GENERAL DIRECTIONS FOR USE ON ORNAMENTALS

Use only as directed.  Read the label thoroughly and make sure it is
understood before making applications.  ConTegoTM Pro SL reduces
transpiration and delays wilting of ornamental plants caused by
environmental stresses.

Application instructions:

ConTegoTM Pro SL contains the active ingredient S-abscisic acid,
commonly known as S-ABA.  S-ABA is a potent Plant Growth Regulator, a
naturally occurring biochemical found in plants.  

Under drought conditions, endogenous S-ABA levels increase in leaves. 
S-ABA in turn signals stomata to close and thus reduces water loss and
controls water usage by the plant.  Similarly, exogenous application of
S-ABA causes stomata to close, reduces water usage, and thus allows
plants to conserve water.  S-ABA significantly reduces transpiration and
delays wilting of ornamental plants caused by environmental stress,
resulting in more desirable plants. 

Undesired effects can result from any deviations from the label
directions in the rates, timings, water volumes, or the adoption of
untested spray mixes, when applying ConTegoTM Pro SL.

To prepare the treatment solution, add the required amount ConTegoTM Pro
SL to a clean spray tank about half-filled with the water.  Agitate
while bringing the total volume of water to the required level.  Mix
thoroughly with agitation and bypass circulation to completely mix the
ConTegoTM Pro SL, and then add surfactant.  Discard any unused treatment
solution at the end of each day following local, state or federal law.

Best results will be achieved from applications during the cooler parts
of the day, avoiding the hottest period of the day.  To maximize
absorption and optimize product effectiveness, apply ConTegoTM Pro SL
under slow drying conditions, e.g. early in the morning or in the
evening (cool to warm temperatures, medium to high relative humidity,
and no wind).

Do not apply ConTegoTM Pro SL to plants under stress (e.g. heat, water,
disease and insect).  Injured or stressed plants will show a reduced
response to ConTegoTM Pro SL or may show phytotoxicity.

Do not overhead irrigate treated plants for at least 6 hours following
application of ConTegoTM Pro SL.

Compatibility With Other Agricultural Products

Compatibility and performance data for ConTegoTM Pro SL with other
agricultural products is not available.  Do not mix with other
agricultural products except an adjuvant (surfactant) suitable for use
on ornamental plants.

APPLICATIONS, RATES, AND TIMINGS

Ornamental PLANTS (non-food crops)

CROP	OBJECTIVE /

 BENEFIT	APPLICATION INSTRUCTIONS

Ornamental plants such as potted flowers, bedding, perennial, nursery
and foliage plants.

Although extensive testing has been conducted with ConTegoTM Pro SL, not
all varieties of ornamental plants have been evaluated.  It is highly
recommended that a small number of plants be tested for undesirable
effects of ConTegoTM Pro SL before treating a large number of plants.  

	For reduction of stress from lack of water and delay of wilting in
production and post- production of ornamental plants.

Contact Valent BioSciences Corporation for more information.

	

Spray Applications:  Apply up to 2.4 ounces of ConTegoTM Pro SL) per
gallon as a foliar spray to fully hydrated plants at 2-3 quarts of final
use solution /100 square feet.  Ensure adequate coverage of the plant.

FACTORS AFFECTING ORNAMENTAL PLANT RESPONSE TO ConTegoTM Pro SL

S-ABA is a potent Plant Growth Regulator, a naturally occurring
biochemical found in plants.  S-ABA signals stomata to close and thus
reduces water loss and controls water usage by the plant.  S-ABA
significantly reduces transpiration and delays wilting of ornamental
plants caused by environmental stress, resulting in more desirable
plants.  

In addition to proper application technique, environmental and cultural
factors will affect a plant’s response to treatment with ConTegoTM Pro
SL.  

Different varieties or cultivars within a given plant species may
require a higher or lower rate of ConTegoTM Pro SL to achieve the
desired delay in wilting.

Temperature and humidity can be an important factor in a plant’s
response to ConTegoTM Pro SL. Hot dry weather will result in a shorter
duration of effect from S-ABA applications.

Apply in the morning or evening when conditions are best for slow drying
of applied material, in order to ensure adequate absorption of the
product.  

Overhead irrigation within 6 hours after application will reduce product
activity.

Use of Adjuvants: An adjuvant suitable for use on ornamental plants will
likely increase ConTegoTM Pro SL product uptake, efficacy and potential
for negative effects. For optimal response, use ConTego with Capsil at 6
ounces per 100 gallons.  

