Dual Gold Herbicide (S-Metolachlor) DUAL-GOLD Syngenta

Description

Dual Gold Herbicide

Active Ingredient: S-Metolachlor @ 960g/L

Similar or Comparable to Metolamax Gold Herbicide (Conquest) & Left Hook Herbicide (Apparent)

Dual Gold Herbicide is a short residual, pre-emergent herbicide for the control of many important annual grasses and broadleaf weeds in the crops nominated.

Under optimal conditions, Dual Gold Herbicide provides residual control of weeds for up to 8 weeks. This ensures optimum crop establishment and development.  The new shoots (coleoptile) of germinating weeds absorb Dual Gold Herbicide during emergence. Once absorbed, the active constituent, S-metolachlor, controls weeds by producing a severe growth inhibition of seedling-shoot and root tissue soon after germination. Its effectiveness depends on the occurrence of rainfall or irrigation to move it down into the top 3 to 4 cm of soil where it must be present in a moist soil at the time of weed germination

In most cropping situations, Dual Gold Herbicide can be applied before, at or immediately after planting before annual weeds and crops emerge. Dual Gold Herbicide does not have to be mechanically incorporated into the soil, making it suitable for use in conservation tillage systems however, better results are usually observed where incorporation by rainfall, irrigation or mechanical means occurs within 10 days of application.

Dual Gold Herbicide is a short residual, pre-emergent herbicide for the control of many important annual grasses and broadleaf weeds in the crops nominated. The product does not control the important broadleaf weeds in maize, sweet corn and Concep II treated sorghum but, when mixed with Flowable Atrazine, control of many important annual weeds and grasses is obtained without the problem of carryover of herbicides affecting succeeding crops.  The product acts mainly through shoot (coleoptile) absorption. Its effectiveness depends on the occurrence of rainfall or irrigation to move it down into the top 3 to 4 cm of soil, where it must be present at the time of weed germination.

What crops and situations can Dual Gold Herbicide be used in;

Barley Cocksfoot Maral Persian Clover Pasture Phalaris Pasture Sweet Corn

Questions and answers from customers

    Can Dual Gold Herbicide be sprayed on couch grass?

  1. Q Can Dual Gold Herbicide be sprayed on couch grass?
    Asked by Shane Wogand on July 6, 2022 3:59 pm
    Answered by the admin

    Dual Gold Herbicide is only registered for use in certain cropping situations for grass and broadleaf weed control and does not have a turf registration.  Meteor Herbicide is registered for pre-emergent weed control on many varieties, including couch.  Meteor Herbicide is made from Metolachlor @ 960g/L, as is Dual Gold.  Specialist Sales are bound by what the product is legally registered for use on, so we don't recommend you use Dual Gold Herbicide in turf situations.

Application:

  • Do not apply by aircraft
  • Warning — cotton: Heavy rain following an application of Dual Gold Herbicide, together with below average soil temperatures, can result in crop injury, due to the inability of the germinating plant being able to metabolise the herbicide.

On these soil types, use rates of Dual Gold Herbicide towards the lower end of the rate range and apply onto moist soil. Irrigation after application should be limited to no more than 25 mm. 
  • Zero-tillage (canola, barley, oats, wheat. Triticale): when sowing using knife points and zero-tillage and leaving a seeding slot.
  • Do not apply post-seeding unless harrows (or similar) have tilled-in the seeding slot before application.
