Determination of extent of survival of Aphelenchoides besseyi in prosomillet

Abstract

Foliar nematode, Aphelenchoides besseyi is of great concern for profitable cultivation of prosomillet
(Panicum miliaceum). Attempts were made for the studies on population dynamics and comparative
survival of Aphelenchoides besseyi in different germplasm of prosomillet from Tamilnadu and Madhya
Pradesh to be the first kind of its own study. The Present investigation included nine germplasm of
prosomillet namely -TNAU-137, TNAU-145, TNAU-149, TNAU-151, TNAU-155, TNAU- 164, TNAU-
183, TNAU-191 and TNAU- 194 and some MP. The germplasm were stored for the period of
consecutive four years and investigated their population dynamics and survival in field and
laboratory of Plant Pathology during 2014-15.
