AMENITY, INDUSTRIAL AND GENERAL WEED CONTROL
Exclusion Times
People, pets and wildlife need not be kept out of treated areas. It is best not to walk in areas where the spray is still wet as transfer to other vegetation may lead to unwanted damage to other foliage. Once the spray is dry this cannot occur.
Area of Use
Roundup ProVantage is recommended for control of annual and perennial grasses and broad-leaved weeds in non-crop areas, for cleaning up weedy ground prior to planting or sowing and for aquatic weed control. Roundup ProVantage may also be used as a directed spray in ornamental plantings, orchards and for spot treating in grassland. Roundup ProVantage must be targeted only at weed growth on hard surfaces such as roadsides and paths, (see recommendation table for details). Application Rate 1.0 to 4.5 litres/ha – refer to Recommendation Tables.
Mixing and spraying
Roundup ProVantage mixes readily with water and can be applied in spray volumes ranging from 10-400 l/ha using tractor mounted, knapsack, rotary atomisers and hand-held sprayers. Specialised 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 hydraulic 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 Roundup ProVantage. Top up the tank with water to the required level. To avoid foaming do not use top tank agitation. Use of a defoamer may be necessary.
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 minimise 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 minimise the risk of drift.
b) Knapsack sprayers
Recommended delivery range is 80 - 250 l/ha. Half fill the spray tank with clean water, add the correct amount of Roundup ProVantage and top up with water. Fill according to best practice as given on the CPA’s Voluntary Initiative website (www.vountaryinitiative.org.uk) When used at a walking speed of 1 metre/second to apply a swath of 1 metre width, most knapsack sprayers fitted with a Hypro AN 1.2 or similar nozzle deliver approximately 200 l/ha spray volume (or 10 l per 500 m2). To apply 3.75 l/ha of Roundup ProVantage, therefore, use a 1.9% solution, i.e. 190ml Roundup ProVantage made up to 10 litres. Similarly, knapsack sprayers fitted with low volume nozzles such as Hypro DT 1.5 typically deliver approximately 100 l/ha spray volume. To apply 3.75 l/ha Roundup ProVantage in this case use 3.75% solution.
c) Rotary Atomisers
Hand-held machines can be used to apply a spray volume of 10-40 l/ha, e.g. Herbi and Herbaflex. Tractor-mounted rotary atomiser boom sprayers are suitable for use in amenity, industrial, forestry, orchards and aquatic areas situations to apply a spray volume of 10-40 l/ha. When conventional rotary atomisers are used to apply Roundup ProVantage ensure that the droplet diameter falls within the range 200-300 microns for all uses. Roundup ProVantage may be applied neat through specialised ULV applicators which have drift reducing systems or at a spray volume of 10-40 l/ha through conventional rotary atomisers.
d) Weed Wipers
For ropewick applicators use a concentration of 1 part Roundup ProVantage to 3 parts of water and add a water-soluble dye if required. Care should be taken to avoid dripping onto wanted vegetation. For new generation weed wipers, use 1part Roundup ProVantage to 10 or 20 parts of water or as directed by manufacturer’s instructions. A list of machines is included in the Company Advisory section at the end of this label.
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 10cm diameter and two to three notches in trees above 10cm diameter. Use 1.5 ml of undiluted Roundup ProVantage per notch. Specialist stem injection equipment can be used to inject 1.5 mls Roundup ProVantage into hollow stems such as Japanese Knotweed and Giant Hogweed.
g) Spot Gun Applicators
Spot gun applicators are for the treatment of individual weeds. Apply 5ml of spray to target weed, using a narrow cone TG-3 or TG-5 nozzle.When used in paddocks keep livestock out of treated area until treated Ragwort or other poisonous weeds have either been removed or died down completely.
Boat mounted sprayers
For use in aquatic situations. Prepare sprayer as for knapsack sprayers (Section b above). Calibrate and spray at the lowest speed possible. Always apply against the direction of any current.
Compatibility
Roundup ProVantage is physically compatible with some other pesticides. For up to date information on compatible products contact Monsanto UK Limited (tel: 01954 717575) or visit www.monsanto-ag.co.uk .Roundup ProVantage is compatible with Mixture B NF (ADJ 0570). Where conventional hydraulic sprayers are being used Mixture B NF may be added to the spray tank solution, at a rate of 2% of the final water volume, for all pre-plant and post-plant directed sprays only. DO NOT APPLY WITH MIXTURE B NF TO EDIBLE CROPS, GRASSLAND OR AQUATIC WEEDS. Do not tank-mix Roundup ProVantage when using rotary atomiser sprayers. N.B. Maintain continuous agitation when using Roundup ProVantage in a tank-mixture. For knapsack sprayers: mix thoroughly and use immediately when using Roundup ProVantage in tank mixture. Always consult manufacturers' recommendations before use.
General Information
Roundup ProVantage herbicide is an advanced formulation containing glyphosate. Roundup ProVantage is taken up by foliage and translocated to Page 19 underground roots, rhizomes and stolons, providing control of both annual and perennial grasses and broad-leaved weeds. Roundup ProVantage is rapidly adsorbed onto particulate matter in soils and water and is quickly degraded by the micro-organisms present in soil and aquatic bottom sediments. Until degraded, the active ingredient in Roundup ProVantage, glyphosate, is practically immobile in soils and is, therefore, unlikely to contaminate groundwater. Roundup ProVantage is a glyphosate formulation which, having no hazard classification, offers a high standard of operator safety. To maximise the intrinsic safety of Roundup ProVantage to operator, consumer and environment, the label recommendations and the DEFRA/HSE/NAW publication "Code of Practice for Using Plant Protection Products of January 2006 should be adhered to.
Symptoms on the weeds
Symptoms of treatment are generally first seen 7-14 days, or longer, if growth is slow after spraying. Leaf symptoms take the form of a reddening then yellowing of the foliage and are first seen on the grass weeds but take longer to appear on broad-leaved weeds. Reaction of nettle is slow. For aquatic weed control, on reeds and grasses leaf symptoms usually appear within 14-21 days of spraying in the early autumn. Complete foliage desiccation usually occurs 30-40 days after spraying. At this stage the reeds can be cut and removed. During cold conditions leaf symptoms may not appear before natural dieback but no growth will occur in the season following spraying.
Weed resistance
strategy Glyphosate, the active ingredient in Roundup ProVantage is a Group G herbicide based on the mode of action classification system of the Herbicide Resistance Action Committee. Page 20 Under Best Practice there is a low risk for the development of weed resistance to Roundup ProVantage. There are no known cases of weed resistance to glyphosate in UK. Strains of some annual weeds have developed resistance to glyphosate in some parts of the world leading 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 and /or active ingredients with a different mode of action.
