GENERAL INSTRUCTIONS

Mixing Fill the spray vat with good quality water. With the agitation system operating, pour the required quantity of Vitra 400WG into the spray vat in a steady stream. DO NOT pre-mix Vitra 400WG with water prior to adding to the spray vat. If other pesticides are being used, fully mix the Vitra 400WG in the spray tank before adding other products. Always add and mix the Vitra 400WG first. Sprays containing Vitra 400WG should be used within 3 hours of preparation and they should be agitated continuously during this period.

WETTING AGENTS The addition of a wetting agent is required when Vitra 400WG is applied to Brassicas, Faba Beans, Peas and Onions, irrespective of the method of application. The addition of a wetting agent is also required when Vitra 400WG is applied as a concentrate spray or by aircraft. Add a wetting agent at label rates when suitable for these purposes irrespective of the spray volume applied. Where a wetting agent is not required for Vitra 400WG, one may be added if required for other pesticides.

Dilute Spraying Use a sprayer designed to apply high volumes of water up to the point of run-off and matched to the crop being sprayed. Set up 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 expert advice. Add the amount of product specified in the Directions for Use table for each 100L of water. Spray to the point of run-off. The required dilute spray volume will change and the sprayer set up and operation may also need to be changed, as the crop grows.

Concentrate Spraying Use a sprayer designed and set up 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 crop being sprayed. Set up 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 can than he calculated in the following way:

EXAMPLE ONLY

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

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

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

4. If the dilute label rate is 10mL/100L, then the concentrate rate becomes 3 x 10, that is 30mL/100L of concentrate spray.

The chosen spray volume, amount of product per 100L 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.

DECIDUOUS FRUIT Apply as a dilute or up to 2 times concentrate spray. Apply with an air blast spray calibrated to deliver the required spray volume based on PLANT ROW VOLUME and the following SPRAY VOLUME FACTORS: 75 for trees bare of foliage; 100 for trees of low foliage density. The equipment should be adjusted so that the spray is evenly distributed through the trees. Preferably apply using a sprayer fitted with cone nozzles. Concentrate sprays should only be applied with sprayers specifically designed for this purpose.

CITRUS AND LYCHEES Apply only as a dilute spray. The spray equipment should be calibrated to deliver the required spray volume based on PLANT ROW VOLUME and the following SPRAY VOLUME FACTORS: 200 for trees of low foliage density; 250 for trees of moderate foliage density; 300 for trees of high foliage density. Citrus and lychee canopies are difficult to penetrate and application using an oscillating boom sprayer is preferred to application using an air blast sprayer. If an air-blast sprayer is used, ensure that it is opening the canopy to permit entry of the spray to the interior of the tree. Spray equipment should be adjusted so that the spray is evenly distributed throughout the trees.

AVOCADOS AND MANGOES Apply as a dilute or up to 3 times concentrate spray. The spray equipment should be calibrated to deliver the required spray volume based on PLANT ROW VOLUME and the following SPRAY VOLUME FACTORS ; 75 for trees of low foliage density; 100 for trees of moderate foliage density; 125 for trees of high foliage density. The equipment should be adjusted so that the spray is evenly distributed through the trees. Preferably apply with a sprayer fitted with cone nozzles. Concentrate sprays should only be applied with sprayers specifically designed for this purpose.

VINES Apply sufficient volume to wet all leaf surfaces to the point of runoff. Apply as a medium to fine spray preferably using cone nozzles. Air-blast sprayers are recommended for application to vines with very dense foliage.

WALNUTS Apply only as a dilute spray. Apply sufficient volume to thoroughly wet blossoms, nutlets and foliage. Fine sprays are recommended for optimum results. Air-blast sprayers are suitable for young plantings, but very large mature trees may require hand direct sprays to ensure adequate coverage of their upper branches.

TOBACCO SEED BEDS Apply only as a dilute spray. Apply sufficient volume to thoroughly saturate the seedlings. Apply as a medium to fine spray directed by hand; a knapsack is suitable for this purpose.

VEGETABLES General Thorough coverage of the plant is essential for maximum effectiveness. To achieve thorough coverage:

1. Spray volumes need to be increased as the plants grow.

2. The configuration of the sprayer may need to be altered as the plants grow and change shape.

The coverage provided by the sprayer should be checked prior to each application and adjusted if necessary. This should only be done with water plus any wetting agent required.

Dilute Sprays Apply using a sprayer fitted with cone nozzles operated at pressures that produce a MEDIUM to FINE spray. The following volumes per SPRAYED HECTARE are suggested as a guide since the required volumes will vary with foliage density and size of the plants.

Concentrate Sprays Vitra 400WG may be applied to vegetables at lower volumes than those specified for dilute application, provided the CONCENTRATION of Vitra 400WG is INCREASED in inverse proportion to the reduction in volume from the specified dilute volume. EXAMPLE: If the spray volume is half the specified dilute volume, Vitra 400WG should be applied at double the dilute rate. Spray volumes for concentrate sprays should not be less than 1/3 of the equivalent dilute volume. Thus spray concentrations should not exceed 3 times the dilute concentration. Apply using a sprayer fitted with cone nozzles operated at pressures that produce a FINE spray. Refer to VEGETABLES; DILUTE SPRAYS for dilute volumes.

Rhubarb Dip Dispose of empty dip solution in a disposal pit. See Storage and Disposal section for details.

Application By Ground Rig Apply as a fine spray in a minimum of 250 L of water per ha. May be applied with hydraulic nozzles or fan-assisted rotary atomizers If hydraulic nozzles are used, cone nozzles are preferred to fan nozzles. Avoid application in very windy conditions or when the temperature and humidity cause rapid drying.

Application By Aircraft Apply in a minimum of 20 L of water per ha. May be applied with hydraulic nozzles or rotary atomizers operated to produce droplets with a VMD of around 150 microns. Avoid application in calm or very windy conditions or when the temperature and humidity cause rapid drying. To ensure good spray coverage, applications should ideally be made in a light crosswind.
