General Instructions

 

Mixing

 

Add the required quantity of product to water in the spray tank and agitate to give even mixing. Agitate again if left standing.

 

WETTING AGENT

This product contains a wetting agent and additional wetter is not required unless high volume spraying results in excessive dilution of wetter content. This will occur when product rates fall below 400 mL per 100 L of spray. Under such circumstances wetter should be added at the rate of 100 mL of Agral or 60 mL of BS1000 per 100 L of spray mix. Where Fat Hen or Portulaca are present in orchard or vineyard situations, extra wetter should be used when this product ration is less than 800 mL per 100 L. Add wetter at double the above recommendations. DO NOT use alkaline or anionic wetting agents.

 

CLEAN WATER

Mix this product with clean water only. Water should be clean and free from clay, silt and algae. Providing it meets this requirement, saline water, water collected from roofs, bore water, dam water and water from creeks may be used.

 

Application

 

Cereals and Broadacre Spraying

Use only through a properly calibrated boom spray which should be fitted with flat fan jets and adjusted to a height to give at least double overlap of the spray at the top of the weeds being sprayed. Spraying pressures should be in the range of 200-300 kPa. Speed of travel should be in the range of 6-15 km/hr. It is essential that a good marking system be used. If a disc marker is used, it must be mounted so as to turn the soil back onto the area sprayed. It is essential to obtain good leaf coverage with the spray and volumes of dilute spray must be adjusted according to density of weed growth. 100 L/ha may be used for seedlings or well grazed weeds up to 2 cm high. For plant height 2-5 cm use 150 L/ha and up to 6-10 cm use 200 L/ha. Spray volumes may be as low as 50 L/ha (30 L/ha in WA) for weed growth below 5 cm high, or for spray topping and hay freezing. Equipment must be appropriate to this volume, properly calibrated and fi tted with spraying tips designed to give droplets in the 200-250 microns Volume Median Diameter range.

 

HIGH VOLUME APPLICATION

Higher volumes will generally be required to give good coverage of weed growth in situations other than those specifi ed under cereals and other broadacre crops. Wash spray equipment with clean water immediately after use. This product is highly corrosive to metals, particularly galvanised iron and aluminium and should not be left for long periods in tanks or equipment made of these materials. For ground application only - do not use this formulation through aircraft, misting machines or hand-held ultra low volume controlled droplet applicators (CDA units).

 

Compatibility

This product combines satisfactorily with the soil active herbicides Atrazine 900 WDG, Diuron 900 WDG and Simazine 900 WDG where prolonged weed control is required as well as a quick knockdown. This product is compatible with Agral, BS1000, Reglone, Spray-Out 250, Banvel 200, Banvel M, MCPA Amine (to and Spark (oxyfluorfen).

 

Conditions for Best Results

Avoid spraying plants under stress from waterlogging, frost, drought etc. or covered with dust and soil. Results will be better if application is made in dull weather or at the end of the day. Light rain following spraying will not affect results. Avoid drift into neighbouring crops.

 

Restraints

 

DO NOT add wetter unless spraying at high volume. Where PARAQUAT 250 SL is mixed with water at less than 400 mL/100 L of water, add 100 mL Agral or 60 mL BS1000 per 100 L of spray.

DO NOT spray plants which are waterlogged, under stress of any kind or covered with soil or dust.

 

DO NOT spray plants covered with heavy dew, but rain following spraying will not affect results.

 

DO NOT sow or cultivate for 1 hour after spraying but operations should commence within 7 days.

 

For ground application only - DO NOT use through aircraft, misting machines or hand-held ultra low volume controlled droplet applicators (CDA units).

