• Nozzle Orientation - Orienting nozzles so that the spray
is emitted backwards, parallel to the airstream will
produce larger droplets than other orientations.
• Nozzle Type - Solid stream nozzles (such as disc and
c
ore with swirl plate removed) oriented straight back
p
roduce larger droplets than other nozzle types.
• Boom Length - The boom length should not exceed 3/4
of the wing or rotor length - longer booms increase drift
potential.
• Application Height - Application more than 10 ft above
the canopy increases the potential for spray drift.
BOOM HEIGHT(Ground)
Setting the boom at the lowest labeled height (if specified)
which provides uniform coverage reduces the exposure of
droplets to evaporation and wind. For ground equipment,
the boom should remain level with the crop and have
minimal bounce.
WIND
Drift potential increases at wind speeds of less than 3 mph
(due to inversion potential) or more than 10 mph. However,
many factors, including droplet size and equipment type
determine drift potential at any given wind speed. AVOID
GUSTY OR WINDLESS CONDITIONS.
Note: Local terrain can influence wind patterns. Every
applicator should be familiar with local wind patterns and
how they affect spray drift.
TEMPERATURE AND HUMIDITY
When making applications in hot and dry conditions, set up
equipment to produce larger droplets to reduce effects of
evaporation.
TEMPERATURE INVERSIONS
Drift potential is high during a temperature inversion.
Temperature inversions restrict vertical air mixing, which
causes small suspended droplets to remain close to the
ground and move laterally in a concentrated cloud.
Temperature inversions are characterized by increasing
temperature with altitude and are common on nights with
limited cloud cover and light to no wind. They begin to
form as the sun sets and often continue into the morning.
Their presence can be indicated by ground fog; however, if
fog is not present, inversions can also be identified by the
movement of smoke from a ground source or an aircraft
smoke generator. Smoke that layers and moves laterally in
a concentrated cloud (under low wind conditions) indicates
an inversion, while smoke that moves upward and rapidly
dissipates indicates good vertical air mixing.
SENSITIVE AREAS
DuPont™ CLASSIC® should only be applied when the
potential for drift to adjacent sensitive areas (e.g. residential
areas, bodies of water, known habitat for threatened or
endangered species, non-target crops) is minimal (e.g. when
wind is blowing away from sensitive areas).
SHIELDED SPRAYERS
Shielding the boom or individual nozzles can reduce the
effects of wind. However, it is the responsibility of the
applicator to verify that the shields are preventing drift and
not interfering with uniform deposition of the product.
AIR ASSISTED (AIR BLAST)
FIELD CROP SPRAYERS
Air assisted field crop sprayers carry droplets to the target
via a downward directed air stream. Some may reduce the
potential for drift, but if a sprayer is unsuitable for the
application and/or set up improperly, high drift potential can
result. It is the responsibility of the applicator to determine
that a sprayer is suitable for the intended application, is
configured properly, and that drift is not occurring.
Note: Air assisted field sprayers can affect product
performance by affecting spray coverage and canopy
penetration. Consult the application equipment section of
this label to determine if use of an air assisted sprayer is
recommended.
Do not apply this product through any type of irrigation
system.
Injury to or loss of desirable trees or vegetation may result
from failure to observe the following:
•
Do not apply CLASSIC® or drain or flush equipment on
or near desirable trees or other plants, on areas where
their roots may extend, or in locations where the chemical
may be washed or moved into contact with their roots.
• Do not use on lawns, walks, driveways, tennis courts, or
similar areas.
• Prevent spray drift to desirable plants.
• Do not contaminate any body of water.
• Do not mix/load, or use within 50 feet of all wells
included abandoned wells, drainage wells, and sink holes.
• Avoid storage of pesticides near well sites.
• Keep CLASSIC® from coming in contact with fertilizers,
insecticides, fungicides, and seeds during storage.
• Thoroughly clean all application equipment immediately
after use and prior to spraying crops other than soybeans
or peanuts.
• Calibrate sprayers only with clean water away from the
well site.
This product may be used as part of an Integrated Pest
Management (IPM) program that can include biological,
cultural, and genetic practices aimed at preventing economic
pest damage. IPM principles and practices include field
scouting or other detection methods, correct target pest
identification, population monitoring, and treating when target
pest populations reach locally determined action thresholds.
Consult your state cooperative extension service, professional
consultants or other qualified authorities to determine
appropriate action treatment threshold levels for treating specific
pest/crop systems in your area.
When herbicides that affect the same biological site of action are
used repeatedly over several years to control the same weed
species in the same field, naturally-occurring resistant biotypes
may survive a correctly applied herbicide treatment, propagate,
