A water-dispersible granule containing 50% w/w triflusulfuron-methyl, a sulfonylurea. For use only as an agricultural herbicide for the control of certain broad-leaved weeds and volunteer rape in sugar beet.fodder beet and mangolds.

WEED CONTROL

Susceptible plants cease growth almost immediately after application and symptoms can be seen about 5 to 10 days after application. Best results are achieved when DEBUT plus adjuvant or approved tank-mix partner are applied in a programme of up to four sequential sprays.

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 DEBUT plus appropriate tank-mix partner.

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.

CROP
DEBUT can be used on all varieties of sugar beet, fodder beet and mangolds at the growth stages given below.

TIMING
The first application should be made in the spring when the first weeds have emerged.
Subsequent applications should be made every 5 - 14 days when new flushes of weeds are at or just past the cotyledon stage.
Do not apply DEBUT after the crop has met between the rows. Do not apply DEBUT more than four times to any sugar beet, fodder beet or mangold crop.
DEBUT mixtures can be applied from the early cotyledon stage of sugar beet, fodder beet or mangolds as part of a planned programme following pre-emergence application of VENZAR FLOWABLE or chloridazon-based products at commercially recommended doses.

SOIL
DEBUT can be used on all soil types. Weed control may be reduced when soil conditions are very dry.

WEATHER
Avoid high light intensity (full sunlight) and high temperatures (above 21°C) on the day of spraying. Avoid periods of substantial day to night temperature changes or when frost is expected.

DOSE
DEBUT should be applied at 30 g/ha in conjunction with a recommended adjuvant or suitable herbicide tank-mix partner(s).

VOLUME AND APPLICATION
BEFORE USING DEBUT, SPRAYING EQUIPMENT MUST BE CLEAN AND FREE FROM
CONTAMINATION WITH OTHER PESTICIDES.

OVERALL APPLICATION
DEBUT should be applied overall in 80 - 150 litres of water per hectare, using suitable equipment to give a FINE spray, as defined by BCPC. Good, even spray cover of the weeds is essential for best results.
When applying DEBUT, care should be taken not to overlap spray swaths.

BAND APPLICATION
Similar doses, water volumes and spray quality should be used as in overall application, but the area covered will be dependent upon the row spacing and band width. Careful calibration is essential to achieve best results.

MIXING
DEBUT mixes easily with water, but the following mixing procedure should be followed:
Quarter fill the spray tank with water and start the agitation. Add the required quantity of DEBUT directly to the tank. Continue agitation while topping up the tank and while spraying.
Use the tank the same day as mixing.

COMPATIBILITY
In any tank-mix add DEBUT to the tank first and ensure it is fully dispersed before adding the partner product(s).
To widen the spectrum of activity, DEBUT should be tank-mixed with an adjuvant or with other herbicides (see WEED SUSCEPTIBILITY table). Products should only be tank-mixed if each product can be applied within the manufacturer's label recommendation for its use.
DEBUT can be tank-mixed with approved formulations of products containing 25 g/L
desmedipham, 75 g/L phenmedipham plus 151 g/L ethofumesate and/or VENZAR®
FLOWABLE or approved formulations of metamitron to control a broader range of weeds.
To avoid antagonism, metamitron (70%) should not be added in excess of 0.5 kg/ha.
When DEBUT tank-mixes are used in sequence with graminicides, the minimum time interval should be observed between applications in accordance with the manufacturer's recommendations.
