% Loss (P) | |
|---|---|---|---|
| None | Sun test (for 1 h) | ||
| AGRO1 | 13.5 (11–17) | 11 (8.5–13.5) | 0 (0.74) |
| AGRO2 | 2 (0.1–7.5) | 32 (25–40) | 94 (0.003) |

Activity was determined in nanograms of toxin per square centimeter against H. virescens. The control yielded 0% ± 0% mortality. The percent loss is calculated as [(LC50)sun 1 h − (LC50)no sun]/(LC50)sun 1 h. Ninety-five percent confidence intervals are indicated in parentheses.
