FORMULATION AND ACTIVE INGREDIENT: A soluble concentrate containing 485 g/L (41.5% w/w) of the isopropylamine salt of glyphosate (equivalent to 360 g/L glyphosate) and ethoxylated tallow amine surfactant. For the control of annual and perennial grasses and broad-leaved weeds before sowing and/or planting all crops. For use as a pre-emergence and pre-harvest herbicide in cereals and certain other crops, destruction of grassland, and in set-aside, orchards, stubbles, non-crop, forestry, industrial and amenity areas.

 

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. For use on “hard surfaces” only: apply this product carefully. Ensure spraying takes place only when weeds are actively growing (normally March to October) and is confined only to visible weeds including those in the 30cm swath covering the kerb edge and road gulley – do not overspray drains.

 

DO NOT MIX, STORE OR APPLY VIVAL IN GALVANISED OR UNLINED STEEL CONTAINERS OR SPRAY TANKS.

EXTREME CARE SHOULD BE TAKEN TO AVOID SPRAY DRIFT AS THIS CAN SEVERELY DAMAGE OR DESTROY NEIGHBOURING CROPS OR PLANTS.

DO NOT leave spray mixtures in tank for long periods and make sure tanks are WELL VENTED.

 

A period of at least 6 hours and preferably 24 hours rain-free must follow application of VIVAL.

Do not spray in windy conditions as drift onto desired crops or vegetation could severely damage or destroy them.

Do not spray onto weeds which are naturally senescent, or where growth is impaired by drought, high temperatures, a covering of dust, flooding or frost at, or immediately after application, otherwise poor control may result.

Applications of lime, fertilizer, farmyard manure and pesticides should be delayed until 5 days after application of VIVAL. After application, large concentrations of decaying foliage, stolons, roots or rhizomes should be dispersed or buried by thorough cultivation before drilling.

 

VIVAL is a foliar acting herbicide which controls annual and perennial grasses and most broadleaved weeds when used as directed. It is important that all weeds are at the appropriate stage when treated, otherwise some re-growth may occur which would need re-treatment.

Apply VIVAL herbicide once grasses and broad-leaved weeds have emerged and they have ACTIVELY GROWING green leaves.

PERENNIAL BROAD-LEAVED WEEDS are most susceptible at the flowering stage.

PERENNIAL GRASSES must have a full emergence of healthy, green leaf. For example, common couch becomes susceptible at the onset of tillering and when new rhizome growth commences, which usually occurs when plants have 4-5 leaves with 10- 15 cm of new growth.

ANNUAL GRASSES AND BROAD-LEAVED WEEDS should have at least 5 cm of leaf, or 2 expanded true leaves, respectively. In set-aside, annual grasses are best treated at full ear emergence, or before stem elongation. Application during the stem extension phase of annual grasses e.g. Black-grass and Brome species on set-aside between the end of April and end of May, may result in poor control and require re-treatment.

BRACKEN should be treated after frond tips are unfurled, but pre-senescence.

OTHER SPECIES – recommendations for specific Areas of Use are given in the recommendation Tables, pages 3-10. This product will not give an acceptable level of control of Horsetails (Equisetum arvense)

 

Until soil adsorption the herbicidal properties of VIVAL are lost permitting the drilling of crops 48 hours after application.

Planting of trees, shrubs etc may take place 7 days after application. Grass seed may be sown from 5 days after treatment. Refer to the ‘Recommendation Tables’ for specific restrictions on direct drilled crops.

 

There is low risk for the development of weed resistance to VIVAL.

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, crop advisor or product manufacturer, Belchim Crop Protection Ltd. Growers are encouraged to implement a weed resistance strategy based on (a) Good Agricultural Practices and (b) Good Plant Protection Practices by:

Following label recommendations

Monitoring performance and reporting any unexpected results to Belchim Crop Protection

Minimizing the risk of spreading weed infestations

The implementation of good spraying practice to maintain effective weed control  The adoption of complimentary weed control practices

Using the correct nozzles to maximize coverage

Application only under appropriate weather conditions

 

It is essential to thoroughly clean-out spray tanks, pumps and pipelines and nozzle or disc assemblies, with a recommended detergent cleaner, between applying this product and other pesticides to avoid contamination from pesticide residues. Traces of VIVAL left in the equipment may seriously damage or destroy crops sprayed later.

