CARVINT Insecticide by PI Industries: Composition, Benefits, Crops, Dose and Uses
CARVINT Insecticide
PI Industries has launched CARVINT, a new-generation insecticide developed to manage difficult insect pests such as thrips and diamondback moth in high-value vegetable crops. The product contains Flometoquin 10% SC, a comparatively new insecticidal chemistry with a different mode of action from many commonly used insecticides.
CARVINT is particularly relevant where farmers are experiencing reduced control from repeatedly used insecticides. Its rapid action, residual protection and different mode of action can make it a valuable component of an Integrated Pest Management (IPM) and insecticide-resistance management programme.
PI Industries launched CARVINT in India in September 2026, initially targeting important vegetable-growing markets such as Andhra Pradesh, Telangana, Karnataka, Tamil Nadu, Maharashtra, Gujarat and Madhya Pradesh. (global-agriculture.com)

CARVINT Chemical Composition
CARVINT contains:
Flometoquin 10% SC
This means that the active insecticidal ingredient is Flometoquin, supplied as a suspension concentrate formulation.
In an SC formulation, finely divided active-ingredient particles remain suspended in a water-based liquid. Before measuring the product, the bottle should therefore be shaken properly so that the active ingredient is distributed uniformly.
Flometoquin is classified under IRAC Group 34: Mitochondrial Complex III Electron Transport Inhibitors at the Qi site. The developer of Flometoquin describes it as an insecticide with rapid knockdown and residual activity against pests including thrips, whiteflies and diamondback moth. (NIPPON KAYAKU Co., Ltd.)
Important clarification: CARVINT is an insecticide. It controls insect pests, not fungal, bacterial or viral plant diseases.

How Does CARVINT Work?
Insects require a continuous supply of energy for movement, feeding, growth and survival. Flometoquin interferes with energy production inside the insect’s mitochondria.
More specifically, it inhibits electron transport at the Qi site of mitochondrial Complex III. As cellular energy production is disrupted, susceptible insects quickly become inactive, stop feeding and eventually die.
Scientific research has confirmed that Flometoquin acts as a mitochondrial Complex III Qi-site inhibitor and produces a rapid knockdown effect in susceptible insects. (jstage.jst.go.jp)
This distinct mechanism gives CARVINT an important place in rotation programmes, especially where growers have repeatedly used insecticides belonging to older mode-of-action groups.
Major Benefits of CARVINT Insecticide
1. Effective control of difficult thrips
Thrips are among the most troublesome pests of chilli. They scrape and suck sap from tender leaves, shoots, flowers and developing fruits.
A severe infestation can cause:
- Upward curling of leaves
- Crinkling and distortion
- Stunted plant growth
- Flower shedding
- Scarring or corkiness on fruits
- Lower marketable yield
CARVINT is registered for the management of thrips in chilli.
2. Control of diamondback moth
Diamondback moth is a destructive pest of cabbage and other cole crops. Its larvae feed on leaf tissue and may create characteristic window-like patches or holes.
Uncontrolled infestations can result in:
- Extensive leaf damage
- Reduced head development
- Contamination of cabbage heads
- Poor appearance and marketability
- Lower yield and quality
CARVINT provides a new mode of action for managing diamondback moth populations.
3. Rapid knockdown action
Flometoquin can act quickly on susceptible insects. Rapid feeding cessation is particularly important because crop damage may continue even before dead insects become visible.
4. Residual pest protection
In addition to quick action, Flometoquin is reported to provide residual activity. This may help protect treated foliage from subsequent pest activity for a period determined by infestation pressure, weather, crop growth and spray coverage.
5. New mode of action
CARVINT belongs to IRAC Group 34, which is different from commonly used neonicotinoids, pyrethroids, spinosyns, avermectins and diamides.
This makes it useful in a planned insecticide rotation. However, growers should not make repeated consecutive applications of CARVINT or another Group 34 product.
6. Useful for resistance management
Thrips and diamondback moth can develop resistance when the same insecticide or mode-of-action group is used continuously. Rotating CARVINT with effective insecticides from different IRAC groups can help delay resistance development.
7. Suitable for high-value vegetable crops
By protecting leaves, flowers and marketable plant parts from pest feeding, CARVINT can help maintain crop vigour, produce quality and marketable yield when used at the correct time and dose.
Recommended Crops, Target Pests and Dose
Published Indian recommendations for Flometoquin 10% SC list the following uses:
| Crop | Target insect pest | Active ingredient dose | Formulation dose | Water volume | Waiting period |
|---|---|---|---|---|---|
| Chilli | Thrips (Scirtothrips dorsalis) | 75–100 g/ha | 750–1,000 ml/ha | 500 L/ha | 10 days |
| Cabbage | Diamondback moth | 75–100 g/ha | 750–1,000 ml/ha | 500 L/ha | 10 days |
These crop, pest, water-volume and waiting-period recommendations are listed for Flometoquin 10% SC in an Indian agricultural pesticide reference. (jau.in)
Approximate dose per acre
Since one hectare equals approximately 2.47 acres:
- 750 ml per hectare ≈ 304 ml per acre
- 1,000 ml per hectare ≈ 405 ml per acre
- Water requirement: approximately 200 litres per acre
Therefore, the approximate field dose is:
CARVINT 300–405 ml per acre in about 200 litres of water.
