Abstract:The persistent toxicity of formothion and phorate on Brassica plants was investigated under field-cage conditionals by employing apterous adults of mustard aphid, Hyadaphis (Lipaphis) erysimi (Kaltenbach) Formothion (0.02 and 0.04% on foliage and 12 and 24 mg/pot in the soil) persisted for 18 days on both Brassica campestris and B. juncea. Seed treatment with formothion (0.08 and 0.16%) showed residual toxicity 14 days after sowing. The toxicity of the same doses of phorate was observed for 34 days in both soil and foliar treatments irrespective of doses and varieties, whereas in case of seed treatment the effect lasted 30 days after sowing.
