General Instructions:

GENERAL INSTRUCTIONS

RELYON PROSULFOCARB is a short residual, soil applied, pre-emergent herbicide that

is absorbed by the roots and shoots (coleoptile) of germinating seedlings with inhibition of

growth in the meristematic region. Foliar uptake is possible but of lower effect. Upstream

translocation in the plant occurs but movement in the phloem is very unlikely. Best activity

can be expected from applications before or shortly after the germination of target weeds.

The product should be applied to a moist smooth seedbed free of soil clods and emerged

weeds. Product efficacy may be reduced by improper incorporation, high levels of crop or

trash residues, stones or foreign matter and in areas of extremely high weed seed density

such as header rows. For optimal efficacy and crop safety avoid shallow seeding and

ensure accurate seed placement that avoids placement of seed in the herbicide band.

Avoid water repellent soils, soils subject to waterlogging or where furrow walls are likely to

collapse.

Duration and effectiveness of weed control will depend on use rate, soil type and rainfall or

irrigation after application. Adequate rainfall should occur within 10 days of application, as

this herbicide requires sufficient available soil moisture to ensure soil movement and uptake

by emerging weed seeds.

CROP TOLERANCE

The selectivity of RELYON PROSULFOCARB in cereals is a combination of positional

and physiological selectivity. Positional selectivity must be maintained by sowing at

adequate depth below the herbicide band. The physiological selectivity of RELYON

PROSULFOCARB is given by the ability of cereals to metabolise the herbicide to inactive

compounds more rapidly than susceptible weed species. Environmental factors such as

rainfall events following application and soil type will influence product movement into the

seed zone. Crop damage may result where tank mixed with other herbicides, heavy rainfall

follows sowing, in the event of crop stresses including frost or in sandy soils with high

leaching potential. Risk of crop damage may be exacerbated where varieties with short

coleoptile length are planted in conjunction with the use of some fungicide seed treatments.

TILLAGE SYSTEM

IBS with knife or blade points: Working speed should ensure adequate incorporation

of product but avoid soil throw into the adjacent seeding row. Use of presswheels will

minimise potential for herbicide to be dragged back into seeding rows. Weed control may

be reduced in seeding rows as a result of concentration of herbicide in crop inter-rows. A

knife or blade point is defined as being <12 mm in width, having no wings, inverted T or

blade and is generally on a minimum 200 mm row spacing.

Full disturbance or conventional cultivation, including trailing harrows/prickle chain: Care

should be taken to ensure seed placement below the herbicide band as crop damage may

result where seed is sown too shallow. Consult trifluralin label for tank mix rate selection.

PRODUCT MUST BE INCORPORATED INTO THE SOIL WITHIN 7 DAYS OF

APPLICATION

MIXING

RELYON PROSULFOCARB and S-METOLACHLOR are emulsifiable concentrates

that mixes readily with water. Fill the spray tank to one quarter full. Add RELYON

PROSULFOCARB and S-METOLACHLOR and continue adding water to make up to the

final spray volume. Agitate while mixing and spraying.

When tank mixing wettable powder or water dispersible granule formulations, these

should be added to the tank first followed by suspension concentrates (flowables), water

soluble salts then RELYON PROSULFOCARB, S-METOLACHLOR and other emulsifiable

concentrate formulations. Maintain thorough agitation during mixing and application. Agitate

tank mixes vigorously if allowed to stand. Note: Tank mix spray solutions should NOT be

left standing in the vat overnight.

COMPATIBILITY

RELYON PROSULFOCARB is compatible with any one of the following herbicides: 2,4-

D (amine and ester), carfentrazone, diquat+paraquat, glyphosate, Logran^ B-Power^

Herbicide, metsulfuron methyl, oxyfluorfen, s-metolachlor, triasulfuron, and trifluralin. DO

NOT tank mix with 2,4-D (amine or ester).

Always refer to plant back restrictions on the label of the tank mix partner.

RELYON PROSULFOCARB is compatible with any one of the following insecticides: alpha

cypermethrin, bifenthrin, chlorpyriphos, dimethoate and lambda-cyhalothrin.

RELYON PROSULFOCARB is compatible with liquid Urea Ammonium Nitrate (UAN)

fertilisers provided the spray solution is under constant high agitation.

