FORMULATION & ACTIVE INGREDIENT: TERIDOX is an emulsifiable concentrate containing 500 g/l dimethachlor.
TARGETS: For control of a range of annual broad-leaved weeds and loose silky-bent in winter oilseed rape.
RAINFASTNESS: 1 hour
DIRECTIONS FOR USE
IMPORTANT: This information is approved as part of the Product Label. All instructions within this section must be carefully read in order to obtain safe and successful use of this product.
GENERAL INFORMATION
TERIDOX contains the active substance dimethachlor which is part of the chloroacetamide group and is characterised by a broad spectrum of effect against monocot and dicot weeds
in winter oilseed rape. Dimethachlor is mainly taken up via the shoot and hypocotyl of germinating weeds and weed grasses. In the plant, dimethachlor inhibits cell division in weeds which then fail to emerge or die immediately after emergence.

RESISTANCE MANAGEMENT
Strains of some annual grasses, e.g. black-grass, wild-oats and Italian rye-grass, have developed resistance to herbicides which may lead to poor control. A strategy for preventing and managing such resistance should be adopted. Guidelines have been produced by the Weed Resistance Action Group and copies are available from the HGCA, CPA, your distributor, crop advisor or product manufacturer.
CROP SPECIFIC INFORMATION
Crops: TERIDOX can be used on all varieties of winter oilseed rape.
Timing: Use TERIDOX pre-emergence of the crop and weeds.
Rates of use: 2.0 l/ha TERIDOX
Use of adjuvants: No adjuvant is needed with TERIDOX
Important notes: Damage to the crop is possible. A fine, friable, well settled seedbed is important for a good effect and crop safety, as well as even emergence of the winter oilseed rape. The rape seed must be covered with at least 2 cm of fine, friable soil material.
Moist soil conditions accelerate the onset of effect; persistent dry conditions can delay the effect. Application to a completely dry soil is not recommended.
High rainfall in the first weeks after treatment can lead to leaf discolouration, inhibition of growth and, in extreme cases, to a thinning out of the crop. Treatment with TERIDOX should therefore not take place on very porous, poorly sorptive soils (sands).
Extremely high rainfall during the few days after application can lead to a reduced effect, particularly on shallow germinating species.
In spring, newly emerging weeds are not always satisfactorily controlled by TERIDOX.
FOLLOWING CROPS
When TERIDOX is used in accordance with the label directions, there are no following crop restrictions within the context of a normal crop rotation.
Should a crop treated with TERIDOX fail for any reason during the autumn, winter oilseed rape can still be sown in the autumn of the year of application after deep (15 cm) tillage. If the next crop is winter cereals, ploughing to a minimum of 20 cm deep is required.
Following crop failure in the spring for any reason, spring oilseed rape, peas, field beans, maize or potatoes can be grown following minimal tillage of the soil. Following ploughing
spring wheat, spring barley, oats, phacelia, sunflowers, linseed, fodder grasses or sugar beets
can be grown.
MIXING AND SPRAYING
Mixing Procedure
Make sure the sprayer is set to give an even application at the correct volume. Fill the spray tank with half the required volume of water and begin agitation. Add the required amount
of TERIDOX to the spray tank and allow to disperse. Add the rest of the water and continue to agitate the mixture thoroughly. Always agitate during spraying.
Spray Volume
Spray TERIDOX in 200-400 litres of water per hectare.
Application methods
Apply through a conventional field crop sprayer as a MEDIUM quality spray (as defined by the BCPC) using a pressure of 2-3 bars. Ensure the sprayer is correctly calibrated before use.
Avoid left over spray liquid. Only prepare as much spray liquid as is actually needed.
1. Half fill the tank with water
2. Switch on the agitator
3. Pour the product directly into the tank.
4. Carefully rinse out empty containers and add the rinse water to the spray liquid.
5. Fill up the tank with the remaining amount of water.
6. Apply the spray liquid immediately after preparation with the agitator running
Extreme care must be taken to avoid spray drift onto non-crop plants outside of the target area.
When applying TERIDOX, care should be taken to obtain a good, even distribution of the spray liquid.
Avoid overdosing and drift. Overdosing can cause damage to following crops.
After use
When spraying is finished the equipment must be carefully rinsed.
- Dilute any residual spray solution with water in the ratio 1:10 and apply to previously treated areas with the agitator running
- Fill the tank about 10-20% full with water, spraying the inside of the tank with the water jet, preferably using an integral cleaning nozzle. Switch on the agitator for at least 15 minutes. Then, with the agitator running, spray the cleaning liquid through the nozzles
onto the treated areas.
- Roughly clean the sprayer on site with water and a brush. Do not allow remaining cleaning water to enter the sewerage system and bodies of water via the farm drains. Disposal of spray tank washings should be in accordance with local or national legislation.
