Abstract
Significant reduction in shoot and root weight of pointed gourd (Trichosant hes dioica Roxb.) was observed at an initial inoculum density of 1 000 J(2) of Meloidogyne incognita per kg soil and hence was considered as the damag ing threshold level. The rate of nematode reproduction was density dependen t, the maximum being at the lowest inoculum density and the minimum at the highest density. Bare-root dip of 10-day-old rooted seedlings of pointed go urd in 0.05% concentration of carbosulfan 25 EC for 8 hr effectively reduce d nematode multiplication and root galling. Root dip in 0.1% carbosulfan fo r 6 hr exhibited lethal toxicity in seedlings.
