- Observation Roots took up nicotine and nicotine salts from solutions.
- Intervention effect Plants treated with 0.01–0.001 % nicotine became toxic to Aphis fabae.
- Observation Plants treated with nicotine contained nicotine.
- Observation Results with Phaedon cochleariae adults and larvae were less satisfactory.
- Intervention effect Nicotine watered onto soil had no observed systemic action in plants.
- Intervention effect Nicotine could not be detected in plants after soil watering.
- Intervention effect Nicotine applied repeatedly to the upper bean leaf surface killed aphids underneath.
- Observation After leaf application, evidence suggested weak longer distance nicotine translocation requiring frequent concentrated treatments.
- Observation Distant toxic action after leaf nicotine application was very weak.
- Observation Leaf absorption and subsequent translocation were not observed for nicotine salts.
- Observation Tested organic bases showed very little contact or systemic insecticidal value against aphids.
