potential foi spmy drift. The applicator and the entity authorizing spraying ar
responsible for considering all these factors when making decisions.
Spiny drib Crom applying this product may insult in damage to sensitive plan
adjacent to the treatment area. Only apply this product when the potential fo
drift m these and other adjacent sensitive areas (e.g. residential areas, bodies o
water, knovm habitat for threatened or cndangercd species, or non-target crops
is minimal. Do rtat apply when the following conditions exist that tncrcase
the likelihood of spmy drifr from intended targeu: high or gusty winds, high
tempemmres, low humidity, tempemmre inversions.
To minimize spmy drift, the applicator should be familiar with and take into
account the following drift reduction advisory information. Additional information
may be available from state enforcement agencies or the Cooperative Extension
on the application of this product
The best drift management strategy and most effecdJe way to reduce drift potential
are to apply large droplets that provide sufficient coverage and control. Applying
larger droplets reduces drift potential, but will not prevent drift if applications
are made improperly, or under unfavorable cnvironmcntal conditions (see WIND,
TEMPERATURE AND HUMIDITY, and TEMPERATURE INVERSIONS).
CONTROLLING DROPLET SIZE
• Volume-Usthigh flow rate nozzles to appy thehighestprnetrcal spmy volume.
Nozzles with hightt rated flows produce ]argm droplets.
• Pmssure-Do not cxceed the nozzle manufacturer's recommended pressures.
Far many nozzle types, lower pressure products larger droplets. When highs
flow rates are needed, use highw flow rate nozzles instead ofincreasingprcssure.
• Number of Nozzles-Usethe minimum number ofnozzla that provide uniform
coverage.
• Nozzle Orienmtion-Orienting nozzles so that the spmy is mleased pa2llel to
the airstream produces larger droplets than other'orientations and is recom-
mended prnctice. Significant deflection from the horizontal will reduce droplet
site and increase drift potential. '
• Nozzle Type-Use a nozzle type that is designed for the intended application.
With most nozzletypes, narrower spmy anglesproduce larger droplets. Consider
using low-drfr nozzles. Solid stream nozzles oriented straight back produce
the largest droplets and the lowest drift Do not use nozzles producing a mist
droplet spray.
APPLICATION HEIGHT
Making applicatioru a[ the lowest possible height (helicopter, ground driven spmy
boom) that is safe and practical reduces exposure of droplets m evaporation end
WIItd.
SWATH ADJUSTMENT- ~ -
When applications arc made with a crosswind, the swath will be displaced down-
wind. Therefore, on the up and downwind edges of the treatment area, the
applicator must compensate for this displacement by adjusting the path of the
application equipment (e.g. aircraft, ground) upwind Swath adjustment distance
should increase with increasing drift potential (higher wind, smaller droplets, etc.).
WIND
Drift potential is lowest between wind speeds of 3-10 mph. However, many
factors, including droplet size and equipment type, determine ddft potential at any
given speed. Application should be avoided below 3' mph due to variable wind
direction and high inversion potential. NOTE: Lora] terain can influence wind
patterns. Every applicator should be familiar with local wind patterns end how
thry affect spmy drift.
TEMPERATURE AND HUMIDTTY
When making applications m low relative humidity, set up equipment [o produce
]argcrdroplets to compensate for evaporation. Droplet evaporaton is most severe
when conditions aze both hot and dry. '
TEMPERATURE INVERSIONS
Drifr potential is high during a tempetmre inversion. Tcmperamre inversions
restrict vertical au mixing, which causes small suspended droplets m remain
in a concentrated cloud, which can move in unpredictable directions due to
the light variable winds common during inversions. Tcmpemmrt inversions are
chamcterizedby increasing tempemmres with altitude and arc common an nights
with fimited cloud cover and light to no wind. They begin [o form as the sun
sets end often continue into the morning. Thew presents can be indicated by
ground fog; howevtt, if fog is not prcsevt, 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. -
WIND EROSION
Avoid treating powdery dry or light sandy soils when conditions arc favorable for
wind erosion. Under these conditions, the soil surface should first be settled by
rainfall oc irrigation.
SENSITIVE AREAS ~ '
The pesticide should only be applied when the potential for drift to adjacem
sensitive areas (e.g. residrntial areas, bodies ofwamg known habim[ for threatened
or endangered species, ninon-mget crops) is minimal (e.g. when wind is blowing
away from the sensitive areas).

When usirtg spmy volumes greater than 60 ga6ons per acre, additional nonionic -
surfactant must be added at the rate of 1 quart per 100 gallons of spmy solution
to provide optimum wetting and/or concoct activity. A foam reducing agent may
