Abstract

We carried out the experiment under greenhouse conditions in plant protection department/ Ministry of Agriculture during 2017–2018 season, to assess the degradation sample of Thiophanate methyl (70% WP) fungicide in cucumber at three use rates (1.5gm/L. 3gm/L. and double spray 1.5gm/L).The researchers carried out the quantitative analysis of the fungicide residues as carbendazim was using High-performance liquid chromatography (HPLC) using QuEChERS extraction method. I found the rate of recovery was 92-106% and the comparative standard variation (RSD) were below 3.8%. Next the first order kinetics the fungicide degrades in cucumber i found the half life value in cucumber between 12.2–13.4 days unheeding of position and dose
