摘要：

Significant reduction in shoot and root weight of pointed gourd (Trichosanthes 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 damaging threshold level. The rate of nematode reproduction was density dependent, 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 gourd in 0.05% concentration of carbosulfan 25 EC for 8 hr effectively reduced nematode multiplication and root galling. Root dip in 0.1% carbosulfan for 6 hr exhibited lethal toxicity in seedlings.
