  1. The control treatment was Tween 80 (TW) 0.05 % in sterile distilled water. Results followed by the same letter (comparing % survival) indicate no significant differences when using Duncan’s post-hoc test (5 % probability). Values for S50 were calculated using Log-rank survival analysis. ND = Not determined
