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.
FINISH SX contains two highly active herbicidal ingredients and has both foliar and root activity against a wide range of broad-leaved weeds. Metsulfuron-methyl and thifensulfuron-methyl are sulfonylurea herbicides. FINISH SX is most effective when applied to small, actively growing weeds. As larger weeds usually become less susceptible, it is important to note the size of each weed species at the time of application.
Susceptible weeds cease growth almost immediately after post-emergence application and symptoms can be seen about two weeks after application. Good spray cover of the weeds must be obtained. Weed control may be reduced when soil conditions are very dry.
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 tank-mixing 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.
The susceptibility ratings of weeds in the following table refer to good spray cover and good growing conditions.
FINISH SX can be used on all soil types. Weed control may be reduced when conditions are very dry.
Volume and application
BEFORE USING FINISH SX, SPRAYING EQUIPMENT MUST BE CLEAN AND FREE FROM CONTAMINATION WITH OTHER PESTICIDES.
Application should be made in 200 litres of water per hectare using suitable ground equipment to give good spray cover of the weeds. In thick crops or dense weeds use higher volumes of water (up to 400 litres of water/ha) to ensure good spray cover of the weeds. Use a conventional field crop sprayer at a pressure of 2 - 3 bars and apply as a MEDIUM spray (as defined by BCPC). Care should be taken not to overlap spray swaths.
Quarter fill the spray tank with clean water, start the agitation and add the required quantity of FINISH SX directly to the tank without prior creaming. Continue agitation while topping up the tank and while spraying.
To widen the spectrum of activity and improve the control of some weeds, FINISH SX may be applied with other herbicides, provided each product can be applied within the label recommendations for its use. Always add FINISH SX to the spray tank first when using in tank-mix.
The following ‘joint application’ with other sulfonylurea and ‘ALS inhibiting’ herbicides may be applied to a crop. Requirements and restrictions on other product labels must be adhered to. ‘Joint application’ is the use of FINISH SX in tank mixture or sequence withone of the products listed below.
FINISH SX can be used on all varieties of winter wheat, spring wheat, winter barley, spring barley and winter oats between the growth stages given below.
Apply FINISH SX at 75 grams/hectare.
Wheat and barley:
FINISH SX must only be applied from 1 February, from the three leaf stage up to before flag-leaf sheath extending stage (GS39)
FINISH SX must only be applied from 1 February, from the three leaf stage up to before second node detectable (GS32)
Only cereals, oilseed rape, field beans or grass may be sown in the same calendar year as harvest of a cereal crop treated with FINISH SX. In case of crop failure for any reason, sow only winter wheat within three months of app lication of FINISH SX. Before sowing, soil should be ploughed and cultivated to a depth of at least 15-cm.
