Study Notes
Insecticides
- Derived from plants, used to kill or repel insects
- Examples:
- Pyrethrum (Chrysanthemum cinerariaefolium): natural insecticide, toxic to insects
- Rotenone (Derris elliptica): toxic to fish and insects, used as a pesticide
- Nicotine (Nicotiana tabacum): used as an insecticide, highly toxic to insects and mammals
Acaricides
- Derived from plants, used to kill or repel ticks and mites (acari)
- Examples:
- Rotenone (Derris elliptica): also used as an acaricide, toxic to ticks and mites
- Neem oil (Azadirachta indica): used to control ticks and mites on livestock
- Pyrethrum (Chrysanthemum cinerariaefolium): also used as an acaricide, toxic to ticks and mites
Molluscicides
- Derived from plants, used to kill or repel snails and slugs
- Examples:
- Metaldehyde (various plants): used as a molluscicide, toxic to snails and slugs
- Ferric phosphate (various plants): used as a molluscicide, toxic to snails and slugs
- Saponins (various plants): used as a molluscicide, toxic to snails and slugs
Rodenticides
- Derived from plants, used to kill or repel rodents
- Examples:
- Strychnine (Strychnos nux-vomica): highly toxic to rodents and other animals
- Coumarin (various plants): used as a rodenticide, toxic to rodents
- Warfarin (Coumadin, from Ferula foetida): used as a rodenticide, anticoagulant effects
