Further Studies on the control of the citrus nematode, Tylenchulus semipenetrans Cobb, 1913 infesting Citrus maxima Merrill

Five treatments, viz. sowing Tagetes in the basin, profos (Mocap 10 G) 40 kg, profos (Mocap) 20 L, DBCP (Nemagon) 20 L and fensulfothin (Dasanit 5 G) 30kg a.i./ha were tried for the control of citrus nematode, Tylenchulus semipenetrans Cobb infesting pummelo, Citrus maxima Merrill. DI CP 20 L and fensulfothion 30 kg a.i./ha were highly effective in controlling this nematode, the fruit yield increased by 74.6 and 67 percent (average of 2 years) respectively. Mocap 40 kg and 20 L ha, and sowing of T. erecta were rather ineffective.
