GROUP H HERBICIDE

For the control of certain broadleaf weeds in rice as specified in the DIRECTIONS FOR USE table

GENERAL INSTRUCTIONS
Heavy spring rainfall may promote weed germination. These weeds should be controlled prior to Taipan application.

Resistant Weeds Warning
Taipan is a member of the pyrazole group of herbicides and acts by inhibiting 4-hyroxypehnyl-pyruvate dioxygenase (HPPDs). For weed resistance management, Taipan is a Group H herbicide. Some naturally occurring weed biotypes resistant to Taipan and other Group H herbicides may exist through normal genetic variability in any weed population. The resistant individuals can eventually dominate the weed population if these herbicides are used repeatedly. These resistant weeds will not be controlled by Taipan or other Group H herbicides. Since the occurrence of resistant weeds is difficult to detect prior to use, Bayer CropScience Pty Ltd accepts no liability for any losses that may result from the failure of Taipan to control resistant weeds.
A follow-up application of MCPA is recommended where appropriate to provide a secondary mode of action. To reduce the likelihood of resistant weeds developing it is recommended that products containing benzofenap (eg. Taipan, Viper®) not be used in consecutive rice crops.

Compatibility
Taipan is compatible in the spray tank with the following;
- chlorpyrifos,
- molinate, for barnyard grass control, only when applied by air, including by Bickley Boom, with a minimum 30 L water/ha. For SCWIIRT applications, Taipan and molinate should be applied using separate tanks.
- clomazone 480EC, only when applied by SCWIIRT from motorbike or helicopter (minimum 5 L water/ha) or Bickley boom.

Mixing
To ensure even mixing, half fill the spray tank with clean water and add the required amount of product. Agitate thoroughly then add the remainder of the water. Agitate again before spraying commences. Reseal part-used product container immediately after use.

Application
Aerial Application
Taipan may be applied by air (min. 30 L water/ha) using the coarsest droplet size.
Alternatively, apply through solid stream nozzles ie. a Bickley boom with the following setup;
- Two nozzles mounted on droppers, one either side with droppers positioned just outside the first boom hanger (28 – 35% of wingspan).
- Dropper length approximately 40-60 cm or lower below the trailing edge of the wing.
- Solid stream nozzles with bore sufficient to apply desired volume at a pressure of 240 to 310 kPa (35 to 45 psi).
- Nozzles orientated rearwards and parallel to the airstream.
- Check valves (Spraying Systems diaphragm type 12328, ¾ inch) located behind nozzle to eliminate “trailing” after shut off.
For Bickley boom application spray at a maximum wheel height of 2 m above the water surface and at a maximum swath width of 25 m. Ensure a minimum water depth of 10 cm on the high side of bays prior to treatment. A minimum application volume of 20 L/ha is recommended for Bickley boom application (except in mixture with molinate when a minimum 30 L water /ha is recommended).
Before applying Taipan to contoured bays evaluate the layout of the bays to be treated and select the optimum flight pattern to ensure all bays receive the recommended rate of Taipan.

SCWIIRT application
Taipan may be dripped directly into the bay by SCWIIRT rig (min. 5 L water/ha), e.g. by tractor, 4-wheel motorbike or helicopter.

Crop Tolerance
Taipan is safe on the major commercial varieties of rice. Subsequent crops of wheat, barley, sub-clover and canola will not be affected by use of Taipan.

DIRECTIONS FOR USE

RICE
State:
Qld, NSW & Vic
Weeds: Weeds Controlled Arrowhead, Seedlings of: alisma, starfruit, water plantain
Weeds Suppressed Dirty Dora
Rate: 2.0 L/ha
Critical comments: Apply within 10 days of commencement of flooding. For best results rapid fill of bays is recommended. Apply 12 hours after water movement has ceased. Water depth at application should be sufficient to enable distribution of product throughout the bay and to ensure full water coverage of soil is maintained for a lock-up period of 5 days. Ensure water inlets are closed securely to prevent water movement. Bays may be topped up for normal water management after the 5-day lock-up.
See comments under Application.
Water coverage should be maintained to ensure satisfactory weed control. Reduced weed control may occur where soil is exposed. Cold and/or muddy water may also reduce efficacy.
Control of seedling starfruit can be expected for up to 28 days. A follow-up treatment of MCPA may be required for complete control of dirty dora.
