DIRECTIONS FOR USE
IMPORTANT: This information is approved as part of the Product Label. All instructions within this section must be read carefully in order to obtain safe and successful use of this product.

GENERAL INFORMATION
Rosate 36 is a soluble concentrate herbicide, containing the active ingredient glyphosate, for the control of most species of emerged annual and perennial grass and broad-leaved weeds. It is adsorbed by the weed foliage and translocated to the growing points in the roots and to the underground rhizomes/stolons of perennial weeds. Best results are obtained from applications made under good growing conditions (adequate soil moisture and warm/humid conditions), when the weeds are actively growing and at the recommended growth stages for treatment. After application, glyphosate is strongly adsorbed onto the soil particles and becomes practically immobilized within the soil. As a result, it has no further herbicidal activity and it is subsequently broken down by microbial activity. New crops can be sown or planted at very short intervals after application.

WARNINGS AND RESTRICTIONS
TAKE EXTREME CARE TO AVOID SPRAY DRIFT to avoid severe damage or complete destruction of plants outside the target area. 
DO NOT APPLY under windy conditions. 
DO NOT MIX, STORE, USE OR APPLY IN GALVANISED OR UNLINED STEEL 
CONTAINERS OR SPRAY TANKS. 
DO NOT allow the spray mixture to stand in the tank for a long period and make sure spray tanks are well vented. FOLIAGE OF ANY POISONOUS WEEDS (SUCH AS RAGWORT) MUST BE REMOVED OR BURIED PRIOR TO GRAZING OR CUTTING FOR FEED when applications are made to foliage which will be subsequently fed to stock in any way.
At least 6 hours are required for the spray to become rainfast and taken up by the foliage after application. For maximum efficacy, it is preferable that at least 24 hours elapse before any rainfall occurs after application. 
Do not apply where the target weeds are senescing naturally or if they are under stress, particularly from drought, high temperatures or frost, as they may be poorly controlled under these conditions. Weed control will take longer when weeds are growing slowly. 
Do not cultivate BEFORE application. 
After application, Rosate 36 takes several days to fully translocate through the plant. For this reason, do not make applications of fertiliser, lime, manure or other pesticides for at least 5 days before or after application. 
Do not tank-mix with any other product except with a suitable authorised adjuvant where specifically recommended on this label. After application, large concentrations of decaying foliage, roots, or rhizomes/stolons should be dispersed or buried by thorough cultivation before crop drilling. Trace amounts of Rosate 36 remaining in the sprayer after use can cause damage to other crops subsequently treated with the same equipment. Immediately after use thoroughly clean the sprayer and all equipment as detailed in the section “SPRAYER DECONTAMINATION”.

TRANSFORMATION PROCESSES
Effects on brewing and baking have not been established. Consult grain merchant or processor before use.

WEEDS CONTROLLED
Rosate 36 controls most species of emerged annual and perennial grass and broad-leaved weeds. After application the active ingredient is translocated from the treated foliage to the roots and other underground parts of perennial plants. Weeds are most susceptible to Rosate 36 when they are actively growing under warm, humid conditions with adequate soil moisture. Poor control will occur if application is made to weeds that are subject to natural senescence or if their growth is held back by dry conditions, waterlogging, high temperatures or frost. Weed control can also be reduced if these conditions occur soon after application. Any other situation that restricts uptake into the plant (e.g., a covering of dust on the foliage from wind-blown soil) will reduce levels of weed control. It is important that weeds are actively growing and at the correct growth stages at the time of application, otherwise re-growth can occur and will require subsequent re-treatment. Symptoms of weed control are usually seen within 7 – 10 days after application but it may take longer under poor growing conditions. Treated foliage usually shows a gradual wilting and loss of vigour followed by a slight reddening then yellowing followed by plant death. Symptoms are usually seen on grass weeds before becoming apparent on broad-leaved weeds. Complete death and deterioration of the weed foliage and root system may take up to 4 weeks or longer under poor growing conditions. For application rates of Rosate 36 of 2.0 litres per ha or less, in certain situations it is recommended to add a suitable authorised adjuvant. Do not use an adjuvant when applying through a rotary atomiser sprayer.

