  • The reliability that you'd expect from the original Select brand
  • Stronger formulation so you carry and handle less product
  • Safe for use on a wide range of broadleaf crops
  • Many tank mix options for broad spectrum of control

General Instructions


Resistant Weeds Warning


Arysta Select Xtra Herbicide is a member of the cyclohexanedione group of herbicides. Arysta Select Xtra Herbicide has the inhibition of acetyl coA carboxylase mode of action. For weed resistance management, Select Xtra Herbicide is a Group A Herbicide. Some naturally-occurring weed biotypes resistant to Arysta Select Xtra Herbicide and other Group A 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 Select Xtra Herbicide or other Group A Herbicides. Since occurrence of resistant individuals is difficult to detect prior to use, Arysta LifeScience Corporation accepts no liability for any losses that may result from the failure of Arysta Select Xtra Herbicide to control resistant weeds.


Cleaning Spray Equipment


Before using Arysta Select Xtra

Ensure that the recommended clean-out procedure for the previous product (particularly sulfonylurea herbicides) sprayed with the equipment was done properly.


After using Arysta Select Xtra

Empty the tank and drain the whole system.

Thoroughly wash inside the tank using a pressure hose, drain the tank and clean all filters in the tank, pump line and nozzles.

Use of a household detergent will aid in cleaning the equipment. Add detergent to the part-filled spray tank and thoroughly circulate through pumps, hoses and nozzles. Drain the system and thoroughly rinse twice with clean water.

Rinse water should be discharged onto a designated disposal area, or if this is unavailable, onto unused land away from desirable plants and water sources.




To ensure even mixing, half-fill the spray tank with clean water and add the required amount of product. Add spray additive and agitate thoroughly, then add the remainder of the water. Agitate again before spraying commences.




Ground Application:

Arysta Select Xtra Herbicide should be applied with calibrated spray equipment producing a median droplet range of 200 to 300 microns VMD. Apply in a minimum of 50 litres of water per hectare. Use 150 L/ha when spraying dense populations.


Aerial Application:

Arysta Select Xtra Herbicide can be applied through aircraft fitted with boom or Micronair equipment. A spray volume of 20 to 30 L/ha is recommended and equipment should be adjusted to deliver droplets in the range of 200 to 250 microns VMD. Best results will be obtained when aerial applications are made in a light crosswind. Applications should not be made during temperature inversions or in conditions of very low relative humidity. Care should be taken to avoid drift damage to adjoining grass crops.


Use of Select Xtra on pasture legume (Lucerne, Clover and Medic) seed crops and pastures and pasture herbs:

Arysta Select Xtra Herbicide has been demonstrated to be safe when applied to the following cultivars during early establishment


Pasture legumes:


Clover (Trifolium spp.)

Annual: Subterranean clover (Dalkeith, Dalsa, Goulburn, Koala, Nungarrin, Riverina, Seaton Park and York A), Arrowleaf clover (Zulu II), Balansa clover (Enduromax, Frontier, Paradana), Berseem clover (Elite II),Gland clover (Prima), Persian clover (Prolific, Leeton), Rose clover (Hylon)

Perennial: Strawberry clover (Palestine), White clover (NuSiral)


Lucerne and medics (Medicago spp.)

Lucerne (Aurora, Field, Genesis, Hunterfield, Multileaf, Salado, Sardi SEVEN, Sceptre and Venus), Barrel medic (Sephi, Jester Paraggio, Caliph), Burr medic (Scimitar, Santiago), Snail medic (Silver)


Serradella (Ornithopus spp.)

French or Pink serradella (Cadiz), Yellow serradella (Charano, Santorini)


Pasture herbs:


Chicory (Puna II) and Plantain (Tonic)

Apply Arysta Select Xtra  when plants have reached 2 - 4 trifoliate leaf stage, or after 40 days from sowing. Some pasture varieties may exhibit an initial reduction in crop vigour or biomass, however, these symptoms are transient and crops recover fully with no effect on yield.



Arysta Select Xtra Herbicide is compatible with the following grass herbicides: Targa*, Fusilade*, Verdict*, Sertin* and Correct*. (Refer to the Bayer Correct label for detail on adjuvant recommendations for that product).


NOTE: In all situations where Arysta Select Xtra Herbicide is mixed with another grass herbicide, Arysta Select Xtra Herbicide should be used at the full label rate specified for the target weed species. Arysta Select Xtra Herbicide may also be applied in tank mixtures with one of the following products: Sumi-Alpha1 50 EC, Sumi-Alpha1 Dual, Fastac* 100 and Le-Mat*.

Arysta Select Xtra Herbicide should not be applied in a tank mix with Brodal*, Basagran* or Blazer*. Apply as separate applications. For information on compatibility of products not listed, please refer to Arysta LifeScience Corporation.




DO NOT apply without the addition of an adjuvant.


DO NOT apply to plants that are stressed by moisture or temperature extremes.


DO NOT apply if rain is expected within one hour of application.


DO NOT apply Arysta Select Xtra Herbicide more than once to any one crop.


Protection of wildlife, fish, crustaceans and environment

Arysta Select Xtra Herbicide should not be applied through misting equipment or any other method likely to cause excessive drift. Care should be taken to avoid damage to adjoining native grasses or grass crops.


Safety Directions


Harmful if swallowed. Will irritate the eyes and skin. When preparing spray and using the prepared spray, wear cotton overalls buttoned to the neck and wrist, washable hat, elbow-length PVC gloves and face shield or goggles. If product in eyes, wash it out immediately with water. 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, face shield or goggles and contaminated clothing.



Store in the closed, original container in a dry, cool well ventilated area out of direct sunlight. Protect from frost.



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. If not recycling, break, crush or puncture and bury empty containers in a local authority landfill. If not 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 burnt.





Ornamentals and Trees - While Arysta Select Xtra Herbicide is generally selective to broadleaved plants (i.e. it is active against grasses), tests should always be made on a small number of plants not previously tested.


DO NOT use on Gymnosperms (pines, conifers, etc) unless a prior test has been conducted to check safety on the relevant species.
