6 GENERAL DESCRIPTION:

A selective, residual, translocated, pre and post emergent herbicide for controlling grasses and broadleaf weeds in wheat and turf.

7 APPLICATION METHODS AND TIPS:

For pre emergent applications apply to bare soil before planting crop. Incorporation by the planting operation improves results. Incorporate within a few days if applied to dry soil to reduce losses and movement due to wind erosion.
Best results when applied to moist soil and rain follows within 7-10 days.
For post emergent applications apply to young actively growing weeds. Rainfall within 10 days of application improves the level of control.

8 WEATHER:

Rainfast in 1-2 hours for post-emergent applications.
Frost effects: Weed control is likely to be poorer under frosty conditions.
Wind: No specific effect.
Inversions: Avoid application during low level inversions as excessive drift may occur.
Temperature: Best results at optimum temperatures for plant growth.
Delta T and relative humidity: Avoid application when Delta T is greater than
Weeds stressed by drought are less susceptible.

9 ADJUVANTS:

Use 2% spray oil (eg D-C-Trate) for post emergent applications.
Brome control about 20% less if wetter is used instead of oil.

10 WATER QUALITY:

Hard water:
Salty water:
Colloids:
pH:
Tank life: Several weeks.

11 COMPATIBILITY:

Make sure Monza is full dispersed before adding companion herbicides or adjuvants.
Trace elements.
Not compatible with foliar zinc due to antagonism reducing the effectiveness on grasses.
See HerbiGuide Compatibilities button.

12 EQUIPMENT:

Boom sprays:

Carrier volume: 40-100 L/ha. Higher volumes OK up to 1000 L/ha
Nozzles: Flat fan.
Pressure: 150-400 kPa.
Droplet size: 200 micron VMD for most applications. Use smaller droplets for post-emergent applications on Rat-tailed and Squirrel-tailed Fescue (Silver Grass or Vulpia) infestations.

Aerial application:

Not registered for aerial application.
Carrier volume: 30 L/ha and 12-16 m swath widths.

13 SPRAYER DECONTAMINATION:

Sulfonylureas
Clean up:
Clean soon after spraying to reduce the risk of forming dried deposits that may be difficult to remove.
Remove nozzles and filters and clean separately. Triple 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. This procedure is sufficient for spraying in other cereals or non selective applications.
Decontamination:
Remove the nozzles and filters and clean separately and allow to soak in a mixture of 500 mL chlorine bleach (4%) per 10 L water for at least 30 minutes.
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. Drain tank and flush with clean water for a minimum of 10 minutes to remove all traces of liquid fertilisers or adjuvants containing ammonia, such as ammonium sulphate or ammonium nitrate, before adding chlorine bleach, because bleach and ammonia will react to release a toxic gas.
Fill tank with clean water and add 300 mL household chlorine (4%) bleach per 100 L water, flush through hoses and boom then stand for 15 minutes with agitation engaged, repeat. Rinse tank, hoses and boom thoroughly with clean water to remove traces of bleach.
Rinse filters and nozzles in water and replace then rinse the whole system with water again.

A 1% solution of ammonia plus wetter is recommended in the USA. Do not mix ammonia with chlorine as this forms a toxic gas.

14 HERBICIDE RESISTANCE:

Plants tolerant to sulfosulfuron are expected to develop after repeated applications.

15 REPLANTING INTERVALS:

Do not apply to highly alkaline soils with a pH greater than 8.5.

Soil pH quoted as 1:5 soil:water suspension.

16 WITHHOLDING PERIODS:

Crop	Type	Time
All	Grazing	Not required
All	Harvest	Not required

17 RE-ENTRY PERIOD:

None required. Wear protective clothing if excessive contact is expected before the spray has dried.

18 PROTECTIVE CLOTHING:

No special protective clothing required.

19 SOIL:

Soil texture: Poorer results on ridged or cloddy soils with pre-emergence applications. Little effect on post-emergence applications.
Soil pH: Longer residual activity on alkaline soils which may affect following crops. Do not use on soils with pH greater than 8.5 (1:5 soil:water).
Soil organic matter: Relatively tolerant of high stubble loads if rain washes chemical from stubble before weed germination.
Soil moisture at application: Best results on moist soils and rain a few days for bothe pre and post-emergence applications.
Some crop yellowing or crop retardation may occur where water-logging occurs.
Weeds stressed by drought are more tolerant to sulfosulfuron.

20 MODE OF ACTION:

Uptake and translocation:

Absorbed by roots and leaves and translocated through the plant.

Physiological effects:

Inhibits the ALS (acetolactate synthase) enzyme and consequently stops root and shoot growth. Reduces or stops tillering in grasses. It stops the production of some essential amino acids.

Residual Life and Breakdown:

Selectivity:

Tolerant plants break down the herbicide.

21 SELECTIVITY:

Crop tolerance:

Some crop yellowing or crop retardation may occur where rhizoctonia, take-all, cereal cyst nematode, water-loggig, nutrient deficiency or trace element deficiency is
present. Early season crop retardation may occur on soils with a pH greater
than 8 and which are prone to zinc deficiency.

Varietal sensitivities:

Effect on Clover Species:

Damages Clover.

Effect on Medic Species:

Damages Medic.

Effect on Lucerne:

Damages Lucerne.

Effect on Native Plants:

Probably damages some native seedlings but most woody, large established plants will be tolerant.
Registered for use in conservation and wildlife areas in the USA.

22 DISEASE AND INSECT EFFECTS:

Some crop yellowing or crop retardation may occur where rhizoctonia, take-all, cereal cyst nematode, nutrient
deficiency or trace element deficiency is already
present. Early season crop retardation may occur
where the product is used on soils with a pH greater
than 8 and which are prone to zinc deficiency.

23 PLANT SYMPTOMS:

Growth normally stops within 24 hours. Symptoms of yellowing, stunting and death may take 2-3 weeks to show. Weeds may emerge after application and be stunted rather than killed. It may take some weeks for symptoms to develop.

SECONDARY EFFECTS:
