Item description
Rapigen GR Insecticide by AgroStar | 4
kg
A granular chlorantraniliprole insecticide for the specified
borers and leaf folder in rice and sugarcane. Apply as granules using the crop-specific placement and timing; it is not the
Rapigen SC spray formulation.
Formulation: Granules for the stated broadcasting or furrow/base
placement.
Rice timing: 15–35 days after transplanting.
Sugarcane timing: Match early-shoot-borer or top-borer timing separately, and
follow application with irrigation.
Why Choose This Product? Key Benefits
- 🌾 Rice pest programme: The leaflet pairs
rice yellow stem borer and leaf folder with a transplanting-based application window.
- 🎯 Target-specific sugarcane timing: Early
shoot borer and top borer have separate first-treatment triggers.
- 📦 Granular application: Use the specified
granule placement rather than inventing a spray dilution.
- 🛡️ Group 28 action: Chlorantraniliprole acts
on insect ryanodine receptors; resistance management still applies.

How It Works: Mode of Action
Chlorantraniliprole is an anthranilic diamide in IRAC Group 28:
ryanodine receptor modulators.
- Disrupts muscle function: Activation of insect ryanodine receptors releases stored calcium, affecting muscle control and
feeding.
- Keep resistance management separate: Rotate with effective insecticides from different IRAC groups under qualified advice. Changing
pack size or switching SC to GR does not change Group 28.
Target Crops & Pests
Use only the exact crop–pest pairs and application routes stated
in the current supplied leaflet.
| Crop | Target Pest(s) |
|---|---|
| Rice (paddy) | Yellow stem borer (Scirpophaga incertulas) and paddy leaf folder (Cnaphalocrocis medinalis). |
| Sugarcane | Early shoot borer (Chilo infuscatellus) and top borer (Scirpophaga excerptalis). |
Dosage & Application Guide
Formulated granule quantities for the crop–pest pairs above.
Broadcast uniformly; sugarcane requires the placement and irrigation directions below. The water field is not a spray dilution. PHI
means last treatment to harvest.
Dose per Acre & Original Label Basis
| Crop | Product per Acre | Water per Acre | Original Label Basis | PHI |
|---|---|---|---|---|
| Rice | Approx. 4.05 kg | Broadcast granules; no spray-water recipe | 10 kg/ha; leaflet prose also states 4 kg/acre | 53 days |
| Sugarcane | Approx. 7.59 kg | Granule placement followed by irrigation; no spray-water recipe | 18.75 kg/ha; leaflet prose also states 7.5 kg/acre | 147 days |
Rice first timing: Apply 15–35 days after transplanting for
the listed rice pests. Broadcast the granules uniformly using the crop programme.
Sugarcane first timing and placement: For early shoot
borer, apply between planting and the first irrigation. For top borer, time treatment with the appearance of top-borer moths. Place
granules in furrows at planting or at the base of young emerging shoots along the furrows, followed by irrigation. Do not substitute
the SC June programme.
Original units and rounding: The hectare table gives 10 and
18.75 kg/ha; leaflet prose gives rounded acre figures of 4 and 7.5 kg/acre. The approximate acre column is calculated from the hectare
figures × 0.40468564224 and rounded to two decimals. Keep the original label basis when calibrating.
Repeat and entry restrictions: No numerical repeat
interval, maximum count or worker re-entry interval is given in the leaflet. Obtain the current pack restrictions before any repeat or
re-entry; absence of a number is not unrestricted permission.
How to Apply: Best Practices
- Match the formulation: Use the 0.4% GR crop programme, not the 18.5% SC spray/drench programme. Weigh the formulated granules for
the actual treated area.
- Check the first-treatment trigger: Rice: 15–35 days after transplanting. Sugarcane early shoot borer: planting to first irrigation.
Sugarcane top borer: appearance of top-borer moths.
- Place granules as directed: Broadcast uniformly. For sugarcane, apply in furrows at planting or at the base of young emerging
shoots along furrows and follow with irrigation. Do not prepare a foliar tank mixture from these directions.
- Use protective equipment: Avoid dust generation and breathing dust; protect skin and eyes. Keep material and contaminated equipment
away from food, feed and water sources.
- Check partners and harvest: Confirm exact fungicide or other partner compatibility against both current labels. Record treatment
dates and observe 53 days PHI for rice or 147 days for sugarcane.
Frequently Asked Questions
No. GR contains 0.4% w/w chlorantraniliprole as granules; SC has a different concentration and application programme. Both remain IRAC Group 28, so switching formulations is not a mode-of-action rotation.
At 15–35 days after transplanting for the listed rice yellow stem borer and leaf folder programme. Broadcast uniformly and observe the 53-day harvest interval.
No. Early shoot borer: planting to first irrigation. Top borer: appearance of top-borer moths. Follow the stated furrow/base placement with irrigation and observe the 147-day PHI.
The leaflet gives rounded acre figures in its prose and 10/18.75 kg per hectare in its table. The approximate acre column is the mathematical conversion of that hectare table. Retain the supplied label’s original basis when measuring.
Do not turn the granule programme into a spray recipe or assume a pack treats a fixed area. Confirm current-label repeat, mixture and worker-entry restrictions before use; a generic incidence statement is not a fixed schedule.
Safety & Disclaimer
Before you use it: Read the current supplied pack label and leaflet. Match the crop, target,
formulation, route, first-treatment timing, product quantity, water or placement basis, harvest interval and worker-entry
restrictions. This overview does not replace the label or authenticate a batch.
Wear the label-specified protective clothing, gloves, goggles or face protection and required
respiratory protection. Avoid skin, eye and mouth contact and breathing dust or spray mist. Do not eat, drink or smoke during
handling. Wash exposed skin and contaminated clothing after work; keep children, animals and unprotected people
away.
Very toxic to aquatic life with long-lasting effects. Prevent drift, granules, spills, runoff and
washings from entering drains, ponds or watercourses. Store locked in the original tightly closed container in a cool, dry,
ventilated place away from food, feed, seeds and fertilizers. Do not reuse containers; follow current label and authorised
disposal requirements.
If exposure or illness occurs, stop work and seek medical advice with the container or label. Move away
from exposure, wash affected skin and rinse eyes with clean water. Do not induce vomiting unless a doctor directs it, give
anything by mouth to an unconscious person or attempt antidote treatment yourself. No specific antidote is stated; treatment
is for a clinician.
