5.0 GENERAL DIRECTIONS FOR USE
Use only as directed. The label should be read thoroughly and
understood before making applications. Keep out of reach of
children.
Do not apply this product through any type of irrigation system.
5.1 Application Instructions
ProGibb Plus 2X contains gibberellic acid, which is an extremely
potent plant growth regulator; when applying plant growth regulators,
deviations from the label directions in the rates, timings,
water volumes, or the adoption of untested spray mixes, may result
in undesirable effects. Always consult the Valent Agricultural
Specialist in your area for the spray regimen best suited to your
conditions.
• Do not apply to plants under pest, nutritional, or water stress.
• When a range of rates is indicated, use the concentration and
spray volume recommended locally by the Valent agricultural
specialist.
• For optimum effectiveness, thorough spray coverage must be
achieved; all parts of the plant or crop must receive the spray
or desired results will not occur. Prepare solution concentrations
by mixing the required amount of product with water in a clean,
empty spray tank. Dispose of any unused spray material at
the end of each day following local, state or federal law.
• For best results, the water pH should be around 7.0, and
always below 8.5.
• ProGibb applications made under slow drying conditions
(cool to warm temperatures, medium to high relative humidity,
and no wind) will increase absorption by the plant, thus optimizing
effectiveness. Night-time applications are encouraged when
day-time conditions are not conducive to slow drying conditions.
• Product persistence: Re-apply ProGibb if significant rain occurs
within 2 hours of application.
• Compatibility: Except when specifically noted, these ProGibb
spray guidelines refer to the use of the product alone. The
use of surfactants and other additives has been reported to
be beneficial. Data concerning the compatibility of ProGibb
with other agricultural compounds, except DiPel® DF and
XenTari® DF, are not available. Valent does not assume
responsibility for unexpected results due to the tank mixing of
ProGibb Plus 2X with other products not recommended on
this label.
• DO NOT apply using ULV application methods. For aerial
applications spray volumes must be greater than 2 gallons
per acre (10 gallons per acre for tree crops).
• No preharvest interval is required for this product.
6.0 SPRAY GUIDELINES FOR GRAPE
For all grapes, application by ground sprayer provides the best
coverage. Apply as a concentrate or dilute spray in sufficient
water volume to ensure thorough wetting. It is important to wet
all flower clusters or berries thoroughly. For cultivar specific
spray rates and timings, see accompanying tables.

16-48
APPLICATION
TIMING
Make one or two applications
as a concentrate or
dilute spray.
1) Early application: spray
approximately 2 weeks
prior to color break (typically
August-November). This
timing causes the greatest
delay in rind aging and
produces the firmest rind
possible.
2) Late spray: one application
after marketable color
(typically October-December).
This late spray has been
known to cause re-greening.
OBJECTIVE/
BENEFIT
For larger berries and larger clusters
when used in conjunction with
established girdling and thinning
practices.
BERRY SIZING SPRAYS
APPLICATION
TIMING
Make one to four applications beginning
when the average berry size
reaches “target” diameter (See
below). Timing of the subsequent
sprays will be dictated by experience
in the vineyard and temperatures
occurring between sprays. Sprays
made after 15-20 days from the first
sizing spray are less effective.

– reduce fruitfulness (cluster counts) the following year.
– delay berry skin color development, sugars accumulation and overall
maturation.
• Consult a Valent representative or local specialist before sizing unfamiliar
cultivars.
7.0 SPRAY GUIDELINES FOR CITRUS
For citrus, apply in sprays of sufficient water volumes to ensure
thorough fruit wetting. In most cases, this application will cause
some drop of older mature leaves; this drop of older leaves is
inconsequential. However, application to trees of low vigor or
under stress (pest, nutritional, or water, etc.) may cause severe
leaf and/or fruit drop. Do not apply in white wash sprays in which
lime or other caustic material has produced a high pH in the
spray tank. Applications of copper fungicides and/or oils within
three weeks (before or after) the ProGibb Plus 2X application
has been known to result in significant leaf drop and fruit drop.

to target crop of young fruit.
NOTE:
• In groves that will be harvested early, do not apply the early spray as fruit
coloring will be delayed. Do not apply from January through July, as production
has occasionally been observed to be reduced the following year.
• Slower color development is to be expected in the target crop. Increased
regreening of mature fruit has been observed to occur. After marketable
color is achieved, treatment effects are possibly dissipated the longer
treated fruit remains on the tree.

EARLY: Make application
two weeks prior to color
break. Apply as a dilute
spray (AUG-SEP).
LATE: Make application
after marketable color has
developed (OCT-DEC).
NOTE:
• Do not spray groves that may be harvested early since fruit coloring will
be delayed. Treated fruit has been known to re-green if allowed to remain
on the tree for extended periods. Application made after December, or
when trees begin to break dormancy, has been observed to adversely
affect new crop. Do not use concentrate sprays. Results have been known
to vary from season to season depending on environmental conditions.
The delay in rind aging is greatest when spray is applied before color
change. This spray timing produces the firmest rind possible.

NOTE:
• The number of applications depends upon amount of desired fruit set.
Generally, more fruit will be set by 2 applications, earlier applications,
higher rates, and climatic conditions more favorable to set. Differences
in the crop strain may also interact with the above factors to affect the
degree of fruit set achieved. Reductions in final fruit size occur as a result
of excessive fruit set.

during the period of flower
bud initiation for the following
year. Consult with the
Valent representative or
local horticulturist for timings
and rates for specific
cultivars in your area. Use
sufficient water to achieve
good coverage of the
canopy.
NOTE:
• Do not spray trees in the first year. Treat in the second season for reduction
of flowering in the third season, and again in the third season if
flower reduction and fruiting is desired in the fourth season. Treat only
trees that are in good physiological condition. Discontinue treatment the
year before desired harvest.
Strawberry
(Not for use
in California)
To increase runner
production
of mother
plants.
15-25 Make a single application
to mother plants 10-30
days after planting. Plants
should have 1-6 leaves at
spraying. Apply 100 gallons
spray/acre to point of run-off.
NOTE:
• Not for use on fruiting plants. Treatments have not been as effective
on plantings set out after mid-May.
• Response varies with cultivar and location. Consult your Valent
representative or local horticulturist for specific indications.
Cranberry
(Not for use
in California)
To reduce or
completely eliminate
the crop in
the year of
application.
10-50 Make a single application
at early bloom (2-5%
scatter bloom). Use
sufficient water to ensure
thorough coverage.
NOTE:
• Applications made later than indicated have been known to result in no
effect or actually result in increased fruit set (opposite effect).
• Responses will vary with cultivar, age of the bog and location. Consult
the Valent representative or local specialist for specific information.

acre by ground sprayer or
in a minimum of 5 to 10
gallons of water per acre
by air. When applied to
promote growth of second
cutting, wait until some
regrowth has started before
spraying. Maximum benefit
is obtained when below
normal temperatures prevail
following application
and growth would be otherwise
slowed in untreated
spinach and other greens.
NOTE:
• Since the promotion of bolting has been known to occur, do not apply
after the mid-winter period or if temperatures are expected to exceed
