Brinjal, also known as eggplant, is an important vegetable crop cultivated across India. However, brinjal shoot and fruit borer is one of the most damaging insect pests affecting brinjal cultivation. Its larvae bore into tender shoots and developing fruits, causing wilting, fruit damage, reduced market value and potential yield losses.
Effective brinjal pest management starts with regular crop monitoring, field sanitation and timely control measures. Farmers should also select suitable seeds based on their region, growing conditions and market requirements. At Mana GramaSethu, farmers can explore varieties such as Lalita F1 Brinjal Seeds, Simran F1 Hybrid Brinjal Seeds and Dhruva Brinjal Seeds. Farmers considering Ankur varieties can also review Vijay Brinjal Seeds.
What Is Brinjal Shoot and Fruit Borer?
Brinjal shoot and fruit borer is an insect pest scientifically known as Leucinodes orbonalis. Its larvae bore into tender shoots and developing fruits, feeding inside the plant tissue and making the affected parts unsuitable for normal growth or sale.
Because the larvae remain inside shoots and fruits, damage may become noticeable only after the infestation has progressed. Early identification and regular field inspections are therefore essential.The Tamil Nadu Agricultural University guide to brinjal pests provides information about pest identification and management, including the importance of recognising characteristic damage and removing affected plant parts.
Symptoms of Brinjal Shoot and Fruit Borer
Farmers should inspect brinjal plants regularly to identify fresh damage before the infestation spreads.
| Plant part | Symptoms |
|---|---|
| Tender shoots | Shoots wilt, droop or dry out. |
| Growing tips | Normal plant growth is affected, and shoots may stop developing. |
| Developing fruits | Small holes appear on the fruit surface. |
| Damaged fruits | Insect waste may be visible near the entry holes. |
| Flowers and buds | Flower buds may be damaged or drop prematurely. |
| Crop yield | Fruits become damaged and lose market value. |
One of the most recognisable symptoms is a wilted tender shoot or a developing fruit with a small entry hole. Farmers should remove affected shoots and fruits promptly and dispose of them appropriately rather than leaving them in the field.For additional guidance on identifying this pest and managing its damage, farmers can consult the TNAU brinjal pest management recommendations.
Why Does Brinjal Shoot and Fruit Borer Infestation Increase?
Brinjal shoot and fruit borer infestations can become difficult to manage when crop monitoring and sanitation are delayed. Larvae protected inside shoots and fruits are less exposed to treatments that act mainly on the plant surface.
Common factors that complicate pest management include:
-
Leaving infested shoots and fruits in the field.
-
Delayed identification of early symptoms.
-
Inadequate field sanitation.
-
Repeated use of insecticides with the same mode of action.
-
Applying treatments without confirming the pest.
-
Relying only on chemical control instead of integrated management.
How to Control Brinjal Shoot and Fruit Borer
1. Remove Infested Shoots and Fruits
Inspect the crop frequently, especially during active shoot growth and fruit development. Remove shoots showing borer damage and collect infested fruits before larvae can continue developing in them.Dispose of infested material according to local agricultural guidance. Do not leave it scattered around the field or place it near healthy crops.This sanitation practice is an important part of the management approach described in the Tamil Nadu Agricultural University brinjal pest guide.
2. Use Pheromone Traps for Monitoring
Suitable pheromone traps can help monitor adult moth activity and support decisions about when additional control measures may be needed. Use traps designed for the target pest and follow the manufacturer's instructions for placement, density and lure replacement.The Indian Institute of Horticultural Research biological-control technology overview describes integrated approaches involving pheromone traps and biological-control methods for managing brinjal shoot and fruit borer.Pheromone traps should be used as part of a broader pest-management programme rather than treated as a complete solution on their own.
3. Maintain Proper Field Sanitation
Remove infested plant material and manage volunteer brinjal plants that could harbour pests. Keep the field and surrounding crop area clean, and follow appropriate crop-residue management practices.Where practical, include suitable crop rotation and crop planning in the farm's management strategy. These measures can support pest management but may not eliminate an established infestation by themselves.
4. Encourage Biological Control
Beneficial organisms and suitable biological-control products can help reduce reliance on insecticides when incorporated into an appropriate integrated pest management programme.The IIHR biological-control overview discusses approaches involving Trichogramma chilonis, pheromone traps and Bacillus thuringiensis (Bt). Farmers should select suitable methods and follow local agricultural recommendations for their crop and pest conditions.
5. Monitor the Crop Regularly
Inspect tender shoots, growing tips and developing fruits for fresh damage. Record where symptoms appear and whether new damage is increasing. This helps farmers decide whether sanitation and monitoring are sufficient or whether an additional pest-control measure is necessary.
