PRODUCT INFORMATION

Roundup Prime is a non-volatile, non-selective, water-soluble liquid herbicide designed for controlling both annual and perennial grasses and broadleaf weeds. It is suitable for a wide range of applications in both agricultural and non-agricultural settings. While it can be used for weed control on agricultural land prior to planting any edible or non-edible crop, it should not be used before transplanting tomatoes. Care must be taken to remove residues from plastic before transplanting by using 20mm of natural rainfall or applying water via a sprinkler irrigation system.

The herbicide is absorbed by plant foliage and green stems, and it is inactivated on clay and organic matter in soil, providing no residual weed control. It moves throughout the plant from the point of contact to the root system. Initial visible effects on annual weeds take 3-7 days but may not be noticeable for 2 to 3 weeks under cool, cloudy conditions or on some perennial weeds.

CROP ESTABLISHMENT

Roundup® Prime is recommended for controlling emerged weeds before crop establishment. Cultivation and/or planting operations that provide suitable conditions for crop emergence and establishment are required following herbicide application. In cases of heavy weed growth or unsuitable soil conditions, planting should be delayed to allow for weed decay or the development of more favorable soil conditions. Incorporating green or decaying vegetation may retard crop emergence under cold, wet conditions. Grazing and cultivation to leave trash on the surface can reduce vegetation.

MIXING

Roundup® Prime readily mixes with water. Reduced results may occur if water contains suspended clay or organic matter from dams, streams, and irrigation channels, or if it has high levels of calcium, magnesium, or bicarbonate ions. It should not be mixed, stored, or applied in galvanized steel or unlined steel containers or spray tanks, as this may form a highly flammable gas mixture. Stainless steel, aluminum, brass, copper, fiberglass, plastic, or plastic-lined containers or spray tanks are recommended. Spray tanks, pumps, lines, and nozzles should be thoroughly cleaned with clean water after application. Ensure that the spray tank is free of any residue from other spray solutions prior to mixing. Use spray solutions promptly, as a gradual loss of activity may occur over days following spray preparation.

Mixing Instructions:

1. Fill the spray tank 1/3 to 1/2 full with clean water and start agitation.
2. If adding Liase (ammonium sulfate), use a 2% v/v and mix thoroughly.
3. If tank-mixing, add the recommended herbicide/insecticide/additive to the spray tank and mix thoroughly.
4. Add Roundup Prime and the remaining water. Mix thoroughly.
5. Add Pulse Penetrant or Wetter TX, if required, near the end of the filling process.
6. Always maintain adequate agitation during application and use the tank mix promptly.

Clean all equipment after use by washing thoroughly with water.

TANK MIXTURES

Roundup® Prime may be tank-mixed with various herbicides, insecticides, and adjuvants. It is essential to read and follow all label directions, restraints, plantback and withholding periods, and safety directions for the tank-mix products. In multiple product tank mixes, a minimum water volume of 50L/ha is recommended, and local advice should be sought. Correct mixing order is crucial, and good in-tank agitation during application/spraying is necessary.

Tank Mixtures – Herbicides:

• Nufarm Estercide 800, Nufarm Estercide Xtra 680, Nufarm LV Estercide 600 (2,4 – D ester), Surpass 475, Ally*, Associate, Affinity*, Hammer*, Nu-trazine 600, Nu-trazine 900 DF, Avadex Xtra, Flowable Simazine, Nufarm Simazine 900 DF (simazine flowable or granular), Nufarm Kamba 500 (dicamba), Express*, Eclipse*, Flame*, Flandor*, Garlon* 600, Invader, Glean*, Lusta, Striker, Logran* 750WG, Nugran, Logran B Power (ensure fully dispersed prior to the addition of Roundup Prime), Archer, Lontrel, Nufarm LVE MCPA (MCPA LVE), MONZA, Oust*, Rifle, Comet 400, Starane 200, Stomp*, Surflan, Triflur Xcel (trifluralin), and Yield*. Other brands have not been tested.
• The addition of Striker at 75mL/ha to recommended rates of Roundup Prime before planting Winter cereals will improve knockdown of certain weeds.

Tank Mixtures – Insecticides:

• This product is compatible with the following insecticides: Imidan*, Le-Mat*, Lorsban* 500, Perfekthion* EC 400, Pirate* 300, Karate*, Sumithion ULV, Talstar*, and emulsifiable concentrates of dimethoate and fenitrothion. Other insecticides have not been tested.

Adjuvants – Nufarm LI700® Surfactant:

• At rates of 300mL – 500mL per 100L, LI700 may modify the droplet spectrum produced by CP and flat fan nozzles, reducing the proportion of FINE droplets produced by these nozzles.

Adjuvants – Wetter TX:

• Wetter TX is recommended for the control of silver grass and annual ryegrass in late Winter and Spring. Wetter TX is not a general-purpose surfactant and should only be used where recommended.
• Rate: 200mL/100L spray solution.

Adjuvants – Pulse Penetrant:

• Pulse Penetrant is recommended for the control of Bracken and many woody weeds.
• Rate: 200mL/100L spray solution.

Adjuvants – Nufarm Liase (Ammonium sulfate):

• Liase may be used as an adjuvant to alleviate the adverse effects of high levels of calcium, magnesium, and bicarbonate ions in water.
• Rate: 2L/100L spray solution.

APPLICATION

Boom Equipment (Broadacre):

• For boom application, a spray volume of 80L/ha or less is recommended for broadacre uses and 200L/ha or less for treeline and vineline spraying in orchards and vineyards.
• Glyphosate works better when present at a higher concentration in the spray solution provided sufficient coverage of the target is achieved.
• Nozzles and pressure settings should deliver a COARSE to VERY COARSE spray quality (as defined by ASAE S572) at the target.
• The use of nozzles and/or pressure settings that produce VERY FINE or FINE spray quality should be avoided.
• In multiple product tank mixes, a minimum water volume of 50L/ha is recommended, and local advice should be sought.
• Correct mixing order is important, as is good in-tank agitation when application is occurring.

Shielded Applications:

• A spray volume of 80L/sprayed ha is recommended for shielded applications, using nozzle types and pressure settings to deliver a COARSE ASAE S572 spray quality at the target.
• Crop damage may result from spray drift due to incorrect nozzle and/or pressure selection, inadequate shielding and/or wind strength, high evaporation rates, or excessive ground speed.

High Volume Application (e.g., Knapsack, Handgun Equipment):

• The dilution rate varies depending on the use situation and weeds controlled. Adjust equipment to achieve an even spray pattern with a COURSE spray quality at the target.
• Apply to ensure complete and uniform wetting of all foliage.
