6 GENERAL DESCRIPTION:

A post emergence, leaf absorbed herbicide applied as spray for control of broadleaved weeds in cereals.

7 APPLICATION METHODS AND TIPS:

Best results on young, actively growing weeds in fine weather.
Often mixed with MCPA for broader spectrum weed control.

8 WEATHER:

Rainfast in 3 hours. Heavy rain within 48 hours of application may lead to crop damage.
Frost effects:
Wind:
Inversions: Don't apply in inversion conditions as significant drift may occur.
Temperature: Not affected much by temperature.
Delta T and relative humidity:
Rainfast in 4 hours.

9 ADJUVANTS:

Wetting agents:
Spray oils:

10 WATER QUALITY:

Hard water:
Salty water:
Colloids:
pH:
Tank life: Long.

11 COMPATIBILITY:

Trace elements.
See HerbiGuide Compatibilities button.

12 EQUIPMENT:

Boom sprays:

Carrier volume: 80-100 L/ha on label and required for coarse sprays. (More than 40 L/ha is usually OK)
Nozzles: Flat fan.
Pressure: 150-400 kPa.
Droplet size: Coarse

Aerial application:

Carrier volume: 40 L/ha or more.

13 SPRAYER DECONTAMINATION:

Clean Up:

Clean soon after spraying to reduce the risk of forming dried deposits that may be difficult to remove.
Remove filters and clean separately. Triple rinse with water or water plus 0.25% wetting agent and run through boom.

Decontamination:

Remove filters and clean separately.
Rinse with water and drain.
Quarter fill the tank with an alkali detergent (e.g. 500 mL or g of Drive, Dynamo, Omo, or Surf per 100 L water) and circulate for at least 15 minutes then run through boom. Rinse with water. Remove filters and clean separately. Replace them and rinse the whole system with water again.
Chlorine based cleaners are NOT recommended.

14 HERBICIDE RESISTANCE:

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

16 WITHHOLDING PERIODS:

CropTypeTime
AllGrazing14 days
AllHarvestNot required when used as directed on label.

17 RE-ENTRY PERIOD:

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

18 PROTECTIVE CLOTHING:

Sensitive workers should use protective clothing.
Overalls, boots and washable hat. Use gloves and face shield when handling the concentrate.

19 SOIL:

Soil texture:
Soil pH:
Soil organic matter:
Soil moisture at application: Best results when soil is moist.

20 MODE OF ACTION:

Florasulam inhibits the acetolactate synthase (ALS) enzyme which inhibits fat or lipid synthesis.

Uptake and translocation:

Physiological effects:

Residual Life and Breakdown:

Broken down by microbial action.

21 SELECTIVITY:

Tolerant plants rapidly metabolise florasulam which reduces the residue levels.

Crop tolerance:

Slight transient yellowing and some crop retardation may occur but this rarely affects grain yield. Symptoms are usually most evident 7-14 days after application.

Varietal sensitivities:

Effect on Clover Species:

Kills clovers

Effect on Medic Species:

Kills Medics

Effect on Lucerne:
