Emulsifiable concentrates of phosphamidon, oxydemeton-methyl, monocrotophos and carbosullan and seed dressinn gf carbosulfan and granules of phorate at recommended dosages were evaluated in a laboratory study against earthworm, Metaphire posthuma (Vaillant). Observations were recorded on survival of adults and emergence of juvenile earthworms on 7,14,30,60 and 90 d after the treatment. It was found that phosphamidon was relatively safer to juveniles than adult earthworms. Phorate granules and carbosulfan (EC as well as SO) were relatively safer to adults than juvenile earthworms. Oxydemeton-methyl and monocrotophos were toxic to both adults as well as juvenile earthworms.
Safety, , nsecticides, earrhworms, Metaphire posthuma.