Approximate dose per litre of water
When 750–1,000 ml is applied in 500 litres of water, the equivalent concentration is:
1.5–2 ml of CARVINT per litre of water.
Approximate knapsack-sprayer calculations:
| Sprayer capacity | Approximate CARVINT quantity |
|---|---|
| 10 litres | 15–20 ml |
| 15 litres | 22.5–30 ml |
| 16 litres | 24–32 ml |
| 20 litres | 30–40 ml |
These tank calculations are mathematical conversions of the hectare recommendation. Actual water volume and dose must follow the product label and local agricultural advice.
Is CARVINT Recommended for Cauliflower?
The launch announcement mentions use in vegetable crops including chilli, cabbage and cauliflower. (global-agriculture.com) However, the Indian crop-and-dose references reviewed specifically list chilli against thrips and cabbage against diamondback moth.
Therefore, CARVINT should be used on cauliflower only if cauliflower and its target pest appear on the current container label or leaflet sold in your state. Do not automatically transfer the cabbage dose to cauliflower without label confirmation.
Plant Diseases Controlled by CARVINT
CARVINT does not control plant diseases such as:
- Chilli anthracnose
- Powdery mildew
- Damping-off
- Phytophthora blight
- Alternaria leaf spot
- Cabbage black rot
- Downy mildew
- Clubroot
- Bacterial leaf spot
- Viral leaf-curl disease
A suitable registered fungicide, bactericide or disease-management programme is required for these problems.
CARVINT controls the insect pests specified on its label. Although thrips can sometimes contribute to the transmission of plant viruses, using an insecticide against the vector should not be presented as a cure for an already infected plant.
Best Time to Apply CARVINT
Apply CARVINT at the early stage of pest infestation, before the pest population reaches a severe level.
In chilli
Begin regular scouting after transplanting. Examine:
- Tender leaves and growing points
- Undersides of leaves
- Flower buds
- Open flowers
- Young fruits
Consider treatment when thrips are detected and their population reaches the locally recommended economic threshold.
In cabbage
Inspect the undersides of leaves for:
- Small diamondback moth larvae
- Feeding windows
- Irregular holes
- Larval droppings
- Small silken cocoons
Early-instar larvae are generally easier to manage than large, established populations.
How to Apply CARVINT
- Read the complete product label before use.
- Shake the CARVINT container thoroughly.
- Fill the spray tank halfway with clean water.
- Measure the required amount accurately.
- Prepare a small premix if directed by the label.
- Add the product to the spray tank while stirring.
- Add the remaining water and maintain agitation.
- Spray uniformly over the crop canopy.
- Ensure good coverage of tender leaves, growing points and leaf undersides.
- Avoid excessive runoff from the foliage.
Use a properly calibrated sprayer fitted with a suitable nozzle. Poor coverage can reduce control, particularly against thrips hiding in flowers, curled leaves and growing points.
Resistance-Management Guidelines
CARVINT should not be treated as the only solution for thrips or diamondback moth.
For responsible resistance management:
- Avoid repeated consecutive sprays of CARVINT.
- Do not rotate it with another product belonging to IRAC Group 34.
- Rotate with effective insecticides having different IRAC group numbers.
- Use the full label-recommended dose.
- Never reduce the dose simply to lower treatment costs.
- Spray at the early stage of infestation.
- Avoid unnecessary calendar-based spraying.
- Integrate cultural, mechanical and biological controls.
- Remove heavily infested or damaged crop material where practical.
- Control weeds that act as alternative pest hosts.
- Preserve natural enemies by avoiding indiscriminate insecticide applications.
Compatibility and Tank Mixing
Do not mix CARVINT with another pesticide, fertilizer, micronutrient or plant-growth regulator unless the combination is permitted on the product label or has been recommended by a qualified agricultural expert.
If an approved mixture is being considered:
- Check physical and chemical compatibility.
- Conduct a small jar test first.
- Avoid strongly acidic or alkaline mixtures unless permitted.
- Maintain continuous agitation.
- Never combine products merely to save labour.
Unnecessary tank mixtures may cause precipitation, nozzle blockage, crop injury or reduced pest control.
Safety Precautions
CARVINT is an agricultural insecticide and must be handled responsibly.
- Wear gloves, full-sleeved clothing, trousers, footwear, eye protection and an appropriate mask.
- Avoid inhaling spray mist.
- Do not eat, drink, smoke or chew tobacco while handling the product.
- Do not spray against the wind.
- Prevent contact with skin and eyes.
- Avoid drift onto neighbouring crops and water bodies.
- Keep children, animals and unprotected workers away from the treated field.
- Wash hands, face, clothing and equipment after spraying.
- Do not reuse empty pesticide containers.
- Dispose of empty containers according to label and local regulations.
- Store the product in its original container, away from food, feed and medicines.
If accidental exposure occurs, follow the first-aid directions printed on the label and seek medical assistance. Carry the container or label so the doctor can identify the active ingredient.
Pre-Harvest Interval
For the registered Flometoquin 10% SC uses reviewed, the reported pre-harvest interval is:
10 days for chilli and cabbage.
This means the crop should not be harvested for at least ten days after the last application, unless the current CARVINT label specifies otherwise. The APEDA-associated green-chilli pesticide list also records a formulation dose of 750–1,000 ml/ha and a ten-day pre-harvest interval. (apeda.gov.in)
