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.
Warnings
EXTREME CARE SHOULD BE TAKEN TO AVOID SPRAY DRIFT AS THIS CAN SEVERELY DAMAGE NEIGHBOURING CROPS OR PLANTS. DO NOT MIX, STORE OR APPLY ROUNDUP PROBIACTIVE 450 IN GALVANISED OR UNLINED STEEL CONTAINERS OR SPRAY TANKS. DO NOT leave spray mixtures in tank for long periods and make sure tanks are WELL VENTED.
Restrictions
A period without rain of at least 6 hours, and preferably 24 hours, must follow application of Roundup ProBiactive 450 herbicide.
Do not spray on to weeds suffering from drought, water-logging, heat or frost, otherwise poor control may result.
Do not spray in windy conditions as drift onto desired plants or crops could severely damage or destroy them.
Do not tank mix Roundup ProBiactive 450 with adjuvants, pesticides or fertilisers except as specified under Directions for Use – Compatibility.
Applications of lime, fertiliser, farmyard manure and pesticides should be delayed until 5 days after application of Roundup ProBiactive 450.
Keep stock out of treated areas for 7 days to allow herbicide to become fully active. TREATED POISONOUS PLANT SPECIES MUST BE REMOVED BEFORE REGRAZING OR CONSERVING.
Weeds controlled
Amenity, Orchards, Forestry & Industrial
Roundup ProBiactive 450 herbicide controls most emerged grasses and broad-leaved weeds. It is important that all weeds are at the correct growth stage when treated, otherwise some re-growth may occur and this will need re-treatment Apply Roundup ProBiactive 450 herbicide where there is full emergence of grasses and broad-leaved weeds and they have ACTIVELY GROWING green leaves.
PERENNIAL GRASSES must have full emergence of healthy, green leaf. (Common Couch, for example, becomes susceptible at the onset of tillering and new rhizome growth, which usually occurs when plants have 4-5 leaves, each with 10-15 cm of new growth). PERENNIAL BROAD-LEAVED WEEDS are most susceptible around the flowering stage. ANNUAL GRASSES AND BROAD-LEAVED WEEDS should have at least 5 cm of leaf, or 2 expanded true leaves, respectively.
BRACKEN should be treated after frond tips are unfurled, but pre- senescence. Roundup ProBiactive 450 will not give an acceptable level of control of Horsetails (Equisetum arvense) – repeat treatment will be necessary.
Aquatic
AQUATIC WEEDS should be treated when the weeds are actively growing with full emergence of green leaf, at flowering and before dieback. Best results are obtained from applications in the periods from mid-July to mid-August on Water-lily and mid-August to mid-September on reeds.
OTHER SPECIES - recommendations for specific areas of use are given in the Recommendation Tables,
Following crops (Subsequent land use following application of Roundup ProBiactive 450)
Upon soil adsorption the herbicidal properties of Roundup ProBiactive 450 are lost permitting the drilling of crops 48 hrs after application. Planting of trees, shrubs, etc. may take place 7 days after application. Grass may be sown 15 days after treatment.
Users must consult the appropriate water regulatory body (Environment Agency/Scottish Environmental Protection Agency) before using the product near water and must obtain their agreement before using this product to control aquatic weeds. The maximum concentration of active substance in treated water should not exceed 0.04 ppm. When applying through conventional rotary atomisers, 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: (a) Weed wiper mini - 1:2.75 dilution with water (b) Other wipers - 1:1.5 dilution with water For stump application, the maximum concentration must not exceed 160 ml of product per litre of water (i.e. a 16% solution).
Roundup ProBiactive 450 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 Pro Biactive may also be used as a directed spray in ornamental plantings, orchards and for spot treating weeds in grassland. Roundup Pro Biactive must be targeted only at weed growth on hard surfaces such as roadsides and paths, (see recommendation table for details).
Correctly calibrate all sprayers under field or use conditions prior to application.
a) Conventional Hydraulic Sprayers
Knapsack sprayers and tractor mounted or powered sprayers may be used. These should be capable of applying accurately 80-400 l/ha within a pressure range of 1.5-2.5 bars (20-35 psi).
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. Nozzles producing a medium or coarse spray (BCPC definition) should be used to minimise the risk of drift : eg. Knapsack Lurmark AN 2.0, AN 4.0 Cooper Pegler Floodjet green, red Tractor Lurmark 04-F110, 08-F110 Tee Jet 11004, 11008.
Low Volume Application (minimum 80 l/ha)
Low volume application can be achieved by reducing pressure and appropriate nozzle selection. Low drift nozzles which produce a medium spray (BCPC definition) should be used to minimise the risk of drift, eg. Knapsack Cooper Pegler VLV 100 Lurmark AN 1.0 Tractor Lurmark Lo Drift.
Filling the Sprayer
Knapsack
Half fill the spray tank with clean water, add the correct amount of Roundup ProbBiactive 450 and top up with water. Mix thoroughly.
