6 GENERAL DESCRIPTION:

A selective, pre emergence, soil applied, root and shoot (coleoptile) absorbed, residual, upward-translocated agricultural herbicide. It inhibits meristematic growth. Movement in the phloem is unlikely. It controls some grasses in cereal and broad leaved crops.

7 APPLICATION METHODS AND TIPS:

Best results on clod and trash free, moist soil and incorporated mechanically within 7 days of spraying and 5-10 mm rain follows within 10 days.

Avoid cultivation that throws or concentrates herbicide in the seeding furrow.

Increase the level of incorporation under dry conditions.

Apply before or soon after the germination of seeds.

Plant crop seed below the herbicide band.

Add a knockdown herbicide if emerged weeds are present.

Poor weed control may occur where stubble or green weed covers more than 50% of the ground.

Don't apply if crop has emerged as prosulfocarb has post emergent activity and may damage the crop.

Don't apply to sodic soils or those prone to waterlogging.

Crop damage may occur with single disk seeding systems.

8 WEATHER:

Rainfast immediately for pre-emergent activity. For post emergent activity on small grasses it is expected to be rainfast within 1-3 hours.

Frost effects: No or little effect.

Wind: Little effect.

Inversions: Avoid spraying in inversion conditions to reduce risk of drift.

Temperature: No effect.

Delta T and relative humidity: No effect.

Soil moisture at application: Best results when soil is moist at the time of spraying and rain to wet the top 2-4 cm follows within a week of spraying. In dry soils use more thorough mechanical incorporation. Avoid using on soils prone to water logging as increased crop damage may occur.

9 ADJUVANTS:

Wetting agents: Not required. Compatible with most wetting agents and can be used if partner pesticides require them.

Spray oils: Not required. Compatible with most spray oils and can be used if partner pesticides require them.

10 WATER QUALITY:

Hard water: Tolerates hard water.

Salty water: Tolerates salty water.

Colloids: Tolerates clay and colloids in water.

pH: Tolerates the normal range of field pH.

Tank life: Several weeks.

11 COMPATIBILITY:

Trace elements. Compatible with Ammonium nitrate (with constant agitation).

When tank mixed with glyphosate or diquat plus paraquat it improves the control of emerging to 2 leaf Annual Ryegrass.

See HerbiGuide Compatibilities button.

12 EQUIPMENT:

Boom sprays:

Carrier volume: Minimum of 50 L/ha water (or 70 L/ha in minimum tillage situations) recommended on label. If using lower rates, ensure the equipment can deliver it evenly to the soil.

Nozzles: Flat fan.

Pressure: 150-400 kPa.

Droplet size: Nozzles delivering a coarse to very coarse droplet spectrum are recommended on the label. Use finer nozzles if mixing with knockdown herbicides and drift is not an issue.

Aerial application:

Carrier volume: 30 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 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 twice with water.

Chlorine based cleaners are NOT recommended.

14 HERBICIDE RESISTANCE:

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

Controls group D resistant Annual Ryegrass.

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: Crop damage is more likely on sandy, leaching or low organic matter soils especially if heavy rain follows application.

Soil pH:

Soil organic matter: Crop damage is more likely on low organic matter soils.

Soil moisture at application: Best results on moist soil and light rain follows within a few days.

Reduce stubble if more than 50% ground cover.

20 MODE OF ACTION:

Prosulfocarb is a lipid synthesis inhibitor.

It inhibits the meristematic growth.

Movement in the phloem is unlikely.

Uptake and translocation:

Prosulfocarb is absorbed through the leaves and roots and has pre and post emergence activity. It is only translocated upwards in the xylem.

Physiological effects:

Residual Life and Breakdown:

It has a half-life in soil of 35 days and is not persistent. It is slightly mobile in soil and is mainly broken down by microbial action.

In water it has a half-life of 159-279 days and is persistent.

21 SELECTIVITY:

The physiological selectivity of prosulfocarb occurs due to the ability of cereals or crop species to metabolise it to inactive compounds more rapidly than susceptible species.

Crop tolerance:

Selectivity is a combination of positioning the herbicide away from the crop seed and the physiological tolerance of the crop. Heavy rain, waterlogging, shallow sowing or deep incorporation of furrow collapse that exposes the crop seed to high levels of the herbicide is likely to lead to crop damage.

Crop damage may occur with single disk seeding systems.

Varietal sensitivities:

Cereal varieties with short coleoptile lengths are more likely to be sensitive especially if applied with other products like some fungicides that shorten the coleoptile length.

Effect on Clover Species:

Little effect.

Effect on Medic Species:

Little effect.

Effect on Lucerne:

Little effect.

Effect on Native Plants:

Little effect.

22 DISEASE AND INSECT EFFECTS:

23 PLANT SYMPTOMS:

Susceptible plants may germinate but soon wilt and die. Roots are stunted.
