6 GENERAL DESCRIPTION:

Clopyralid plus diflufenican plus MCPA is an early post emergence, selective herbicide for control of a wide range of broadleaved plants in turf and grass species. The three active ingredients are absorbed through the leaves and translocated throughout the plant. Diflufenican is also absorbed through the roots and provides short term residual control of some weeds close to emergence.

7 APPLICATION METHODS AND TIPS:

Best results in fine weather when soil is moist and rain a few days later.

Young actively growing weeds are most susceptible.

Usually applied by boom spray with water as a carrier.

Avoid drift onto hormone sensitive plants as these products contain MCPA.

Don't apply if frost is imminent and allow 5-7 days for plant growth to recover after frosts.

If residual control of weeds is required use higher rates or add more diflufenican.

8 WEATHER:

Rainfast in 4 hours.

Frost effects: Poorer results in frosty weather. This may include poorer weed control and increased crop damage or more persistent symptoms. Frost a day or two after spraying generally OK. Allow 5-7 days for plants to recover from last frost before spraying.

Wind: Spray when the wind is away from desirable hormone sensitive plants.

Inversions: Avoid spraying in inversion conditions if sensitive broad-leaved plants are within two kilometres.

Temperature:

Delta T and relative humidity: Avoid application when Delta T is greater than

9 ADJUVANTS:

Wetting agents: Generally not required. Addition may cause more crop symptoms.

Spray oils: Generally not required. Addition may cause more crop symptoms.

10 WATER QUALITY:

Hard water: May cause product to drop out of solution. Jar test before use.

Salty water:

11 COMPATIBILITY:

Trace elements may drop the product out of solution. Jar test first.

Efficacy of diclofop-methyl is generally reduced by 5 - 10 % when mixed with diflufenican plus MCPA. Do NOT use more than 800 mL/ha of diflufenican plus MCPA when mixing with diclofop-methyl to minimize antagonism.

Group C soil residual herbicides such as simazine, atrazine and diuron can sensitise plants to diflufenican which can lead to better weed control but may also result in more damage to broad-leaved pasture species like clover. See HerbiGuide Compatibilities button.

12 EQUIPMENT:

Boom sprays

Water volume: 30-1000 L/ha for boom sprays (70-100 L/ha is preferred). Use finer droplets with low water volumes to keep adequate coverage.

Flat fan nozzles at 150 - 400 kPa (21.5 - 60 psi) are commonly used (e.g. 110-01 to 110-03).

Hand sprays

Water volume: 500-1000 L/ha.

Aircraft

Water volume: 30 L/ha or more. Fine droplets are required to get adequate coverage on small weeds but this increases the level of drift.

13 SPRAYER DECONTAMINATION:

Clean Up:

Remove filters and nozzles and manually clean separately. Rinse with boom cleaner and run through boom. Rinse with water.

Decontamination:

Remove filters and nozzles and manually 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. Fill with 1% solution of ammonia and leave for several hours. Triple rinse with water. Or use a commercial spray tank and equipment cleaner.

Rinse nozzles and filters in water and replace.

Don't use chlorine based cleaners.

14 HERBICIDE RESISTANCE:

Some populations of plants may be resistant or develop resistance after many applications.

15 REPLANTING INTERVALS:

16 WITHHOLDING PERIODS:

CropTypeTime
AllHarvestNot required
AllGrazingDo not graze treated turf

17 RE-ENTRY PERIOD:

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

18 PROTECTIVE CLOTHING:

Overalls, boots and washable hat. Use gloves and face shield or goggles when handling the concentrate.

19 SOIL:

Best results when applied to moist soil.

More crop damage may occur under waterlogged conditions.

Poorer weed control when soil is dry. Very poor weed control when plants are drought stressed.

20 MODE OF ACTION:

The diflufenican component inhibits carotenoid synthesis resulting in white or bleached patches on green leaves.

The clopyralid and MCPA component disrupt plant cell growth and elongation resulting in distorted plant growth.

Uptake and translocation:

Diflufenican component is absorbed by roots and shoots and translocated throughout the plant.

