Refer to the sequential herbicide labels for specific
information regarding use rates, application timing, crop
rotations and other restrictions and precautions.
Rotational Information
For Rotational information following 1 oz/acre CLASSIC®
in Central Region States, and up to 1.5 oz/acre applications
in Southern Region States, use Recrop Interval 2 or 3 under
the Section ‘Rotational Crop Guidelines’ depending on
whether the use was in a Central or Southren region state.
For all other Applications of CLASSIC® under the
Expanded Application Timing Use, follow the recropping
intervals given in the table below.
Crop rotation intervals noted in the table below are based on
crops grown under favorable growing conditions. Crops
grown under unfavorable environmental conditions, such as
drought, nutrient deficiency, high salts, disease and insect
pressure may demonstrate reduced tolerance to crop
protection chemicals. When deciding on a particular crop to
replant in your fields, carefully consider your particular soil
and other field conditions.

* Field Corn is defined to include only that corn grown for grain,
silage, popcorn, and seed corn. However, because seed corn
inbred lines may vary in their sensitivity to trace amounts of
herbicide carryover, DuPont cannot warrant that seed corn can be
recropped without damage or yield loss. Users should seek the
advice of their seed corn company agronomists regarding inbred
sensitivity to herbicides prior to planting any inbred lines.
**In the states of DE, KY, MD, MO bootheel, NJ, NC, SC, TN,
VA, and WV, field corn may be recropped after 9 months if the
CLASSIC® rate does not exceed 2.5 oz/acre.

SPECIFIC USES – PEANUTS
CLASSIC® is recommended for the control of Florida
beggarweed in peanuts in the states of Alabama, Florida,
Georgia, Mississippi, North Carolina, South Carolina, and
Virginia.
CLASSIC® is also recommended for the suppression of bristly
starbur in peanuts in the above mentioned states.
Timing to Crop Stage
Rate f
or Use on Peanuts
Make a single postemergence application of 1/2 oz
CLASSIC® per acre for the control of actively growing
Florida beggarweed and the suppression of bristly
starbur.
Timing to Weeds
Flor
ida Beggarweed
• Apply before Florida beggarweed reaches 10" in height or
begins to bloom.
• Florida beggarweed that regrows from mowing, cultivation,
or from a previous application of “Cadre” DG herbicide will
only be suppressed.
Br
istly Starbur
• Apply before bristly starbur reaches 10" in height.
•
Include ammonium sulfate or feed-grade urea at
2 lb per acre. Alternatively, a high-quality grade of
ammonium-based nitrogen fertilizer may be used at
8 pt per acre.
• Include a nonionic surfactant in addition to an ammonium-
based fertilizer.
• Fertilizer containing elemental sulfur should not be used.
Spray Adjuvants for Peanuts
• A nonionic surfactant must be included in the spray
solution at the rate (concentration) of 2 pt per 100 gal of
spray solution so that a minimum of 0.125% v/v of actual
nonionic surfactant is applied.
• At least 60% of the formulation should be actual nonionic
surfactant.
•
Use only EPA approved surfactants authorized for use on
food.
• Do not use a crop oil concentrate (either vegetable- or
petroleum
-
based), as crop injury will result.
CLASSIC® can be applied from 60 days after crop
emergence to 45 days before harvest. Where peanut
stands are erratic or have been replanted, do not apply
CLASSIC® until 60 days after the youngest peanuts
have emerged.
Even though CLASSIC® may be applied in the fall, for
the purposes of re-cropping, do not start counting
months for re-cropping until normal soybean planting
time in the Spring.
