DU PONT - herbicide
02330

A non-segregating blend of water soluble granules containing 40 g/kg metsulfuronmethyl and 400 g/kg thifensulfuron-methyl for spring control of broad-leaved weeds in winter wheat, spring wheat, winter barley, spring barley and winter oats.

DIRECTIONS FOR USE
Restrictions
Do not apply 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 apply to cereal crops undersown with grass, 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.
Do not apply within seven days of rolling the crop.
Do not apply more than once to any cereal crop.
Failure to clean the sprayer thoroughly after use can result in damage to sensitive crops later. Follow washout instructions and only use label-recommended tank mixtures.

Weed Control
HARMONY® M SX is a highly active herbicide that works mainly by foliar action with some root activity. It controls a wide range of broadleaved weeds and is most effective if applied when the weeds are small and actively growing. Good spray cover of the weeds must be obtained and, since larger weeds often become less susceptible, it is important to note the size of each weed 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. It is important to identify the weeds occurring in the crop and refer to the weed table to ensure that the weeds present are those susceptible to HARMONY® M SX. The susceptibility ratings of weeds in the following table refer to good spray cover and good growing conditions.

Weed 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. For the control of Corn Marigold and Chickweed, this product must always be applied in a mixture with an alternate mode of action herbicide at recommended rates. Development of resistance within a weed species can be avoided or delayed by alternating (or tank-mixing) with suitable products having a different mode of action.

Crops
HARMONY® M SX can be used on all varieties of winter wheat (except Durum wheat) , spring wheat, winter barley, spring barley and winter oats between the growth stages given below.

Timing
HARMONY® M SX should be applied in the spring from the three-leaf stage of the crop up to the flag leaf fully emerged stage of crop growth (GS 39).

Dose
Spring barley and spring wheat - apply at 100 g/ha Winter wheat and winter barley - apply at 125 g/ha Winter oats – apply at 125g/ha

Soil and Weather
HARMONY® M SX can be used on all soil types. Weed control may be reduced when conditions are very dry. Rain within four hours of application may reduce the effectiveness of the product.

Following Crops
Only cereals, oilseed rape, field beans or oilseed rape may be sown in the same calendar year as harvest of a cereal crop treated with HARMONY® M SX. In the event of a crop failure for any reason, sow only a cereal crop within three months of application of HARMONY® M SX. Prior to sowing, soil should be ploughed and cultivated to a depth of at least 15-cm.

Volume and Application
BEFORE USING HARMONY® M 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 equipment to give 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. When applying HARMONY® M SX, 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 HARMONY® M SX directly to the tank without prior creaming. Continue agitation while topping up the tank and while spraying.

Compatibility
In any tank-mix add HARMONY® M SX to the tank first and ensure it is fully dispersed before adding the partner product. Do not allow HARMONY® M 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.
