- Intervention effect Thymol had the greatest contact toxicity to Agriotes obscurus larvae among the tested oils (LD50 196.0 μg/larva).
- Intervention effect Citronellal was significantly less toxic than thymol on contact to Agriotes obscurus larvae (LD50 404.9 μg/larva).
- Intervention effect Eugenol was significantly less toxic than thymol on contact to Agriotes obscurus larvae (LD50 516.5 μg/larva).
- Intervention effect Rosemary oil showed no significant contact toxicity to Agriotes obscurus larvae at 1600 μg/larva, the highest dose tested.
- Intervention effect Citronellal was the most toxic oil to wireworm larvae in fumigant bioassays (LD50 6.3 μg/cm).
- Intervention effect Rosemary oil was the second most toxic oil to wireworm larvae in fumigant bioassays (LD50 15.7 μg/cm), following citronellal.
- Intervention effect Eugenol was the least toxic oil to wireworm larvae in fumigant bioassays (LD50 20.8 μg/cm³).
- Intervention effect Thymol significantly inhibited seed germination and development of corn in laboratory bioassays.
- Intervention effect Citronellal significantly inhibited seed germination and development of corn in laboratory bioassays.
- Intervention effect Rosemary oil had only minimal phytotoxic effects on corn.
- Intervention effect Rosemary oil-treated seeds produced the highest number of distressed wireworms in greenhouse trials, compared with all other treatments.
- Intervention effect Thymol-treated corn seeds were the least damaged by wireworm feeding in greenhouse trials (90.7% undamaged) compared with the control.
- Intervention effect Thymol retarded corn seedling height compared with the control.
- Intervention effect Citronellal retarded corn seedling height compared with the control.
- Intervention effect Eugenol produced the lowest corn seed germination (25.3%).
- Intervention effect Citronellal had no negative impact on corn seed germination.
- Intervention effect Rosemary oil had no negative impact on corn seed germination.
- Intervention effect Thymol had no negative impact on corn seed germination.
