flowers are raised primarily in East Africa, Australia,
New Guinea, and South America. A number of places in the

What Is Pyrethrum? |
|
Pyrethrum is a natural plant
oil that occurs in the pyrethrum daisy. It is found mainly
in tiny oil-containing glands on the surface of the seed
case in the tightly packed flower head and is the plant’s
own insecticide that keeps insects away. Pyrethrum is made
up of six complex chemical compounds known as pyrethrins
which work in combination to repel and kill insects.
Pyrethrum is a unique insecticide in that, used correctly,
it is relatively non toxic to humans and warm blooded
animals. It also breaks down quickly in sunlight and is
non-persistent in the environment. Because pyrethrins are
such complex and non-persistent chemicals, insect
resistance is less likely to occur |