6. Use Suitable Insecticides When Required
If pest pressure warrants chemical control, select a suitable insecticide as part of an integrated pest management programme. The choice should depend on the target pest, active ingredient, mode of action and the product's approved use.Farmers can review products listed in the Mana GramaSethu insecticide collection to compare available options.
Insecticides for Brinjal Shoot and Fruit Borer Management
Effective brinjal shoot and fruit borer management combines timely pest control with regular field monitoring and good crop sanitation. The following products are options to explore based on their stated crop-pest uses.

Akhand Insecticide is listed at Mana GramaSethu as a combination formulation containing chlorantraniliprole, novaluron and emamectin benzoate. These active ingredients belong to different insecticide groups and act on insect development or nervous-system processes.The product listing identifies brinjal shoot and fruit borer as a target pest. Its combination of active ingredients makes the formulation relevant to a pest-management discussion, while its suitability depends on the approved use and the pest-management programme.
2. Bayer Camalus Insecticide
Bayer Camalus Insecticide combines tetraniliprole and spirotetramat. Bayer identifies brinjal and shoot and fruit borer among its recommended crop and pest uses.Tetraniliprole acts on insect ryanodine receptors, disrupting normal muscle function in susceptible insects. Spirotetramat affects lipid biosynthesis and is known for activity against certain sucking pests. The combination brings together different insecticidal actions, making it important to understand the product's specific target pests and directions.
3. Coragen Insecticide
Coragen Insecticide contains chlorantraniliprole 18.5% SC. This active ingredient acts on insect ryanodine receptors, disrupting normal muscle function and helping control susceptible insect larvae.Chlorantraniliprole is used against certain caterpillar pests, including brinjal fruit and shoot borer where the product is approved. It can form part of an integrated pest-management programme alongside field sanitation and pest monitoring.
How to Improve Insecticide Effectiveness
-
Apply at the right time: Monitor new shoot damage and developing fruits so pest activity can be identified early.
-
Combine control methods: Remove infested shoots and fruits, maintain field sanitation and use suitable pheromone traps.
-
Manage resistance: Rotate approved insecticides from different mode-of-action groups rather than repeatedly relying on the same active ingredient.
-
Protect beneficial insects: Avoid unnecessary spraying and follow integrated pest management practices.
-
Monitor results: Inspect the crop after treatment and use the observations to guide future management decisions.
Farmers can compare these products through the Mana GramaSethu insecticide collection. Selecting an appropriate product and combining it with preventive practices can help reduce crop damage and protect marketable brinjal fruits.
Why Is Insecticide Resistance Management Important?
Repeated use of insecticides with the same mode of action can select for resistant pest populations, making future treatments less effective. Farmers should avoid unnecessary applications and combine sanitation, monitoring, biological methods and appropriate chemical controls.
Research available through the Indian Council of Agricultural Research journal platform examines insecticide resistance-management strategies relevant to brinjal shoot and fruit borer.
For better resistance management:
-
Rotate approved insecticides according to their mode-of-action groups.
-
Avoid repeated applications of the same mode of action.
-
Combine chemical control with pest monitoring and removal of infested plant parts.
-
Follow integrated pest management recommendations.
-
Keep records of pest damage and treatments to support future decisions.
Can Fungicides Control Brinjal Shoot and Fruit Borer?
No. Brinjal shoot and fruit borer is an insect pest, so a fungicide is not the appropriate treatment for its larvae.Brinjal plants can also develop fungal diseases, but symptoms such as wilting or fruit damage should be identified correctly before choosing a crop-protection product. Different problems may require different management strategies.
When a fungal disease has been identified, farmers can review the Mana GramaSethu fungicide collection and explore products relevant to the diagnosed disease. Bacterial and viral diseases also require appropriate identification and management; they should not automatically be treated as fungal infections.
How to Reduce Brinjal Crop Losses
Integrated pest management combines preventive practices, field monitoring, biological methods and appropriate treatments when required.
Farmers can follow these practices:
-
Choose seed varieties suited to local growing conditions and market requirements.
-
Inspect shoots and fruits regularly.
-
Remove infested plant parts promptly.
-
Use suitable pheromone traps for monitoring.
-
Maintain good field sanitation.
-
Consider locally recommended biological-control methods.
-
Use suitable insecticides as part of an integrated programme.
-
Follow resistance-management recommendations.
Integrated approaches are also discussed in the ICAR-linked study on bio-intensive management of brinjal shoot and fruit borer. Such research can help farmers understand why combining management methods is often preferable to relying on a single control measure.Good irrigation, balanced nutrition and suitable crop care help maintain plant health, but these practices alone cannot prevent every pest infestation.
