Efficacy of Noval Nematicide on Root-knot Nematode, Meloidogyne javanica and Establishment of Recommended Dose in Mung Bean (Vigna radiata L.)

Abstract

The study was carried out to efficacy of newer nematicide (fluensulfone 2% GR) at different doses under field conditions on mung bean. Total seven treatments were used with different doses of fluensulfone 2% GR i.e., T1 - fluensulfone 2% GR 10 kg/ha., T2 - fluensulfone 2% GR 12 kg/ha., T3 - fluensulfone 2% GR 14 kg/ha., T4 - fluensulfone 2% GR 16 kg/ha., T5- fluensulfone 2% GR 18 kg/ha., T6- fluensulfone 2% GR 20 kg/ha., T7 - carbofuran 3G 50 kg/ha and T8 - untreated check (control) maintained for comparison. The observations were recorded on plant growth characters (shoot length (cm), shoot weight (gm), root length (cm), and root weight (gm)) and nematode reproduction (number of galls per plant, number of egg mass per plant, number of eggs per egg mass, nematode juveniles per 200 cc soil and final nematode population). Treated plant with fluensulfone 2% GR with the dose of 20kg/ha found to be the best to given the maximum plant growth characters and minimized nematode reproduction.
