General Instructions


FMC Glyder 450 Herbicide is a non-selective herbicide, which is effective against a wide range of annual and perennial broadleaf weeds and grasses. It is translocated throughout the plant where it kills both foliage and roots. Ideally the best time to use the product is when target species are in a state of active growth, moderate climatic conditions are present and plants are free of disease and dirt cover. The effects of the herbicide may not be visible for 3 - 7 days for annual weeds or 2 - 3 weeks for perennial weeds depending on water quality, weather conditions, weed species and rate used. While cool and cloudy conditions can sometimes delay the appearance of chemical activity, it can generally be expected that symptoms of chemical effect will appear 2 - 7 days after spraying annual species, and 2 - 3 weeks after spraying perennial species. The symptoms are demonstrated by a yellowing and accompanying wilting, progressing to a brownout.




DO NOT spray if rainfall is expected as rainfall within 6 hours of treatment may reduce the effectiveness of this product. Heavy rainfall within 2 hours of treatment may wash the product from the leaf surface and re-treatment may be necessary.

DO NOT disturb treated weeds by grazing, cultivation, sowing, etc after treatment for 1 day for annual weeds and 7 days for perennial weeds to ensure complete uptake of the herbicide.

DO NOT treat weeds under stress from frost, cold, waterlogging, lack of moisture or disease. Plants must be actively growing to ensure optimum uptake of the product.


Spray Preparation


1. Make sure the spray tank is clean and residues from previous spray usage have been removed.

2. Fill the spray tank 1/2 to 3/4 full with clean water. Where possible avoid turbid water or hard water containing calcium salts, as this may reduce weed control.

3. Where ammonium sulphate is recommended, wash 2% V/V (2 L/100 L spray solution) through a top mesh screen into the tank and mix thoroughly.

4. Add the appropriate amount of FMC Glyder 450 as per the Direction for Use tables.

5. Add surfactant (if required). Mix well keeping the filling hose below surface to avoid foaming.

6. Add water to fill vat.

7. Remove hose from tank as soon as full to prevent back siphoning.


DO NOT use mechanical agitators, as they cause excessive foaming.

DO NOT add non-approved herbicides and insecticides.

Use ONLY plastic, plastic lined, stainless steel, aluminium, copper, brass or fibreglass tanks. Galvanised

steel or unlined steel spray tanks can react with the product to produce hydrogen, which can form a

combustible gas mixture, which can be flashed by ignition sources.


Crop Establishment


FMC Glyder 450 Herbicide is recommended for the control of emerged weeds prior to crop establishment. Suitable cultivation and/or sowing procedures are required to provide seedbed conditions favourable for crop germination and development. Early spraying to control young weeds will favour preparation of suitable seedbeds. On friable soils, where there is only a light cover of young weeds, sowing may proceed 1 day after spraying. In situations of heavy weed growth, sowing should be delayed until weed decay and soil conditions allow formation of a suitable seedbed. Incorporation of green or decaying vegetation and roots into seedbeds by cultivation/sowing may cause retarded crop emergence especially in cold and/or wet conditions. Vegetation may be reduced by

grazing and/or cultivation but trash should be left on the surface. Avoid use of pre-emergence herbicides where label directions advise a risk of retarded crop emergence, and in marginal seedbed conditions pay particular attention to correct seeding depth.



The addition of surfactant may improve weed control where water rates are high or product rates low. Suggested surfactant rates at 200 mL/100 L of 1000 g/L non-ionic surfactant or 250 - 500 mL of 700 g/L surfactant. Do not add spraying oils, agricultural chemicals or other materials except as directed on the label.


Organosilicone Penetrant:

In certain situations such as for the control of brush and woody weeds (as indicated in the Directions for Use) weed control may be enhanced by the addition of an organosilicone penetrant at its label rate.


Rainfall Effects:

Heavy rainfall within 2 hours of spraying can mean that the chemical may be washed off the plant, with the result that the herbicide may not be totally effective. Re-spraying may be needed. Normal rainfall up to 6 hours after application may reduce effectiveness. Adequate results may not be achieved if the product is applied when weeds are stressed by conditions such as drought, water logging or frost.


Soil Persistence:

The product is not persistent in soils and is rapidly broken down by microbes present in the soil, as well as by hydrolysis caused by freestanding moisture or moisture that may be present in soil particles. Should residual activity be needed refer to the “Compatibility” section of this label.


Resistant Weeds Warning


FMC Glyder 450 Herbicide is a member of the glycine group of herbicides. FMC Glyder 450 Herbicide has the inhibitor of EPSP synthase mode of action. For weed resistance management FMC Glyder 450 Herbicide is a group “M” herbicide. Some naturally occurring weed biotypes resistant to FMC Glyder 450 Herbicide and other inhibitors of EPSP synthase 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 450 Herbicide or other inhibitors of EPSP synthase 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 450 Herbicide to control resistant weeds. DO NOT however assume resistance without first reviewing the method of application, timing, water quality and weather conditions.


Application Equipment


The following types of equipment may be used for applying the product: knapsack, wiper, handgun, aerial, boom.


For Knapsack and Handgun Equipment:

Maximum efficiency can be achieved by using D6 spray plate and applying at a pressure of 400 - 700 kPa. As the product is translocated through contact points on the plant, good coverage and uniform wetting is needed to maximise uptake by the plant. The dilution rate is given as volume per litre. Adjust

equipment to ensure even spray pattern.


For Boom Equipment:

Maximum efficiency can be achieved by using fan nozzles at a pressure of 240 - 280 kPa. Boom height should be adjusted to ensure double overlap of nozzle patterns at the top of the weed canopy. Water volumes of 75 to 200 L of clean water per hectare are recommended. When using rates of 500 mL to 1.5 L/ha, spray volumes in the range of 25 - 100 L/ha are preferred.