Annual Weeds
For best results annual weeds must be growing actively at the time of application. Annual grass weeds should have at least 5 cm of emerged leaf length and broad-leaved weeds should have at least 2 fully expanded true leaves. When used for the control of green cover on land not being used for production, annual grasses such as Black-grass and Brome grasses should be treated either at full ear emergence or before stem elongation. Treatments made during the stem elongation phase of annual grasses may result in poor weed control and require a further application.

Perennial Weeds
For best results perennial broad-leaved weeds must be treated when they are actively growing (they are most susceptible around the time of flowering). Perennial grass weeds must have developed an actively growing fully emerged foliage when the application is made. For Common couch the tillering stage (when the growth of new rhizomes starts) is the most susceptible growth stage. This is usually when there are 4 – 5 leaves, each about 10 – 15 cm in length. The action of Rosate 36 on the control of Nettles is slow and it does not give an acceptable level of control of Horsetails (Equisetum arvense) from a single application.

FOLLOWING CROPS
After application, glyphosate is strongly adsorbed by the soil particles and subsequently broken down by microbial activity. Once absorbed onto the soil, Rosate 36 has no further herbicidal activity and crops can be sown or drilled at specified intervals after application. However, a slight check to crop growth can occur if seeds of the newly planted crop germinate within the residual mat of dying and decaying weed foliage, roots, or rhizomes/stolons. Direct drilled crops are particularly susceptible. Cultivate the ground thoroughly to disperse or bury the decaying organic matter remaining after application. Loose or fluffy soils/seedbeds should be consolidated and a normal programme of fertiliser and crop protection treatments should be applied as appropriate to the new crop, particularly where this follows destruction of grassland. 
Trees and shrubs may be planted 7 days after application. 
Grass may be sown 14 days after application. 
All other crops may be sown or planted 2 days after application

RESISTANCE MANAGEMENT
There is low risk for the development of weed resistance to Rosate 36. Strains of some annual weeds (e.g., Black-grass, Wild oats and Italian Ryegrass) have developed resistance to herbicides which may lead to poor control. A strategy for preventing and managing such resistance should be adopted. This should include integrating herbicides with a programme of cultural control measures. Guidelines have been produced by the Weed Resistance Action Group and copies are available from the HGCA, CPA, your distributor or crop adviser. Implement a weed resistance strategy based on Good Agricultural Practice and including the following:
Follow the label recommendations. 
Adopt complementary weed control practices. 
Minimise the risk of spreading weed infestations.
Implement good spraying practice to maintain effective weed control. Use the correct spray nozzles to maximise coverage. 
Apply only under appropriate weather conditions.
Monitor herbicide performance and report any unexpected results to Albaugh Europe Sàrl

APPLICATION
Before use, make sure the spraying equipment is cleaned from any previous use and that it is calibrated to apply the recommended spray volume and pressure. This is particularly important when using low-volume applications. After use, make sure the sprayer and all equipment is thoroughly cleaned as detailed in the section “SPRAYER DECONTAMINATION”. Do not store, mix or use in unlined or galvanized steel tanks or equipment. Spray immediately after mixing, do not allow the mixture to stand for long periods in the spray tank and ensure that tanks are well ventilated.

Tractor-mounted or Trailed Sprayers
Before use, make sure the sprayer is cleaned from any previous use and calibrated to apply the recommended spray volume and pressure. Make sure all the sprayer nozzles are performing equally and that the spray boom is set at the correct height above the target weeds. This is particularly important when making pre-harvest applications to a crop. Unless a different water volume is specified under “Crop Recommendations”, apply in 80 – 250 litres of water per hectare as a MEDIUM or COARSE spray (BCPC) and with a spray pressure of 1.5 – 2.5 bars using suitable 80° or 110° nozzles. For best results and to reduce the risk of spray drift, use a spray pressure within this range. The preferred application volume is normally between 200 – 250 litres per ha but this can be reduced with the use of appropriate low volume nozzles, adjusting spray pressure and tractor ground speed (tractor speed will typically need to be set to 4 – 9 kph). Do not allow the spray boom to bounce or yaw, this is particularly important for pre-harvest applications. Ensure that the water volume selected gives a good even spray cover of the target weeds. Half fill the sprayer tank with clean water and begin gentle agitation. To avoid the mixing operation resulting in excessive foaming, do not use agitation from the top of the tank. Add the required quantity of product into the sprayer tank and allow to disperse fully. Rinse the containers thoroughly by using an integrated pressure rinsing device or manually rinsing three times. Add the washings to the sprayer and continue agitation whilst topping up the tank with water to the required level. Continue agitation until the mix is sprayed out. The use of a de-foaming product may be necessary. Spray immediately after mixing, do not allow the mixture to stand. If a tank-mix with an authorised adjuvant is being used, add to the sprayer tank separately, and follow any specific instructions on the order of mixing.

