This study, which lasted for 60 days, involved collecting soil samples at five time points (1, 15, 30, 45, and 60 days) after the application of pyroxasulfone (PYR) to the soil. Most of the PYR degradation occurred within the first 30 days. However, even after 60 days, low concentrations were still detectable. By the end of the experiment, PYR degradation in the low- and high-dose treatments was 95.23% and 93.50%, respectively, compared to the first day after spraying. The degradation dynamics of PYR at low and high concentrations in sugarcane fields were also analyzed. The results indicated that the dissipation kinetics of PYR at both concentrations followed an exponential equation, with R2 > 0.92. The half-lives of PYR in the low and high concentration treatments were 14.44 days and 14.74 days, respectively.