 

Resistance Warning

 

Cheminova PARAQUAT 250 SL Herbicide is a member of the bipyridyls group of herbicides. PARAQUAT 250 SL has the inhibitor of photosynthesis at photosystem 1 mode of action. For weed resistance management PARAQUAT 250 SL is a Group L herbicide. Some naturally-occurring weed biotypes resistant to PARAQUAT 250 SL and other Group L herbicides may exist through normal genetic variability in any weed population. The resistant individuals can eventually dominate the weed population if these herbicides are used repeatedly. These resistant weeds will not be controlled by PARAQUAT 250 SL or other Group L herbicides. Since the occurrence of resistant weeds is diffi cult to detect prior to use Cheminova Pty. Ltd. accepts no liability for any losses that may result from the failure of PARAQUAT 250 SL to control resistant weeds.

 

This product kills annual grasses and most annual broadleaf weeds (excluding capeweed) in specifi ed situations and should not be used for any other purpose. Quickly kills green plant tissue on contact. Is immediately inactivated in the soil. At spraying, weeds should be growing vigorously and must not be covered with soil or heavy dew. The principle of selective weed control with this product is that annual weeds are killed but perennial plants and clovers recover after an initial scorch. The control of annual weeds by spraying with this product will allow the desirable perennial species to thicken up at the expense of the weeds. Moisture and fertility should not be limiting at spraying and the proportion of desirable species must be great enough for them to fi ll in the areas previously occupied by weeds. Long term weed control can be obtained following the quick knockdown given by this product if it is combined with soil residual chemicals.

 

DO NOT use hand-held ultra low volume controlled droplet applicators (CDA units), boomless jets or misting-machines.

 

Protection of wildlife, fish, crustaceans and environment 

DO NOT contaminate streams, rivers or waterways with the chemical or used containers. This formulation should not be applied on or near water which is used for human consumption, livestock watering or irrigation purposes or water used for commercial or recreational fishing.

 

Protection of crop, native and other non-target plants

DO NOT apply under weather conditions or from spraying equipment that may cause spray to drift onto susceptible plants/crops, cropping lands or pastures. This formulation should not be applied on or near water which is used for irrigation purposes.

 

Safety Directions

 

Very dangerous, particularly the concentrate. Product is poisonous if swallowed. Will irritate the nose, throat and skin. Attacks eyes. Protect eyes while using. Avoid contact with eyes, skin and clothing. When opening the container and preparing for use, wear elbow-length PVC gloves, face shield or goggles. If product on skin, immediately wash area with soap and water. If clothing becomes contaminated with product, remove clothing immediately. If product in eyes, wash it out immediately with water. Avoid contact with spray mist. DO NOT inhale spray mist. After use and before eating, drinking or smoking, wash hands, arms and face thoroughly with soap and water. After each day's use, wash gloves and face shield or goggles and contaminated clothing.

 

Storage

Store in the closed, original container in a cool, well-ventilated area. DO NOT store for prolonged periods in direct sunlight.

 

Envirodrum Micro Matic Valve (110 L)

Store the original sealed Envirodrum in a cool well-ventilated area. DO NOT store for prolonged periods in direct sunlight. DO NOT tamper with the Micro Matic valve or the security seal. DO NOT contaminate the Envirodrum with water or any foreign matter.

 

Disposal

Triple or preferably pressure rinse containers before disposal. Add rinsings to spray tank. DO NOT dispose of undiluted chemicals on-site. If recycling, replace cap and return clean containers to recycler or designated collection point (contact drumMuster Collection agency or Local Council for collection sites). If not recycling, break, crush, or puncture and bury empty containers in a local authority landfill. If no landfill is available, bury the containers below 500 mm in a disposal pit specifically marked and set up for this purpose clear of waterways, desirable vegetation and tree roots. Empty containers and product should not be bur

nt.

For refillable containers, empty contents fully into application equipment. Close all valves and return to point of supply for refill or storage.

After each use of the product, ensure that the Micro Matic coupler delivery system and hoses are disconnected, triple rinsed with clean water and drained accordingly. When the contents of the Envirodrum have been used, return Envirodrum to the point of purchase. The Envirodrum remains the property of Cheminova Pty. Ltd.