Knapsack Sprayers
Knapsack sprayers may be used for spot or directed applications, for example to land not intended to bear vegetation, orchards, non-crop areas and in forest and farm forestry. Apply in 100 – 300 litres of water per hectare as a MEDIUM or COARSE spray (BCPC). For water volumes in the range of 100 – 150 litres of water per ha, it will be necessary to fit low volume spray nozzle(s). Example spray dilution calculation: To apply 5.0 litres per ha of Rosate 36 in a water volume of 200 litres per ha in a sprayer tank of capacity 5 litres, add 125 ml of Rosate 36 to 4.88 litres of water in the sprayer tank. This volume of diluted spray will cover an area of 250 m2. Do not make up a spray solution of a greater quantity than required for the area to be treated. Ensure an even spray coverage with an even walking speed during application. Half fill the sprayer tank with clean water. Add the required quantity of product into the sprayer tank and allow to disperse fully. Rinse any empty containers thoroughly by using an integrated pressure rinsing device or manually rinsing three times. Add the washings to the sprayer and top up the tank with water to the required level and mix thoroughly by agitating the tank. Spray immediately after mixing, do not allow the mixture to stand. If a tank-mix with an authorised adjuvant is being used, add to the sprayer tank separately, and follow any specific instructions on the order of mixing.

Rotary Atomiser Sprayers 
Apply through a rotary atomizer sprayer using a minimum water volume of 40 litres per ha and a spray droplet spectrum of a minimum Volume Median Diameter (VMD) of 200 microns and up to 300 microns. This corresponds to a MEDIUM or COARSE spray (BCPC). The tractor forward speed will typically be in the range of 4 – 9 kph but it must be calibrated in the field to apply the correct spray volume. Use a spray bout marker to avoid overlapping spray bouts. Do not tank-mix Rosate 36 with any adjuvant when applying through Rotary Atomiser Sprayers.

Hand-held Weedwipers
For use only in orchards and non-crop situations. Use a concentration of 1 part of Rosate 36 to 2 parts of water. Do not exceed this maximum concentration and add a dye (water-based) if necessary 

Tractor-mounted Weedwipers
Tractor-mounted weedwipers may be used in grassland and arable crops for the control of Weed beet, Sugar beet bolters and other tall weeds growing above the crop. 
DO NOT USE WEEDWIPERS IN SOFT FRUIT CROPS. 
WEEDS THAT ARE NOT ACTIVELY GROWING WILL NOT BE CONTROLLED. 
KEEP STOCK OUT of treated areas for 7 days. 
THE FOLIAGE OF ANY POISONOUS WEEDS (SUCH AS RAGWORT) MUST BE REMOVED OR BURIED PRIOR TO GRAZING OR CUTTING FOR FEED. To ensure that application does not result in crop damage, the weeds should always be at least 10 cm taller than the crop vegetation and a distance of 5 cm must be maintained between the top of the crop vegetation and the wiper. The optimum weed height for treatment is 10 cm above the height of the crop vegetation. If the weed vegetation is dense, it will be necessary to make two passes of the wiper from opposite directions of the tractor travel. Weeds growing from below the wiped area will need subsequent applications. 
To minimize weed seed return to the soil, application should be made prior to weed seed maturity. For sugar beet bolters, apply a programme of three applications with an interval of two weeks between applications starting in early July to early August. 
Use a concentration of 1 part of Rosate 36 to 1 part of water. Do not exceed this maximum concentration. Under very hot or dry conditions it may be necessary to reduce the concentration to 1 part of Rosate 36 to 2 parts of water. For best results, ensure that the wiping surface is impregnated with the herbicide solution at all times but does not drip. Clean the wiping ropes as required during the working day to ensure that flow rate to the wiping surface is maintained at full rate at all times. The maximum recommended forward speed is 5 kph or less

