A pre- and post-emergence herbicide for the control of annual broad-leaved weeds and annual meadow grass in sugar beet, fodder beet, red beet and mangels. Suspension Concentrate containing 700 g/l (58 % w/w) metamitron.

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.

RESTRICTIONS
DEFIANT can be safely applied to all varieties of sugarbeet, fodder beet, red beet and mangels, when applied as recommended, to stress free crops. When crops are under stress such as very wet conditions, intense sunlight, sudden temperature fluctuations, disease and insect attack, nutrient deficiency, wind damage or stress or damage from previous pesticide application, then tolerance may be reduced.

WEED CONTROL
DEFIANT will give control of a wide range of weeds when actively growing at the cotyledon stage. The following table summarises weed control for a low dose sequence of post-emergence applications of DEFIANT 1.7 litres/ha + Adjuvant oil 1.7 litres/ha, timed to successive emergence of weeds at the early cotyledon stage. Weed control can be enhanced by tank mixing (see section on tank mixing for further information).

CROP SPECIFIC INFORMATION
DEFIANT is a suspension concentrate for the control of broad-leaved weeds through contact and residual activity. It can be used on sugar beet, fodder beet, red
beet and mangels, as a pre- or post-emergence treatment and may also be used in certain tank mixes (see section ‘COMPATIBILITY’). Apply DEFIANT in a spray programme. One pre-emergence application can be made, which may be incorporated. Follow the pre-emergence application with a post-emergence programme. Please refer to the pre- and post-emergence application sections for specific information. Application should be made as a repeat overall low dose programme. For residual activity and efficacy to be optimum, a full programme of sprays is recommended. Cotyledon tip scorch may occasionally result because beet plants are very sensitive to herbicide treatment if under stress.

SOIL PREPARATION
Prepare a firm fine seedbed for best results. Drill to normal depth to ensure seed is well covered. Do not roll or harrow treated soil as this may lead to germination of another flush of weed from disturbed soil. Best results will be achieved if the soil is moist. Weed control may be reduced under very dry conditions.

FOLLOWING CROPS
If a treated crop fails for any reason, only sugar beet, fodder beet and mangels should be sown within four months of the last application of DEFIANT. After harvesting crops treated with DEFIANT, the land should be mould-board ploughed to a depth of 15 cm before planting any crop. Winter cereals may then be sown, providing at least 16 weeks have elapsed from the last application of DEFIANT. In the following spring, any spring crop can be drilled or planted.

MIXING AND SPRAYING
On emptying the container, RINSE CONTAINER THOROUGHLY by using an integrated pressure rinsing device or manually rinsing three times. Add washings to
sprayer at time of filling and dispose of container safely.Half fill the sprayer tank with clean water. Begin agitation and add the required quantity of DEFIANT
to the sprayer tank. Then add the adjuvant oil and/or other herbicide. Fill the spray tank whilst agitating and maintain agitation until spraying is completed. When
spraying take care to avoid drift onto neighbouring crops, buildings or non-target plants. After spraying drain the tank completely and thoroughly clean the inside of the tank. Flush the tank, hoses and boom with clean water for at least 5 minutes. Partially fill the tank with clean water and add a cleaning agent if necessary. Complete filling the tank with water, then flush the cleaning solution through the hoses, boom and nozzles. Repeat this procedure with clean water.
Remove the nozzles and screens and clean separately in a bucket containing water (and cleaning agent).
