A non-segregating blend of water-soluble granules containing 29 g/kg metsulfuron methyl and 429 g/kg thifensulfuron methyl for spring control of certain broad-leaved weeds in wheat and barley.

Weed control 

PRESITE MAX SX contains two highly active herbicidal ingredients with activity against a wide range of broad-leaved weeds. Metsulfuron-methyl and thifensulfuron-methyl are sulfonylurea herbicides. PRESITE MAX 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 plants 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. 

Resistance
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 with a weed species can be avoided or delayed by alternating (or tank mixing) with suitable products having a different mode of action. For control of Corn Marigold or Chickweed this product must always be applied with an alternative mode of action product at recommended rates.

Crops
PRESITE MAX SX can be used on all varieties of wheat (except Durum wheat) and barley between the growth stages given below.

Dose
Apply PRESITE MAX SX at 140 grams/hectare.

Timing 

PRESITE MAX SX must only be applied in the spring after 1 February from the three-leaf stage up to and including the flag-leaf fully emerged stage of crop growth.

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 MAX SX. In case of crop failure for any reason, sow only winter wheat within three months of application of PRESITE MAX SX. Before sowing, soil should be ploughed and cultivated to a depth of at least 15-cm.

Volume and application
BEFORE USING PRESITE MAX 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.

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

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