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. SEAL Z is a contact and stomach-acting pyrethroid insecticide for control of a wide range of pests in wheat, barley, oats, oilseed rape, combine, vining and edible-podded peas, field beans, potatoes, sugar beet, carrots, parsnip, outdoor lettuce, Brussels sprouts, cabbage, cauliflower, broccoli, calabrese and pear crops. To maximise the contact activity, ensure good spray coverage of the target during application.

 

Consult processors before treating crops which are destined for processing.

To reduce the effects on non-target insects and arthropods, do not spray cereals within 5m of the field boundary1.

When using tractor-mounted boom sprayers in arable and vegetable crops, do not apply SEAL Z within 5 m of the field boundary1 to minimise the effects on non-target insects and arthropods.

When treating pears with broadcast air-assisted sprayers, apply in a way which minimises off-target drift. 1 Field boundary buffer distances are measured from the edge of non-cropped land, including the 1-2m adjacent to hedgerows and waterbodies established under the Single Payment Scheme. Whilst cropped land includes buffer strips such as wild flower margins and conservation headlands, these are areas dedicated to be wild life refuges and it is best practice to minimise spray drift into them.

 

RESISTANCE:

Some strains of aphid species have developed resistance to many aphicides. Where aphids resistant to lambda-cyhalothrin occur, SEAL Z will not give satisfactory control and repeated applications will not improve activity. The SEAL Z mode of action is classified by the IRAC mode of action code:’3’. To reduce the risk of the development of resistance to SEAL Z, it is important to ensure that a non-pyrethroid insecticide classified with another mode of action code is incorporated into the pest control programme each year.

 

 

Shake the container before use. Place half the required amount of clean water in the spray tank and commence agitation. Add the required amount of SEAL Z either direct into the tank or via a filling device such as an induction bowl etc. The use of sprayer mounted pressure rinsing equipment is advised. If not available, containers should be manually rinsed three times. Add the remaining water requirement and continue agitation during spraying. Do not allow the spray mixture to stand. Immediately after use wash sprayer and other equipment thoroughly with water and detergent. Dispose of empty rinsed containers according to the DEFRA Code of Practice for the Safe Use of Pesticides on Farms and Holdings. Thoroughly wash all equipment after use.

 

SEAL Z is physically compatible with a range of other products but the efficacy of the mixtures has not been confirmed in trials so use is at the grower’s risk. If using tank mixes, unless directed otherwise the preferred order of addition of products to the tank is: water dispersible granules, wettable powders, suspension concentrates (flowables), emulsifiable concentrates, solution concentrates. Each product must be added to a half-full sprayer and be fully dispersed before the addition of the next product. Tank mixes must only be applied within the label recommendations of every product in the mix. Contact AgchemAccess Ltd. for compatibility information on specific tank mixes. Manufacturer’s instructions must be followed for each tank-mix component.

 

Apply SEAL Z in 200-300 litres of water per hectare to cereals, oilseed rape and field beans. Potatoes require at least 400 L/ha and horticultural brassica crops require 300-600 L/ha plus a non-organo-silicone non-ionic wetter at the manufacturers recommended rate. Sugar beet requires 200-1000 L/ha according to the target while lettuce and carrots should be treated with 200 – 1000 l/ha. Peas need to be treated in 200 – 600 L/ha while pears require 200 – 2000 L/ha. See crop specific information for details of which target pests require which water volume.

 

Apply as a MEDIUM spray (as defined by BCPC).

 

1.1 Aphid vectors of barley yellow dwarf virus:

Apply a routine spray of 50 ml/ha SEAL Z in 200 L/ha during late October to cereals sown in September in areas where BYDV is known to be present. If aphids are seen to be present in the crop before this date, spray immediately and note that further treatments may be required particularly in mild winters. In later sown cereals apply 50 ml/ha in 200 L/ha when a BYDV risk is present. Application is worthwhile up to GS32 of the cereal crop to reduce the risk of BYDV. Routine sprays are advised when the cereal crop follows a weedy stubble or a grass leys due to the risk of direct aphid transfer to the crop.

