6 GENERAL DESCRIPTION:

A leaf and root absorbed, pre and post emergence, selective, residual herbicide for some grass and broad leaved weeds in some pulse crops, onions, potatoes, sweet corn and triazine tolerant crops.

7 APPLICATION METHODS AND TIPS:

Best post emergence results when applied in fine weather to actively growing weeds on moist soil and rain follows a day or two later.
Best pre emergence results on trash, clod and weed free, moist soil with rain or irrigation following application.
Incorporation is useful under dry conditions. In moist conditions, no incorporation and application after planting provides better weed control.
Requires continuous agitation in the spray tank.
Cyanazine decays rapidly compared with other triazine herbicides. Late germinating weeds may not be affected.

8 WEATHER:

Requires moist soil for good weed control. Crop damage is more likely under waterlogged conditions and poor weed control is likely under dry conditions.
Rainfast in 8 hours for post emergence applications.
Frost effects: Reduced weed control from post emergence applications in frosty weather.
Wind: Drift is rarely a problem.
Inversions: Avoid spraying in inversion conditions.
Temperature: More active knockdown in warmer conditions.
Delta T and relative humidity: Crop damage may occur with post emergence applications under conditions of very high relative humidity (eg >80%)
Avoid application when Delta T is greater than

9 ADJUVANTS:

Wetting agents: Not recommended when spraying after emergence of the crop.
Spray oils: Not recommended when spraying after emergence of the crop.

10 WATER QUALITY:

Hard water:
Salty water:
Colloids:
pH:

11 COMPATIBILITY:

Trace elements.
See HerbiGuide Compatibilities button.

12 EQUIPMENT:

Boom spray: Flat fan nozzles, 150-400 kPa. 20-1000 L/ha water as a carrier.

13 SPRAYER DECONTAMINATION:

Clean up:
Remove nozzles and filters and clean separately. Rinse with soapy water (eg 500 mL or g of Drive, Dynamo, Omo or Surf per 100 L water) or water plus 0.25% wetting agent and run through boom. Rinse with water.
Decontamination:
Remove the nozzles and screens and clean separately and allow to soak in a mixture of 500 mL chlorine bleach per 10 L water for at least 30 minutes.
Triple rinse sprayer with soapy water (eg 500 mL or g of Drive, Dynamo, Omo or Surf per 100 L water) or water plus 0.25% wetting agent and run through boom. Rinse with clean water.
Rinse screens and nozzles and replace.

14 HERBICIDE RESISTANCE:

Plants resistant to group C herbicides will not be controlled.
Resistance populations of weeds are likely to develop after repeated applications. These populations usually revert to being sensitive after 5-10 years.

15 REPLANTING INTERVALS:

Crop

Time

16 WITHHOLDING PERIODS:

Crop	Type	Time
All	Harvest
All	Grazing

17 RE-ENTRY PERIOD:

Wear protective clothing if in contact with the crop before the spray has dried.

18 PROTECTIVE CLOTHING:

Overalls, boots and washable hat. Use gloves and face shield when handling the concentrate.

19 SOIL:

Crop damage is more likely on sandy soils and soils with low clay and organic matter contents. Cyanazine attaches to clay particles and higher rates are required in clay soils.
Weed control may be poorer on soils with high clay or organic matter contents.
Not recommended on the mallee soils of SA or Victoria.
Transient crop yellowing is common on duplex soils.

Soil pH.

Activity and persistence increases with soil pH.

20 MODE OF ACTION:

Inhibits photosynthesis.

Uptake and translocation:

Absorbed by roots and leaves.

Physiological effects:

Residual Life and Breakdown:

21 SELECTIVITY:

Crop tolerance:

Don't use on dry sown peas.
May cause damage to onions in the hotter months of November to February.
Transient crop yellowing is common on duplex soils.
In post emergence applications, crop may be damaged in areas where leaves are damaged by vehicle wheels.

Varietal sensitivities:

Chickpeas: Tyson is sensitive and severe damage may occur with post emergence applications.
Peas: Laura is sensitive and rates above 850 g/ha pre emergence and post emergence applications may cause damage. Wirrega is sensitive to post emergence applications.

Effect on Clover Species:

Medics are often killed especially at higher rates.

Effect on Medic Species:

Medics are often killed especially at higher rates.

Effect on Lucerne:

Established lucerne is tolerant in winter. Seedling lucerne may be damaged especially at higher rates

Effect on Native Plants:

Most established native plants are tolerant. Seedlings are often sensitive. Drift from crop spraying is unlikely to cause significant damage to native plants.

22 DISEASE AND INSECT EFFECTS:

Results in diseased and/or insect affected situations are likely to be poorer.

23 PLANT SYMPTOMS:

Yellowing of leaves, followed by necrosis then death of the plant. Symptoms usually take 14 - 21 days depending on weather conditions.
Weeds are likely to germinate and grow for a week or two on seed reserves then die.

SECONDARY EFFECTS:

24 TOXICITY:

Harmful if swallowed.
