Insect Pestधान का तना छेदक (पीला तना छेदक)Parts: Stem
Yellow Stem Borer (Scirpophaga incertulas)
Affects: Paddy
Primary Chemical Cure
Cartap Hydrochloride 50% SP (Caldan) or Chlorantraniliprole 18.5% SC (Coragen)
300 gm Caldan 50 SP or 60 ml Coragen per acre.
Economic Threshold (ETL)
1 egg mass/m² or 5% dead hearts or 1 moth/m².
Initiate spray only when crossed
Bio & Organic Option
Release Trichogramma japonicum egg parasitoid @ 40,000/acre 3 times at weekly intervals.
Key Visual Diagnostic Symptoms
Inspect Stem in the field for these definitive physical manifestations:
- Dead-heart symptom in vegetative stage (central leaf whorl dries and pulls out easily).
- White-earhead symptom in reproductive stage (panicles turn completely white, chaffy, and erect with no grain filling).
Weather & Climate Factors Fueling Outbreaks
High humidity (>80%) and temperatures around 25°C-30°C.
Track real-time rain and humidity on our Aaj Ka Mausam Radar to preempt epidemics.
Preventive Agronomic & Cultural Controls
- Clip off rice seedling leaf tips prior to transplanting to eliminate egg masses.
- Install light traps to monitor adult moth flushes.

Frequently asked questions
The recommended chemical control is Cartap Hydrochloride 50% SP (Caldan) or Chlorantraniliprole 18.5% SC (Coragen), applied at 300 gm Caldan 50 SP or 60 ml Coragen per acre.. Ensure complete foliage coverage, spraying during early morning or evening hours.
1 egg mass/m² or 5% dead hearts or 1 moth/m².. Chemical sprays should only be initiated when the pest population or disease incidence crosses this threshold to avoid unnecessary spray costs and pesticide resistance.
Yes. Release Trichogramma japonicum egg parasitoid @ 40,000/acre 3 times at weekly intervals.. Combining biological controls with cultural practices like crop rotation and removing infected plant debris offers sustainable control without chemical residues.
Yellow Stem Borer (Scirpophaga incertulas) predominantly infects Paddy, attacking the Stem.
