Management Of Stemborer In Rice

Stemborer in Rice is one of the most common pests of paddy. Both male and female moths differ in size and have presence or absence of a black spot. The females are larger with a black spot which is absent in the smaller-sized male moths. They lay eggs that grow to become larvae and then pupa before they become adult moths.

Symptoms of Stemborer in Rice

The biggest symptom of Stemborer in Rice is the cluster of brown-colored eggs near the tip of the leaves. The larvae penetrate the central shoot resulting in drying of the shoot causing a ‘dead heart’. In an adult plant, the infestation causes drying of the panicle which is called ‘white ear’.  

Preventive Measures

  • Spraying neem seed kernel extract or neem oil are one of the effective preventive measures.  
  • Clipping the affected seedling tips should be done before the transplantation. This will remove the egg masses.  
  • The next should be using some quality insecticides.
