It is also synergized by PBO or MGK 264. Most ingested rotenone is detoxified efficiently via liver enzymes. Rotenone is more toxic by inhalation than by ingestion. High exposure may cause nausea, vomiting, muscle tremors and rapid breathing. Contact with rotenone may cause skin irritation and inflammation of mucous membranes.
Rotenone degrades rapidly when exposed to air and sunlight.
Alkaline materials, such as soaps, also speed rotenone degradation. Rotenone is usually mixed with Pyrethrins to provide longer lasting residual and better killing power. Neem Neem oil is an extract from the neem tree, Azadirachta indica , which is grown in tropical and subtropical climates. The most commonly used compound is azadirachtin, a complex chemical which acts as an insect feeding deterrent and growth regulator. Azadirachtin can be extracted from much of the neem tree, but most comes from oil pressed from seeds and seed kernels.