 

Other specific restrictions:
When applying through rotary atomizers the spray droplet spectra produced must be of a minimum Volume Median Diameter (VMD) of 200 microns. Weed wipers may be used in any recommended crop where the wiper or chemical does not touch the growing crop. For weed wiper applications, the maximum concentrations must not exceed the following: Weed wiper Mini 1:2 dilution with water Other wipers 1:1 dilution with water See Mixing and Spraying section For stump application, the maximum concentration must not exceed 200ml of product per litre of water (i.e. a 20% solution).

 

VIVAL mixes readily with water and can be applied in spray volumes ranging from 80-400 l/ha using tractor mounted, knapsack, rotary atomizers and hand-held sprayers. Specialized application equipment such as weed wipers, stem injection and spot gun applicators may be used where indicated. Correctly calibrate all sprayers under field or use conditions prior to application.

a) Tractor mounted and powered sprayers These should be capable of applying accurately 80-400 l/ha within a pressure range of 1.5-2.5 bars (20-35 psi). Half fill the spray tank with clean water, start gentle agitation, and then add the correct amount of VIVAL. Top up the tank with water to the required level. To avoid foaming do not use top tank agitation. Use of a de-foamer may be necessary. All applications using hydraulic sprayers (including knapsack sprayers) should use ‘MEDIUM’ or “COARSE’ spray quality (BCPC definition). Medium Volume application (150-300 l/ha) Avoid high water volumes (>300 l/ha) which may lead to run-off from the treated vegetation, resulting in reduced control. Low drift nozzles such as air induction and pre-orifice types producing a ‘MEDIUM’ or ‘COARSE’ spray (BCPC definition) should be used to minimize the risk of drift. Low Volume Application (minimum 80 l/ha) Low volume application can be achieved by reducing pressure and the appropriate nozzle selection. Low drift nozzles which produce a MEDIUM spray quality (BCPC definition) should be used to minimize the risk of drift.

b) Knapsack sprayers Recommended delivery range is 80-300 l/ha. Half fill the spray tank with clean water, add the correct amount of VIVAL and top up with water. Fill according to best practice as given on the CPA’s Voluntary Initiative website www.voluntaryinitiative.org.uk. When used at a walking speed of 1 m/sec to apply a swath of 1 m width, most knapsack sprayers fitted with a Lurmark AN 2.0 or similar nozzle deliver approximately 200 l/ha spray volume (or 10 L per 500 m2). To apply 4.0 l/ha of VIVAL, therefore, use 40 ml of product for each 2 litres of spray liquid required. Similarly, knapsack sprayers fitted with low volume nozzles such as Lurmark AN 1.0 typically deliver approximately 100 l/ha spray volume. To apply 4.0 l/ha VIVAL in this case, use 80 ml of product for each 2 litres of spray liquid required.

c) Rotary Atomizers Tractor-mounted boom sprayers and hand-held machines are suitable for use in some situations to apply a minimum spray volume of 40 l/ha. When rotary atomizers are used to apply VIVAL ensure that the droplet diameter falls within the range 200-300 microns for all uses. Stir the correct amount of VIVAL to control the particular target species into the sprayer bottle half filled with clean water. Top up with water, close the top and shake gently to ensure good mixing. Do not tank mix VIVAL when using rotary atomizer sprayers.

d) Weed Wipers For ropewick applicators use a concentration of 1 part VIVAL to 2 parts of water and add a watersoluble dye if required. Care should be taken to avoid dripping onto wanted vegetation. For new generation weed wipers, use 1 part VIVAL to 10 to 20 parts of water or as directed by manufacturer’s instructions.

e) Cut Stump Applicators For cut stump treatment an Enso attachment to rotary saws may be used. This technique is specific to scrub clearance in forestry. A suitable water soluble dye may be used.

f) Stem Injection Use a hatchet to cut one notch in trees up to 10 cm diameter and two to three notches in trees above 10 cm diameter. Use 2.0 ml of undiluted VIVAL per notch.

g) Spot Gun Applicators Spot gun applicators are for the treatment of individual weeds. Apply 5 ml of spray to target weed, using a narrow cone TG-3 or TG-5 nozzle.
