What it controls: Rice: Yellow stem borer, Rice leaf folder
When to use it: Use the label’s 15–25-day post-transplant window, active tillering condition and stem-borer observation trigger.
What to include: Match the exact Chlorantraniliprole 5% w/w DT pack to its crop-specific instructions. Do not substitute another formulation or brand dose.
Why Choose This Product? Key Benefits
-
🌾Direct tablet application: The DT formulation is placed directly in the field. It is not a water-dispersible spray tablet.
-
🌱Two rice targets: The 2026 leaflet names yellow stem borer and rice leaf folder. This is more specific than a claim against all rice insects.
-
🎯Defined tillering window: The leaflet describes one application at 15–25 days after transplanting, during active tillering and when stem-borer adults or egg masses are visible.
-
💧Water-management instructions: The direct-application method includes standing-water requirements during and after placement, rather than a spray-water dilution.
-
🧪Clear harvest interval: The rice waiting period is 47 days from application to harvest, with a separate 24-hour re-entry restriction.

How It Works: Mode of Action
A direct-application tablet insecticide for yellow stem borer and rice leaf folder.
-
Field placement: The tablets are distributed uniformly in the rice field according to the labelled water and timing conditions.
-
Receptor action: Chlorantraniliprole disrupts calcium regulation at insect ryanodine receptors.
-
Feeding disruption: Normal muscle function is impaired in susceptible target insects, leading to feeding cessation, paralysis and death.
A mode-of-action group describes biological action, not a safety rating. A different brand containing the same active ingredient is not a different mode of action. Follow label limits and a locally appropriate resistance-management programme.

Dosage & Application Guide
Read product amount, water, application route and harvest interval as one crop-specific instruction. No per-tank quantity is inferred from tank capacity.
The label specifies 1,000–1,250 tablets per hectare for rice yellow stem borer and rice leaf folder. Measure by tablet count, not grams; do not calculate tablet numbers from an unverified tablet weight.
Apply once, uniformly in the field, at 15–25 days after transplanting during active tillering, coinciding with visible stem-borer adults or egg masses. Maintain 3–5 cm standing water at application, and keep standing water for at least 5–7 days afterward.
The 2026 leaflet specifies a 47-day rice PHI and 24-hour re-entry interval. It lists hand placement with chemical-resistant gloves or a mechanical dispenser; nozzle and mixing instructions are not applicable.
How to Apply: Best Practices
-
Check the rice stage: Use the label’s 15–25-day post-transplant window, active tillering condition and stem-borer observation trigger.
-
Count and place: Use the labelled tablet count per hectare. Distribute the tablets uniformly; do not improvise a grams-per-acre spray recipe.
-
Maintain water: Keep 3–5 cm standing water during placement and maintain standing water for at least 5–7 days afterward.
-
Protect operators: Use a mechanical dispenser or hand placement while wearing chemical-resistant gloves and all other prescribed protective clothing. Do not re-enter for 24 hours.
-
Protect the environment: The leaflet warns of high toxicity to fish and aquatic organisms and moderate toxicity to honey bees with long-lasting effects. Avoid use near aquaculture and during active bee foraging.
Frequently Asked Questions
1. Does DT mean I dissolve the tablets in a sprayer?
No. This label says tablets for direct application. It marks mixing and nozzle type as not applicable.
2. How is the tablet amount stated on the leaflet?
The label specifies 1,000–1,250 tablets per hectare. This is a tablet count, not a gram dose. No unverified tablet-weight conversion is supplied here.
3. How much standing water is needed?
The leaflet specifies 3–5 cm standing water at application and maintaining standing water for at least 5–7 days afterward. This is field water management, not a spray-tank dilution.
4. When can workers return and when can rice be harvested?
The cited leaflet restricts entry for 24 hours and gives a 47-day harvest interval. These are separate requirements.
5. Can I substitute a Coragen or Ferterra quantity?
No. Even though all contain chlorantraniliprole, their concentrations and formulation methods differ. Use the Resonex tablet-count instruction and its own label restrictions.
