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.

ALERT is a contact and stomach acting insecticide with residual foliar activity.

Damage may result unless all recommendations are carefully carried out.

DO NOT use less than the minimum volume of water specified.

Reduced volume spraying must not be used on wheat and barley after 31 March in the year of harvest.

This product must not be applied to a cereal crop if any product containing pyrethroid insecticide or dimethoate has been applied to that crop after the start of ear emergence (GS51).

Do not apply this product in tank mixture with a triazole-containing fungicide when bees are likely to be actively foraging in the crop.

It is recommended that as a matter of good practice, spraying in oilseed rape should be carried out in the late evening or early morning or in dull weather if at all possible and local beekeepers should be advised of the intention to spray and the chemical being used.

CONSULT PROCESSORS BEFORE USING ON CROPS FOR PROCESSING.

 

Pests: Cabbage Stem Flea Beetle and Rape Winter Stem Weevil.(Reduction of spread of Beet Western Yellows Virus).

Rate of application: 100 ml/ha

Critical Comments:

TIMING: ALERT should be applied when adult cabbage stem flea beetle feeding damage is first seen on young rape plants. A second application should be made when larval damage is seen in the leaf petioles (normally one month later). In situations where no adult feeding damage is seen, the first application should be made when larval damage is first seen in the leaf petioles, followed by a second application one month later.

NOTE: The use of ALERT for the control of cabbage stem flea beetle will also control the adults and young larvae of rape winter stem weevil if these are present in the crop at the time of application. Applications of ALERT at these timings will also reduce the spread of beet western yellows virus.

 

Pests: Cabbage Seed Weevil and Brassica Pod Midge.

Rate of application: 200 ml/ha

Critical Comments:

TIMING: ALERT may be applied at any time during the flowering period when seed weevil numbers reach the threshold for spraying†. Best results are normally achieved when application coincides with the onset of peak adult activity. This often occurs between the 20 pod set stage and the end of flowering on the main raceme, i.e. 75% petal fall across the entire crop.

 

A total of:

600 ml/ha/crop may be applied to winter oilseed rape

400 ml/ha/crop may be applied to spring oilseed rape with a maximum of

200 ml/ha/crop to be applied after the yellow bud stage in both winter and spring oilseed rape.

Pests: Pollen beetle

Rate of application: 100 ml/ha

Critical Comments:

TIMING: Application should be made at the green to yellow bud stage, as soon as pest numbers reach the threshold† for spraying. A second application may be required 3-7 days later (the exact timing dependent on the speed of pest re-infestation and when the threshold is reached) within the green to yellow bud stage of the crop.

 

Pests: Pollen Beetle and Cabbage Seed Weevil (mixed populations)

Rate of application: 200 ml/ha

TIMING: Application should be made at yellow bud, as soon as pest numbers reach the threshold for spraying.

NOTE: The use of ALERT for the control of pollen beetle and cabbage seed weevil will also give some reduction in the numbers of adults of cabbage stem weevil if these are present in the crop at the time of application.

 

Pests: Cabbage Seed Weevil

Rate of application: 200 ml/ha

TIMING Apply when pest numbers reach the threshold† for spraying, normally from the yellow bud stage of the crop. Application at yellow bud will also control pollen beetle (see separate section on pollen beetle). A further application may be necessary if continuing pest pressure causes the seed weevil threshold† to be reached during flowering on the main raceme, i.e. 75% petal fall across the entire crop.

 

 A total of 400 ml product/ha/crop may be applied to winter and spring wheat and barley up to and including 31 March in the year of harvest, with a maximum of 150 ml product/ha/ crop applied between 1 January and 31 March in the year of harvest, with a latest time of application of before early dough stage.

 

Pests: Cereal Aphids - autumn/winter (reduction of spread of barley yellow dwarf virus and control of yellow cereal fly)

Rate of application: 150ml/ha

Critical Comments:

TIMING High risk situations e.g. crops drilled before the 3rd week of September, crops following grass or grassy stubbles, or crops in areas with a history of BYDV. The first application should be made when aphids are first seen in the crop (or by midOctober). A second application will be necessary at the end of aphid migration, which is normally at the end of October or beginning of November. Where conditions continue to favour prolonged aphid activity, e.g. mild winters, and where two applications of another insecticide have already been made in the autumn, one application of ALERT can be made in December to March.

Other situations Apply in late October or early November to crops which have emerged by mid-October if aphids are found, or on ADAS warnings.

NOTE: ALERT applied in the autumn for aphid control will also give some control of yellow cereal fly if present in the crop.

 

Pests: Cereal Aphids - summer

Reduced volume spraying must not be used for cereal aphid control in wheat and barley after 31 March in the year of harvest.

Rate of application: 150ml/ha in 200 litres of water per hectare. A single application may be made from 1 April to 31 August in any one summer.

TIMING Apply between the onset of flowering and the milky ripe stage (GS 61 to 73) when 66% or more heads are infested (equivalent to five aphids per ear) and aphid numbers are increasing. (Details of thresholds are available from ADAS or your specialist adviser). This product must not be applied to a cereal crop if any product containing pyrethroid insecticide or dimethoate has been applied to that crop after the start of ear emergence (GS 51).

 

Maximum number of applications: 4

Pests: Flea Beetle

Rate of application: 75 ml/ha

Critical Comments:

TIMING Apply as soon as pest attack is observed on seedling plants. Repeat if necessary.

 

Pests: Caterpillars

Rate of application: 100 ml/ha

Critical Comments:

TIMING Apply when damage is first seen or as a preventative spray. Repeat if necessary.

 

Maximum number of applications: 3

Pests: Pea and Bean Weevil

Rate of application: 150 ml/ha.

TIMING Apply when severe damage by adults to growing point is being caused in the early growth stages of the crop. Under high pest pressure a repeat application may be required 2-3 weeks later.

 

Pests: Pea moth

Rate of application: 100 ml/ha.

TIMING Apply according to ADAS/PGRO warnings or as indicated by pheromone traps. For further information consult your specialist advisor. On dry peas repeat 14 days later. If moth activity remains high a third application may be needed.

Rate of application: 150 ml/ha.

TIMING For partial control apply according to current thresholds. Repeat if necessary, up to a maximum of three applications. Consult your specialist advisor for further details

 

Pests: Pea and Bean Weevil
