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.
S Do not apply more than once to any cereal or linseed crop or more than once per year to land temporarily removed from production. When applying Savvy to linseed care should be taken no to overlap spray swaths. Savvy, alone or in tank-mix, must not be applied to any crop suffering from stress as a result of drought, waterlogging, low temperatures, pest or disease attack, nutrient or lime deficiency or other factors reducing crop growth. Do not use Savvy on cereal crops undersown with grasses, clover or other legumes or any other broad-leaved crop. Do not apply Savvy on seedling grasses. On green covers, Savvy should be applied to seedling cereals from the three-leaf stage. Do not apply Savvy to any crop in sequence or in tank mixture with a product containing any other sulfonylurea or 'ALS inhibiting' herbicides. When using tank-mixtures take care not to overlap spray swaths. Do not use Savvy in tank-mix on oats, triticale and linseed. On linseed allow at least 7 days between Savvy and other treatments (10 days if crop is growing
Savvy should not be applied within 7 days of rolling any crop. Due to the high level of activity of the herbicide, special care must be taken to avoid damage by drift onto broad-leaved plants outside the target area, or onto ponds, waterways or ditches. Thorough cleansing of equipment is also very important.
Savvy is a highly active herbicide with foliar and root activity against a wide range of broad-leaved weeds. It is most effective when applied to small actively growing weeds. As larger weeds often become less susceptible, it is important to note the size of each weed species at the time of application. Good spray cover of the weeds must be obtained. Weed control may be reduced when soil conditions are very dry. Nevertheless, with adequate soil moisture, susceptible weeds germinating soon after treatment will be controlled.
When herbicides with the same mode of action are used repeatedly over several years in the same field, selection of resistant biotypes can take place. These can propagate and may become dominating. A weed species is considered resistant to a herbicide if it survives a correctly applied treatment at the recommended dose. Development of resistance within a weed species can be avoided or delayed by sequencing or tankmixing with suitable products having a different mode of action. A strategy for preventing and managing resistance should be adopted. The Weed Resistance Action Groups have produced guidelines and copies are available from the HGCA, CPA, your distributor, crop adviser or product manufacturer.
Savvy can be used on all soil types.
Volume and application
Apply in 100 - 200 litres of water per hectare, using suitable equipment to give good spray cover of the weeds. When crops are thick or weed growth dense, use 400 litres of water per hectare. When applying Savvy, care should be taken not to overlap spray swaths
Before using Savvy, make sure that the spraying equipment is clean.
When using Savvy in a tank-mix, always add Savvy to the spray tank first. Savvy mixes easily with water, but the following mixing procedure should be followed: quarter fill the spray tank with water, start the agitation and add the required quantity of Savvy directly to the tank without prior creaming. Continue agitation while topping up the tank and while spraying
For information on tank-mixing partners contact your distributor. Do not apply Savvy to any cereal crop in tank mixture with a product containing any other sulfonylurea or 'ALS inhibiting' herbicides
Savvy can be used on all winter and spring varieties of wheat, oats, barley and triticale between the growth stages given below. Savvy may be applied to areas temporarily removed from production where the green cover is sufficient to maintain reasonable cover and made up of grassland, whet, barley oats or triticale. Where grass species are the main cover crop, some stunting and discoloration may occur. Do not apply Savvy on seedling grasses. On green covers,
Savvy should be applied to seedling cereals from the three-leaf stage.
Savvy must only be applied from 1 February, provided the crop has at least two leaves (wheat, oats and triticale) or three leaves (barley), until before the flag leaf sheath extending stage.
Apply Savvy at 30 g/ha when used alone or in tank-mix with other herbicides
In case of crop failure within 3 months from the application of Savvy, sow only wheat
Only cereals, oilseed rape, field beans or grass may be sown in the same calendar year to succeed a cereal crop treated with Savvy.
Crop Safety and timing
Savvy should be applied actively growing linseed (all varieties) from the growth stage “first pair of true leaves unfolded”, up to 30 cm high or before flower buds visible, whichever comes first. Most annual weeds are best controlled by the earliest application possible. When applying Savvy, care should be taken not to overlap spray swaths.
Apply Savvy at 30 g/ha.
Only cereals should be planted within 16 months of applying Savvy to linseed crop
GREEN COVER ON LAND TEMPORARILY REMOVED FROM PRODUCTION
Savvy may be applied to areas temporarily removed from production where the green cover is made up predominantly (i.e. sufficient to maintain reasonable cover) of grassland, wheat barley oats or triticale. Where established grass species are the main cover crop, some discoloration and stunting may occur. Savvy is selective to seedling cereals from the three-leaf stage (GS 13) but should not be used on seedling grasses
Dose and timing
Apply Savvy at 30 g/ha in 200 litres of water/ha before 1 August in year of application. Only one application of a sulfonylurea-containing product must be made per calendar year to green cover on land temporarily removed from production.
Sow only cereals within 16 months of applying Savvy on green cover on land temporarily removed from production e.g. set-aside
Savvy effectively controls broad-leaved docks, with best control achieved from application three weeks before or after cutting. Many other broad-leaved plants occurring in the “set-aside' area will also be controlled or partially controlled, hence it may not be suitable for use where wild flower borders or other forms of conservation headland are to be developed. Before using on land taken out of production as part of a grant-aided scheme, ensure compliance with the management rules of that scheme
