whiteflies. BotaniGard, which is spores of a beneficial fungus,
Beauveria

, is used for whiteflies, aphids, thrips, mealybugs, and weevils.
It is a fungus that enters insects and parasitizes them. Pyrethrums come
from the pyrethrum daisy. They are effective contact insecticides against
a broad range of pests. Spintor controls thrips. M-Pede, a soapy material
from salts of fatty acids, is a contact insecticide effective on aphids, mites,
thrips, and whiteflies. Fatty acids are the main component of the fats and
oils found in plants and animals. M-Pede is also useful as a sticker for
applying other pesticides.
The addition of one tablespoon of brown sugar per gallon of spray will
assist as a sticker/attractant for many of these products. It slows runoff of
the spray from the leaves and may act as an attractant for some insects
such as thrips, which hide in the growing point of the plant and therefore
are difficult to contact. Bugitol, an oleoresin of
Capsicum
, such as pep-
pers, is used to control and repel such insects as aphids, armyworms, leaf-
hoppers, leafminers, thrips, and whiteflies. Ultra-Pure Oil is petroleum oil
that is recommended for control of aphids, mites, leafminers, leafhoppers,
mealybugs, thrips, and whiteflies. There are many new natural insecticides
