It is impossible for anyone to keep really up to date
with the increasing number of new chemicals sold
in so many formulations and combinations under such a bewildering
array of brand names. Even as I have been writing these pages I have
been constantly changing the text to agree with recent information. I
can't even remember what I have already written without checking back
from time to time; so I certainly don't expect you to remember all you
read here. This text is for reference when you need it. For most garden
enemies there are several possible chemicals that can be used for control,
and it is your job to choose one of these from the dealer's shelf. Every
label has been registered with the U.S. Department of Agriculture and
contains either the chemical name of the active ingredient or the coined
common name, with directions for use and safety precautions. You must
learn to read this label carefully; claims made on it have been verified.
Advertisements are not registered, seldom name the active ingredient,
and often need to be taken with more than a grain of salt. If too flam
boyant statements are made, the Better Business Bureau sometimes gets
busy, but there is a time lag. Learn to read the label!
There are many combination sprays and dusts that will take care of
several garden enemies in one operation. Newest are the fruit-tree sprays
for backyard orchardists. You will have to try them out to see which fits
your combination of plants, pests, and personality.
The list presented here gives most of the chemicals mentioned in the
text and a sampling of trade names, the latter in italics. In some cases
the trade name is the only one we have to replace the long chemical
name. In other cases a common name has been coined, but we have
become too used to the trade name to change easily. Most of us think in
terms of Fermate rather than ferbam, of Parzate or Dithane Z-78 rather
There is no mention here of Krilium and other soil conditioners even
though problem soil might properly be considered a garden enemy, nor
of herbicides which require a book to themselves, nor of the new growth
inhibitor maleic hydracide, nor of fertilizers which can be applied to foli
age along with pesticides, nor of rodenticides. The list includes insecti
cides and fungicides only, and even these are limited to chemicals likely
to be used in modern home gardening.
