Overview: A non-selective herbicide for the control of many annual and perennial weeds. 

  SDS (108 KB)

  Label  (209 KB)

FMC Glyder Offense 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. FMC Glyder Offense 540 may be used for weed control on agricultural land prior to sowing any edible or non-edible crop but not prior to transplanting tomato seedlings. 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. FMC Glyder Offense 540 is absorbed by plant foliage and green stems. It is inactivated in the soil and does not provide residual weed control. FMC Glyder Offense 540 moves through 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.


General Instructions




DO NOT disturb weeds by cultivation, sowing or grazing for six hours of daylight following treatment

of annual weeds and seven days for perennial weeds to ensure herbicide absorption, unless

specified otherwise in critical conditions.


Withholding Periods




Resistance Weed Warnings


FMC Glyder Offense 540 is a member of the Glycines group of herbicides. FMC Glyder Offense 540 has the inhibition of EPSP synthase mode of action. For weed resistance management, FMC Glyder Offense 540 is a Group M Herbicide. Some naturally occurring weed biotypes resistant to FMC Glyder Offense 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 FMC Glyder Offense 540 or other Group M herbicides. Since the occurrence of resistant weeds is difficult to detect prior to use, FMC Crop Protection Pty Ltd accepts no liability for any losses that may result from the failure of FMC Glyder Offense 540 to control resistant weeds.


Crop Establishment


FMC Glyder Offense 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.




FMC Glyder Offense 540 mixes readily with water. Reduced results may occur if water is used containing suspended clay or organic matter e.g. from dams, streams or 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 rinsed with clean water following application. Ensure that the sprayer is free of any residues of previous spray materials 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 ó full with clean water and start agitation.

2. Where ammonium sulphate is recommended, add liquid Spraymate Liase at 2L/100L spray solution and mix thoroughly.

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

4. Add FMC Glyder Offense 540 and the remaining water. Mix thoroughly.

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

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


Clean all equipment after use by washing thoroughly with clean water.


Tank Mixtures


FMC Glyder Offense 540 may be tank-mixed with the following herbicides, insecticides and adjuvants. 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 of 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/spraying is occurring.


Tank Mixtures – Herbicides

2,4-D ester, 2,4-D IPA, atrazine flowable or granular, carfentrazone, chlorsulfuron, dicamba, imazapic, LVE MCPA, metsulfuron-methyl oryzalin/trifluralin, oxyfluorfen, pendimethalin, simazine flowable or granular, sulfometuron methyl, triasulfuron, tri-allate, triclopyr, tribenuron. The addition of oxyfluorfen at 75mL/has to recommended rates of FMC Glyder Offense 540 prior to planting winter cereals will improve the 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 – 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 – Spraymate Liase (Ammonium Sulphate)

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




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 80L/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 FMC Glyder Offense 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 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. 

RATE: Mix 700mL FMC Glyder Offense 540 with 2.3 litres clean water. Adjust flow rate to suit equipment.


Aerial Equipment

FMC Glyder Offense 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 to sorghum and cotton crops up to a maximum rate of 2.7L/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 and using settings to produce a median droplet diameter of 250-350 microns. Swath width should be set to take into account aircraft type, wind conditions and target height. Swath width will need to be reduced to avoid stripping under light wind conditions and/or application to tall, dense targets e.g. pre-harvest application, treatments in heavy crop stubble. Thoroughly wash aircraft, especially landing gear, after each day of spraying to remove herbicide residues.


Application on hilly terrain

Increase water volume to 30-80L/ha and increase droplet diameter of output to at least 300 microns to optimise deposition of spray output onto weeds.

Air temperature and relative humidity

DO NOT apply FMC Glyder Offense 540 by aircraft at temperatures above 30 deg C. Increase water volume output to at least 30L/ha when temperatures rise above 25 deg C. 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 winds (less than 4km/h) or inversion conditions or where wind speeds exceed 12km/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 surfactants, adjuvants or other pesticides except as specifically directed on this label.

  • Rain within 1 hour of 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 browning 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 regrowth to 6-8cm before spraying and use the higher rates recommended.


Protection of Crops, Native and other Non-Target Plants


Avoid contact with foliage, green bark or stems, canes, laterals, suckers, fresh wounds, exposed non-woody roots, flowers or fruit of crops, desirable plants and trees, since sever injury or destruction may result.

DO NOT apply under weather conditions, or from spraying equipment, that may cause spray to drift

onto nearby susceptible plants/crops, cropping lands or pastures.


Protection of Wildlife, Fish, Crustaceans and Environment


DO NOT contaminate dams, rivers or streams with the product or used container. DO NOT apply to weeds growing in or over water. DO NOT spray across open bodies of water.


Storage and Disposal


Store in the closed, original container in a cool, well-ventilated area. Do not store for prolonged periods in direct sunlight. Do not contaminate seed, feed or foodstuff. Do not re-use container for any purpose. 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 containers in a local authority landfill. If no landfill is available bury the containers below 500mm 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.


For REFILLABLE containers: Empty contents fully into application equipment. Close all valves and return to point of supply for refill or storage.


Safety Directions


Will irritate the eyes. May irritate the nose and throat. Repeated exposure may cause allergic disorders. Avoid contact with eyes and skin. When opening the container, preparing spray and using the prepared spray, wear cotton overalls buttoned to the neck and wrist or equivalent clothing, elbow length PVC or nitrile gloves and face shield or goggles. If product in eyes, wash it out immediately with water. Wash hands after use. After each day’s use, wash gloves, face shield or goggles and contaminated clothing.