CROP RECOMMENDATIONS
Pre-harvest Treatment in Arable Crops
Rosate 36 can be applied as a pre-harvest treatment for the control of weeds in certain recommended arable crops prior to harvest for the control of a range of perennial and annual grass and broad-leaved weeds. DO NOT TREAT CROPS GROWN FOR SEED. Consult the processor before use on any crop intended for processing 

Wheat (including Durum Wheat), Barley and Oats 
Apply when the moisture of the youngest grains in the ear is below 30% and not less than 7 days before harvest. Make an accurate measurement of seed moisture immediately prior to application. DO NOT TREAT CROPS GROWN FOR SEED. To minimise crop damage, apply using a high-clearance tractor fitted with narrow wheels and crop dividers. Do not use straw from a treated crop as a horticultural mulch. Straw from a treated crop may be used for any other purpose. After harvest, straw may be chopped, incorporated or removed according to normal practice and the land can be cultivated normally after harvest and straw disposal. For best results if dull weather conditions occur after application, allow up to 14 days between application and harvest.
Certain broad-leaved weeds (Annual nettle, Rosebay willow-herb, Redshank, Pale persicaria and Knotgrass) are not susceptible at rates of 1.5 l/ha or less. For application rates of Rosate 36 of 2.0 litres per ha or less, in certain situations it is recommended to add a suitable authorised adjuvant. Do not use an adjuvant when applying through a rotary atomiser sprayer. Apply in 80 – 250 litres of water per ha by means of a hydraulic nozzle sprayer – use a higher volume within this range where the crop canopy and/or weed foliage is dense. Alternatively apply in a minimum of 40 litres of water per ha using a rotary atomiser sprayer ensuring that the spray droplet spectrum is in the range of a Volume Median Diameter (VMD) of 200 – 300 microns. Select the correct application rate according to the weed species to be treated, weed population or situation as in the table below.

Oilseed Rape and Mustard 
Apply when the moisture of the grains (crop seeds) is below 30% and at the timing as indicated below. Make an accurate measurement of seed moisture immediately prior to application. 
Oilseed Rape: 14 – 21 days before harvest. Observe the latest time of application of 14 days before harvest. 
Mustard: 8 – 10 days before harvest. Observe the latest time of application of 8 days before harvest.

DO NOT TREAT CROPS GROWN FOR SEED. 
To minimise crop damage, apply using a high-clearance tractor fitted with narrow wheels and crop dividers. After harvest, straw may be chopped, incorporated or removed according to normal practice and the land can be cultivated normally after harvest and straw disposal. Uneven crop maturity may occur from applications made to crops under stress due to drought, disease or excessive heat. Do not treat patches or areas of the crop that are late maturing due to any cause (e.g., waterlogging or pigeon damage). Do not treat crops that have a significant number of secondary re-growth shoots. Apply in 100 – 250 litres of water per ha by means of a hydraulic nozzle sprayer – use a higher volume within this range where the crop canopy and/or weed foliage is dense. Do not apply with a rotary atomiser sprayer. Select the correct application rate according to the weed species to be treated, weed population or situation as in the table below

Combining Pea, Field Beans 
Apply when the moisture of the grains (crop seeds) is below 30% and at least 7 days before harvest. Make an accurate measurement of seed moisture prior to application. Observe the latest time of application of 7 days before harvest. 
DO NOT TREAT CROPS GROWN FOR SEED. 
Apply using a high-clearance tractor fitted with narrow wheels and crop dividers to minimise crop damage. Not for use as a crop desiccant treatment. Apply in 80 – 250 litres of water per ha by means of a hydraulic nozzle sprayer – use a higher volume within this range where the crop canopy is dense. Alternatively apply in a minimum of 40 litres of water per ha using a rotary atomiser sprayer ensuring that the spray droplet spectrum is in the range of a Volume Median Diameter (VMD) of 200 – 300 microns. Select the correct application rate according to the weed species to be treated, weed population or situation as in the table below.

