Pesticides Reach Consumers
Those few new pesticides
introduced nearly every
year beat odds of 10,000 to 1
in reaching the consumer,
says Winand K. Hock, plant
pathologist and pesticides
specialist for the College of
Agriculture at The Penn*
sylvanla State University.
Such new pesticides, he
claims, cost chemical
companies about million
dollars and about 7 years of
research and development
before the product is
marketed. The 7 years cover
the time from initial
laboratory synthesis of a
compound to final govern
ment registration of a
packaged product.
Biological screening is
perhaps the area of greatest
importance and highest cost
in developing a new
chemical compound, Dr.
Hock said. This work comes
between the initial
laboratory synthesis of a
compound and field testing
of the nearly finished
product.
“The scientist must
determine the range of
biological effectiveness as
well as the level of crop
safety for a new compound.
A new chemical is screened
to determine its broadest
possible use. It is tested for
disease control, as a weed
control agent, as a growth
regulator, as a controller of
nematodes, and as an in
secticide. No stone is left
unturned,” he observed.
Once a compound shows
promising biological ac
tivity, requirements must be
met for information on toxic

effects, crop residues, and
environmental impact.
Scientists determine the
toxicity of compounds based
on ingestion, skin contact,
and inhalation by test
animals. Toxicity levels for
animals are required for
ultimate federal
registration.
The probability of a
compound causing tumors,
birth defects, or genetic
mutations must also be
examined, he pointed out.
Crop residue data are
essential as a basis for
establishing tolerances on
food and feed crops.
Tolerances represent the
maximum amount of
pesticide residue permitted
on a crop at harvest.
“Evironmental impact
studies are required to
discover any potential
hazards the chemical might
have for nontarget
organisms such as fish and
animal wildlife, as well as to
determine the behavior of
the compound in soil, air,
and water,” Dr. Hock ex
plained.

completed and the in
formation is compiled and
evaluated, only then can the
pesticide manufacturer
apply for a product
registration and petition for
tolerances, he noted. All
pesticide products in the
United States must receive a
registration from the En
vironmental Protection
Agency (EPA) before being
marketed.
Each product bears a label
describing the precise uses
permitted for that product.
Deviation from the label
constitutes a violation of
federal law. Any changes on
the label or the addition of
supplemental uses for a
particular product must first
be cleared through EPA.
“The farmer, home
gardener, and en
vironmentalist can be
assured that extensive
research has gone into any
new pesticide product. When
used properly, pesticides can
be a tremendous asset in
man’s never ending struggle
to increase the quantity and
quality of food and fiber,” he
concluded.
