2 PRICE:

$23.1/L

3 ACTIVE INGREDIENTS: Dicamba 500 g/L

4 CHEMICAL GROUP: I. Benzoic acid.

5 RELATED HERBICIDES:

Hormone herbicides.

6 GENERAL DESCRIPTION:

A selective, post emergence, foliar absorbed, translocated herbicide for control of broad-leaved weeds in grass pastures and crops.

7 APPLICATION METHODS AND TIPS:

Best results when applied to young actively growing plants.

For boom applications, 50 L/ha water or more is recommended on the label. Water rates down to 30 L/ha appear to be adequate.

For aerial application, 25 L/ha water or more is recommended on the label.

For high volume applications, apply in 1000-1500 L/ha water and spray plants until just wet.

For basal bark application mix 40 mL dicamba 500 in 10 water and apply to the lower 50 cm of the trunk for trees up to 5 cm diameter.

10 WATER QUALITY:

Hard water - There may be a slight loss of activity due to ionic bonding in very hard water.

Colloids - Some loss of activity as the amount of clay in the water increases. If it is difficult to see a coin on the bottom of a 10 litre bucket full of water then the water should be cleared or an alternate source found.

pH -Acidic water is usually OK. Highly alkaline water may cause loss of efficacy.

11 COMPATIBILITY:

Trace elements.

Zinc sulphate and copper sulphate are antagonistic with dicamba. This is caused by ionic reactions and results in a significant loss of efficacy. Manganese sulphate and calcium carbonate (lime) have lesser effects.

12 EQUIPMENT:

Boom, aerial, high volume and low volume application

14 HERBICIDE RESISTANCE:

18 PROTECTIVE CLOTHING:

19 SOIL:

20 MODE OF ACTION:

Hormone. Disrupts plant cell growth.

Uptake and translocation:

Absorbed mainly through leaves with minor absorption through roots. Highly translocated especially into woody rootstocks and rhizomes of plants like Dock, Sorrel and Spiny Emex

Physiological effects:

Residual Life and Breakdown:

21 SELECTIVITY:

Little effect on grasses. Affects many broadleaf species.

Crop tolerance:

Under some environmental conditions dicamba may reduce cereal yields (Wilhelm et al., 1995).

Varietal sensitivities:

Effect on Clover Species:

Effect on Medic Species:

Effect on Lucerne:

Effect on Native Plants:

22 DISEASE AND INSECT EFFECTS:

23 PLANT SYMPTOMS:

Curling and distortion of new growth about 1 week to one month after spraying.

SECONDARY EFFECTS:

24 TOXICITY:

Summary:

Not hazardous.

Details:

Poison schedule - S5 to S6.

Mammalian toxicity -

Acute oral LD50 - 1707 mg/kg (rats), [For comparison table salt is 3000 mg/kg]

Acute dermal LD50 - >2000 mg/kg (rabbit).

Skin - Mild irritant.

Eye - Irritating. Prolonged contact with the concentrate may cause eye damage.

Vapour inhalation - LC50 - >9.6 mg/L air (rat, 4 hour).

Chronic oral toxicity NOEL - mg/kg for two years.

Not carcinogenic, teratogenic or mutagenic test animals (i.e. does not cause cancer). At normal exposure levels there were no reproductive effects in mice. At 10-20 mg/kg/day there were reduced foetal weights, toxic effects on mothers, and increased loss of foetuses in mice.

Acceptable Daily Intake (ADI) - 0.03

NOEL - 3 mg/kg/day.

Exposure to high levels over long periods causes changes in the liver and reduced body weights in rats.

Excreted rapidly in the urine with 1-4% in faeces in rats. Mice, rats, rabbits, and dogs excreted 85% of an oral dose as unmetabolized Dicamba in the urine within 48 hours of dosing. 90-99% is excreted intact in urine eventually. This indicates that Dicamba is rapidly absorbed into the bloodstream from the gastrointestinal tract. When Dicamba was ingested daily in the feed, the concentrations in different organs reached a steady state within 2 weeks. When daily intake stopped, storage in the organs declined rapidly.

Does not bioaccumulate in mammals.

Other Species -

Birds - Practically non toxicity. LD50 - 2009 mg/kg (Mallard Duck). >10,000 mg/kg (Bobwhite Quail)

Fish - Low toxicity LC50 >35 mg/L. LC50(96 hours) 135 mg/L for rainbow trout and bluegill sunfish.

Invertebrates - Low toxicity. LC50 (96hr) 110 mg/L for Daphnia.

Bees - Not toxicity. LD50 > 100 ug/bee.

25 TOXICITY SYMPTOMS:

Loss of appetite (anorexia), vomiting, muscle weakness, slowed heart rate, shortness of breath (dyspnea), excitement or depression, urinary incontinence, cyanosis (blueness of gums and skin), exhaustion following repeated muscle spasms.

Inhalation may cause irritation of the lining of the lungs and nasal passages and loss of voice.

26 FIRST AID:

If SWALLOWED - Rinse mouth with water. Give some water to drink. Do not induce vomiting. If vomiting occurs, place patient so vomit does not enter the lungs.

If in EYES - Irrigate with plenty of water.

If on SKIN - Rinse with plenty of water, remove contaminated clothing, wash with soap and water.

If INHALED - Remove patient to fresh air.

If symptoms persist, see a doctor.

Advice to doctor - Treat symptomatically.


27 ENVIRONMENTAL FATE:

Half life in soil - <14 days in aerobic conditions. 88 days in anaerobic conditions. Typically 1-4 weeks in field soils. Degraded by micro organisms. Degradation is faster in slightly acidic soils and increase with temperature and moisture up to 50%. Degradation is slower in soils with more than 50% moisture (i.e. waterlogged soils)

Half life in water - Stable in pure water. Microbial breakdown in pond water with a half life of approximately 7 days.

Breaks down slowly in sunlight.

It has an EPA classification for soil mobility that ranges from high.

Ground water contamination. High likelihood of leaching. Low likelihood of surface runoff. Leaches from thesoil in 3-12 weeks.

Accumulation in milk and tissues - Does not accumulate.

pH stability - Stable.

Photolysis rate - Medium.

Hydrolysis half life - 30 days.

Biodegradation rate - 1-28 days in soil.

Break down in plants - Accumulates in the tips of mature leaves. Disappears from plants by exudation from the roots into the soil, metabolism in the plant or loss from leaf surfaces.

Dissipation in water - In water, microbial degradation is the main route of Dicamba disappearance. Photolysis may also occur. Aquatic hydrolysis, volatilization, adsorption to sediments, and bioconcentration are not expected to be significant.
