PRODUCT INFORMATION MAX OUT 540 is a non-volatile, non-selective, water-soluble liquid herbicide for the control of annual and perennial grasses and broadleaf weeds in a wide range of agricultural and non-agricultural use situations.

MAX OUT 540 may be used for weed control on agricultural land prior to planting any edible or non-edible crop but not prior to transplanting tomatoes. 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 sprinkle irrigation system.

MAX OUT 540 is absorbed by plant foliage and green stems. It is inactivated on clay and organic matter in soil and does not provide residual weed control. MAX OUT 540 moves throughout the plant from the point of contact to and into 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.

RESISTANT WEEDS WARNING MAX OUT 540 is a member of the Glycines group of herbicides. MAX OUT 540 has the inhibition of EPSP synthase mode of action. For weed resistance management MAX OUT 540 is a Group M herbicide. Some naturally occurring weed biotypes resistant to MAX OUT 540 and other Group M 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 MAX OUT 540 or other Group M herbicides. Since the occurrence of resistant weeds is difficult to detect prior to use, Kenso accept no liability for any losses that may result from the failure of MAX OUT 540 to control resistant weeds.

CROP ESTABLISHMENT MAX OUT 540 is recommended for control of emerged weeds prior to crop establishment. Cultivation and/or planting operations which provide conditions suitable for crop emergence and establishment are required following herbicide application. Where heavy weed growth is present or soil conditions are unsuitable, planting should be delayed to allow for decay of weeds and/or development of more favourable soil conditions for the formation of a suitable seedbed. Incorporation of green or decaying vegetation may retard crop emergence under cold, wet conditions. Vegetation may be reduced by grazing and weed decay may be assisted by cultivation to leave trash on the surface.

MIXING MAX OUT 540 mixes readily with water. Reduced results may occur if water is used containing; suspended clay or organic matter e.g. from dams, streams and irrigation channels, or high levels of calcium, magnesium or bicarbonate ions. Do not mix, store or apply this product in galvanised steel or unlined steel containers or spray tanks, since a highly flammable gas mixture may be formed. Use stainless steel, aluminium, brass, copper, fibreglass, plastic or plastic lined containers or spray tanks. Spray tanks, pumps, lines and nozzles should be thoroughly cleaned with clean water following application. Ensure that the spray tank is free of any residues of other spray solutions prior to mixing. Use spray solutions promptly as a gradual loss of activity may occur over a period of 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 ammonium sulphate, use a 2% v/v and mix thoroughly.

3. If tank-mixing, add recommended herbicide/insecticide/additive to the spray tank and mix thoroughly.

4. Add MAX OUT 540 and the remaining water. Mix thoroughly.

5. Add Silken Penetrant, 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.

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

Adjuvants – Ammonium Sulphate (Ammo-Flo Herbicide Adjuvant) Ammo-Flo Herbicide Adjuvant 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 For boom application, a spray volume of 80L/ha or less is recommended for optimum performance. Nozzles and pressure settings should be selected to deliver a MEDIUM or MEDIUM – COARSE size droplet at the target (BCPC – British Crop Protection Council Standard). The use of nozzles and/or pressure settings that produce VERY FINE or FINE droplets should be avoided as these are prone to loss or drift. 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.

For shielded applications a spray volume of 80 L/sprayed ha is recommended using nozzle types and pressure settings to deliver a COARSE (BCPC) size droplet at the target. Crop damage may result if spray drift occurs through incorrect nozzle and /or pressure selection, inadequate shielding and/or wind strength, high evaporation rates or excessive ground speed.

Wiper Equipment Wiper equipment (e.g. Ropewick, canvas, felt or carpet applicators) may be used to apply MAX OUT 540. 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/ha. 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. Rate: Mix 700 mL MAX OUT 540 with 2.3 litres clean water. Adjust flow rate to suit equipment.

Aerial Equipment MAX OUT 540 may be applied by aircraft for control of weeds in forests, cropland or pasture prior to establishment of crops, new pastures or new forest plantings and for pre-harvest applications, up to maximum rate of 2.7 L/ha where specified by this label. DO NOT apply treatments by aircraft in situations where drift onto sensitive crops and pastures is likely to occur.

Apply treatments using boom or Micronair equipment using a spray volume not less than 20L/ha using settings to produce a median droplet diameter of 250-350 microns. 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. Swatch width should be set to take into account aircraft type, wind conditions and target height. Swatch width will need to be reduced to avoid striping under light wind conditions and/or application to tall, dense targets e.g. pre-harvest application, treatments in heavy crop stubble. Thoroughly wash aircraft after each day of spraying to remove herbicide residues.

Application on hilly terrain Increase water volume to 30-80L/ha and increase median droplet diameter of output to at least 300 microns to optimize deposition of spray output onto weeds.

Air temperature and relative humidity DO NOT apply MAX OUT 540 by aircraft at temperatures above 30ºC. Increase spray output to at least 30L/ha when temperatures rise above 25ºC. Avoid application when relative humidity falls below 35%.

AVOID DRIFT DO NOT apply treatments with spraying equipment or under weather conditions which are likely to cause spray drift onto nearby susceptible crops, pastures or other sensitive plants. DO NOT apply treatments under very light (less than 4km/h) or inversion conditions or where wind speeds exceed 12 km/h).

APPLICATION CHECKLIST • Do not treat weeds under poor growing conditions due to moisture stress, waterlogging, severe frosting, insect damage etc. Reduced performance may also occur where weeds are covered with dust or silt. • Do not add surfactant, adjuvants or other pesticides except as specifically directed on this label. • Do not spray if rainfall is imminent. Rainfall shortly after application which causes run off may require re-treatment. Rainfastness is reduced if weeds are not actively growing, under stress or conditions of low light intensity/darkness. The addition of *Wetter TX may improve rainfastness on Winter annual weeds. • A withholding period for grazing is not required. However, it is recommended that grazing of treated plants be delayed to ensure herbicide uptake. Certain plants such as Soursob, Variegated thistle, Sorghum and Johnson grass may be naturally toxic to stock when eaten in large quantities under certain conditions. Where plants are known to be toxic, grazing should be delayed until complete desiccation of treated plants has occurred. • Apply treatments to weeds which have at least one true leaf (broadleaf weeds) or two leaves (grasses) to provide an adequate surface area for herbicide uptake. • If heavy grazing has occurred, allow re-growth to 6-8 cm before spraying and use the higher rates recommended.