Tractor Mounted
To avoid foaming do not use top tank agitation. Half fill the spray tank with clean water, start gentle agitation, then add the correct amount of Roundup ProBiactive 450. Top up the tank with water to the required level. Use of a defoamer may be necessary.
b) Rotary Atomisers (hand held or tractor mounted) – for use in amenity, industrial forestry, orchards and aquatic areas. When conventional rotary atomisers are used to apply Roundup ProBiactive 450 ensure that the droplet diameter falls within the range 200-300 microns for all uses. Roundup ProBiactive 450 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.
c) Hand-held Wipers – for amenity,orchards, industrial and aquatic areas Roundup ProBiactive 450 may be applied through the weed wiper mini. Use a concentration of 1 part Roundup ProBiactive 450 to 2.75 parts of water and add a scarlet dye if required. Care should be taken to avoid dripping onto wanted vegetation. A suitable dye may be obtained from Certis, telephone (01980) 676500.
d) Cut Stump Application Enso attachment to rotary saws: This technique is specific to scrub clearance in forestry. A water-soluble dye may be added to Roundup ProBiactive 450 to help identify treated stumps.
HAND-HELD EQUIPMENT: SPECIFIC GUIDANCE
e) Knapsack Sprayer Applicators – for use in forestry, industrial, orchards and aquatic areas. When used at a walking speed of 1 m/sec to apply a swath of 1 m width, most knapsack sprayers deliver 200 l/ha spray volume (or 10 litres per 500 m²). To apply 3.2 l/ha of Roundup ProBiactive 450, therefore, use a 1.6% solution (e.g. 160 ml Roundup ProBiactive 450 made up to 10 litres). When used as above, knapsack sprayers fitted with low volume nozzles typically deliver 100 l/ha spray volume (or 10 litres per 1000 m²). To apply 3.2 l/ha Roundup ProBiactive 450 in this case, use a 3.2 % solution.
Filling the sprayer - hand-held machines Stir the correct amount of Roundup ProBiactive 450 into the sprayer half filled with clean water. Top up with water, close the top and shake gently to ensure good mixing.
f) Spot Gun Applicators – for treatment of individual weeds Apply 4 ml of spray to target weed, using a narrow cone TG-3 or TG-5 nozzle.
Roundup ProBiactive 450 is compatible with Mixture B NF (ADJ 0570). Where conventional hydraulic sprayers are being used Mixture B 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 ProBiactive 450 with adjuvants, pesticides or fertilizers except as advised by Monsanto. For up to date information on compatible products contact Monsanto UK Limited (tel: 01954 717575). Do not tank-mix Roundup ProBiactive 450 when using rotary atomiser sprayers. For hydraulic sprayers: maintain continuous agitation when using Roundup ProBiactive 450 in tank mixture. For knapsack sprayers: mix thoroughly and use immediately when using Roundup ProBiactive 450 in tank mixture.
Roundup ProBiactive 450 is an advanced glyphosate formulation which, having no hazard classification, offers a high standard of operator safety. To maximise the intrinsic safety of Roundup ProBiactive 450 to operator, consumer and environment, the label recommendations and the DEFRA/HSC/NAWPCD publication "Code of Practice for Using Plant Protection Products” of January 2006, should be adhered to. Roundup ProBiactive 450 herbicide is a foliar-acting herbicide with broad-spectrum activity. It is taken up by foliage and translocated to underground roots, rhizomes and stolons, providing control of both annual and perennial grasses and broad-leaved weeds. Roundup ProBiactive 450 is rapidly adsorbed onto particulate matter in soils and water and is quickly degraded by the microorganisms present in soil and aquatic bottom sediments. Upon adsorption, the herbicidal properties of Roundup ProBiactive 450 are lost, permitting drilling of crops within 48 hours of application. When used as directed, any water subjected to Roundup ProBiactive 450 spray drift may be used immediately for irrigation purposes. Until degraded, the active ingredient in Roundup ProBiactive 450, glyphosate, is practically immobile in soils and is, therefore, unlikely to contaminate groundwater. Roundup ProBiactive 450 is recommended for control of annual and perennial weeds in non-crop areas such as roadsides, paths, hard surfaces and along fences and walls. It is recommended for cleaning up weedy ground prior to planting or sowing, for total weed control on industrial sites and for aquatic weed control. Roundup ProBiactive 450 may also be used as a directed spray in ornamental plantings, and in forestry for site preparation and post-planting treatments.
Symptoms of treatment are generally first seen 7-10 days, or longer (if growth is slow), after spraying. These take the form of leaf reddening followed by yellowing and are usually quicker to appear on grasses than on broad-leaved weeds. Reaction of nettles 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.
Glyphosate, the active ingredient in Roundup ProBiactive 450 is a Group H herbicide based on the mode of action classification system of the Herbicide Resistance Action Committee. Under Best Practice there is a low risk for the development of weed resistance to Roundup ProBio. 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.
