the name of the active ingredient present on the available products. Con-
sumers must also read the fine print and follow directions exactly if their
homegrown vegetables are to be as safe for consumption as those from
commercial growers who have to comply with the law in the matter of
residues.
Even if you follow exactly the directions for dosage given on the label, you
may have some plant injury under your particular combination of soil,
weather, and kinds of plants. Keep a notebook. Put down the date you
sprayed, the dosage used, the approximate temperature and humidity,
whether it was cloudy or sunny, in a period of drought or prolonged wet
weather. Go around later and check for burning; for leaf spotting and defo-
liation from the spray or from failure to control the disease; for leaf curling or
stunting; for too much unsightly residue. Note which varieties can take the
spray and which cannot.
The following alphabetical list includes chemicals now commercially
available, a few that are rather outmoded but still found in textbooks, a few
that were marketed in the past but have now been discontinued, and a few that
will probably be marketed before this text is published. By that time there will
be many more that should have been included, for the search for better
chemicals is unending. There will also be more that will be discontinued.
The list presented herein must be considered only as a guide. Exclusive
reliance must be placed on directions and information supplied by the man-
ufacturer or by agricultural specialists, agents, or advisors. Be sure to read
the label. Because so many of the new compounds have long, complex
chemical names, they have been given short common names by the American
Standards Association. Such common names are listed first in the following
listing. Frequently, however, the trade name is used as a common name; trade
names are listed in parenthesis following the common names. The Crop
Protection Handbook, which is published each year by Meister Publishing
Co., 37841 Euclid Ave., Willoughby, OH, 44094, gives an up-to-date listing
of pesticides. Vance Publishing publishes the Turf and Ornamental Reference
and the Crop Protection Reference (Greenbook).
As always, read and follow label directions carefully. If unsure whether
a listed product is registered in your area, contact local, state, and federal
authorities.
In the following lists, the common chemical name is given first, in bold,
followed by trade names available for professional growers of agricultural,
turf and ornamental crops and products available for consumers. Then there is
a brief description of target pathogens.
