Insecticides - Fungicides - Disinfectants 
Poisons Cannot be Mailed—Prices are Not Prepaid Unless Specified. 
POISONS are used against surface chew¬ 
ing or biting insects. They are sprayed on 
the leaves and remain in the form of a 
thin film, or coating. Poisons act by being 
taken into the stomachs of the Insects 
while eating. In this group come Paris 
Green, Arsenate of Lead, Calcium Arsen¬ 
ate. These are arsenicals and are not rec¬ 
ommended for use on products for human 
consumption after the heads or fruits have 
been formed on account of the arsenical 
residue that is left which often causes con¬ 
demnation by the government. 
CONTACT SOLUTIONS are used to com¬ 
bat sucking insects and various kinds of 
scale. Sucking insects obtain their food by 
inserting tubes or bristles under the sur¬ 
face and sucking the plant juices. Poisons 
will not affect them. Contact solutions are 
designed to act upon these by caustic ac¬ 
tion, or by clogging up their breathing 
tubes. In this group come Fish Oil Soap, 
Dry Lime-Sulphur, Nicotine products. Pyre- 
thrums, and Rotenones. 
FUNGICIDES are used to give protection 
against infection by fungous diseases. They 
act mainly by preventing the fungus 
"spores" (which correspond to the seeds of 
higher plants) from germinating when 
they alight on protected foliage. Fungicides 
are preventives and not cures. In this 
group are Copper Hydro in powdered 
form, Dry Lime-Sulphur, Blue Vitriol, For¬ 
maldehyde.
