Restraints: RESTRAINTS:
DO NOT apply to plants which may be stressed (not actively growing) due to prolonged
periods of extreme temperature (less than 5ºC or greater than 30ºC), moisture stress
(water-logged or drought affected), poor nutrition or previous herbicide treatment as
reduced levels of control may result.
DO NOT apply to plants which have suffered frosting for extended periods. Allow at least 2
days frost free prior to treatment.
DO NOT apply post-emergence treatments if rain is likely within 4 hours or if heavy rain is
expected within 48 hours of application.Page 2
DO NOT irrigate (any method) treated crop or pasture for 48 hours after application.
DO NOT apply to crops affected by disease or by previous herbicide treatment (eg. triazines
or sulfonylureas).
DO NOT apply Broadstrike® under conditions likely to cause drift onto waterways,
susceptible crops or land to be planted with susceptible crops.
SPRAY DRIFT RESTRAINTS:
Specific definitions for terms used in this section of the label can be found at apvma.gov.au/
spraydrift
DO NOT allow bystanders to come into contact with the spray cloud.
DO NOT apply in a manner that may cause an unacceptable impact to native vegetation,
agricultural crops, landscaped gardens and aquaculture production, or cause contamination
of plant or livestock commodities, outside the application site from spray drift. Wherever
possible, correctly use application equipment designed to reduce spray drift and apply when
the wind direction is away from these sensitive areas.
DO NOT apply unless the wind speed is between 3 and 20 kilometres per hour at the
application site during the time of application.
DO NOT apply if there are hazardous surface temperature inversion conditions present at
the application site during the time of application. Surface temperature inversion conditions
exist most evenings one to two hours before sunset and persist until one to two hours after
sunrise.

Other Limitations:
Withholding Periods: HARVESTING WITHHOLDING PERIODS:
Chickpeas, field peas, lentils, maize, peanuts and soybeans: NOT REQUIRED WHEN
USED AS DIRECTED.
Winter cereals: DO NOT HARVEST FOR 4 WEEKS AFTER APPLICATION.
GRAZING/STOCK FOOD WITHHOLDING PERIODS:
Chickpeas, field peas, lentils, peanuts, soybeans, Popany vetch: DO NOT GRAZE OR CUT
FOR STOCK FOOD FOR 4 WEEKS AFTER APPLICATION.
Barley, cereal rye, oats, triticale, wheat, grass pastures: DO NOT GRAZE FOR 3 DAYS
AFTER APPLICATION.
DO NOT CUT FOR STOCK FOOD OR HARVEST FOR SEED FOR 4 WEEKS AFTER
APPLICATION.
Maize: DO NOT GRAZE OR CUT FOR STOCK FOOD FOR 14 DAYS AFTER
APPLICATION.
Clover, fenugreek, lathyrus, lucerne, medic, serradella: DO NOT GRAZE OR CUT FOR
STOCK FOOD OR HARVEST FOR SEED FOR 3 DAYS AFTER APPLICATION.
EXPORT SLAUGHTER INTERVAL (ESI) – 7 days
After observing the withholding period for grazing or cutting for stock food, livestock that
have been grazed on or fed treated crops, should be placed on clean feed for 7 days prior
to slaughter.
EXPORT ANIMAL FEED INTERVAL (EAFI) – 28 days (Clover, Fenugreek, lathyrus, medic,
Popany vetch, lucerne, pasture and serradella only)
A minimum period of 28 days must elapse between the application of Broadstrike® and
grazing or cutting the treated pasture as stockfeed for livestock intended for export.Page 3
For tank-mixtures - use the longest withholding period specified on each of the respective
labels. Particularly note longer withholding periods on bromoxynil labels.
Trade Advice: LIVESTOCK DESTINED FOR EXPORT MARKETS
The grazing withholding period only applies to stock slaughtered for the domestic market.
Some export markets apply different standards. To meet these standards, ensure that in
addition to complying with the grazing withholding period, that the Export Slaughter Interval
(ESI) is observed before stock are sold or slaughtered.

