%X The paper analyses the experimental results on the effects of various doses of Oleokalus insecticide (0.15, 0.75and 1.5 mg%), Oltisan herbicid (0.25, 1 and 2 mg%) and Tilt fungicide (0.25, 1 and 3 mg%) upon the isolated heart offrog (Rana ridibunda Pall.) perfused with a Ringer physiological solution. The doses, similar to those applied inagricultural practice, are considered as non-toxic for the environment (Baicu, 1979). The mechano-cardiogramsperformed showed that all pesticides under analysis cause depression in the cardiac activity of frog, its intensity andpersistence depending on the substance and dose applied. The maximum remanent cardio-inhibiting effects are inducedby fungicide Tilt.
