Dow AgroSciences - herbicide

A water in oil emulsion containing 30 g /litre (3.5% w/w) aminopyralid (present as 36 g/litre aminopyralid potassium) + 100 g /litre (14.14% w/w) fluroxypyr (present as 144 g/litre fluroxypyr-methyl heptyl ester).

For the control of a wide range of deep-rooted PERENNIAL and HERBACEOUS WEEDS on NON-CROP LAND such as motorway and railway embankments, roadsides, grassland of no agricultural interest, and industrial areas (but excluding airfields).

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.

Use of an antifoam is compulsory with this product.
Avoid damage by drift onto susceptible crops, non-target plants or waterways. Do not apply directly to, or allow spray drift to come into contact with agricultural or horticultural crops, amenity plantings, gardens, ponds, lakes or watercourses.

SENSITIVE PLANTS may be harmed by residues of SYNERO® in soil and treated vegetation. Do not apply SYNERO on or adjacent to soil which may be used as garden top-soil, potting soil, etc. or to grass which may be cut and used as mulch or for compost for horticultural or garden crops. Do not use cuttings from treated grass for mulching or composting.
Cut treated grass must not be removed from site, or used for animal feed, animal bedding, composting or mulching.
Treated grass must not be used for grazing.
On level ground there is negligible lateral movement but do not apply SYNERO around desirable trees or shrubs or where their roots may take up a lethal dose, care should be taken on slopes to prevent leaching into areas where desirable shrubs etc are present.

Grass and weeds must be actively growing to ensure good weed control and minimal check to the grass. Therefore do not spray in drought, very hot or very cold weather conditions.
Where a broadcast application is made to a high cover of Japanese knotweed and bramble, in season control may be variable. Control will be improved if a spot treatment is used for these target weeds. Where there is a high reservoir of weed seed in the soils and/or a historically high weed population, a programmed approach may be needed involving a further application in the following year.
Do not use on grass less than one year old.
Do not use on crops grown for seed.
Applications of SYNERO may lead to a slight leaning of the grass but this is transient.
SYNERO is safe to grass. Very occasionally some yellowing of the sward may occur; this is transient and quickly outgrown.
To allow maximum translocation of SYNERO to the roots do not cut grass for 7 days after application.
Clover will be killed by application of SYNERO.
Control may be reduced if rain falls within 1 hour of application.
Wash equipment thoroughly with water and detergent immediately after use

The timing of application of SYNERO is crucial. For good results the product must be applied to actively growing weeds at the correct growth stage as detailed in the WEED CONTROL section of this label.

Broadcast Treatmen
t SYNERO should be applied through a hydraulic sprayer provided it is in good working order and has been calibrated according to the manufacturers’ recommendations.

Use of an antifoam is compulsory with this product. Fill the spray tank half full with water and add required amount of SYNERO mixing well. Top up with water and continue agitation until the spray tank is full. Maintain agitation while spraying. Use the spray immediately

Spray Volume
For overall application SYNERO should be used in a spray volume of 200 litres of water per hectare to give good coverage of the weeds. A higher water volume of 250 - 400 litres of water per hectare may be required where the weed population is high and where the grass is dense at the time of application.

Spray Quality
Apply as a MEDIUM quality spray as defined by the BCPC system.

Spot Treatment
For localised treatment using a suitable lance from a knapsack or tractor mounted sprayer use a solution of 100 ml SYNERO per 10 litres of water. The weeds should be thoroughly wetted with the spray solution but spraying until "run-off" will decrease activity. The use of flood jets is recommended to prevent drift. Care should be taken to avoid local overdosing.