As formulations of other manufacturers' products are beyond the control of Nutrien Ag

Solutions and water quality varies with location, all mixtures should be tested prior to mixing

commercial quantities.

APPLICATION

Apply by ground rig only in a minimum of 50 L water/ha. Water rate selection should be

based on soil type and stubble load. Stubble loads above 40 to 50% ground coverage can

reduce weed control below acceptable levels. Water volumes greater than 70 L/ha are

recommended in order to reduce the impact of stubble in direct drill or minimum tillage

systems. Use a nozzle delivering spray quality in the medium to very coarse spray range.

DO NOT apply by air.

Resistance Warning:

RESISTANT WEEDS WARNING

GROUP J HERBICIDE

RELYON PROSULFOCARB is a member of the thiocarbamates and amides group of

herbicides. This product has the inhibitors of fat synthesis mode of action. For weed

resistance management, this product is a Group J herbicide. Some naturally occurring

weed biotypes resistant to this product and other Group J 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 J herbicide. Since the

occurrence of resistant weeds is difficult to detect prior to use, Nutrien Ag Solutions Limited

accepts no liability for any losses that may result from the failure of this product to control

resistant weeds. Advice as to strategies and alternative treatments that can be used should

be obtained from your local supplier, consultant, local Department of Agriculture, Primary

Industries Department or a Nutrien Ag Solutions representative.

RESISTANCE MANAGEMENT

Large numbers of healthy surviving weeds can be an indication that resistance is

developing. Efforts should be made to prevent seed set of the surviving weeds. DO NOT

make more than one application of a Group J herbicide to a crop in the same season.

If the user suspects that the target weed population is resistant to herbicides with this mode

of action, RELYON PROSULFOCARB or other Group J herbicides should not be used.

Strategies to minimise the risk of herbicide resistance are available. The above

recommendations should be incorporated into an Integrated Weed Management (IWM)

Program that uses a diverse range of options to manage grass weeds and avoids over

reliance on any one method of control. Consult your farm chemical supplier, consultant,

local Department of Agriculture or Primary Industries, or local Nutrien Ag Solutions

representative for details.

TANK MIXES

Application of less than 2.5 L/ha RELYON PROSULFOCARB (plus 313 mL S- Metolachlor

960 g/L) when tank mixing with other herbicides for Annual Ryegrass control WILL NOT

be effective in the control of Group D resistant populations nor to in delay of the onset of

herbicide resistance development. Tank mixing of herbicides is only effective in managing

resistance where a lethal dose rate of each herbicide is applied. Whilst a tank mixture of 2

herbicides of differing modes of action at sub-lethal dose rates may still provide a high level

of weed control, the risk of developing resistance to multiple modes of action is increased.

Tank mixtures of RELYON PROSULFOCARB plus S-METOLACHLOR with trifluralin are

only recommended where targeting additional weed species, on sandy soils where soil

moisture is limiting or where product movement into the seeding zone poses a crop safety

risk.

Precautions:

RE-ENTRY PERIOD: Do not allow entry into treated areas until the spray has dried, unless

wearing cotton overalls buttoned to the neck and wrist (or equivalent clothing) and chemical

resistant gloves. Clothing must be laundered after each day’s use.

Protections:

PROTECTION OF CROPS, NATIVE AND OTHER NON-TARGET PLANTS

DO NOT sow susceptible crops within 9 months of herbicide application.

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.

DO NOT allow spray to drift onto adjacent fallow land.

DO NOT apply on or near shrubs, trees, lawns or crops other than wheat or barley.

DO NOT drain or flush equipment on or near desirable trees or other plants, where their

roots may extend, or in situations where by movement of soil or by seepage absorption of

the herbicide may occur.

PROTECTION OF WILDLIFE, FISH, CRUSTACEANS AND ENVIRONMENT

HIGHLY TOXIC TO AQUATIC ORGANISMS. DO NOT contaminate streams, rivers or

watercourses with the chemical or used containers.

DO NOT apply under meteorological conditions or from spraying equipment which could be

expected to cause spray to drift onto adjacent areas, particularly wetlands, waterbodies or

watercourses.

Storage and

Disposal:

Store in the closed, original container in a cool, well ventilated area. DO NOT store for

prolonged periods in direct sunlight.

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.