Resistance Warning: RESISTANT WEEDS WARNING
GROUP 2 HERBICIDE
Broadstrike® Herbicide is a broadleaf herbicide with no annual ryegrass activity and is
a member of the triazolopyrimidine sulfonanilide (sulfonamide) group of herbicides. The
product has the acetolactate synthase (ALS) inhibitor mode of action. For weed resistance
management the product is a Group 2 herbicide. Some naturally occurring weed biotypes
resistant to the product and other Group 2 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 this product or other Group 2 herbicides. Since the occurrence of resistant
weeds is difficult to detect prior to use, Corteva Agriscience Australia PTY LTD accepts
no liability for any losses that may result from the failure of the product to control resistant
weeds. Strategies to minimise the risk of herbicide resistance are available. Contact
your farm chemical supplier, consultant, local Department of Agriculture, or local Corteva
Agriscience representative.
Precautions:
Protections:
PROTECTION OF CROPS, NATIVE AND OTHER NON-TARGET PLANTS
Dangerous to aquatic plants.
DO NOT allow spray to drift on to susceptible crops. Crops susceptible to Broadstrike®
Herbicide include but are not limited to canola, cotton, faba beans, lupins, sorghum and
sunflowers.
Refer to MINIMUM RECROPPING PERIODS for crop rotation information.
PROTECTION OF LIVESTOCK
DO NOT graze or cut treated crops for stock food except as specified under withholding
periods.
Poisonous plants may become more palatable after spraying, therefore livestock should be
kept out of the area until the plants have died down.
PROTECTION OF WILDLIFE, FISH, CRUSTACEANS AND ENVIRONMENT
DO NOT contaminate streams, rivers or watercourses with the chemical or used containers.Page 4
Storage and STORAGE AND DISPOSAL
Disposal: Keep Out of Reach of Children.
Store in the closed, original container in a securely locked, dry, cool, well-ventilated place,
out of direct sunlight.
DO NOT store near food, feedstuffs, fertilisers or seed.
DO NOT dispose of any undiluted chemical on-site.
The method of disposal of the container depends on the container type. Read the
STORAGE AND DISPOSAL instructions on the label that is attached to the container.
For 100 g and 500 g foil bags
When the foil bag is empty, shake any residual material into the spray tank. DO NOT
dispose of undiluted chemicals on site. Puncture and deliver empty packaging to an
approved waste management facility. If an approved waste management facility is not
available, bury the empty packaging 500 mm below the surface in a disposal pit specifically
set up for this purpose, clear of waterways, desirable vegetation and tree roots, in
compliance with relevant local, state or territory government regulations. DO NOT burn
packaging or product.
For 500 g - 1 kg HDPE containers
Do not re-use containers.
Triple-rinse container before disposal. Add rinsings to the 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 deliver empty
packaging to an approved waste management facility. If an approved waste management
facility is not available, bury the empty packaging 500 mm below the surface in a disposal
pit specifically marked and set up for this purpose, clear of waterways, desirable vegetation
and tree roots, in compliance with relevant local, state or territory government regulations.
DO NOT burn empty containers or product.
This container can be recycled if it is clean, dry, free of visible residues and has the
drumMUSTER logo visible. Triple-rinse container for disposal. Dispose of rinsate by adding
it to the spray tank. Do not dispose of undiluted chemical on site. Wash outside of the
container and the cap. Store cleaned container in a sheltered place with cap removed. It
will then be acceptable for recycling at any drumMUSTER collection or similar container
management program site. The cap should not be replaced but may be taken separately.
SMALL SPILL MANAGEMENT
Sweep up material and contain in a refuse vessel for disposal in the same manner as for
containers (see STORAGE AND DISPOSAL section).

GENERAL INSTRUCTIONS
Broadstrike® granules readily disperse in water and will do so once added to fast moving water.
Maintain agitation at all times, including during mixing as well as spraying. Only mix sufficient
spray solution for immediate use and avoid storing.
MINIMUM RECROPPING PERIODS:
Broadstrike® is broken down in the soil by microbial activity. Warm, moist soil conditions favour
highest microbial activity and quickest residue breakdown. For the re-cropping periods Nth NSW
and Qld refers to summer dominant rainfall areas, where crops are grown on deep black earth
soils (vertisols), with no impermeable sub-horizon in the top 30 cm. Sth NSW, Vic, Tas, SA and
WA refers to winter dominant rainfall areas on soils with no impermeable sub-horizon in the top
30 cm. Also see the comments on rainfall and soil type below.

Rainfall - is required to maintain soil wetness for at least one week over the warm
months to enable microbial degradation of herbicide residues to allow safe planting
of sensitive crops. For Sth NSW, Victoria, Tasmania, SA and WA a minimum of 25 mm and
preferably 50 mm or more rain must have fallen over the warm months of the year. For Nth
NSW and Qld a minimum of 50 mm and preferably 100 mm rain or more must have fallen over
the warm months of the year.