Clopyralid and MCPA component are absorbed through the leaves and translocated throughout the plant.

Physiological effects:

Residual Life and Breakdown:

Diflufenican component will provide about a months useful residual control of Brassica weeds like Wild Radish, Turnips, Mustards and Volunteer Canolas. Poor residual control can be expected under dry conditions, on non wetting soils, on high organic matter soils, where there has been poor coverage of the soil surface or where cultivation (or soil disturbance) after application.

The clopyralid component has limited residual activity.

The MCPA component has no useful residual activity.

21 SELECTIVITY:

Provides suppression of Dock, Paterson's Curse, Erodium, Doublegee and Chickweed in pastures if applied early in the season. Grazing 7 days after spraying generally improves control in pastures but high levels of Paterson's Curse, Capeweed or Variegated Thistle may cause stock poisoning.

Control of transplanted or stressed plants is usually poor.

Control of plants regenerating from rootstocks, rhizomes and bulbs is generally poor.

Crop tolerance:

Transient crop yellowing may occur which rarely results in yield loss unless other factors are also stressing the crop. Rates above 800 mL/ha applied before the 5 leaf stage of cereals may cause unacceptable damage.

Phalaris and Cocksfoot may have reduced production after application.

The tolerance of clover species can be variable. Winter production is often reduced after application. Application before the 8 leaf stage of clovers helps reduce this effect.

Group C soil residual herbicides such as simazine, atrazine and diuron that are in the soil from previous applications can sensitise plants to diflufenican which may result in more damage to broad-leaved pasture species like clover but also makes many broadleaf weeds more sensitive.

Varietal sensitivities:

Barley and Kulin Wheat may be damaged by label rates if applied before the 5 leaf stage.

Effect on Clover Species:

High rates cause damage.

The level of damage is often quite variable.

Effect on Medic Species:

Medics are sensitive.

Effect on Lucerne:

Established Lucerne under cereals will generally survive applications. Seedling Lucerne has marginal tolerance.

Effect on Native Plants:

Most established native plants will tolerate low rates of clopyralid plus diflufenican plus MCPA.

22 DISEASE AND INSECT EFFECTS:

Crops stressed by disease or insect attack are more likely to be damaged.

23 PLANT SYMPTOMS:

Symptoms usually take 5-10 days to appear. They include bleaching and striping of leaves often with a yellow spot surrounded by green leaf initially, distorted growth, cupping of leaves, curling of soft stems, stem splitting

SECONDARY EFFECTS:

Residual diflufenican in the soil may cause cotyledons of plants emerging after spraying to be yellowed or have a yellow eye-spot.

25 TOXICITY SYMPTOMS:

For MCPA - headache, vomiting, diarrhoea, muscular twitching, lethargy, liver and kidney function disturbance. Large ingestions may cause stupor, central nervous system depression, coma and respiratory failure.

Other symptoms may include cough, shortness of breath, nausea, vomiting, diarrhoea, abdominal pain, fever, tachycardia, low blood pressure, circulatory collapse, convulsions and coma.

26 FIRST AID:

If SWALLOWED: Do NOT induce vomiting. Give a glass of water. Keep patient at rest. Seek medical advice. Do NOT give anything by mouth to a semiconscious or unconscious patient.

If in EYES: Irrigate with plenty of water immediately and see a Doctor or ophthalmologist urgently as serious eye damage can occur.

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

If INHALED: Remove patient to fresh air. If breathing stops apply artificial respiration and seek medical advice.

Advice to doctor: Treat symptomatically. Will damage eyes and may irritate skin.

Acute toxic reactions are rare. The by-product of production, dioxin, may be implicated in subacute features such as hepatic enlargement, chloracne, neuromuscular symptoms and deranged porphyrin metabolism.

Large intentional overdoses result in coma, metabolic acidosis, myalgias, muscle weakness, elevated serum creatine kinase, myoglobinuria, irritation of the skin, eyes, respiratory tract and gut and mild renal and hepatic dysfunction.

Monitor metabolic acidosis, hyperthermia, hyperkalaemia, myoglobinuria and hepatic/renal dysfunction.
