The H-Point Standard Addition Method (Hpsam)Has Been Applied For Simultaneous Determination of Maneb and Zineb Using1-(2-Pyridylazo)-2- Naphthol (Pan) As a Reagent. Both Maneb and Zineb Form Winered Colored Complex With Pan at Ph 9.2 Which Are Soluble In Triton X-100. Zineband Maneb Can Be Determined Simultaneously In the Range of 0.414-3.446 Μg Ml-1And 0.663-3.316 Μg Ml-1Respectively With Satisfactory Accuracy and Precision.The Proposed Method Has Successfully Been Applied For the Simultaneousdetermination of Maneb and Zineb In Several Synthetic Samples, Spiked Watersamples and Crops.
