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.

GENERAL INFORMATION

CLAYTON MIZEN is both a contact and residual herbicide. It can be used to control weeds in named varieties pre-emergence and, in certain varieties, post-emergence. A list of varieties which may be treated is summarised below. For the latest information, please consult Clayton
Plant Protection (UK) Ltd.
CLAYTON MIZEN should not be used if a previously applied residual herbicide still remains in the soil. This is especially significant on organic soils.

CROP SPECIFIC INFORMATION
Traditional Method
Overall application (not incorporated) pre-emergence to recommended earlies varieties and pre- or post-emergence to recommended maincrop varieties. Persistence and residual activity and weed control may be less than the listed susceptibilities in maincrops grown on all soil types and earlies grown on all soil types except very light and light soils.

Water Volumes
Traditional method : Use a minimum of 200 litres of water per hectare using a Medium Quality spray (as defined by BCPC). Where the soil is cloddy, it is advisable to increase the volume of water. For post-emergence application use a minimum of 130 litres of water per hectare using a Fine – Medium Quality spray (as defined by BCPC).

Application
Apply pre- or post-emergence to the soil surface. Even coverage of both sides of the ridge is important. Care should be taken in particular with post-emergence applications where the crop is sheltering the weeds; it is essential that the spray penetrates the canopy. Do not apply CLAYTON MIZEN in windy conditions.
Filters should be at least size 80 mesh. Filters finer than 80 mesh should not be used.
Specific timings and application methods
Incorporation of CLAYTON MIZEN into the soil
On soils containing greater than 10% organic matter and on mineral soils under dry conditions, CLAYTON MIZEN should be incorporated at a rate of 0.75 kg/ha into the top 10-15 cm of soil during the final cultivation. This gives increased activity and is especially advantageous for those varieties which cannot be treated post-emergence. This method is particularly useful to increase activity on soils with more than 10% organic matter.
Pre-planting: On soils containing greater than 10% organic matter and on mineral soils in dry conditions, apply 0.75 kg/ha of CLAYTON MIZEN, incorporating into the top 10-15 cm of soil during the final cultivation. Suitable cultivators are rotary harrows, rotary cultivators or spring tine harrows.
A suitable granular nematicide may be incorporated into the soil at the same time, in accordance with the manufacturer’s recommendations. After planting, ridging up should occur as soon as possible. It is important that ridges do not incorporate untreated soil which would allow weeds to establish. A final ridging up may be made, before the crop meets across the rows.
For recommended maincrop potatoes grown in two-row beds only, a follow-up postemergence treatment of up to 0.5 kg/ha of CLAYTON MIZEN may be applied. This will give useful control of late germinating weeds in the furrows.
Post-planting: Place the tubers in shallow ridges and apply 0.75 kg/ha of CLAYTON MIZEN.
Before the crop emerges, incorporate by cultivating shallowly while at the same time ridging up. The cultivator should be fitted with suitable ridging bodies. In the case of second early varieties this application may only be made on soils containing more than 10% organic matter.
A further application of up to 0.5 kg/ha of CLAYTON MIZEN will be needed to control later germinating weeds. The second application may also be applied post-emergence before the leading shoots of the potatoes are 15 cm long.
Post-emergence applications :
This method is for use on recommended maincrop varieties only. The method is only recommended until the weeds reach the cotyledon stage. If weeds are beyond this stage control may be reduced.

Rate of Use: On recommended varieties only, make 1 application at 0.35-0.5 kg/ha.

Timing: Application should be carried out at or before early cotyledon stage of the weeds until the most advanced shoots of the potatoes are 15 cm long.
