Tuta Absoluta is one of the most destructive pests in tomato farming. If not controlled early, it can destroy up to 80–100% of the crop. Every tomato farmer must know how to identify it early and control it effectively.
What is Tuta Absoluta?
Tuta absoluta is a small moth whose larvae (caterpillars) attack tomato plants. It is also known as the tomato leaf miner because it makes tunnels (mines) inside leaves, stems, and fruits.
Stages of Tuta Absoluta
Tuta has four main life stages:
1. Egg Stage
- The adult moth lays tiny eggs on leaves, stems, or under leaves.
- Eggs hatch within 4–6 days.
2. Larva (Caterpillar) Stage – Most Destructive Stage
- The small caterpillar enters inside leaves, stems, or fruits.
- It feeds while hidden inside the plant tissue.
- This stage lasts about 10–15 days.
- It causes the most damage.
3. Pupa Stage
- The larva pupates in soil, on leaves, or inside plant parts.
- This stage lasts about 7–10 days.
4. Adult Moth Stage
- A small grey moth emerges.
- It flies mostly at night and lays more eggs.
- The cycle repeats quickly.
Because the life cycle is short, the pest multiplies very fast.
How Tuta Absoluta Damages Tomatoes
Tuta can attack tomatoes from nursery to harvest.
Leaf Damage
- Irregular white or brown tunnels inside leaves.
- Leaves dry and die.
Stem Damage
- Tunnels inside stems weaken the plant.
Fruit Damage
- Small holes on fruits.
- Fruits rot and become unmarketable.
Damaged fruits cannot be sold, leading to major losses.
Agronomic Practices to Reduce Tuta Infestation
Good farm management helps reduce Tuta pressure.
✔ Use Clean Seedlings
Start with healthy, pest-free seedlings.
✔ Field Hygiene
- Remove and destroy infested leaves and fruits.
- Clear crop residues after harvest.
✔ Crop Rotation
Avoid planting tomatoes continuously in the same field.
✔ Regular Scouting
- Inspect plants at least twice a week.
- Check under leaves for eggs and mines.
- Early detection makes control easier.
✔ Use Traps
Pheromone traps help monitor moth activity.
Best Active Ingredients to Control Tuta Absoluta
Two highly effective active ingredients against Tuta are:
1. Chlorfenapyr
- Works by disrupting the pest’s energy production.
- Kills larvae effectively.
- Controls hidden stages inside leaves.
2. Emamectin Benzoate
- Attacks the pest’s nervous system.
- Stops feeding quickly.
- Highly effective against caterpillars.
Why Combine Them?
When Chlorfenapyr and Emamectin Benzoate are combined:
✔ They control eggs, larvae, and adult stages
✔ Provide fast knockdown and long-lasting protection
✔ Reduce resistance development
✔ Improve marketable tomato yield
Recommended Solution: Fenari 120SC
Farmers are encouraged to use Fenari 120SC.

How to Apply
For best results:
- Spray immediately when the first signs appear.
- Ensure thorough coverage of leaves (especially under leaves).
- Spray in the early morning or late evening.
- Follow label instructions for safety and dosage.
Early spraying prevents heavy infestation.
Do not wait until fruits are damaged. Scout your crop regularly. Combine good farm practices with effective insecticides. Use trusted products like Fenari 120SC for reliable and effective control. Early control means healthy tomatoes and higher profits.
