If using low rates of liquid nitrogen fertilizer in the spray
s
olution (less than 50% of the spray solution volume), the
addition of surfactant is necessary. Add surfactant at 1/2 pint -1
quart per 100 gal of spray solution ( 0.06 -0.25% v/v) based on
local recommendations.
When using high rates of liquid nitrogen fertilizer in the spray
solution, adding surfactant increases the risk of crop injury.
Consult your agricultural dealer, consultant, fieldsman, or
DuPont representative for a specific recommendation before
adding an adjuvant to these tank mixtures.
If 2,4-D or MCPA is included with DuPont™ HARMONY®
GT XP and the fertilizer mixture, ester formulations tend to be
more compatible (See manufacturer’s label). Additional
surfactant may not be needed when using HARMONY® GT
XP in tank mix with 2,4-D ester or MCP ester and liquid
nitrogen fertilizer solutions. Consult your agricultural dealer,
consultant, field advisor, or DuPont representative for a specific
recommendation before adding an adjuvant to these tank
mixtures.
Note: In certain areas east of the Mississippi river unacceptable crop
response may occur with use of straight or dilute nitrogen fertilizer
carrier solutions where cold temperatures or widely fluctuating
day/night temperatures exist. In these areas consult your agricultural
dealer, consultant, field advisor, or DuPont representative for a
specific recommendation before using nitrogen fertilizer carrier
solutions.
Liquid nitrogen fertilizer solutions that contain sulfur can
increase crop response.
Do not use low rates of liquid fertilizer as a substitute for a
surfactant.
Do not use with liquid fertilizer solutions with a pH less than 3.0.
SOYBEANS
APPLICA
TION TIMING (POST EMERGENCE)
HARMONY® GT XP herbicide may be applied to
soybeans any time after the first trifoliate has expanded
fully. Apply no later than 60 days before harvest.
Early-season soybean injury may result from tank-mix
applications with other registered herbicides. Injury may
manifest itself as stunting (seen as a reduction in leaf size or
internode length), yellowing leaves and/or red veins, and
necrosis in the leaves and petioles. The potential for
soybean injury is most pronounced with applications made
during hot, humid conditions, under widely fluctuating
weather or temperature conditions, or with applications to
soybeans under stress.
USE RATES IN SOYBEANS
Make a single application of HARMONY® GT XP at a rate
of 0.083 (1/12) ounce per acre for selective postemergence
broadleaf weed control on conventional soybean varieties.
HARMONY® GT XP at up to 1/3 ounce per acre is
recommended for use on soybeans designated "STS".
Severe injury or death of soybeans will result if any
soybeans not designated as "STS" are treated with more
than 1/12 ounce of HARMONY® GT XP. Multiple
applications of HARMONY® GT XP may be applied to
"STS" soybeans provided no more than a total of 1/3 ounce
is applied per season.
S
PRAY ADDITIVES
Applications of HARMONY® GT XP in soybeans must
include a nonionic surfactant or crop oil concentrate, and an
ammonium nitrogen fertilizer. See SPRAY ADJUVANTS.
WEEDS CONTROLLED
When applied to soybeans as directed, HARMONY® GT
XP will control the following weeds:
Maximum
Size (inches)
Weeds Controlled at Application
Annual Smartweeds 6
Lambsquarters 4
Pigweed
Rough (red root) 12
Other species 8
Velvetleaf 6
Wild Mustard up to 4" in dia.
Maximum
Size (inches)
Partial Control* at Application
Cocklebur 6
Jimsonweed 4
Wild Sunflower 6
*Partial Control: A visual reduction of weed population as well as
a significant loss of vigor for individual weed plants.
See WEEDS CONTROLLED in the CEREALS,
FALLOW AND PREPLANT BURNDOWN section for a
listing of weeds controlled using applications of 1/3 oz of
this product in "STS" soybeans.
TANK MIXTURES IN SOYBEANS
Harmony GT XP may be tank mixed with full or reduced rates
of other products registered for use in soybeans. However,
DuPont will not warrant crop safety or weed control of
HARMONY® GT XP tank mixtures with any other pesticide or
spray adjuvant except as specified in this label or other DuPont
supplemental labeling or technical bulletins.
Do not tank mix HARMONY
® GT XP with organophosphate
insecticides, or apply HARMONY® GT XP within 14 days
before or after an application of an organophosphate insecticide,
as severe crop injury may occur.
With Postemergence Grass Herbicides
With postemergence grass herbicides, surfactant rate
(concentration) should be 1-2 pints per 100 gallons of spray
solution (0.125%-0.25% v/v concentration). Use of a higher rate
of nonionic surfactant, particularly under hot, humid conditions,
may result in temporary crop injury. Do not use crop oil
concentrate when tank mixing HARMONY® GT XP herbicide
with postemergence grass herbicides unless specified on other
DuPont supplemental labeling. Include a nonionic surfactant
with the tank mix of HARMONY® GT XP and post grass
herbicides such as ASSURE® II herbicide.
HARMONY® GT XP may be tank mixed with
postemergence grass herbicides such as DuPont™
ASSURE® II herbicide