Linseed 
Apply when the moisture of the grains (crop seeds) is below 30% and at least 14 days before harvest. Make an accurate measurement of seed moisture prior to application. The seed pods will usually be brown, the seeds light brown, and the plant leaves and stems yellow-green to green in colour. An interval of up to 4 weeks may be required before the crop can be harvested by direct combining. Weeds may not be susceptible from applications made in the autumn – see “Weed Control”. 
DO NOT TREAT CROPS GROWN FOR SEED. 
Apply in 80 – 250 litres of water per ha by means of a hydraulic nozzle sprayer – use a higher volume within this range where the crop canopy is dense. Do not apply with a rotary atomiser sprayer. Select the correct application rate according to the weed species to be treated, weed population or situation as in the table below.

Treatment of Stubbles of all Crops or Cultivated Land prior to Sowing or Planting any Crop except Orchards (see Separate Section “Orchards”)
Control of Common Couch, other Perennial Grasses and Volunteer Potatoes (Autumn) in Stubbles of all Crops
Rosate 36 can be applied to the stubbles of all crops in the autumn or spring for the control of Common Couch, other perennial grasses and volunteer potatoes, prior to cultivation and sowing or planting of any crop. The ground must not be cultivated prior to application. Leave an interval of at least 5 days before and after application. Volunteer potatoes (autumn application only) must have a significant amount of top growth at application. For spring applications allow a minimum of 21 days of weed growth prior to application. Apply in 80 – 250 litres of water per ha by means of a hydraulic nozzle sprayer – use a higher volume within this range where the crop canopy is dense. Alternatively, apply in a minimum of 40 litres of water per ha using a rotary atomiser sprayer ensuring that the spray droplet spectrum is in the range of a Volume Median Diameter (VMD) of 200 – 300 microns. Select the correct application rate according to the weed species to be treated, weed population or situation as in the table below.

Control of Volunteer Cereals, Annual Grasses and Annual Broad-leaved Weeds in Stubbles of all Crops or on already Cultivated Land prior to Sowing or Planting any Crop
Rosate 36 can be applied to the stubbles of all crops prior to cultivation or to already cultivated land in the autumn or spring for the control of Volunteer cereals, annual grasses and annual broad-leaved weeds prior to cultivation and sowing or planting of any crop. Land may be cultivated after an interval of at least 24 hours has elapsed after application. Land can be direct drilled after an interval of at least 2 days has elapsed after application. Apply in 80 – 250 litres of water per ha by means of a hydraulic nozzle sprayer – use a higher volume within this range where the crop canopy is dense. Alternatively, apply in a minimum of 40 litres of water per ha using a rotary atomiser sprayer ensuring that the spray droplet spectrum is in the range of a Volume Median Diameter (VMD) of 200 – 300 microns. Apply Rosate 36 at 1.5 litres per ha and for best results add a suitable authorised adjuvant. Do not use an adjuvant when applying through a rotary atomiser sprayer

Destruction of Established Grassland with Weed Control prior to Re-seeding, Planting or Sowing
Rosate 36 can be used for the destruction of established grassland and weeds present in the sward prior to re-seeding, planting or sowing new grassland or any other crop. Apply to grass re-growth after grazing or cutting. Alternatively, apply before grazing or cutting between June – October to grassland 30 – 60 cm high that is not dense and before maturity of grass seeds. Grassland crops can be used in the normal manner after 5 days have elapsed after application, including grazing by or feeding to cattle, dairy cows or sheep. THE FOLIAGE OF ANY POISONOUS WEEDS (SUCH AS RAGWORT) MUST BE REMOVED OR BURIED PRIOR TO GRAZING OR CUTTING FOR FEED. Following removal of the grass crop, normal cultivations may be carried out in preparation for planting or sowing the following crop. DO NOT APPLY any fertiliser or lime application prior to application of Rosate 36. Apply in 150 – 250 litres of water per ha by means of a hydraulic nozzle sprayer – use a higher volume within this range where the grass canopy or weed foliage is dense. Do not apply with a rotary atomiser sprayer. Select the correct application rate according to the grassland situation to be treated as in the table below and according to the rate required for the control of the least susceptible weed species present in the sward – see “Grassland Weed Control” below

