Percent change in PMMoV gene viral signal at 4 °C, −20 °C, and −80 °C.^⁎

Time (days)	% change at 4 °C	% change at −20 °C	% change at −80 °C
7	−0.07	−36.09	−26.67
14	36.74	44.11	8.04

^⁎The percent change (% change) was calculated for all sites on day 7 and day 14 as % change = 100 × (control − treatment) / control, where control (day 0 samples directly extracted) and treatment (samples stored at 4 °C, −20 °C and − 80 °C) are the associated measurements. A positive % change indicated that the treatment result was smaller than the control, whereas a negative % change indicated the treatment had higher concentrations than the control.
