. It is a premium, high-tech acaricide (mite killer) and insecticide designed to target pests that have developed resistance to older chemicals.
Insas (Spiromesifen 22.9% SC) works differently than other poisons. It penetrates the leaf surface to reach hidden pests and breaks their lifecycle by targeting eggs and nymphs. Whether you are growing Cotton, Chilli, or Vegetables, Insas ensures your crop stays green, healthy, and high-yielding.

How It Works: Mode of Action
Insas acts as a Lipid Biosynthesis Inhibitor (LBI). In simple terms, it stops the pests from producing the essential fats and lipids they need to survive and grow.
[Image of Spiromesifen mode of action diagram]- Desiccation (Drying Out): By blocking fat production, Insas destroys the pest's waxy outer layer, causing them to lose water and dry out.
- Energy Starvation: Nymphs (young pests) cannot store energy for growth, leading to death.
- Reproductive Sterility: It makes adult female pests lay sterile eggs that never hatch, effectively crashing the population.
Note: It has Translaminar Action, meaning it penetrates the leaf to kill pests hiding on the underside.

Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 240 ml | 200 L | 1.2 ml | 10 Days |
| Chilli | 160 ml | 400 - 500 L | 0.4 ml | 7 Days |
| Brinjal / Tomato | 200 - 250 ml | 200 L | 1 - 1.2 ml | 3 - 5 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Spray at the "Early Instar" stage (when nymphs are young) for maximum kill. Do not wait for the population to explode.
- Mixing: Shake the bottle well before use. Add Insas to a little water, mix well, and then add to the main tank.
- Coverage: Ensure the undersides of leaves are sprayed, as mites and whiteflies hide there.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying during active bee foraging hours (mid-day).
Frequently Asked Questions
1. Does Insas kill adult mites?
Yes, it affects adults, but it is most powerful against eggs and nymphs. Adult females treated with Insas lay sterile eggs, effectively stopping the next generation.
2. Can I mix Insas with other pesticides?
Yes, Insas is compatible with most common insecticides and fungicides. However, do not mix it with highly alkaline substances like Bordeaux mixture.
3. How much Insas should I put in a 15-liter pump?
For most crops, use approximately 18 ml to 20 ml per 15-liter tank. Always check the acre dose first.
4. Is it safe for flowers and bees?
It is relatively safer than broad-spectrum poisons, but it is toxic to bees if sprayed directly on them. Apply in the evening when bees are not active.
5. Why is Insas better than older sprays?
Many mites have developed resistance to older chemicals. Insas uses a unique Mode of Action (Group 23) that works even on these resistant pests.
