Roundup Powermax

Monsanto - herbicide

A foliar applied herbicide for the control of annual and perennial grass and broad-leaved weeds, before sowing or planting all crops, pre-emergence and pre-harvest in cereals and certain other crops, for destruction of grassland, and set-aside and for use in stubbles, orchards, vineyards, forestry, industrial, horticultural, aquatic and non-crop areas.

Degraded by micro-organisms/microbes in the soil. This product contains a water soluble granule (WG) containing 720.0 g/kg glyphosate

ROUNDUP POWERMAX is a foliar-acting herbicide with broad-spectrum activity. It is translocated, after absorption, from treated green growth to underground roots, rhizomes and stolons, providing control of both annual and perennial weeds. Applied pre-harvest of specified crops, ROUNDUP POWERMAX provides, in addition to weed control, a diverse range of harvest management benefits accruing from the removal of green material from the crop.
ROUNDUP POWERMAX is a water-soluble granule formulation with very superior handling characteristics. The free-flowing, dust-free granules dissolve rapidly and completely in water. Because the bulk density of this granular formulation is very stable, ROUNDUP POWERMAX may be measured both by weight, or volume, as required.
ROUNDUP POWERMAX is an advanced granular glyphosate formulation. In addition to being approved pre-harvest in specified crops and grassland, ROUNDUP POWERMAX is of exceptionally low toxicity to mammals, fish, birds, beneficial insects and both terrestrial and aquatic invertebrates. ROUNDUP POWERMAX 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. Upon adsorption, the herbicidal properties of ROUNDUP POWERMAX are lost, permitting drilling of crops within 24 hours of application. Prior to degradation, the active ingredient in ROUNDUP POWERMAX, glyphosate, is practically immobile in soils and is, therefore, unlikely to contaminate groundwater sources

Weed Susceptibility
All target weeds must be actively growing at spraying: PERENNIAL GRASSES must have full emergence of healthy, green leaf. (Scutch, 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 have unfurled.

Weed resistance strategy
There is low risk for the development of weed resistance to ROUNDUP POWERMAX. A strategy for preventing and managing weed resistance should be adopted. This should include integrating herbicides with a programme of cultural control measures. 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
The adoption of complimentary weed control practices
Minimising the risk of spreading weed infestations
The implementation of good spraying practice to maintain effective weed control
Using the correct nozzles to maximise coverage
Application only under appropriate weather conditions
Monitoring performance and reporting any unexpected results to Monsanto Ireland (Tel: (01) 825 0555/825 0574)

Method of Application
Tractor mounted/trailed sprayer/knapsack/weedwiper/boat mounted hydraulic sprayer

Spray Quality
A MEDIUM or COARSE quality spray should be applied, using either a conventional hydraulic or rotary atomiser sprayer. This is best achieved within a pressure range of 1.5 to 2.5 bar.

Filling the Sprayer
Fill the spray tank with water until the re-circulation outlet is submerged and start agitation. Add the appropriate quantity of ROUNDUP POWERMAX. Top up the tank to the level required.

When using a chemical induction bowl or hopper, half fill the bowl with water and add ROUNDUP POWERMAX until within 2 cm (1 inch) of the surface of the water. With the rinsing system on, open the valve to empty the bowl into the main tank. Repeat until the required amount of ROUNDUP POWERMAX has been introduced.

Sprayer Hygiene
It is essential to thoroughly clean out the entire sprayer system, using a recommended detergent cleaner, between ROUNDUP POWERMAX and other pesticides.

ROUNDUP POWERMAX is compatible with the following herbicides: Butisan S Venzar Flowable Starane (add to tank first) N.B. Ensure and maintain continuous agitation when using ROUNDUP POWERMAX in tank-mixture with these herbicides. Always consult manufacturer’s recommendations before use.
Do not tank-mix ROUNDUP POWERMAX when using rotary atomiser sprayers.

Hand-held equipment: specific guidance
Wear suitable protective clothing (coveralls), suitable gloves and rubber boots when using hand-held rotary atomisers, weed-wipers and spot gun

Knapsack sprayer applicators (for use in non-crop areas): When used at a walking speed of 1 metre/second to apply a swath of 1 metre width, most knapsack sprayers deliver 200 l/ha spray volume (or 10 litres per 500m2 ).
Do not tank-mix ROUNDUP POWERMAX with adjuvants, pesticides or fertilisers, except as specified under ‘Tank-mixtures’ section.
To apply 2.0 kg/ha of ROUNDUP POWERMAX, therefore, use 20 g product for each 2 litres of spray liquid required.
Weedwiper applicator (e.g. Weedwiper Mini) (for use in non-crop areas)
Apply a solution of 265 g ROUNDUP POWERMAX per 1 litre of water

Applications of lime, fertiliser, farmyard manure and pesticides should be delayed until 5 days after application of ROUNDUP POWERMAX. Do not tank-mix ROUNDUP POWERMAX with adjuvants, pesticides or fertilisers, except as specified under ‘Tank-mixtures’ section. Reduced control is likely where weed growth is impaired by natural senescence, drought, high temperature, a covering of dust, flooding or severe/prolonged frost at, or immediately after application. Take extreme care when using near or alongside hedgerows. A rain-free period of at least 6 hours should follow application. After application, large concentrations of decaying foliage, stolons, roots or rhizomes should be dispersed or buried by thorough cultivation before crop drilling.