For Aerial Equipment:

For Micronair and boom equipment a droplet size of 250 - 350 micron diameter is recommended in a minimum spray volume of 20 L/ha. A swath width in the range of 15 - 17 m is most appropriate for this form of spraying. When using this form of application give consideration to the fact that the product is highly nonselective and if desirable plants, trees, etc are in the vicinity of the area to be sprayed, they could be affected by drift or targeted contact. This would limit usage via this technique to such situations as weed control on fallows or pasture; control prior to establishment of crops or pasture. In pasture establishment situations, it may also be necessary to spray hilly terrain and gullies in both directions to ensure good spray coverage of grass and broadleaf weeds and to avoid spray shielding effects from trees.


Hilly terrain:

As spraying height may vary on hilly terrain, to maximise target contact, increase the water volume to 30 - 80 L/ha and increase the droplet size to a minimum of 300 micron average size.

Note: In high temperatures and dry conditions evaporation of droplets prior to reaching target species can occur. It is important to increase water volume to at least 30 L/ha and average droplet size to 300 micron if temperatures are in excess of 25ÅãC.

DO NOT SPRAY if temperature is above 30ÅãC.


For Wiper Equipment:

Wiper equipment such as ropewick applicators can be used to apply this product to weeds growing in oilseed crops, sugarcane, cotton, seed and pod vegetables, tree and vine crops, pasture and non-crop areas specified on this label. Weeds should be at least 15 cm above the crop or pasture. Operate wiper

equipment a minimum of 10 cm above the crop or pasture. Speed of travel should be no greater than 8 km/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 clumps or in dense infestations some plants may not be contacted by the herbicide solution and re-treatment may be necessary. Mix only enough solution for immediate requirements. Do not store a mixed solution for more than a couple of days.


Rate: Mix 800 mL FMC Glyder 450 Herbicide with 2 L clean water to prepare a 33% solution. Refer to Weeds Controlled section of label for specific recommendations.


Sprayer Clean Up


After use, clean all spray equipment by thoroughly washing with clean water, or commercial spray equipment cleaner, in order to prevent corrosion to tanks, lines and nozzles. Aircraft used in application should be thoroughly washed with particular attention to wheels and landing gear.




It has been established that a wide range of products may be tank mixed with glyphosate. The following products may be mixed with glyphosate to broaden the spectrum of weeds controlled, add soil residual activity, and improve performance. Refer to the Directions for Use section for detailed information on

tank mix situations.


Additives: Liquid ammonium sulphate (2 L/100 L) can be used to minimise antagonism when mixed with flowable triazine herbicides; and help minimise the adverse effects of water quality problems, such as high pH and mineral content, that are common in creek and bore water, that can be antagonistic with

glyphosate herbicide.


Herbicides: Atrazine - flowable or granular (see Additives above - do not apply the tank mix for control of Barnyard Grass (Echinochloa crus-galli)), dicamba, 2,4-D ester, chlorsulfuron, metsulfuron, Yield*, Stomp*, LVE MCPA, Goal CT*, simazine flowable.


Goal CT: The addition of Goal CT Herbicide at 75 mL/ha to recommended rates of this product prior to planting wheat or barley will improve knockdown and increase the speed at which treated weeds develop visible symptoms of phytotoxicity. Add Flowright Compatibility agent to improve the compatibility in cold water (less than 15ÅãC). See directions below.


Insecticides: chlorpyrifos, dimethoate, fenitrothion, Gusathion*, Imidan*, Le-Mat*, Lorsban*, metasystox, Sumithion*, Perfekthion* EC 400.


Flowright Compatibility Agent

Rate: 200 mL/100 L spray solution. When mixing with Goal CT*, add to improve the compatibility in cold water (less than 15ÅãC). Flowright must be pre-mixed with Goal CT* before adding to the spray tank. Refer to Flowright label for directions.


Protection of Crops, Native and other Non-Target Plants


DO NOT apply under meteorological conditions or from spraying equipment that could be expected to cause spray drift onto nearby susceptible plants, adjacent crops, crop lands or pastures, private properties or public lands. DO NOT apply prior to transplanting tomato seedlings.


Protection of Wildlife, Fish, Crustaceans and Environment


DO NOT contaminate dams, rivers or streams with the product or used container. When controlling weeds near water, refer to label directions to minimise the entry of spray into the water.


Protection of Livestock


There is no withholding period for grazing stock, but to give the product a chance to be efficiently absorbed by sprayed vegetation, it is recommended that livestock be kept clear of treated annual weeds for 1 day after spraying, and for perennial weeds 7 days. For certain plants known to be toxic to stock, it is advisable to keep livestock away until complete browning occurs.


Storage and Disposal


Do not store the product in galvanised steel or unlined steel containers, as the product may react to produce hydrogen gas, which in turn could form a highly combustible gas that could explode if ignited by an open flame, or spark, lighted cigarette, etc. Store in the closed original container in a cool, well-ventilated area. Do not store for prolonged periods in direct sunlight.


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 empty containers in a local authority landfill. If no land fill is available, bury the containers below 500 mm 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

Product will irritate eyes and skin. Avoid contact with eyes and skin. When preparing product for use wear elbow-length PVC gloves and face shield or goggles. When using controlled droplet applicator wear protective waterproof clothing and impervious footwear. After use and before eating, drinking or smoking, wash hands, arms and face thoroughly with soap and water. After each day’s use wash contaminated clothing, gloves and face shield or goggles.
