SUMMIT ECOPAR 20 SC HERBICIDE
SIPCAM PACIFIC AUSTRALIA PTY LTD
3 ACTIVE INGREDIENTS: Pyraflufen-ethyl 20g/L + MCPA 500g/L
Other ingredients: 1,2-benzisothiazolin-3-one
4 CHEMICAL GROUP:
5 RELATED HERBICIDES:
6 GENERAL DESCRIPTION:
A rapidly absorbed, fast acting, contact, non residual, post emergent herbicide for the control of broad leaved weeds in grass crops.
7 APPLICATION METHODS AND TIPS:
Best results on young actively growing weeds in moist soil in fine weather.
Don't apply to stressed plants.
Keep spray mix agitated.
Use higher water rates on dense weed infestations.
Keep droplet density greater than 30/cm2.
Rainfast in 6 hours.
Frost effects: Poorer results on frost affected weeds and in frosty weather
Wind: Avoid spraying within 200 m upwind of hormone sensitive plants when mixed with MCPA. Wind speeds of 2-20 kph should have less than 100 m drift.
Inversions: Avoid spraying in inversion conditions to reduce the risk of damage to off target species by drift.
Delta T and relative humidity: Avoid application when Delta T is greater than
Soil moisture at application: Best results when soil is moist at spraying.
Wetting agents: Don't use wetting agents.
Spray oils: Don't use spray oils.
10 WATER QUALITY:
See HerbiGuide Compatibilities button.
Carrier volume: 70-100 L/ha recommended on the label. Use finer nozzles if using carrier volumes down to 30 L/ha and ensure that droplet density is more than 30 droplets/cm2.
Nozzles: Flat fan.
Pressure: 150-400 kPa.
Use equipment that provides constant agitation while spraying.
13 SPRAYER DECONTAMINATION:
Clean soon after spraying to reduce the risk of forming dried deposits that may be difficult to remove.
Remove filters and clean separately. Rinse with soapy water (eg 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. Rinse with water.
Remove filters and clean then soak in 500 mL household ammonia in 10 L water for 30 minutes.
Rinse sprayer with soapy water (eg 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 allow to stand 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:
Tolerant plants are expected to occur and may dominate the weed population after repeated applications.
In 2008 there was no known resistance.
15 REPLANTING INTERVALS:
No replanting period required.
Check replanting intervals for MCPA or partner pesticides if tank mixed.
16 WITHHOLDING PERIODS:
Check withholding periods for MCPA or partner pesticides if tank mixed.
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.
20 MODE OF ACTION:
Aryl triazolinone or phenyl pyrazole group. Protox inhibitor. Disrupts membranes.
Uptake and translocation:
Contact action and rapidly absorbed but not translocated.
Interferes with chlorophyll synthesis by inhibiting the protoporphyrinogen IX oxidase (Protox) enzyme in chloroplasts. This leads to accumulation of protoporphyrinogen IX resulting in peroxidation of foliar cell membrane lipid under the presence of light, with subsequent cell membrane destruction and necrosis.
Residual Life and Breakdown:
Effect on Clover Species:
Little effect on clover.
Effect on Medic Species:
Effect on Lucerne:
Effect on Native Plants:
22 DISEASE AND INSECT EFFECTS:
23 PLANT SYMPTOMS:
Weeds usually show symptoms within 1-7 days of spraying. Yellowing followed by browning of leaves usually occurs within 1-3 days followed by death of the plant within 10-21 days. Recovery and regrowth from the base of the plant may occur.
Low oral, dermal and inhalation toxicity for mammals.
Highly toxic to algae and some aquatic organisms.
Poison schedule: S5
Acute oral LD50: Pyraflufen-ethyl >5000 mg/kg (rat), [For comparison table salt is 3000 mg/kg]
