Abstract
Twenty new O,O-diaryl O-n-propyl phosphorothionates were tested in vitro for nematicidal activity against 2nd stage juveniles of Meloidogyne incognita. Out of these, eight which showed good activity were evaluated under glass-house conditions on sunflower. Three promising compounds were further evaluated on cowpea. These compounds have considerably increased the plant growth characters and significantly reduced the number of galls on the roots of sunflower and cowpea. O,O-Di (2,4,6-trichlorophenyl) O-n-propyl phosphorothionate and O,O-di (pentachlorophenyl) O-n-propyl phosphorothionate were found most promising against M. incognita showing better nematicidal activity than triazophos.
