GENERAL INSTRUCTIONS

 

MIXING/APPLICATION

 

Prior to pouring, shake container vigorously, then add the required quantity of STRIDENT Insecticide to water in the spray vat while stirring or with agitators in motion.

 

  

Dilute spraying

 

Use a sprayer designed to apply high volumes of water up to the point of run-off and matched to the stage of growth of crop being sprayed.

 

Calibrate and operate the sprayer to achieve even coverage throughout the crop canopy. Apply sufficient water to cover the crop to the point of run-off.  Avoid excessive run-off.

 

The required water volume may be determined by applying different test volumes, using different settings on the sprayer, from industry guidelines or specialist advice.

 

Add the amount of product specified in the Directions for Use table for each 100 L of water.  Spray to the point of run-off.

 

The required dilute spray volume, sprayer calibration and operation may all need to be changed, as the crop grows.

 

 

 

Concentrate Spraying

 

Use a sprayer designed and calibrated for concentrate spraying (that is a sprayer which applies water volumes less than those required to reach the point of run-off) and matched to the stage of crop being sprayed.

 

Calibrate and operate the sprayer to achieve even coverage throughout the crop canopy using your chosen water volume.

 

Determine an appropriate dilute spray volume (See Dilute Spraying above) for the crop canopy.  This is needed to calculate the concentrate mixing rate.

 

The mixing rate for concentrate spraying can then be calculated in the following way:

  

 

Example only

 

Dilute spray volume as determined above: For example 1500 L/ha

 

Your chosen concentrate spray volume: For example 500 L/ha

 

The concentration factor in this example is: 3 X (ie 1500 L ¸ 500 L = 3)

 

If the dilute label rate is 100 g/100 L, then the concentrate rate becomes 3 x 100, that is 300 g/100 L of concentrate spray.

 

The chosen spray volume, amount of product per 100 L of water, and the sprayer set up and operation may need to be changed as the crop grows.

 

For further information on concentrate spraying, users are advised to consult relevant industry guidelines, undertake appropriate competency training and follow industry Best Practices.

 

  

APPLICATION INSTRUCTIONS: CITRUS ONLY

 

Apply STRIDENT Insecticide in sufficient water to ensure complete wetting of all surfaces.

 

Oscillating booms

 

A spray volume of 7,000 to 12,000 L water/ha should be used for trees up to 5m high. To optimize control the following application procedures are recommended:

 

a) ground speed   2.3 to 2.75 km/h

 

b) pump pressure                3000 to 5000 kPa

 

c) oscillation rate90-110 oscillations per minute

 

d) spray pattern   adjacent cones marrying at

 

                about 1.75 m (i.e. narrow cone

 

                angle, but the maximum angle

 

                consistent with good tree

 

                penetration).

 

e) agitation            1 large paddle per 500 L;

 

                paddles should clear the

 

                bottom of the vat by about

 

                10mm and should have the

 

                same orientation.

 

f) boom set            set angle of top to match tree

 

                size.

 

Airblast sprayers

 

Airblast sprayers may be used for control of jassids/leafhoppers, but are less suitable for control of scales and mealy bugs. For jassid control, use spray volumes of approximately 5000 L/ha.

 

 

 

COMPATIBILITY

 

STRIDENT Insecticide is compatible with mancozeb and a number of other agricultural chemicals commonly used on the same crops. Please contact your supplier or Cheminova representative for further information on compatibility.

 

STRIDENT Insecticide is not compatible with Sacoa BioPest Oil or with products that are highly alkaline or highly acidic.

 

 

 

CLEANING SPRAY EQUIPMENT

 

After using STRIDENT Insecticide, empty the tank completely and drain the whole system. Thoroughly wash inside the tank using a pressure hose, drain the tank and clean all filters in the tank, pump, lines and nozzles.

 

After cleaning the tank and filters as above, quarter fill the tank with clean water and circulate through the pumps, lines, hoses and nozzles. Drain and repeat the rinsing procedure twice.

 

Rinse water should be discharged onto a designated disposal area, or if this is unavailable, onto unused land away from plants and water courses.

 

 

 

INSECTICIDE RESISTANCE WARNING

GROUP

16

INSECTICIDE

 

For insecticide resistance management STRIDENT is a Group 16 insecticide. To minimize the risk of resistance developing, a total of no more than two applications of STRIDENT Insecticide should be made on a crop per season. Some naturally occurring insect biotypes resistant to STRIDENT and other Group 16 insecticides may exist through normal genetic variability in any insect population. The resistant individuals can eventually dominate the insect population if STRIDENT or other Group 16 insecticides are used repeatedly. The effectiveness of STRIDENT on resistant individuals could be significantly reduced. Since occurrence of resistant individuals is difficult to detect prior to use, Cheminova accepts no liability for any losses that may result from the failure of STRIDENT to control resistant insects. STRIDENT may be subject to specific resistance management strategies. For further information contact your local supplier or Cheminova representative.

 

 

 

PRECAUTIONS

 

Re-entry Period: DO NOT enter treated areas without protective clothing until the spray has dried.

 

 

 

PROTECTION OF CROPS, NATIVE AND OTHER NON-TARGET PLANTS

 

DO NOT apply under weather conditions, or from spraying equipment, that may cause spray to drift onto nearby plants/crops, cropping lands or pastures.

 

 

 

PROTECTION OF LIVESTOCK

 

DO NOT allow stock to graze grasses or weeds under treated trees.

 

 

 

PROTECTION OF WILDLIFE, FISH, CRUSTACEANS AND ENVIRONMENT

 

DO NOT contaminate streams, rivers or waterways with the chemical or used containers.

 

May be toxic to crustaceans. Runoff from treated areas should be prevented from entering waterways.

 

DO NOT apply if heavy rain is imminent.

 

Irrigation should not take place within 24 hours of treatment.

 

 

 

PROTECTION OF NON-TARGET INSECTS

 

STRIDENT Insecticide at label rates of 30 to 60 mL/100L water has been demonstrated to be safe to a range of predatory and beneficial insects including bumblebees and honeybees, parasitoid wasps such as Aphytis lignanensis, Leptomastix dactylopil and Encarsia spp., predatory mites such as Phytoseiulus persimilis and Typhlodromus occidentalis and the green lacewing (Mallada signatus). STRIDENT Insecticide has no significant effect on adult ladybeetles but is known to be toxic to early instars of Cryptolaemusmontrouzieri, Chilocorus circumdatus and Harmonia conformis. STRIDENT may also affect egg hatch of these species for 2 to 3 weeks after application.

  

 

STORAGE AND DISPOSAL

  

Keep out of reach of children.

 

 

Store in the closed, original container in a cool well-ventilated area. Do not store for prolonged periods in direct sunlight.