Determining Optimal Rates:  Optimal ConTegoTM Pro SL rates will vary
according to the desired wilt delay, growing conditions & practices,
application technique, and environmental conditions.  Different
varieties or cultivars of the same species may respond differently to
ConTegoTM Pro SL.  Therefore, to determine response levels and or
phyto-toxicity potential, treat a small number of plants (using
application rates specified in Table 1) before applying ConTegoTM Pro SL
to a large number of plants.  With increasing temperature and lower
humidity consider using the higher rates within the range given in Table
1, remembering not to apply to plants that are already under stress. 

DO NOT exceed the maximum stated rate from Table 1.

ChemigatioN

Apply this product only through the following systems:

	1) Overhead sprinklers, such as impact, micro-sprinklers, or booms.

Do not apply this product through any other type of irrigation system. 
Crop injury, lack of effectiveness, or illegal pesticide residues in the
crop can result from non-uniform distribution of treated water.  If you
have questions about calibration, you should contact State Extension
Service specialists, equipment manufacturers or other experts.  Do not
connect an irrigation system (including greenhouse systems) used for
pesticide application to a public water system unless the pesticide
label prescribed safety devices for public water systems are in place. 
A person knowledgeable of the chemigation system and responsible for its
operation or under the supervision of the responsible person, shall shut
the system down and make necessary adjustments should the need arise.

CHEMIGATION SYSTEMS CONNECTED TO PUBLIC WATER SYSTEMS

Public water system means a system for the provision to the public of
piped water for human consumption if such system has at least 15 service
connections or regularly serves an average of at least 25 individuals
daily at least 60 days out of the year.  Chemigation systems connected
to public water systems must contain a functional, reduced pressure
zone, backflow preventer (RPZ) or the functional equivalent in the water
supply line upstream from the point of pesticide introduction.  As an
option to the RPZ, the water from the public water system should be
discharged into a reservoir tank prior to pesticide introduction.  There
shall be a complete physical break (air gap) between the outlet end of
the fill pipe and the top or overflow rim of the reservoir tank of at
least twice the inside diameter of the fill pipe.  The pesticide
injection pipeline must contain a functional, automatic, quick closing
check valve to prevent the flow of fluid back toward the injection pump.

The pesticide injection pipeline must contain a functional, normally
closed, solenoid-operated valve located on the intake side of the
injection pump and connected to the system interlock to prevent fluid
from being withdrawn from the supply tank when the irrigation system is
either automatically or manually shut down.  The system must contain
functional interlocking controls to automatically shut off the pesticide
injection pump when the water pump motor stops, or in cases where there
is no water pump, when the water pressure decreases to the point where
pesticide distribution is adversely affected.  Systems must use a
metering pump, such as a positive displacement injection pump (e.g.
diaphragm pump) effectively designed and constructed of materials that
are compatible with pesticides and capable of being fitted with a system
interlock.

SPRINKLER and SPRAY  -  IRRIGATION

The system must contain a functional check valve, vacuum relief valve,
and low-pressure drain appropriately located on the irrigation pipeline
to prevent water source contamination from backflow.

The pesticide injection pipeline must contain a functional, automatic,
quick closing check valve to prevent the flow of fluid back toward the
injection pump.

The pesticide injection pipeline must also contain a functional,
normally closed, solenoid-operated valve located on the intake side of
the injection pump and connected to the system interlock to prevent
fluid from being withdrawn from the supply tank when the irrigation
system is either automatically or manually shut down.

The system must contain functional interlocking controls to
automatically shut off the pesticide injection pump when the water pump
motor stops. 

The irrigation line or water pump must include a functional pressure
switch, which will stop the water pump motor when the water pressure
decreases to the point where pesticide distribution is adversely
affected.

Systems must use a metering pump, such as a positive displacement
injection pump (e.g. diaphragm pump) effectively designed and
constructed of materials that are compatible with pesticides and capable
of being fitted with a system interlock.

Fill the supply tank with the desired amount of water. Then add the
amount of ConTegoTM Pro SL required in order to achieve the selected
final use solution rate.  Agitate the mixture of ConTegoTM Pro SL
frequently during the chemigation period to assure a uniform
distribution throughout the system. 

Apply ConTegoTM Pro SL continuously for the duration of the water
application but do not exceed maximum rates and volumes stated in Table
1.  For overhead applications apply at a volume of 2 to 3 quarts of
final use solution per 100 sq. ft.
