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

SHOTPUT® 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. See below for list of varieties which may be treated.

RESTRICTIONS

Avoid drift as SHOTPUT® may damage sensitive crops especially horticultural crops such as brassicas and lettuce.
Care should be taken to avoid spray overlap, as crop damage may occur which may not be outgrown.
Do not apply SHOTPUT® to crops suffering from disease, stress or nutrient deficiencies or that are cold, waterlogged or grown in acidic conditions. SHOTPUT® should not be used if a previously applied residual herbicide still remains in the soil. This is especially significant on organic soils.

Soil types and conditions

Do not use SHOTPUT® on sands. Do not use SHOTPUT® pre-emergence on Maris Piper in very light soils and do not treat this variety post-emergence.

Tubers should be planted in a moist, clod-free bed with a good tilth with well-rounded ridges. After planting, no further improvements should be required to the soil tilth; further cultivations will increase weed germination and reduce the effectiveness of SHOTPUT®. However, if there are still clods in the soil, it is advisable to increase the water volume when using the traditional method of application of the herbicide. The soil should be moist when spraying. Dry conditions may reduce the effectiveness of SHOTPUT®.

Weather

Yellowing of foliage may occur as a result of treatment, which is more frequent if spraying is carried out less than 3 days after cool cloudy weather and particularly if a sudden change to hot sunny conditions occurs at the time of spraying. The crop should outgrow this yellowing. In conditions of high sunlight intensity and high daytime temperatures, spraying should be carried out in the evening.

On gravelly or stony soils damage may occur particularly if heavy rain falls soon after application.

Following crops

Before drilling or planting the next crop, the soil must be mould-board ploughed to a depth of at least 15 cms. It is recommended that ploughing takes place as soon as possible after lifting and definitely before the end of December.

The following intervals must be observed between application of SHOTPUT® and drilling or planting the following crops:

Cereals, rye-grass, winter beans: 16 weeks

All crop except lettuce and radish: the following spring

Lettuce and radish: these crops should not be grown in the year after SHOTPUT® treatment.

Specific weed situations

Early Germinating Weeds

For best control, apply SHOTPUT® between the cotyledon to one true leaf stage.

Late Germinating Weeds, including Black Bindweed

An extra 0.5 kg/ha may be applied to all the maincrop and second early varieties which SHOTPUT® is recommended for use on post-emergence. The herbicide must be applied before the most advanced shoots of the crop reach 15 cm in length.
Black bindweed is best controlled at the cotyledon to 2 true leaf stage. It is less sensitive to pre-emergence treatments.

Wild-oat

SHOTPUT® will give some control of germinating wild-oats up to the two-leaf stage. It will not control seedlings which are germinating from considerable depth. However, if SHOTPUT® has been used pre-emergence, then a suitable approved graminicide may be used post-emergence to control the wild-oats.

Common Couch

SHOTPUT® will suppress Couch grass when applied post-emergence up to the two-leaf stage. If the couch infestation is severe, the use of a suitable approved graminicide, either pre-planting or pre-emergence is recommended. SHOTPUT® may then be used post-emergence on the recommended second early and maincrop varieties. Alternatively, if SHOTPUT® is used pre-emergence, then a suitable approved graminicide may be used post-emergence to control the Couch grass.

Other Perennial Grasses

If the potato crop follows grass, then either a suitable herbicide and/or cultivations should be used to kill the sward in the autumn. If any grass survives, it may be controlled post-planting using diquat. Following weeds can then be controlled using SHOTPUT® post-emergence on recommended second early and maincrop varieties.

CROP SPECIFIC INFORMATION

Traditional Method

Overall application (not incorporated) pre- or post emergence to recommended varieties

Potato & Soil Type* Rate

Earlies (first and second):
Very light and light soils: 0.75 kg/ha
Medium and Heavy soils: 1.0 kg/ha

Very light and light soils: 1.0 kg/ha
Medium, heavy, peaty and organic: 1.5 kg/ha

Low Dose Method #

Listed maincrop varieties:

All soils: 0.35 or 0.5 kg/ha #

# See Specific Timings and Application Methods below.
* Soil Classification ADAS 85 system.

Do not use SHOTPUT® on potatoes grown in sand soils.

Water volumes

Traditional method:

Use not less than 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.

Low Dose Method:

Use 80-100 litres of water per hectare and a Fine 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 SHOTPUT® 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 SHOTPUT® into the Soil

On soils containing greater than 10% organic matter and on mineral soils under dry conditions, SHOTPUT® should be incorporated at a rate of 1.5 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 1.5 kg/ha of SHOTPUT®, 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 post-emergence treatment of 0.5 kg/ha of SHOTPUT® 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 1.0 kg/ha of SHOTPUT®. 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 0.5 kg/ha of SHOTPUT® will be needed to control later germinating weeds. This may be applied alone or in tank-mix with diquat pre-emergence. The second application may also be applied post-emergence before the leading shoots of the potatoes are 15 cms long. Post-emergence application to second earlies may only be made to variety Marfona.

Post-emergence Low Dose Applications

This method is for use on recommended maincrop varieties only. The advantage of this method is that retention of spray deposit on the leaf surface is improved. To achieve this, smaller nozzle orifices are used and the pressure is increased to give a smaller droplet size. It is also quicker to apply than the traditional method.

The method is only recommended until the weeds reach the cotyledon stage. If weeds are beyond this stage at the first application the traditional application method should be used. It is important to check the crop every few days to see if further weeds have germinated. If any weeds survive an application, a further application should be made seven to ten days later even if no new weeds have emerged.

Rate of Use: On recommended varieties only, make up to 3 applications at 0.35 kg/ha or 2 applications at 0.5 kg/ha.

Timing: Apply the first spray when the weeds are at the early cotyledon stage. Further applications should be carried out on subsequent flushes of weeds at or before early cotyledon stage of the weeds until the most advanced shoots are 15 cm long.

Temporary plastic mulches

Using the traditional method of application, early potatoes may be treated with SHOTPUT® and covered with plastic mulches. Since effective control of weeds by SHOTPUT® is dependent on soil moisture, it is important that crops are well irrigated before the mulch is applied. Application should also be made to well-prepared, clod-free ridges. If using this method on mineral soils with a high organic matter content the residual activity of SHOTPUT® may be reduced. This may result in inadequate weed control.

MIXING AND APPLICATION

Add half the required amount of water to the spray tank and begin agitation. Add the recommended quantity of SHOTPUT®. Rinse the empty container thoroughly and add the rinsate to the spray tank through the filter basket. Add the rest of the water. Maintain agitation throughout the filling travelling and spraying operations. Dilute solutions should be sprayed immediately. After spraying, thoroughly clean the sprayer using a recognised decontaminant.
