6 GENERAL DESCRIPTION:

Bromacil is a translocated herbicide that is residual in the soil for many months to years and controls a range of grass and broadleaf weed species. It is absorbed mainly through the roots with some leaf absorption. Its main use is in citrus, pineapple and asparagus crops and for residual weed control in non crop areas. It has a long replanting interval and many plant species may be damaged up to 3 years after treatment. Do not use it near trees.

7 APPLICATION METHODS AND TIPS:

Best results when applied to trash and clod free bare soil and rain or irrigation occurs within 3-4 days of application.
Add a wetting agent if weeds up to 10 cm tall or wide are present.
Use lower rates on light soils with low clay and organic matter and higher rates on heavy soils with high clay and organic matter contents.
Do not cultivate after planting as reduced weed control and/or crop damage may occur.
Use 50 mesh or larger nozzle filters to reduce the risk of blockages. Keep well agitated.

See HerbiGuide Compatibilities button.

12 EQUIPMENT:

Boom spray - Manufacturer recommends 1000-2000 L/ha water for industrial and 250-450 L/ha water at 200-300 kPa for selective applications. Water rates down to 50 L/ha are adequate on good equipment.
Hand spraying - Manufacturer recommends 1000-2000 water L/ha at 60-800 kPa. Rates down to 200 L/ha are adequate if coverage is being achieved.
Use 50 mesh or coarser filters to prevent blockages.

13 SPRAYER DECONTAMINATION:

Clean Up:

Clean soon after spraying to reduce the risk of forming dried deposits that may be difficult to remove. Mechanically remove any caked deposits.
Remove filters and clean separately. Rinse with soapy water (e.g. 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 filters and clean then soak in 500 mL household ammonia in 10 L water for 30 minutes.
Rinse sprayer with soapy water (e.g. 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. Add 1 L of household ammonia (3% active ingredient) per 100 L water while filling the tank. Circulate through the system and spray a small quantity through the boom then leave for several hours. Rinse with soapy water or water plus 0.25% wetting agent. Rinse with water. Or use a commercial spray tank and equipment cleaner.
Rinse nozzles and filters in water and replace then rinse the whole system with water again.

14 HERBICIDE RESISTANCE:

Some populations may become tolerant after multiple use of group C herbicides.

15 REPLANTING INTERVALS:

19 SOIL:

19 SOIL:

Use lower rates on light soils with low clay and organic matter and higher rates on heavy soils with high clay and organic matter contents.

20 MODE OF ACTION:

Inhibits photosynthesis at photosystem 2.

Uptake and translocation:

Root absorbed mainly with some leaf absorption. Translocated upwards mainly in the xylem.

Physiological effects:

Residual Life and Breakdown:

Residual for more than a year. Residual life depends on the rate, soil type and rainfall.

Selectivity:

Essentially non selective.

21 SELECTIVITY:

Crop tolerance:

Kill most crops apart from asparagus, pineapple and citrus.

Varietal sensitivities:

Effect on Clover Species:

Kills clovers

25 TOXICITY SYMPTOMS:

Large ingested doses may cause dilated pupils, incoordination, salivation, vomiting, weakness, and lacrimation.
Where skin has been exposed a temporary rash may occur.
Eye contact may result in irritation, tears and blurred vision.

26 FIRST AID:

If SWALLOWED - Wash mouth out with water. Never give anything by mouth to an unconscious person. Seek medical attention if any symptoms occur.
If in EYES - Irrigate with plenty of water. Seek medical attention if irritation occurs.
If on SKIN - Rinse with plenty of water, remove contaminated clothing, wash with soap and water.
If INHALED - Remove patient to fresh air. If not breathing give artificial respiration. If breathing is difficult give oxygen. See a doctor if symptoms occur.
Advice to doctor - Treat symptomatically.