Hard Surfaces, Natural Surfaces not intended to bear Vegetation, Permeable Surfaces Overlying Soil
Apply in 80 – 400 litres of water per ha by means of a hydraulic nozzle sprayer – use a higher volume within this range where the weed foliage is dense. Alternatively, apply in a minimum of 40 litres of water per ha using a rotary atomiser sprayer ensuring that the spray droplet spectrum is in the range of a Volume Median Diameter (VMD) of 200 – 300 microns. Rosate 36 may be used for the control of unwanted vegetation in non-crop areas such as roadsides, paths, hard surfaces and along fence lines, walls and similar situations in amenity and industrial areas. People, domestic pets and wildlife do not need to be excluded from the treated area. However, to avoid direct transfer of the wet spray onto desired vegetation, it is advisable not to walk in the treated area until the spray is dry on the foliage. 
DO NOT USE IN OR ALONGSIDE HEDGEROWS. 
DO NOT USE UNDER GLASS OR POLYTHENE. 
Select the correct application rate according to the weed species to be treated, weed population or situation as in the table below.

Orchards
Rosate 36 may be used on land that is to be planted to orchard (top fruit) or in established orchards.

Land to be planted to Orchard with Top Fruit Trees 
Apply in 200 – 250 litres of water per ha by means of a hydraulic nozzle sprayer – use a higher volume within this range where the weed foliage is dense. Alternatively apply in a minimum of 40 litres of water per ha using a rotary atomiser sprayer ensuring that the spray droplet spectrum is in the range of a Volume Median Diameter (VMD) of 200 – 300 microns. Select the correct application rate according to the weed species to be treated, weed population or situation as in the table below.
All top fruit crops may be planted after 7 days have elapsed after treatment.

Established Apple, Pear, Plum, Damson and Cherry Orchards
Apply in 200 – 400 litres of water per ha by means of a hydraulic nozzle sprayer – use a higher volume within this range where the weed foliage is dense. Do not apply with a rotary atomiser sprayer. Timing: apply after trees have lost their leaves in the autumn, but before the green cluster stage in apples and pears, and before the white bud stage in plums, cherries and damsons. Do not use until after trees have been established for 2 years. Avoid spray coming into contact with tree branches and tree trunks at a height of over 30 cm above the ground. Do not make more than 1 application per year.

Wheat, Barley, Oats, Oilseed Rape, Combining Pea, Field Bean, Mustard, Linseed, Sugar Beet, Swede, Turnip, Bulb Onion and Leek
Rosate 36 may be used as a post-sowing, pre-crop emergence treatment for the control of volunteer cereals and annual weeds on land planted with wheat, barley, oats, oilseed rape, combining pea, field bean, mustard, linseed, sugar beet, swede, turnip, bulb onion and leek. APPLICATION MUST BE MADE PRIOR TO ANY CROP EMERGENCE. Apply 1.5 litres per ha of Rosate 36 in 80 – 250 litres of water per ha by means of a hydraulic nozzle sprayer. Alternatively, apply in a minimum of 40 litres of water per ha using a rotary atomiser sprayer ensuring that the spray droplet spectrum is in the range of a Volume Median Diameter (VMD) of 200 – 300 microns.

SPRAYER DECONTAMINATION 
Trace amounts of Rosate 36 remaining in the sprayer after use can cause damage to other crops subsequently treated with the same equipment. Immediately after use, thoroughly clean the sprayer and all equipment with a proprietary detergent cleaner. It is essential that all nozzles, filters, tubing, strainers, pumps and the spray tank are thoroughly cleaned after use to avoid the risk of damage to crops subsequently treated with the same equipment.

COMPATIBILITY
