A non-segregating blend of water soluble granules containing 40 g/kg metsulfuron-methyl and 400 g/kg thifensulfuron-methyl for spring control of broad-leaved weeds in winter wheat, spring wheat and spring barley.
IMPORTANT: THIS INFORMATION IS APPROVED AS PART OF THIS PRODUCT LABEL. ALL INSTRUCTIONS WITHIN THIS SECTION MUST BE READ CAREFULLY IN ORDER TO OBTAIN SAFE AND SUCCESSFUL USE OF THIS PRODUCT.
DIRECTIONS FOR USE:
TUSKER 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 TUSKER on cereal crops under-sown with grasses, clover or other legumes or any other broad-leaved 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- see below.
TUSKER must not be tank-mixed with certain pesticides (see COMPATIBILITY section).
Contract agents should be consulted before using on crops grown for seed.
TUSKER contains two highly active herbicidal ingredients with activity against a wide range of broad-leaved weeds. Metsulfuron-methyl and thifensulfuron-methyl are Soil sulfonylurea herbicides. TUSKER 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. TUSKER can be used on all soil types.
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.
TUSKER can be used on all varieties of wheat (except Durum wheat) and spring barley between the growth stages given below.
Winter wheat – apply TUSKER at 125 g/ha
Spring wheat – apply TUSKER at 100 g/ha.
Spring barley – apply TUSKER at 100 g/ha
TUSKER 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. Tusker should not be applied within 7 days if rolling the crop. Do not apply TUSKER more than once to any cereal crop.
Only cereals, oilseed rape, field beans or grass may be sown in the same calendar year as harvest of a cereal crop treated with TUSKER.
Volume and application:
BEFORE USING TUSKER, 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:
TUSKER can be used on all soil types. Weed control may be reduced when conditions are very dry.
Quarter fill the spray tank with clean water, start the agitation and add the required quantity of TUSKER directly to the tank without prior creaming. Continue agitation while topping up the tank and while spraying.
In any tank-mix add TUSKER to the tank first and ensure it is fully dispersed before adding the partner product. Do not allow TUSKER to come into contact with undiluted pesticide concentrate. Products should only be tank-mixed if each product can be applied within the label recommendations for its use.
