GROUP 3A INSECTICIDE

For control of certain insect pests of avocados and macadamias as specified in the DIRECTIONS FOR USE table.

GENERAL INSTRUCTIONS
Export of treated produce
Growers should note that suitable MRLs or import tolerances may not be established in all markets for produce treated with Bulldock. If you are growing for export, please check with Bayer Cropscience for the latest information on MRLs and import tolerances before using Bulldock.

Insecticide Resistance Warning
Some naturally occurring insect biotypes resistant to Bulldock 25 EC and other Group 3A insecticides may exist through normal genetic variability in any insect population. The resistant individuals can eventually dominate the insect population if Bulldock 25 EC or other Group 3A insecticides are used repeatedly. The effectiveness of Bulldock 25 EC on resistant individuals could be significantly reduced. Since occurrence of resistant individuals is difficult to detect prior to use, Bayer CropScience Pty Ltd accepts no liability for any losses that may result from the failure of Bulldock 25 EC to control resistant insects. Bulldock 25 EC may be subject to specific resistance management strategies. For further information contact your local supplier, Bayer  CropScience representative or local agricultural department agronomist. Application of Bulldock 25 EC to synthetic pyrethroid resistant larvae longer than 5 mm will not only be ineffective but it may increase the level of synthetic pyrethroid resistance.

Mixing
Add the required quantity of Bulldock 25 EC to water in the spray tank and mix thoroughly.

Compatibility
Bulldock 25 EC is compatible with most commonly used insecticides and fungicides. DO NOT mix concentrates together but add each to the spray tank separately. As formulations of other manufacturers' products are beyond the control of Bayer  CropScience Pty Ltd, all mixtures should be tested prior to mixing commercial quantities. As changes in climatic conditions can alter the sensitivity of plants to mixtures of sprays, Bayer CropScience cannot be responsible for the behaviour of such mixtures.

Application
Bulldock 25 EC can be applied by air or ground equipment. In common with other non-systemic insecticides adequate coverage with Bulldock 25 EC is essential for maximum effectiveness. When applying by air use a minimum of 20 litres of spray mixture per hectare. Spray in crosswinds. Do not spray in calms or when wind is light and variable in direction unless smoke indicators show spray is entering the crop uniformly. Spray application should be carried out during the cooler parts of the day or night. A spraydrift minimisation strategy should be employed at all times when aerially applying sprays to, or near, sensitive areas. The strategy envisaged is exemplified by the cotton industry’s Best Management Practice Manual.

Special instructions for Avocadoes and Macadamias
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 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: 3X (ie 1500 L ÷ 500 L = 3)
4. If the dilute label rate is 25 mL/100 L, then the concentrate rate becomes 3 x 25, that is 75 mL/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.
- Do not use a concentrate rate higher than that specified in the Critical Comments.
- For further information on concentrate spraying, users are advised to consult relevant industry guidelines, undertake
appropriate competency training and follow industry Best Practices.

DIRECTIONS FOR USE
Restraint
DO NOT apply if rain is expected within 6 hours

AVOCADOS
Pest: Fruitspotting bug
Rate:
Dilute spraying 25 to 50 mL/100 L water
Concentrate spraying Refer to the Application section
WHP: 7 days
Critical comments: Apply by dilute or concentrate spraying equipment. Regularly monitor avocado trees for fruitspotting bug presence and spray when numbers exceed action thresholds. Use the higher rate for high levels of infestation or likelihood of continuous reinfestation. Repeat application when numbers exceed the action threshold. Apply a maximum of 4 sprays with a minimum of 21 days between consecutive sprays.
Apply the same total amount of product to the target crop whether applying this product by dilute or concentrate spraying methods. Can be used at up to 5 X concentrate. Do not use at concentrate rates greater than 250 mL/100 L of water (i.e. 5X concentrate).

NOT TO BE USED FOR ANY PURPOSE, OR IN ANY MANNER, CONTRARY TO THIS LABEL UNLESS AUTHORISED UNDER APPROPRIATE LEGISLATION
