How to identify stem borer

Check the field for the following damage symptoms: Deadhearts or dead tillers that can be easily pulled from the base during the vegetative stages Whiteheads during reproductive stage where the emerging panicles are whitish and unfilled or empty Tiny holes on the stems and tillers Frass or fecal matters inside the damaged stems Deadhearts and whiteheads symptoms may sometimes be confused with damages caused by rats, neck blast, and black bug diseases. To confirm stem borer damage, visually inspect rice crop for deadhearts in the vegetative stages and whiteheads in reproductive stages. Stems can be pulled and dissected for larvae and pupae for confirmation of stem borer damage
