Nearly three fourth of the farmers considered spotted pod borer as a major pest of yarldlong bean in Chitwan. Most of them considered more than 60% loss caused by spotted pod borer if no management practice is applied. Almost all sprayed chemical pesticides for management of spotted pod borer and nearly three fourth of them used more than one chemical pesticides alternately for management of spotted pod borer.One third farmers (31.43%) applied chemical pesticides in 4-7 days interval and one third of them (31.43%) applied chemical pesticides in 7-10 days interval after beginning of flowering for management of spotted pod borer.