Soil type - on shallow, duplex, low organic matter soils with an impermeable sub-horizon
within the root zone (30 cm deep or less) and alkaline surface soil, sensitive crops should
NOT be planted until 2 years after application of Broadstrike® at either 25 or 50 g/ha. (For
crops grown in Nth NSW and Qld on soils other than vertisols, call Corteva Agriscience or your
local reseller for more advice).
Where BROADSTRIKE® residue carryover is suspected and susceptible crops are to be
planted, test the treated area as follows:
Where rain allows, plant a small area of the susceptible crop 4 to 6 weeks before desired
planting date and take note of any symptoms of injury. If any herbicide symptoms are observed,
only plant a winter cereal.
Pot bioassay - Where not practical to do field bioassay, plant a small number of seeds of the
susceptible crop into pots containing soil from the treated field. Do this test 4 to 6 weeks before
desired planting date. If any herbicide symptoms are observed, only plant a cereal crop.
Canola and cotton are highly sensitive to BROADSTRIKE® and therefore are a good test
species for a bioassay.Page 18
MIXING
Spray rigs with pre-mix hoppers
For spray rigs that have a dropdown chemical induction hopper, three-quarter fill this
hopper with water and have the rinsing sprinkler operating. Add the Broadstrike®
granules and when they are dissolved and the granules are dispersed, transfer this batch
into the quarter filled main tank. Continue to rinse the hopper until the entire product has
washed through.
Spray rigs with limited bypass agitation
When Broadstrike® is added to the spray tank for spray rigs that have limited
bypass agitation, then as for most granulated formulations, pre-disperse the Broadstrike® in
a bucket before adding them to the main tank. Add Broadstrike® while stirring until the
granules have dispersed.
Tank mixes – this order should be followed:
1. Quarter fill the spray tank and agitate
2. Add Broadstrike® using the mixing procedure above
3. Add Verdict® 520 if it is to be used
4. Half fill the spray tank
5. Add wettable powders, dry flowables, suspension concentrates, soluble liquids
and/or emulsifiable concentrates
6. Add Uptake® Spraying Oil when half full
7. Add other adjuvants according to their label
8. Add water to fill the spray tank
Read and follow all label directions including restraints, spray drift restraints, mandatory no-
spray zones, CRITICAL COMMENTS and SAFETY DIRECTIONS for the tank mix products.
COMPATIBILITY
Broadstrike® is compatible with the following adjuvants:
- Uptake® Spraying Oil at 500 mL/100L.
- 100% non-ionic surfactant such as BS-1000® or Chemwet 1000 at 200 mL/100L.
Other brands have not been tested. Consult your Corteva representative before using
alternate products.
APPLICATION
• Ground Application: Apply Broadstrike® in 50 to 150 litres of water per hectare through a
calibrated sprayer that delivers fine-medium quality spray as defined by the ASAE
Standard S572.
• Best results are achieved where applications are made on warm (greater than 5ºC),
sunny days applying more than 50 L/ha of total spray volume (preferably more than 75
L/ha) and where spray coverage is maximised.Page 19
CLEANING SPRAY EQUIPMENT
After using Broadstrike®, empty the tank completely and drain the whole system. Thoroughly
wash inside the tank using a pressure hose. Drain the tank and clean any filters in the tank,
pump, lines and nozzles.
• To rinse. After cleaning the tank as above, quarter fill the tank with clean water and
circulate through the pump, lines, hoses and nozzles. Drain and repeat the rinsing
procedure twice.
• To decontaminate. Before spraying sensitive crops (which include but are not limited to
canola, cotton, faba beans, lupins, sorghum and sunflowers), wash the tank and rinse the
system as above. Quarter fill the tank and add an alkali detergent at 500 mL/100 L of
water or the powder equivalent at 500 g/100 L and circulate throughout the system for at
least fifteen minutes. Drain the whole system. Remove filters and nozzles and clean them
separately. Finally flush the system with clean water and allow to drain. Chlorine based
cleaners are not recommended. Nufarm Tank and Equipment Cleaner is not
recommended.
Rinse water should be discharged onto a designated disposal area or, if this is
unavailable, onto unused land away from desirable plants and watercourses.
