A roving survey was carried out in Namsai district of Arunachal Pradesh, India for prevalence of phytoplasma diseases and symptom presence. The phytoplasma infected plants were identified based on the symptomatology and confirmed by PCR analysis. The important crops grown in Namsai were surveyed and different crops exhibiting symptoms were observed and photographic evidence were collected for further studies. Symptoms of suspected phytoplasma infection was observed in potato (Solanum tuberosum), sesame (Sesamum indicum), garden pea (Pisum sativum), marigold (Tagetes spp.), hemp (Cannabis sativa) and henna plant (Lawsonia inermis).
