Pesticides Beat Odds
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
sylvania State University.
Such new pesticides, he
claims, coat chemical
companies about 5W million
dollars and about 7 years of
research and development
before the product is
marketed. The 7 years cover

the time from initial
laboratory tynthetit 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.

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. En
vironmental 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
explained.
When all of these tests are
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.

“The scientist muit
determine the range ol *
biological effectlveneM aa
well aa the level of crop
safety for a new compound.
A new chemical la screened
to determine its broadest
possible use. It is tested for
disease control, as a weed
control agent, aa a growth
regulator, as a controller of
nematodes, and as an in*
Mcctlcide. 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.

MF Tiller
A three-horsepower,
chain-drive rotary tiller is
new from Massey-Ferguson.
The MF 253, has a chain
reduction drive said to
deliver up to 30 percent more
power to the tines than
comparable worm-gear
drive models. A three hp
Briggs and Stratton turns the
tiller tines over at 100 rpm.
The 135-pound tiller carries a
suggested list price of $265.
Big Bale
Handler
Moving those big round
bales should be less of a
problem with the Model 80
Bale Mover from Sperry
New Holland. The device
carries one round bale at a
time, features an optional,
hydraulically operated bale
push-off bar. A bale can be
unloaded when the mover is
at its maximum height,
permitting placement on a
flat wagon, low-bed feed
wagon or even a pickup
truck. A two-tine unit, the
bale mover attaches to the
rear three-point hitch of a
tractor.
