Persistence of hexaconazole and triazophos residues on spinach leaves
Journal Title: Bioscience Discovery - Year 2017, Vol 8, Issue 1
Abstract
Application of pesticides as foliar spray has become common practice in modern agriculture. Hexaconazole and Triazophos are pesticides from triazole groups commonly used for control of fungal diseases and insect pest respectively in vegetable crops. In the present work, plants were sprayed with Hexaconazole and Triazophos at various concentrations (0.05, 0.10, 0.15, 0.20 and 0.30% V/V) at developmental stages of 10 th and 25 th days. The plant leaves were analysed for the pesticidal residues after 5 days of their spraying with the pesticides (i.e. on 15th and 30th days of their growth). The Hexaconazole residue was recorded as below the maximum residual limit (MRL) at 0.05 to 0.15% sprays therefore, Hexaconazole can be recommended as safe pesticide to control disease in spinach at lower doses. The first foliar spray of 0.05 and 0.10% Triazophos recorded its residue below the MRL. Hence, the single foliar dose of lower concentrations of Triazophos (0.05 and 0.10% V/V) can be recommended for spinach. In fact the growth of these spinach was found to promoted when the lower doses of pesticide (0.15% V/V and below) were applied.