1.2 Grain aphid or rose grain aphid on the ear:

Apply 50 ml/ha SEAL Z in 200-300 L/ha water to achieve thorough crop penetration of the spray. Optimum timing is after ear emergence (GS59) but applications can be made up to late milk stage (GS77) on wheat and barley and up to GS71 on oats. HGCA threshold for treatment is when aphids are present on two-thirds of tillers. Where aphid numbers are lower than this, check for natural enemies of aphids and spray if none are found.

Apply 50 ml/ha SEAL Z in 200 L/ha at egg hatch which usually starts in late January, depending on the season. Crops which have emerged early are most susceptible but an application of SEAL Z against BYDV vectors will also give some control of this pest.

Apply 50 ml/ha SEAL Z in 200 L/ha water if threshold numbers of adult midge are seen when the crop is at a susceptible stage, i.e. ear emergence to start of flowering (GS 51-59). Note that SEAL Z is only effective against the flying adults and will not reduce the damage caused by larvae hatching from eggs already laid in the ear. Before treatment, check the varietal susceptibility of your wheat since some varieties carry a resistance gene.

Apply 50 ml/ha SEAL Z in 200 L/ha water. Regular inspections of the crop from the 1 leaf stage (GS11) will reveal when the first eggs are laid and treatment must be applied before the majority of the eggs hatch.

 

Apply 75 ml/ha SEAL Z in 200 L/ha at the first sign of pest attack and repeat 10-14 days later if necessary.

Apply 50 ml/ha SEAL Z in 200 L/ha water with non-organo-silicone non-ionic wetter at the manufacturers rec. rate when feeding damage is first seen in the autumn or when economic thresholds of larvae are present. If further active larvae are found, a second application may be required and, in high risk areas, a routine application may be justified late October – early November.

Apply 75 ml/ha SEAL Z in 200 L/ha water with non-organo-silicone non-ionic wetter at the manufacturers rec. rate when the aphids are seen in the crop. After 3-4 weeks apply a second spray if aphids continue to appear in the crop. Any delay in treatment can result in poorer control of the virus. Note that this treatment can also give control of cabbage stem flea beetle infestations since the timings often coincide in the autumn.

Apply 75 ml/ha SEAL Z in 200 – 300 L/ha water to achieve good canopy penetration at the green/yellow bud stage of the oilseed rape in accordance with either specialist advice or when the threshold is reached (15 beetles per plant in well-established crops, 5 beetles per plant in backward or pigeon-damaged crops and 3 beetles per plant in spring oilseed rape).

Apply 75 ml/ha SEAL Z in 200 – 300 L/ha water to achieve good canopy penetration during crop flowering provided that seed weevil numbers have reached the threshold (1 seed weevil per 5 plants of spring or winter oilseed rape. Note that this also takes into account the pod midge risk since these lay eggs in the feeding holes of the seed weevil). The best timing of the spray is from 20% pod set up to 75% petal fall. Note that spraying must stop at the end of flowering in winter rape and six weeks before harvest is spring rape. A repeat application may be required where pest attack is prolonged. DO NOT spray in the heat of the day when bees are most active in the crop.

 

3.1 Pea & bean weevil:

Apply 75 ml/ha SEAL Z in 200 – 300 L/ha water when feeding damage (notching of the leaves) is first seen in the crop if there is a risk to the growing points of the crop. Where the number of weevils is high, a second application can improve control if applied 2 – 3 weeks after the first treatment.

 

4.1 Pea & bean weevil:

Apply 75 ml/ha SEAL Z in 200 L/ha water when feeding damage (notching of the leaves) is first seen in the crop if there is a risk to the growing points of the crop. Where the number of weevils is high, a second application can improve control if applied 2 – 3 weeks after the first treatment.

4.2 Pea moth:

Apply 50 ml/ha SEAL Z in 300 - 600 L/ha water to achieve good canopy penetration. The timing of the spray is when the crop is in full flower or as advised by the results of pheromone traps (10 moths in a pair of traps on consecutive occasions) or official advice. Combining peas may require a second treatment 10 – 14 days after the first spray but vining peas should only receive a single spray on the advised date.

