IR ASSISTED (AIR BLAST)
F
IELD 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 "SPRAY EQUIPMENT" section of this label to
determine if use of an air assist sprayer is recommended.
RESISTANCE
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,
and become dominant in that field. Adequate control of these
resistant weed biotypes cannot be expected. If weed control is
unsatisfactory, it may be necessary to retreat the problem area
using a product affecting a different site of action.
To better manage herbicide resistance through delaying the
proliferation and possible dominance of herbicide resistant weed
biotypes, it may be necessary to change cultural practices within
and between crop seasons such as using a combination of
tillage, retreatment, tank-mix partners and/or sequential
herbicide applications that have a different site of action. Weed
escapes that are allowed to go to seed will promote the spread of
resistant biotypes. See the Weeds Controlled section of this label
for additional information on managing herbicide resistant weed
biotypes.
It is advisable to keep accurate records of pesticides applied to
individual fields to help obtain information on the spread and
dispersal of resistant biotypes. Consult your agricultural dealer,
consultant, applicator, and/or appropriate state agricultural
extension service representative for specific alternative cultural
practices or herbicide recommendations available in your area.
INTEGRATED PEST MANAGEMENT
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.
PRECAUTIONS
•
Injury to or loss of desirable trees or vegetation may result
from failure to observe the following:
Do not apply, drain or flush equipment on or near
desirable trees or other plants or 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
s
imilar areas. Prevent drift of spray to desirable plants.
•
Injury to or loss of adjacent sensitive crops and vegetation
may result from failure to observe the following:
Take all necessary precautions to avoid all direct or
indirect contact (such as spray drift) with non-target
plants or areas.
Carefully observe all sprayer cleanup instructions both
prior to and after using this product, as spray tank
residue may damage crops other than wheat, barley, oat,
triticale, corn, or soybeans.
•
Wheat, barley, oat, triticale, corn and soybean varieties
may differ in their response to various herbicides. DuPont
recommends that you first consult your state experiment
station, university, or extension agent as to sensitivity to
any herbicide. If no information is available, limit the
initial use of HARMONY® GT XP herbicide to a small
area.
•
For wheat, barley, oat, and triticale, under certain
conditions such as heavy rainfall, prolonged cold weather
(daily high temperature less than 50 Deg. F.), or wide
fluctuations in day/night temperatures prior to or soon
after HARMONY
® GT XP application, temporary
discoloration and/or crop injury may occur. To reduce the
potential of crop injury, tank mix HARMONY® GT XP
with 2,4-D (ester formulations perform best– see the
"TANK MIXTURES" section of this label) and apply after
the crop is in the tillering stage of growth.
•
HARMONY® GT XP should not be applied to corn, oat,
wheat, barley, triticale or soybeans that are stressed by
severe weather conditions, drought (including low levels
of subsoil moisture), low fertility, water-saturated soil,
disease, or insect damage, as crop injury may result. Risk
of injury is greatest when the cereal crop is in the 2 to 5-
leaf stage. Severe winter stress, drought, disease, or insect
damage following application also may result in crop
injury.
•
Do not apply to wheat, barley, oat or triticale crops
underseeded with another crop.
•
For ground applications applied to weeds when dry, dusty
field conditions exist, control of weeds in wheel track
areas may be reduced.
