6 GENERAL DESCRIPTION:

A foliar absorbed, post emergence, group K herbicide for control of young broad leaved weeds and some grasses in Beets, Mangolds and Strawberries.

7 APPLICATION METHODS AND TIPS:

Apply in fine weather when the plants are actively growing. Rainfast in 6 hours. Don't apply to wet crops. Do not apply if the temperature will exceed 30C in the 8 hours after spraying. Stressed crops may be severely damaged by application of phenmedipham. Don't use wetters.

10 WATER QUALITY:

Hard water - Do not use with extra hard water.

Colloids

pH

11 COMPATIBILITY:

Trace elements.

See HerbiGuide Compatibilities button.

Some transient foliage distortion may occur when mixed with Ethofumesate (eg Tramat).

12 EQUIPMENT:

Boom sprays with flat fan nozzles. Spraying Systems 8002 or 8003 or equivalent at 200-280 kPa are suggested on the label. 110 degree nozzles are also suitable. Air induction nozzles are suitable for broadleaf weeds and larger grasses but marginal on small fine leaved grasses. Use higher pressures and water volumes when treating small grasses.

A fine spray with 200-300 L/ha water is recommended. Lower water rates down to 50 L/ha with 8001 or 11001 nozzles (or equivalents) can be used with fine sprays and equipment that provides good coverage.

13 SPRAYER DECONTAMINATION:

Flush with water soon after spraying to avoid future blockages.

Drain tank and flush with clean water for a minimum of 10 minutes. Fill the tank with clean water and flush for 15 minutes. Remove the nozzles and screens and clean separately. Use a boom cleaning agent before spraying susceptible crops.

14 HERBICIDE RESISTANCE:

Little resistance has been found to date. Some plants may become resistant with continued use.

15 REPLANTING INTERVALS:

CropTime
All6 months

16 WITHHOLDING PERIODS: and MAXIMUM RESIDUE LIMITS:

CropTypeTime
AllHarvestNot required
AllGrazingNot required. Check before grazing failed crops.

MRL's have not been established for all export markets. Check import tolerances for produce that is intended for export before applying herbicide.

17 RE-ENTRY PERIOD:

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

19 SOIL:

No specific effects.

18 PROTECTIVE CLOTHING:

Face shield or goggles, cotton overalls, gloves, boots.

20 MODE OF ACTION:

Diverse sites of action. Carbamate but is not a cholinesterase inhibitor.

Uptake and translocation:

Foliar absorbed. Post emergence application.

Physiological effects:

Transient leaf distortion of Beets may occur when applied with ethofumesate.

Residual Life and Breakdown:

Selectivity:

Marginal selectivity especially in hot weather.

23 PLANT SYMPTOMS:

Symptoms seen in 2-3 days and plants die within 7-10 days.

SECONDARY EFFECTS:

24 TOXICITY:

Summary:

Low toxicity to mammals, birds, bees and earthworms. Toxic to aquatic organisms.

Details:

Poison schedule - Exempt.

Mammalian toxicity - Low.

Acute oral LD50 - 4000 mg/kg (rats), [For comparison table salt is 3000 mg/kg] Low toxicity.

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

Skin - Slightly irritating (rabbit). Sensitising (guinea pig).

Eye - Slightly irritating.

Vapour inhalation - LC50 - 2.6 mg/L air (rat) for 4 hours. Irritates respiratory system.

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

Not mutagenic or teratogenic (i.e. has not caused reproductive problems in animal tests). Isophorone has shown some evidence of carcinogenicity.

Acceptable Daily Intake (ADI) -

Other Species -

Birds - Low toxicity. LD50 > 2100 mg/kg.

Fish - High toxicity LC50 > 1.4-3 mg/L (rainbow trout).

Invertebrates - High toxicity EC50 6 mg/L (Daphnia 48 hr).

Bees - Low toxicity.

Arthropods - toxicity.

Earthworms - Low toxicity.

Algae - High toxicity. IC50 = 0.13 mg/L 96 hr.

25 TOXICITY SYMPTOMS:

Coughing, confusion, dizziness, headache, sleepiness, unconsciousness, allergic reactions.

No documented cases of human poisoning. Recovery is expected to be spontaneous.

26 FIRST AID:

If SWALLOWED - Wash mouth out with water. Do NOT induce vomiting. Give a glass of water to drink. Do NOT give anything by mouth to a semi conscious patient. See a doctor.

If in EYES - Irrigate with plenty of water. See a doctor.

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

If INHALED - Remove patient to fresh air. Get medical advice. Apply artificial respiration if patient stops breathing.

Advice to doctor - Treat symptomatically. Contains hydrocarbons. Vomiting may cause pneumonia.

27 ENVIRONMENTAL FATE:

Half life in soil - DT50 = 25 days. Does not accumulate in soils.

Half life in water - Isophorone evaporates from water with a half life of 7.5 days.

It has an EPA classification for soil mobility that ranges from

Ground water contamination - Unlikely to contaminate groundwater because of high Koc = 2400.

Accumulation in milk and tissues. Phenmedipham bioaccumulates and has a bioconcentration factor of 165 for bluegill sunfish and 321 for rainbow trout. Isophorone has a slight tendency to bioaccumulate with a bioaccumulation factor of 1.1-1.8 in fish.

pH stability -

Photolysis rate -

Hydrolysis half life -

Biodegradation rate - Phenmedipham is not readily biodegradable. Isophorone is readily biodegradable.