Apply 50 ml/ha SEAL Z in 300 - 600 L/ha water to achieve good canopy penetration. The timing of the spray is when the threshold is reached (20 – 30% of shoots infested between first flower and pod set on 4th truss in combining peas). Inspect the crop carefully during flowering and repeat the application if necessary. Where aphid infestations are well established and sheltered within the crop canopy, use a tank-mixture with 140 g/ha 50% w/w pirimicarb (e.g. MAPP 14523 or 10515). If aphids are the only pest attacking the crop and are hidden within the crop canopy, applying 280 g/ha of the pirimicarb product alone will be a better treatment choice.

Apply 75 ml/ha SEAL Z in 300 – 600 L/ha water to achieve good canopy penetration within 3 – 5 days of the finding of the first adult midges in the crop. Where necessary, sprays can be repeated 7-10 days later if midge activity continues and the crop is at a susceptible stage.

 

5.1 Aphids:

Apply 75 ml/ha SEAL Z in at least 400 L/ha water to achieve good crop canopy penetration. Treat seed and ware crops to minimise the spread of potato viruses when aphids are first seen in the crop and use in mixture with 50% w/w pirimicarb product (e.g. MAPP 14523 or 10515) to improve activity provided that aphids resistant to pirimicarb are not present. An application of SEAL Z can also give some control of cutworms since the timing coincides with that for aphids.

 

6.1 Flea beetle:

Apply 75 ml/ha SEAL Z in 200 l/ha water as soon as adult feeding damage is seen in the crop and repeat if necessary.

Apply 75 ml/ha SEAL Z in 200 L/ha water at egg hatch and repeat as necessary.

6.3 Cutworm:

Apply 75 ml/ha SEAL Z in 400 – 1000 L/ha water at egg hatch and repeat 10 – 14 days later, noting the eight week harvest interval.

Apply 50 ml/ha SEAL Z in 300 – 600 L/ha water with a non-organo-silicone non-ionic wetter at the manufacturers rec. rate to achieve good crop penetration. Brussels sprouts can benefit from application via a drop leg sprayer. Treat at the first sign of attack and repeat as necessary.

7.2 Whitefly:

Apply 100 ml/ha SEAL Z in 300 – 600 L/ha water with a non-organo-silicone non-ionic wetter at the manufacturers rec. rate to achieve good crop penetration. Brussels sprouts can benefit from application via a drop leg sprayer. Treat at the first sign of attack and repeat as necessary.

 

8.1 Pear sucker:

Apply 90 ml/ha SEAL Z in 200 – 2000 L/ha water to achieve good crop penetration when the first sucker eggs are being laid in Spring (late Feb – early March). In the absence of effective predators, sucker numbers can build up in summer and where this occurs, make another application of the same dose and repeat 2-3 weeks later if necessary. Some pear sucker populations have developed resistance to pyrethroid insecticides and where these occur, SEAL Z may not give satisfactory control. Use ingredients with a different mode of action code when retreating.

 

9.1 Cutworm:

Apply 75 ml/ha SEAL Z in 400 – 1000 L/ha water to achieve thorough crop canopy penetration at egg hatch or when advised and repeat 10 – 14 days later.

 

10.1 Cutworm:

Apply 75 ml/ha SEAL Z in 400 – 1000 L/ha water to achieve thorough crop canopy penetration at egg hatch or when advised and repeat 10 – 14 days later.

Apply 150 ml/ha SEAL Z in 300 – 600 L/ha water as a medium or fine spray to achieve good cover of the foliage. SEAL Z is only effective against adult flies and will not control larvae in the carrot root or in the soil. HRI and specialist advisers forecast when 10% egg laying is likely to occur and the first application should be one week before this date. Up to two repeat applications at 12 – 14 day intervals should be made as a regular programme to reduce the incidence of egg laying as far as possible and these are best times at 4-6pm on warm still evenings to maximise the effects on the adults. Note that the maximum permitted dose is 450 ml/ha/crop.
