Fireball 400 Herbicide (Fluroxypyr)

Tips For Use

Restraints:

• Do not apply to plants which may be stressed (not actively growing) due to prolonged periods of extreme cold, moisture stress (water-logged or drought affected) poor nutrition, presence of disease, or previous herbicide treatment as reduced levels of control may result.
• Thorough coverage of both foliage and stems, to the point of runoff, is essential for high volume applications (see General Instructions; application methods Woody Weed Situations section).
• Do not spray if rain is likely to occur within one hour.

General Instructions:

Mixing:

Fireball 400 Herbicide may be mixed with water or diesel.

Mix only sufficient chemical for each day’s use and avoid storing.

• Mixing in Water: Half fill the spray tank with water and add the required quantity of Fireball 400 Herbicide and complete filling. Agitate continuously to ensure thorough mixing before and during application.
• Mixing in Diesel: Half fill the tank with diesel and add the required quantity of Fireball 400 Herbicide. Add the remainder of the diesel and agitate or shake to mix contents.
• Tank mixtures: Wettable powder or dry flowable formulations (e.g. water dispersible granules) should be added to the spray tank first, followed by suspension concentrates  flowables), water soluble salts and then emulsifiable concentrate formulations (Fireball 400 Herbicide). Add spraying oils and surfactants (wetters) last.

Oils and Surfactants:

• Oils: Where specified use only Uptake Spraying Oil at the rate of 500 mL/100 L of spray mix. When using less than 100 L/ha spray volume, ensure a minimum of 250 mL/ha of Uptake is used, unless 1 L/100 L or 1 L/ha is specified.
• Surfactants (Wetters): Use a 100% concentrate non-ionic surfactant such as Wetter 1000 at 100 mL/100 L of spray mix where required.

Application Methods and Water Rates:

Broadcast Application in Cropping, Pasture and Fallow Situations:

Ground application (Boom): Apply Fireball 400 Herbicide with an accurately calibrated boom sprayer, in at least 50 L/ha water (100-400 L/ha for sugar cane).

Flat nozzles are recommended using pressures in the range 200 to 300 kPa.

Set the boom at a height to ensure a double overlap of the nozzle patterns.

Ground directed application (Dropper nozzles): To minimise crop effects, dropper nozzles should be used in sorghum when the crop is beyond the 8 leaf growth stage and in maize and sweet corn when the crop is beyond the 6 leaf growth stage. Adjust the nozzles to direct the spray into the base of the crop and away from the leaves and the growing point. See manufacturers directions for setting up and calibration of dropper nozzles

Aerial Application: Apply in a minimum volume of at least 35 L/ha water (60 L/ha in sugarcane). Use equipment calibrated to produce droplets with an average diameter (Volume Mean Diameter; VMD) of 250 – 350 microns. 

Do not apply when the temperature is above 30 degrees celsius, when there is no wind or when the wind is blowing toward susceptible crops.

Do not use human flaggers unless they are protected by engineering controls such as enclosed cabs.

Woody Weed Situations:

Weeds must be actively growing to attain optimal effect. Delay the treatment of regrowth following bulldozing, slashing, burning, ploughing or a previous chemical treatment until it has at least 1 metre of new, vigorous, growth.

High Volume Application

Hand Gun: Apply the recommended mix to obtain full coverage of leaves and stems using a number 6 – 8 tip at 700 to 1500 kPa. To obtain good coverage, a spray volume of 1500 to 4000 L/ha (15 to 40 L/100m2) is required per infested hectare. Ensure thorough coverage to the point of runoff.

Knapsack: Knapsack sprayers may be used on smaller infestations where penetration and coverage of the canopy is easier to achieve. Use the same use rate and spray techniques as for handgun application.

Low Volume, High Concentrate Application

Drench Gun or Gas-Powered Gun: Apply the recommended mixture uniformly across the foliage by applying 50mL shots to cover 4 to 5 m2 of surface area of plant. This is approximately equivalent to 20 droplets per cm2 of the leaf surface. Use a marking agent as recommended by the equivalent manufacturer to check spray coverage.

Basal Bark and Cut Stump Application

Basal Bark: Do not apply to wet stems as this can repel the diesel mixture. Spray or paint the recommended mixture around the base of each stem from ground level to a height of at least 30 cm from the ground, wetting the bark to the point of runoff. Apply with a paint brush or a pressure sprayer with an approximate lance and solid cone nozzle. If using spray equipment use low pressures (< 200 kPa) sufficient to form a cone of spray. Old rough bark will require more spray than smooth or young thin bark.

Cut Stump: Apply the recommended mixture liberally to the freshly cut stump immediately after cutting. Apply by spraying or painting the cut surface and sides of the stump. Best results are obtained when the stems are cut less than 15 cm above the ground.

Safety Directions:

• Avoid contact with eyes and skin.
• When opening the container, preparing the spray and using the prepared spray wear cotton overalls buttoned to the neck and wrist and a washable hat, elbow length PVC gloves, a face shield or goggles.
• Wash hands after use.
• After each day’s use, wash gloves, face shield or goggles and contaminated clothing.

First Aid:

• If poisoning occurs, contact a doctor or Poisons Information Centre (Australi Ph: 13 11 26).
• If swallowed, do not induce vomiting.  Give a glass of water.
• Additional information is listed on the Safety Data Sheet (SDS).
