Preliminary studies on the population of phytonematodes with betlevine [piper betle] and their control by indigenous nematicide

ABSTRACT

Two nematicides viz. Furadan and Tenekil-M were tested for their efficacy against phytoparasitic nematodes i.e. Helicotylenchus indicus, H. digonicus, Hoplolaimus indicus, Rotylenchus reniformis and Longidorus siddiqui that are attacking betlevine. After 16 weeks of the experiments the number of these nematodes was reduced in treated plots than control. Tenekil-M was found to be a good nematicide. The nematicide is indigenous and economical for betlevine industry
