Trade Advice:

General Instructions:

Sabakem Prosulfocarb 800 EC Herbicide 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 water logging 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 or irrigation 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 Sabakem Prosulfocarb 800 EC Herbicide 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 Sabakem

Prosulfocarb 800 EC Herbicide 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 injury may occur when used in sandy soils with high

leaching potential or in all soil types when heavy rainfall is received between sowing and

emergence. Crop injury may also result from tank mixes with other herbicides. Shallow

seeding is not recommended due to the greater potential for movement of herbicide within

close proximity of the emerging crop. Conditions resulting in poor root development or the

occurrence of crop stresses including waterlogging, drought, frost, nutrient deficiency or

disease can result in unacceptable crop damage and yield loss as a result of root uptake of

herbicide. 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. Consult

your local agronomist, advisory service or National Variety Trial (NVT) herbicide tolerance

screening results for the latest information of specific varietal tolerance.

Tillage System

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

product but avoid soil throw into the adjacent seeding row. Use of press wheels 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 trifuralin label for tank mix rate selection.

PRODUCT MUST BE INCORPORATED INTO THE SOIL WITHIN 7 DAYS OF

APPLICATION

Mixing

Sabakem Prosulfocarb 800 EC Herbicide is an emulsifiable conentrate that mixes readily

with water. Fill the spray tank to one quarter full. Add Sabakem Prosulfocarb 800 EC

Herbicide 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 should be added to the tank first followed by suspension concentrates

(flowables), water soluble salts then Sabakem Prosulfocarb 800 EC Herbicide or 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.

Sprayer Clean Up

After using Sabakem Prosulfocarb 800 EC Herbicide, 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, line 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.

Compatibility

As formulations of other manufacturers’ products are beyond the control of Sabakem Pty

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

commercial quantities.

Application

DO NOT apply by air.

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.

Tank Mixes

Application of Sabakem Prosulfocarb 800 EC Herbicide at less than 2.5 L/ha when tank

mixing for Annual Ryegrass control WILL NOT be effective in the control of Group D

resistant populations nor to delay 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 Sabakem

Prosulfocarb 800 EC Herbicide 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.

Resistance Warning:

Sabakem Prosulfocarb 800 EC Herbicide is a member of the thiocarbamates 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 herbicides. Since the

occurrence of resistant weeds is difficult to detect prior to use, Sabakem Pty Ltd 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 Sabakem Pty Ltd representative.

Resistant 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 1 application of a Group J herbicide with the inhibition of fat acid synthesis

mode of action 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, Sabakem Prosulfocarb 800

EC Herbicide 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 far chemical supplier, consultant, local Department of Agriculture or primary

Industries, or local Sabakem Pty Ltd representative for details.

Precautions:

RE-ENTRY PERIOD

DO NOT enter 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:
