6 GENERAL DESCRIPTION:

A pre and post emergence, leaf and root absorbed, residual herbicide applied as foliar spray in water to control broadleaved and woody species in pastures and non agricultural areas.

7 APPLICATION METHODS AND TIPS:

Apply in fine weather when plants are actively growing for best results.

Keep agitated as the metsulfuron may settle.

Toxic plants may become more palatable after spraying and cause stock losses.

8 WEATHER:

Rainfast in 1 hours. Very heavy rain within 48 hours may affect results. .

Frost effects: Frost before or soon after spraying may reduce effectiveness.

Wind:

Inversions: Don't apply during inversions.

Temperature: Increase rates at high temperatures above 35 degrees C.

Delta T and relative humidity:

9 ADJUVANTS:

Wetting agents: Use a wetting agent and preferably an organosilicone product such as Pulse® for most applications.

Spray oils: Spray oils often improve results.

10 WATER QUALITY:

Hard water:

Salty water:

Colloids:

pH:

Tank life: Depends on pH. Metsulfuron may have a typical half life of a week in water.

11 COMPATIBILITY:

Trace elements.

See HerbiGuide Compatibilities button.

12 EQUIPMENT:

Boom sprays:

Carrier volume: >70 L/ha for boom or aerial applications. 1000-3000 L/ha for high volume and hand spraying treatments. Evenness of application and quantity of active ingredient per ha is more important than carrier volume.

Nozzles: Flat fan.

Pressure: 150-400 kPa.

Droplet size: 200 micron vmd is good.

Aerial application:

Carrier volume: 30-100 L/ha.

13 SPRAYER DECONTAMINATION:

Clean up:

Clean soon after spraying to reduce the risk of forming dried deposits that may be difficult to remove.

Remove nozzles and filters and clean separately. Triple 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. This procedure is sufficient for spraying in other cereals or non selective applications.

Decontamination:

Remove the nozzles and filters and clean separately and leave in a mixture of 500 mL chlorine bleach (4%) per 10 L water for at least 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. Drain tank and flush with clean water for a minimum of 10 minutes to remove all traces of liquid fertilisers or adjuvants containing ammonia, such as ammonium sulphate or ammonium nitrate, before adding chlorine bleach, because bleach and ammonia will react to release a toxic gas.

Fill tank with clean water and add 300 mL household chlorine (4%) bleach per 100 L water, flush through hoses and boom then stand for 15 minutes with agitation engaged, repeat. Rinse tank, hoses and boom thoroughly with clean water to remove traces of bleach.

Rinse filters and nozzles in water and replace then rinse the whole system with water again.

14 HERBICIDE RESISTANCE:

Tolerant plants are expected to occur and may dominate the weed population after repeated applications.

15 REPLANTING INTERVALS:

CropTime

16 WITHHOLDING PERIODS:

CropTypeTime
AllGrazing (Meat production)56 days
AllGrazing (Milk production)3 days
AllHarvest (Cutting)56 days

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 when handling the concentrate.

19 SOIL:

Soil texture:

Soil pH: Metsulfuron component persists longer in alkaline soils.

Soil organic matter:

Soil moisture at application: Best results in moist soil with light rain a day or two later. Flooding after application may reduce effectiveness.

20 MODE OF ACTION:

Aminopyralid is a disruptor of plant cell growth.

Metsulfuron inhibits acetolactate synthase (i.e. it is an ALS inhibitor).

Uptake and translocation:

Leaf and root absorbed.

Translocated

Physiological effects:

Residual Life and Breakdown:

Short residual life.

21 SELECTIVITY:

Crop tolerance:

Most grasses are tolerant.

Varietal sensitivities:

Effect on Clover Species:

Kills clover.

Effect on Medic Species:

Kills medics.

Effect on Lucerne:

Kills lucerne.

Effect on Native Plants:

Damages many native plants if they are oversprayed. Directed sprays are safe on some species but not others. Drift is not usually an issue.
