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.

Restrictions
 PRESITE SX must not be applied to any crop suffering from stress as a result of drought, water-logging, low temperature, pest or disease attack, nutrient deficiency, soil compaction or other factors reducing plant growth.
Do not use PRESITE SX on crops undersown with grasses, clover or other legumes or any other broad-leaved crop.
Because some non-target crops are highly sensitive to PRESITE SX, 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 - see separate section.
Crop failure: In the event of crop failure for any reason, sow only winter wheat within three months of application of PRESITE SX. Prior to sowing, soil should be ploughed and cultivated to a depth of at least 15-cm.
Do not apply within 7 days of rolling the crop.
Contract agents should be consulted before using on crops grown for seed.
Refer to ‘Compatibility’ for details on use of PRESITE SX with other ‘ALS inhibiting’ herbicides.

Weed Control
PRESITE 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. PRESITE 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.

Soil
PRESITE SX can be used on all soil types. Weed control may be reduced when conditions are very dry.

Volume and application
BEFORE USING PRESITE 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.

Mixing
Quarter fill the spray tank with clean water, start the agitation and add the required quantity of PRESITE SX directly to the tank without prior creaming. Continue agitation while topping up the tank and while spraying.

Crops
PRESITE 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.

Dose
Apply PRESITE SX at 75 grams/hectare.

Timing
Wheat and barley: PRESITE SX must only be applied from 1 February, from the three leaf stage up to before flag-leaf sheath extending stage (GS39) Winter Oats: PRESITE SX must only be applied from 1 February, from the three leaf stage up to before second node detectable (GS32).

Following crops
Only cereals, oilseed rape, field beans or grass may be sown in the same calendar year as harvest of a cereal crop treated with PRESITE SX. In case of crop failure for any reason, sow only winter wheat within three months of application of PRESITE SX. Before sowing, soil should be ploughed and cultivated to a depth of at least 15-cm.
