Revenge 20 is a post-emergence systemic herbicide for the control of certain broad leaved weeds in winter wheat, spring wheat, (including durum wheat), winter barley, spring barley, winter oats, spring oats, triticale, linseed and land temporarily removed from production (set-aside).

After application, Revenge 20 is translocated through the weed plant. Weed growth is stopped or slowed shortly after application and this minimises the effects of weed competition on the crop. Final death of susceptible weeds and the decay of weed foliage may not be seen until several weeks after treatment. Revenge 20 is typically rainfast 1 hour after application under good drying conditions.

 

Do not treat crops that are or have been under stress from any cause, including poor soil or cultural conditions, adverse climatic conditions, waterlogging or drought, pest or disease attack, nutrient deficiency, or any other cause

Apply Revenge 20 when the weeds are growing actively. Best results will be achieved from applications made when the weeds are small. The crop should be growing strongly and provide competition with the weeds.

Do not spray if frost is likely to occur soon after spraying, during periods of frosty weather, or during periods of low night temperatures.

Do not roll or harrow or make any other cultivation within 1 week before or after application. Weed foliage should be dry at the time of application; do not apply when rain is imminent. Do not apply more than once to any crop.

Do not allow spray bouts to overlap.

Do not use on cereal crops undersown or due to be undersown with grass, clover (or other legumes) or any broad-leaved crop.

Contract agents should be consulted before using on crops grown for seed

Before use, make sure the sprayer is calibrated to apply the recommended spray volume and pressure. Immediately after use thoroughly clean the sprayer and all equipment – see “Sprayer Decontamination”. Traces of product left in the sprayer may cause damage to other crops that are subsequently treated with the same equipment.

 

There is a significant risk for the development of weed resistance to Revenge 20.

Strains of some annual weeds 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

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. Consider using sequences or tank-mixing with suitable products having a different mode of action.

Apply only under appropriate weather conditions.

Monitor herbicide performance and report any unexpected results to Agform Ltd

 

Revenge 20 is active at very low application rates. Take extreme caution not to allow spray to drift and contaminate any broad-leaved plants, (or soil to be planted with broad – leaved plants) lying outside the target sprayed crop area

Avoid damage by drift onto ponds, waterways or ditches. Draining or flushing of spraying equipment must not take place on land planted or intended for planting with trees or any crop other than cereals

Soil Types and Conditions

Revenge 20 may be used on all soil types. Weed control will be reduced under dry soil conditions

Application Rate

Revenge 20 is highly active and only very low application rates are required. Make one application of 30 g/ha to all recommended crops. Observe the maximum individual dose, maximum number of treatments and latest time of application as specified under “Crops Treated”

Crops Treated

 

All varieties of winter and spring wheat (including durum wheat), and winter and spring oats may be treated with Revenge 20 from the 2 leaf stage until GS 39 (before the flag leaf sheath extending stage). All varieties of winter and spring barley may be treated from the 3 leaf stage until GS 39 (before the flag leaf sheath extending stage).

Apply after the 31st January and within the recommended crop growth stages. For optimum weed control, apply when the weeds are small and actively growing, preferably during a period of mild weather, see “Weed Control”.

MaximumDose:                30g/ha.

Maximum number of treatments:                   One percrop

Apply in 100 – 400 litres of water per hectare. Select a volume of water from within this recommended range that will give a good even cover of the weed foliage, use the higher volume when crops or weed populations are dense. Good spray cover is essential to achieve the weed control indicated (see Weed Control).

 

Revenge 20 may be applied in tank mixture to winter wheat, winter and spring barley with approved formulations of any one of the following formulations:

Chlormequat, fluroxypyr, bromoxynil/ioxynil, mecoprop-p, amidosulfuron, clodinafop-propargyl with adjuvant, fenoxaprop-p-ethyl with adjuvant

Before using any tank-mix, always follow the manufacturer’s restrictions and recommendations for the partner product.

When making a tank-mix, add each product separately to the water in the spray tank or mixing bowl and agitate thoroughly before adding the partner product. Always add the Revenge 20 to the spray tank first

Do not apply the mixture with fluroxypyr to spring cereals.

DO NOT APPLY SAVVY CLEAR IN MIXTURE WITH ANY OF THE FOLLOWING:-

chlorpyrifos

any product containing diclofop-methyl any product containing flutriafol

any product containing propiconazole tralkoxydim with adjuvant

At least 14 days must elapse between application of Revenge 20 and any of the products listed above

When Revenge 20 is applied in a tank-mix with an approved formulation containing amidosulfuron, sow only any cereal crop as the following crop. Do not apply Revenge 20 in any tank-mixture on spring wheat, oats and triticale.

 

Winter wheat crops that have been treated with one of the sulfonylurea products listed below may be treated in sequence with Revenge 20:

Do not apply Revenge 20 to any cereal crop in sequence or in tank mixture with a product containing any other sulfonylurea or ‘ALS-inhibiting’ herbicide.

Do not apply Revenge 20 to any crop following the use of any other sulfonylurea herbicides

The above products must be applied in accordance with the manufacturer’s recommendations. After harvesting a crop treated with a sequence of one of the above products and Revenge 20 in the spring, plant only winter wheat as the following crop.

 

All varieties of linseed (including crops for seed) may be treated with Revenge 20. Apply after the 31st January when the crop is actively growing and from the first pair of true leaves unfolded stage, up until the crop is 30 cm high or before flower buds are visible, whichever occurs first.

Do not apply to crops of linola or flax.

Do not apply in tank-mix with any other product or in sequence with any other sulfonylurea containing product.

Ensure an interval of at least 7 days (10 days if the crop is growing poorly or under stress) before and after application of Revenge 20 and the application of any other crop protection product.

