The present investigation was conducted to assess the investigation of root-knot nematode disease on bottle gourd in 10 area which were infected with Meloidogyne incognita. The highest frequency was found in Pathri village (90%)  followed by Pangri village and Balewadi village. The incidence was 80% in both the areas, the incidence was 70% and 60% in Alipur village and Mungashi and Babhulgaon village  respectively. The frequency in Gadegaon villages area was 50%. The lowest frequency 40% was found in Saundare and Khandavi villages.
The average both gall index and egg masses index is  ranged between 2-5 and 3 and 4. The largest eggmass and gall indicates 5 each was found in Pathri villages, the area where these incidence was most prevalent. The gall & eggmasses indices were 4 in Balewadi, Pangri & Alipur villages. In Babhulgaon , Mungashi, Surdi, and Gadegaon villages farm areas the indices were 3 each. The lowest incidences 2 each were noticed for Saundare and Khandavi villages. Thus the intensity of the disease on bottle gourd was highest in Pathri village closely followed by Pangri, Balewadi, Alipur, Babhulgaon, Mungashi, Gadegaon and Surdi villages farm area on the other hand, the incidence of the disease was relatively low in the fields of  Saundare and Khandavi villages.
Meloidogyne incognita were identified to infect bottle gourd in different areas. The many species were either found alone or in mixed population of M.incognita and M. javanica.
