Studies on the control of Meloidogyne graminicola on rice

Abstract

All root dip treatments, except mustard oil and gingelly oil resulted in significant reduction in adult females, egg-masses and galls (Table I). Significant increases in shoot height were associated with chemical pesticide treatments. Among the vegetable oils, only sunflower oil reduced galling and the number of adult females. There was an increase in shoot height and root length of seedlings in E. alba treatment (Tables I, II). All the soil drench treatments caused a significant reduction in egg-mass and gall numbers (Table II).
