DIRECTIONS FOR USE:
RESTRAINTS:
DO NOT apply to turf, grapes, curcurbits (including melons), citrus fruit, custard apple, mango, pome fruit (apples or pears) or stone fruit (including cherries).
RATE: This table shows rates for dilute spraying. For concentrate spraying, refer to the Mixing/Application section.
CRITICAL COMMENTS: For all uses in this table: Apply by dilute or concentrate spraying equipment. Apply the same total amount of product to the target crop whether applying this product by dilute or concentrate spraying methods.

GENERAL INSTRUCTIONS
MIXING
SHAKE WELL BEFORE USE. HOWZAT SC is a liquid suspension to be mixed with water for application as a spray. Add the required quantity of HOWZAT SC to a partly filled spray tank and agitate.
Complete filling while agitating. Ensure the spray mixture is properly agitated before restarting after stoppage.
ADDITION OF WETTING AGENT
The addition of a wetting agent eg. Wetspray, to the spray mixture improves the distribution of the spray on hard to wet plants.
APPLICATION
1. TREE CROPS
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 100 L 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 the 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 spraying can then be calculated in the following way:
EXAMPLE ONLY
1. Dilute spray volume as determined above: For example 1500 L/ha.
2. Your chosen concentrate spray volume: For example 500 L/ha.
3. The concentration factor in this example is: 3 x (ie 1500 L ÷ 500 L = 3).
4. If the dilute label rate is 10 mL/100 L, then the concentrate rate becomes 3 x 10, that is 30 mL/100 L of concentrate spraying.
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.
2. OTHER CROPS
High Volume (dilute spraying): Apply in sufficient water to thoroughly wet the crop to the point of runoff. The water volume should increase as the crop size and bulk increases. Where a range of rate is specified, use the higher rate when disease pressure is high.
Low Volume (concentrate spraying): Where a rate per hectare (ha) is specified, apply in sufficient water to ensure thorough, even coverage of all plant parts. Where a range of rates is specified, use the higher rate when disease pressure is high. Where no rate per hectare is specified, the rate per hectare should be based on that which would be applied per hectare if high volume (dilute) application was used.
FUNGICIDE RESISTANCE WARNING
HOWZAT SC Fungicide is a member of the Methyl Benzimidazole Carbamate group of fungicides. For fungicide resistance management HOWZAT SC is a Group 1 fungicide. Some naturally occurring fungal populations resistant to HOWZAT SC and other Group 1 fungicides may exist through normal genetic variability in any fungal population. The resistant individuals can eventually dominate the fungi population if these fungicides are used repeatedly. These resistant fungi will not be controlled by HOWZAT SC and other Group 1 fungicides, thus resulting in a reduction in efficacy and possible yield loss.
Since the occurrence of resistant fungi is difficult to detect prior to use, Adama Australia Pty. Ltd. accepts no liability for any losses that may result from the failure of HOWZAT SC to control resistant fungi.
EXPORT OF TREATED PRODUCE
Growers should note that suitable MRLs or import tolerances may not be established in all markets for produce treated with HOWZAT SC. If you are growing produce for export, please check with Adama for the latest information on MRLs and import tolerances BEFORE using HOWZAT SC.
COMPATIBILITY
HOWZAT SC is compatible with many insecticides and fungicides, however to be sure of compatibility with any particular product check with your local dealer first.
