Harmony Max SX
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 broadleaved weeds in wheat and barley.
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.
HARMONY MAX SX 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 HARMONY MAX SX on cereal crops undersown with grasses, clover or other legumes or any other broad-leaved crop.
Do not apply HARMONY MAX SX to any cereal crop in sequence or in tank-mixture with a product containing any other sulfonylurea herbicides except with:
Flupyrsulfuron-methyl in combination with carfentrazone-ethyl
Amidosulfuron (Only cereals may be sown as a following crop)
Due to the high level of activity of the herbicide, special care must be taken to avoid damage by drift onto broadleaved plants outside the target area, or onto ponds, waterways or ditches. Thorough cleansing of equipment is also very important - see below.
Contract agents should be consulted before using on crops grown for seed.
HARMONY MAX SX should not be applied within 7 days of rolling the crop.
Do not apply HARMONY MAX SX more than once to any cereal crop.
HARMONY 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. HARMONY 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.
The susceptibility rating of weeds in the following table refer to good spray cover and good growing conditions.
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.
HARMONY MAX SX can be used on all varieties of wheat (except Durum wheat) and barley between the growth stages given below.
Apply HARMONY MAX SX at 140 grams/hectare.
HARMONY 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.
Only cereals, oilseed rape, field beans or grass may be sown in the same calendar year as harvest of a cereal crop treated with HARMONY MAX SX. In case of crop failure for any reason, sow only winter wheat within three months of application of HARMONY MAX SX. Before sowing, soil should be ploughed and cultivated to a depth of at least 15-cm.
Volume and application
BEFORE USING HARMONY 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
HARMONY MAX SX 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 HARMONY MAX SX directly to the tank without prior creaming. Continue agitation while topping up the tank and while spraying.
In any tank-mix add HARMONY MAX SX to the tank first and ensure it is fully dispersed before adding the partner product. Do not allow HARMONY MAX SX 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.
