ABSTRACT
Persistence and sorption behaviour of flubendiamide in two different Indian soils as affected by maize stalk biochar was studied. The persistence was more in West Bengal soil (178.6 days) than Sikkim soil (165.3 days) at 10 µg g-1 fortification level. Biochar amendment addition to soil at 5% enhanced the degradation process and half-life (T1/2) values were 103.5 and 117.4 days, respectively for biochar amended Sikkim and West Bengal soil. Sorption study through batch equilibrium method resulted the 4 h equilibrium time with adsorption 6.22% ± 0.16% and 5.26% ± 0.16% in Sikkim and West Bengal soil, respectively. Biochar addition at 5% increased the adsorption of flubendiamide to 8.12% ± 0.16% and 5.88% ± 0.16% indicating a greater influence in this process. The adsorption was more in biochar amended Sikkim soil than West Bengal soil. The values of desorption was slower than adsorption indicating a hysteresis effect having hysteresis coefficient (H1) ranges between 0.025 and 0.151 in two test soils.