Some stunting of the crop may occur especially under conditions of frost, heavy rainfall, significant day/night temperature variations, or any combination of these factors. Crop yield may be reduced in severe cases

MaximumDose:                30g/ha.

Maximum number of treatments:                   One percro

Apply in 100 – 200 litres of water per hectare. Select a volume of water from within this recommended range that will give a good even cover of the weed foliage; use the higher volume when crops or weed populations are dense. Good spray cover is essential to achieve the weed control indicated (see Weed Control).

For optimum weed control, apply when the weeds are actively growing and small, preferably during a period of mild weather, see “Weed Control”. Weed control may be reduced if soil conditions are very dry

Following harvesting, only cereals may be sown within 16 months of the date of treatment.

Green cover on land temporarily removed from production

Revenge 20 may be applied to green cover on land temporarily removed from production (set-aside) for the control of broad-leaved weeds, provided that a full green cover is has been established and where the green cover crop is predominantly (i.e. sufficient to maintain reasonable cover) grassland, wheat, barley, oats or triticale. For optimum control of Docks, apply 3 weeks before or after cutting. Since other broad-leaved species will also be controlled, the use of Revenge 20 may not be applicable in areas being managed for conservation or wildflower development.

Before use on green cover on land temporarily removed from production, make sure that any application complies with any rules and stipulations under grant programmes or other management considerations

 

MaximumDose:                30g/ha.

Maximum number of treatments:                   One percrop

Apply in 200 litres of water per hectare. Good spray cover is essential to achieve good levels of weed control. For optimum weed control, apply when the weeds are small, from between the 15th April up until the 31st July, preferably during a period of mild weather (see Weed Control).

Do not make more than one application of any product containing a sulfonylurea in any calendar year.

Where the green cover crop is mainly made up of established grass species, some stunting and discolouration of the cover crop may occur

Do not use on seedling grasses.  Seedling cereals are tolerant after the 3-leaf stage.

After application to set-aside, only cereals may be sown within 16 months of the date of treatment

Method of Application

Apply as a MEDIUM spray (BCPC) by means of a conventional downward-placement hydraulic nozzle tractor-mounted or trailed sprayer (with or without air-assistance). Ensure that the sprayer is correctly calibrated to apply the recommended water volume and spray quality, and the boom height and nozzles are adjusted to give even coverage of the target weeds. Avoid overlapping of spray bouts

 

Before use ensure the sprayer is clean and decontaminated from any previous use. Place a quarter of the required amount of clean water in the spray tank and commence agitation. Add the required amount of Revenge 20, followed by the remaining water requirement and use immediately. Continue agitation during spraying; do not allow the spray mixture to sta

When Revenge 20 is tank-mixed with a partner product, always add the partner product(s) to the spray tank after the Revenge 20

Ensure that all completely used containers are empty, and dispose of according to the MAFF/HSE Code of Practice for the Safe Use of Pesticides on Farms and Holdings. After use, clean and decontaminate the sprayer and all equipment.

 

If a crop treated with Revenge 20 fails for any reason, only sow winter wheat within 3 months of the date of treatment

Following harvesting of a cereal crop treated with Revenge 20, only oilseed rape, cereals, field beans or grass may be sown in the same calendar year as the year of treatment. Any crop can be sown the next year.

Following harvesting of a linseed crop treated with Revenge 20, or after application to set-aside, only cereals may be sown within 16 months of the date of treatment.

Sow only wheat, barley, rye or triticale following a cereal crop treated with Revenge 20 and any product containing imazamethabenz-methyl

Sow only wheat, barley, rye or triticale following a cereal crop treated with a tank mixture of Revenge 20 and an approved formulation containing amidosulfuron

Sprayer Decontamination

Immediately after use, the sprayer and all other equipment must be thoroughly cleaned and decontaminated to stop any traces of Revenge 20 remaining in the sprayer and causing damage to crops treated subsequently with the sprayer.

Thoroughly clean and decontaminate the sprayer internally and externally by brushing and rinsing with cleaning water, including the lid, booms, nozzles, nozzle filters, in-line filters and all other equipment

Nozzles, nozzle and all other filters and strainers should be removed from the sprayer and cleaned separately. Fill the sprayer to at least 10% of the tank volume and pump through, making sure there is sufficient pressure to adequately flush the system. Any remaining rinsate must be drained out of the tank and the rinsing, flushing and draining procedure repeated

If Revenge 20 is applied in a tank-mix with an approved formulation containing amidosulfuron, the following sprayer decontamination procedure must be followed:

 

Drain the sprayer and clean the outside to remove any contamination. Rinse the inside of the tank with water and flush through the booms, hoses and nozzles using clean water to fill at least 10% of the tank volume, then drain the tank until completely empty

Half fill the spray tank with clean water and add a proprietary tank cleaner mixture of ammonia formulated for sprayer decontamination in accordance with the manufacturer’s recommendations. As an alternative, use 0.3 litres of domestic ammonia solution (typically 9% strength) per 100 litres of tank capacity (or equivalent to give a final strength in the sprayer of 0.03%). Agitate and then flush the boom, hoses and nozzles with the solution and drain.   Fill the tank with clean water and agitate for a minimum of 15 minutes. Flush the hoses and boom and drain until empty. (If the tank does not empty completely, repeat the procedure using fresh proprietary tank cleaning mixture or household ammonia as above).

 

Remove the sprayer nozzles and all filters, clean and soak in a solution of proprietary tank cleaner or household ammonia of 0.03% as used in the sprayer.

Follow the Code of Practise for the Safe Use of Pesticides on Farms and Holdings for the disposal of sprayer and tank washings. Do not spray onto land intended for cropping with sensitive crops.

Carry out a final rinse of the sprayer with clean water using a minimum of 10% of the tank volume and then flush through the boom and hoses, drain and leave to dry.
