|BOXER GOLD HERBICIDE||SYNGENTA AUSTRALIA PTY LTD||EMULSIFIABLE CONCENTRATE|
3 ACTIVE INGREDIENTS:S-metolachlor 120g/L + prosulfocarb 800g/L
Other ingredients: Copolymer butanol PO/PE, dodecyl-benzene sulfonic acid Ca-salt linear in isobutanol, heavy aromatic solvent naphtha (petroleum).
4 CHEMICAL GROUP: K,E 5 RELATED HERBICIDES:
6 GENERAL DESCRIPTION:A selective, pre emergence, soil applied, root and shoot (coleoptile) absorbed, residual, upward-translocated herbicide. It controls some grasses, Toad Rush and a few broad leaved weeds 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 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.
Add a knockdown herbicide if emerged weeds are present.
Plant crop seed below the herbicide band.
Poor weed control may occur where stubble or green weed covers more than 50% of the ground.
Some crop damage has occurred when used with triple disc type planters.
Don't apply if crop has emerged as prosulfocarb component has post emergent activity and may damage the crop.
8 WEATHER:Rainfast in 0 hours for pre-emergent activity. For post emergent activity on small grasses it is expected to be rainfast within 1-3 hours.
Frost effects: No effect.
Wind: Little effect.
Inversions: No significant off target effects expected but good practice is to avoid spraying in inversion conditions.
Temperature: No effect.
Delta T and relative humidity: No effect.
Soil moisture at application: Best results when soil is moist at 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-2 leaf Annual Ryegrass but reduced the control of larger 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. Nozzles delivering medium to very coarse droplets are recommended on the label. Use finer nozzles of using low carrier volumes.
Pressure: 150-400 kPa.
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.
Remove filters and clean separately.
Rinse with water and drain.
Quarter fill the tank with an alkali detergent (eg 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.
15 REPLANTING INTERVALS:
|Susceptible crops||9 months|
16 WITHHOLDING PERIODS:
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:Reduce stubble if more than 50% ground cover.
Crop damage more likely on sandy soils especially if heavy rain follows application.
20 MODE OF ACTION:Thiocarbamates which inhibits mitosis and Amides which has diverse modes of action.
Prosulfocarb is a lipid synthesis inhibitor.
Uptake and translocation:Absorbed mainly through the roots with some absorption through leaves and the coleoptile. Movement of the herbicide is mainly in the xylem and in an upward direction in the water flow.
Prosulfocarb is absorbed through the leaves and roots and has post emergence activity.
Physiological effects:Inhibits the growth of growing points (meristems) of germinating plants.
Residual Life and Breakdown:21 SELECTIVITY:
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.
Varietal sensitivities:Short coleoptile varieties are more likely to be damaged, especially if seed treatments or other pesticides that reduce coleoptile length have been applied.
Effect on Clover Species:Little effect.
Effect on Medic Species:Little effect.
Effect on Lucerne:Little effect.
Effect on Native Plants:Little effect.
