A selective, residual, pre and post emergent herbicide for controlling grasses and broadleaf weeds in wheat.
7 APPLICATION METHODS AND TIPS:
For pre emergent applications apply to bare soil before planting crop.
Best results if 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.
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
Colloids
pH
11 COMPATIBILITY:
Make sure Monza is full dispersed before adding companion herbicides or adjuvants.
14 HERBICIDE RESISTANCE:
Plants tolerant to sulfosulfuron are expected to develop after repeated applications.
18 PROTECTIVE CLOTHING:
No special protective clothing required.
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.
23 PLANT SYMPTOMS:
Yellowing, stunting and death. Weeds may emerge after application and be stunted rather than killed. It may take some weeks for symptoms to develop.
SECONDARY EFFECTS:
24 TOXICITY:
Summary:
A relatively non toxic product that is not expected to cause adverse effects under normal use patterns.
Details:
Mammalian toxicity - Low
Acute oral - Practically non toxic. LD50 - >5000mg/kg (rats), [For comparison table salt is 3000 mg/kg]
Acute dermal LD50 - Practically non toxic. >5000mg/kg (rabbit).
Skin - Slightly irritating. Non sensitising.
Eye - Slightly irritating.
Vapour inhalation - Non toxic, LC50 - >2.6 mg/L air (rat).
Chronic oral toxicity NOEL - (No Observable Effect Level) 300-1100 mg/kg/day depending on species.
Not mutagenic or teratogenic in tests (i.e. does not cause cancer or reproductive problems).
Algae - Moderately to highly toxic. EC50 3.1-0.77 mg/L.
Duckweed - Very highly toxic. IC50 0.001 mg/L.

Earthworms - No adverse effect noted.
Beetles - no adverse effect noted.
Soil microflora - No effects noted at normal use rates. May cause a temporary reduction in soil microflora and N levels at high use rates.

38. Spray Tank Clean-Up : Drain tank and flush with clean water for a minimum of 10 minutes. Ensure all traces of ammonia (eg from Ammonium sulphate or liquid fertilisers) are removed. Fill the tank with clean water and add 300 mL 4% chlorine bleach per 100 L of water. Agitate in tank fore 15 minutes. Drain through nozzles. Repeat then rinse with clean water. Remove the nozzles and screens and clean separately. NOTE - Ammonia in combination with chlorine bleach can result in the production of the toxic chlorine gas.
