GENERAL INSTRUCTIONS

Roundup Biactive is a non-volatile, water-soluble liquid product with non-selective herbicidal activity against many annual and perennial broadleaf weeds and grasses.

Roundup Biactive may be used for weed control in agricultural land prior to sowing any edible or non-edible crop, but not prior to transplanting tomato seedlings.

Roundup Biactive is absorbed by plant foliage and green stems. It is inactivated immediately in the soil and does not provide residual weed control. Roundup Biactive moves through the plant from the point of contact to and into the root system.

Visible effects on annual weeds take 3-7 days but on perennial weeds may not be obvious for 2-3 weeks or longer in some cases. Visible effects of control may be delayed by cool or cloudy weather at and following treatment.

When applying this product prior to transplanting crops into plastic mulch, care must be taken to remove residues of this product from the plastic prior to transplanting. Residues can be removed by 2cm of natural rainfall or by applying water via a sprinkler irrigation system.

MIXING

Roundup Biactive mixes readily with water. Note: Reduced results may occur if water containing soil is used, e.g., water from ponds and unlined ditches, or if hard water containing calcium salts is used.

DO NOT mix, store, or apply this product or spray solutions of this product in galvanized steel or unlined steel containers or spray tanks, since a highly flammable gas mixture may be formed. Use stainless steel, brass, copper, fiberglass, plastic, or plastic-lined containers or spray tanks. Aluminium is susceptible to corrosion by Roundup Biactive and should not be used.

Ensure the spray tank is free of any residue or previous spray materials. Use spray solutions promptly and certainly within 5 days, since a gradual loss of activity will occur.

Spray tanks, pumps, lines, and nozzles should be thoroughly rinsed with clean water following application to prevent corrosion.

TANK MIXTURES/COMPATIBILITY

Roundup Biactive may be tank-mixed with the following herbicides, insecticides, and additives.

Read and follow all label directions, restraints, plant-back periods, withholding periods, regional use restrictions, and safety directions for the tank mix products.

MIXING INSTRUCTIONS FOR ALL TANK MIXTURES

1. Fill the spray tank 1/3 to 1/2 full with clean water and start agitation.

2. Where crystalline ammonium sulfate is recommended, wash 2% w/v (2kg/100L spray solution) through a top mesh-screen into the tank and mix thoroughly.

3. Add recommended herbicide/insecticide/additive to the spray tank and mix thoroughly.

4. Add Roundup Biactive and the remaining water. Mix thoroughly.

5. Add surfactant, if required, near the end of the filling process to minimize foaming.

6. Always maintain adequate agitation during application and use the tank mix promptly.

TANK MIXTURES – HERBICIDES

Atrazine flowable (Agricultural uses only DO NOT apply the tank mix for Barnyard grass control.), 2,4-D ester, dicamba, Glean, Simazine flowable, Oust, Yield, Stomp 330, Ally, Logran 750G, L.V.E. MCPA, and Striker.

The addition of Striker at 75 mL/ha to recommended rates of Roundup Biactive prior to planting wheat or barley will improve knockdown and increase the speed at which treated weeds develop visible signs of phytotoxicity.

Add crystalline ammonium sulfate as per directions below.

TANK MIXTURES - ADDITIVES

Crystalline Ammonium Sulphate RATE: 2% w/v (2kg/100L spray solution). (DO NOT apply the tank mix for Barnyard grass control). The addition of crystalline ammonium sulfate to Roundup Biactive, when used to control ANNUAL weeds, MAY improve the performance of Roundup Biactive under adverse environmental conditions such as cool, cloudy weather, and assist in minimizing the antagonism in tank mixes of Roundup Biactive and flowable triazine herbicides. Use only crystalline ammonium sulfate, NOT prilled or granulated forms. Ammonium sulfate may be corrosive to metal parts of the sprayer. Thoroughly flush tanks, pumps, and nozzles with water after use.

Pulse Penetrant RATE: 200mL/100L spray solution. Add when treating bracken (boom application), Gorse, Eucalypt suckers, and Lantana.

Wetter TX Surfactant RATE: 200mL/100L spray solution. Add when treating Annual ryegrass in Spring (from beginning August to end October). Wetter TX is not a general-purpose surfactant and should be used only where recommended.

Tank Mixtures - Insecticides

This product is compatible with the following insecticides: Imidan, Le-mat and emulsifiable concentrates of dimethoate and fenitrothion. Other insecticides have not been tested.

APPLICATION

Roundup Biactive is a non-selective translocated herbicide. Direct spray contact, or even slight drift, may cause severe injury or destruction of any growing crop or other desirable plants including trees. Clean all equipment after use by thoroughly washing with water.

BOOM EQUIPMENT

Use recommended rates of Roundup Biactive in 75 to 200 liters of clean water per hectare. When using Roundup Biactive at 500mL-1.5L/ha spray volumes in the range 25-100L/ha are preferred. Fan nozzle equipment is recommended, using pressures in the range 240-280kPa. Boom height must be set to ensure double overlap of nozzle patterns at the top of the weed canopy.

High Volume Application (eg. Knapsack/Handgun Equipment) The dilution rate is given as vol/1 liter eg: 10mL Roundup Biactive per liter of water. This is equal to 150mL Roundup Biactive per 15 liters of water or 1 liter per 100 liters of water. Adjust equipment to achieve an even spray pattern. Apply to ensure complete and uniform wetting of all foliage. For handgun equipment, a D6 spray tip (Spraying Systems Australia P/L) or equivalent, and an operating pressure of 400-700kPa are recommended.

Low Volume Application (eg. Gas Gun or Splatter Gun) Apply as an even spray to cover all foliage. Refer to Weeds Controlled for the dilution and volume of mixture to be applied. The dilution is specified as "Low volume mixture, Roundup Biactive:Water''. For example, a 1:9 mixture equals one part Roundup Biactive plus 9 parts water.

Wiper Equipment

Wiper Equipment (eg. ropewick, canvas, felt, or carpet applicators) may be used to apply Roundup Biactive onto weeds growing in oilseed crops, sugarcane, cotton, seed and pod vegetables, tree and vine crops specified in this label, pasture and non-crop areas. Avoid contact with desirable vegetation.

• Operate wiper equipment a minimum of 10cm above the crop or pasture. Weeds should be at least 15cm above the crop or pasture at the time of application. Speed of travel should be no greater than 8km/h, Best results are achieved at lower speeds and where two applications are made in opposite directions (double pass).

• Where weeds are of variable height, or occur in dense infestations or clumps, some plants may not be contacted by the herbicide solution. In these cases, repeat treatment may be necessary.

• Mix only enough herbicide solution for immediate requirements. DO NOT store mixed solution for more than a few days. Flush out equipment with water after use.

• RATE: Mix 1 liter Roundup Biactive with 2 liters clean water to prepare a 33% solution.

• Roundup Biactive may be used according to the above directions for suppression or control of many annual and perennial weeds.

• See Weeds Controlled tables for specific use recommendations.
