Rates quoted in HerbiGuide are for the 250 g paraquat/L formulation. Some formulations are 200 g paraquat/L. For these products multiply the rate by 1.25 (i.e. increase the rate by 25%). For example 1000 mL of paraquat 250 is equivalent to 1250 mL of paraquat 200.

2 PRICE:

$4.29/L

3 ACTIVE INGREDIENTS: Paraquat 200-250 g/L.

4 CHEMICAL GROUP: L.

5 RELATED HERBICIDES:

Diquat, Spray.Seed.

6 GENERAL DESCRIPTION:

A post emergence, non selective, contact herbicide.

7 APPLICATION METHODS AND TIPS:

Best results when applied in low light conditions such as late afternoon, night or on cloudy days.

Ensure good coverage as paraquat is poorly translocated.

Weeds should be free from dust on leaves as paraquat is deactivated on contact with clay.

Leaves of weeds should not be wet from rain or heavy dew as spraying may cause water to unload from the leaves taking the herbicide with it. Delay spraying until leaves dried somewhat.

Do not work in spray mist. Do not continue to use if skin irritation or nose bleed occurs.

8 WEATHER:

Rainfast in 30 minutes. Light rain following application doesn't normally affect results.

Frost effects: If plant growth is reduced or plants are damaged then higher rates are required. Frost an hour or more after application has little effect on efficacy.

Wind:

Inversions: Avoid spraying during low level inversions as excessive drift may occur and cause significant spotting on downwind plants.

Temperature:

Delta T and relative humidity: Avoid application when Delta T is greater than

Soil moisture at application: Best results when soil is moist. Rate required for good control increases as plants become water stressed 1308.

9 ADJUVANTS:

Wetting agents: A wetting agent usually helps retention of the spray on the leaf.

When product rates fall below 500 mL/100 L spray, add 250 mL Agral 600 or 100 mL BS 1000 or similar non-ionic wetting agent per 100 L spray mix. Do not use alkaline or anionic wetting agents.

Spray oils: Can be used if companion herbicide o pesticide requires them.

10 WATER QUALITY:

Hard water - There may be a slight loss of activity due to ionic bonding in very hard water.

Salinity has little effect on performance.

Colloids - Significant loss of activity as the amount of clay in the water increases. If it is difficult to see a coin on the bottom of a 10 litre bucket full of water then the water should be cleared or an alternate source found.

pH -Acidic water is usually OK. Highly alkaline water may cause loss of efficacy.

Tank life:

11 COMPATIBILITY:

Most translocated herbicides are not compatible with paraquat because it rapidly desiccates the leaves of most plants which prevents movement of the companion herbicide away from the site of application. Low rates can be used in combination with some herbicides like MCPA for some species. Paraquat often leaves enough green foliage on legume species such as clovers to allow herbicides like dicamba and metsulfuron to be effectively tank mixed for improved control of these species.

Trace elements.

Zinc sulphate and copper sulphate are antagonistic with paraquat. This is caused by ionic reactions and results in a significant loss of efficacy. Manganese sulphate and calcium carbonate (lime) have lesser effects.

12 EQUIPMENT:

Not registered for aerial application mainly because of the toxicity of fine droplets.

Boom sprays:

Carrier volume: 50-500 L/ha water. Generally 100 L/ha or more is required to give good results on small grasses or on dense swards.

Nozzles: 110 degree flat fan nozzles with double overlap are adequate. Use higher water rates if using air induction nozzles or large droplet sizes.

Recommended Filter Sizes: 50-100 mesh.

Pressure: 150-400 kPa.

13 SPRAYER DECONTAMINATION:

Clean Up:

Remove filters and clean separately. Triple rinse with water or water plus 0.25% wetting agent and run through boom.

This product is corrosive to metals, particularly galvanised iron and aluminium and should not be left for long periods in tanks or equipment made of these materials.

Decontamination:

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.

14 HERBICIDE RESISTANCE:

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

Populations of Barley Grass and Silver Grass (Vulpia species) have become resistant to paraquat in Australia and resistance has been reported in Annual Ryegrass and Annual Poa elsewhere in the world.

17 RE-ENTRY PERIOD:

Wear waterproof protective clothing if in contact with the crop before the spray has dried. Dust from processing recently sprayed plants may also need controlling.

18 PROTECTIVE CLOTHING:

Wear goggles or eye protection as concentrate may damage eyes.

Where gloves when handling the concentrate and wash hands immediately if contaminated because it tends to remove finger nails.

Avoid breathing the spray mist because it is toxic and may cause nose bleeds.

If exposure to vapour, spray or dusts from dried product is expected, wear a high efficiency particulate respirator (AS1716) covering nose and mouth.

When opening the container, preparing spray and using the prepared spray wear cotton overalls buttoned to the neck and wrist and a washable hat, elbow-length PVC gloves and goggles.

Nose bleeds are an indication of exposure. Review and change operations or protection if this occurs. Some people are very sensitive to the concentrate and should avoid handling it or take extra precautions to reduce exposure.

19 SOIL:

No specific effects of texture, pH or organic matter.
