Abstract

An experiment was conducted during 2017-18 at AINP on Pesticide Residues, ICAR Unit- 9, AAU, Anand, Gujarat to study the dissipation behavior of bifenthrin in medium black calcareous soil under laboratory conditions. The bifenthrin was spiked in soil @ 0.06 and 0.12 μg g-1 . The experiment was conducted with three replications along with a control. The samples were collected on 0 (one hour after treatment), 1, 3, 5, 7, 10, 20, 30, 40, 50 and 60 days after treatment. Residues of bifenthrin were estimated by validated QuEChERS multi residue method using GLC equipped with electron capture detector. The mean recovery was in the range of 82.00- 96.67 percent. The residues of bifenthrin in medium black calcareous could be detected up to 40 and 50 days after application at single and double dose, respectively. Higher dose revealed longer persistence in soil than lower one. Bifenthrin showed longer persistent in medium black calcareous soil due to strong adsorption and the presence of soil cl

Conclusion

The results of the present investigation demonstrated that bifenthrin persists for more than 40 and 50 days at normal and double dose in medium black calcareous soil, respectively. Higher dose revealed longer persistence in soils than lower one. Because of strong adsorption and the presence of soil clay and organic matter, the persistence of bifenthrin in soil increases. Further studies could be conducted under different field and climatic conditions.
