CLASSIC® + HARMONY® GT XP tank mixes –
improved broadleaf weed control
For control of small waterhemp, eastern black nightshade and
improved common ragweed control, CLASSIC® +
HARMONY® GT XP may be tank mixed with:
0.75 – 1.25 pt/acre “Flexstar”
0.75 – 1.5 pt/acre “Reflex”
0.5 – 1.5 pt/acre “Ultra Blazer”
4 – 6 fluid oz “Cobra”, or
8 fluid oz/acre “Phoenix”
Refer to the “Flexstar”, “Reflex”, “Ultra Blazer”, “Cobra” and
“Phoenix” labels for the appropriate rate based on the weed
sizes to be controlled. Nonionic surfactant or crop oil
concentrate must be added to the tank mix. Use as directed
below in “CLASSIC® + HARMONY® GT XP – Application
Information”.
See Precautions for CLASSIC

CLASSIC® + HARMONY® GT XP – Application
Information
• Do not use “Dash” with CLASSIC® + HARMONY® GT
XP tank mixes, or severe injury may occur.
• Under dry conditions or during cool weather a crop oil
concentrate may be used to enhance weed control. Use at
t
he rate of 4 pt per 100 gal of spray solution (0.5% v/v).
• The use of crop oil concentrate may increase temporary
crop injury.
•
When tank mixing CLASSIC® + HARMONY® GT XP
t
reatments with
D
uPont™
A
SSURE® II or other
postemergence grass herbicides, add nonionic surfactant
at 1-2 pt per 100 gal of spray solution.
CLASSIC® + HARMONY® GT XP Precautions
• Do not use crop oil concentrate when tank mixing
CLASSIC® + HARMONY® GT XP treatments with
postemergence grass herbicides such as ASSURE® II, or
severe crop injury may result.
• Do not tank mix CLASSIC® + HARMONY® GT XP
with “Poast Plus”, as severe crop injury may result.
• CLASSIC® tank mix with HARMONY® GT XP is not
recommended in the States of Alabama, Arkansas,
Florida, Georgia, Louisiana, Mississippi, South Carolina
and Texas, as excessive crop injury may occur.
CLASSIC® and “FirstRate” Herbicide
For improved Ragweed or Cocklebur control, add between
0.075 – 0.15 oz per acre “FirstRate” to 0.5 oz per acre
CLASSIC®. These tank mixes will control up to 8"
Cocklebur or Common Ragweed and up to 12" Giant
Ragweed. Use the lower amount of “FirstRate” when
weeds are less than the maximal size and under good
growing conditions. Use the higher amount of “FirstRate”
when weeds are approaching the maximum size and/or
under unfavorable growing conditions.
A good quality petroleum-based or methylated seed oil-
based Crop Oil Concentrate must be added to the tank mix
at the rate of 8 pints per 100 gallons of spray solution (1%
v/v). An ammonium nitrogen fertilizer may be added as
directed under the “Spray Adjuvants” section.
Do not use DuPont™ HARMONY® GT XP herbicide
with this tank mix of CLASSIC® plus “FirstRate”, or
unacceptable severe crop injury will result.
REGIONAL RECOMMENDATIONS
Postemergence use in Northwest Iowa
In Iowa, west of SR63 and north of I-80, one-half ounce
CLASSIC® may be applied before July 15 to soybeans
growing in well-drained, high-fertility soils of 3% or greater
organic matter and pH of 7.5 or less. Do not exceed 0.5
ounce per acre in a single growing season.
Expanded Application Timing
CLASSIC® at 1 to 3 oz/acre can be used for weed control
in all states in the CLASSIC® Central and Southern
Rotational Regions, excluding the state of Florida (see
Rotational Crop Guidelines).
CLASSIC
®
can be applied to no-till or conservation tillage
fields anytime after the Fall harvest, but prior to soybean
emergence. Do not apply to frozen ground.
• Applications must include a nonionic surfactant at
the rate of 1-2 pt per 100 gal of spray solution (0.125%-
0.25% v/v). Using the higher rate of nonionic
surfactant, particularly under hot, humid conditions,
may result in temporary crop injury.
