Sumi-Alfa 5 EC 1 l

Home use: 3 ml/10 l water.

Suggested technology

Control on or adjacent to flowering vegetation should only be started after the end of the daily flight period of the bees and not earlier than one hour before astronomical sunset. Treatment should be completed by midnight or should be interrupted from midnight until dusk the following day.

Treatments should be carried out based on the forecast, at the time of pest establishment and at the most sensitive phenological stage.

In oilseed rape, if the oilseed rape weevil is not present, a lower dose is recommended. For repeated treatments, and if the pest insect population also contains oilseed rape weevil, the higher dose should be used.

In maize, corn earworm should be sprayed during the period of mass larval infestation. The control of corn earworm imago is aimed at killing the beetles before egg laying, reducing the next year's larval damage and avoiding the chewing of the cob and thus incomplete fertilisation. Control should be timed to the time of mass swarming, preferably before the beetles lay their eggs. The swarming dynamics of beetles can be obtained by using yellow sticky traps, and egg-laying by individual examination of the egg contents of the imago (by lightly pressing the beetles' pots and using a hand-held magnifying glass). If the female flowering has not yet exceeded 50% and at the same time a 1,5 cm recurrence of green buds is already observed in the field, control measures should be taken immediately. As the product is not long-lasting, repeated control(s) may be necessary depending on the vigour of the imago. During the pollen dispersal (male flowering) period of maize, or when the field to be protected is in flowering weeds or has a flowering crop in the vicinity, the product should only be applied using bee-safe technology.

The application rate is 500 to 1500 l/ha in vineyards and fruit crops depending on the type of crop, the size of the foliage and the type of machinery used, 300 to 1000 l/ha in potatoes, tomatoes and peppers depending on the size of the crop, and 150 to 300 l/ha in oilseed rape and oilseed rape depending on the crop and the location of the pests. In the case of waxy crops, the spray solution should be prepared with an adherence enhancer.

In ornamentals, a phytotoxicity test should be carried out before spraying.

For aerial application, the product should be applied at a rate of 50-70 l/ha of water (autumn and spring cereals, rape, potatoes, tomatoes, peppers, apple crops, stone fruit, vines, sweetcorn and fodder maize).


Distribution advice

Contact insecticide with pyrethroid activity. At application, coverage of 60-70 drops/cm2 should be achieved, which can be ensured by fine atomisation, i.e. 200-300 micron droplets should be generated. When spraying, care should be taken to ensure that the inner part of the plant, the leaf backbone, is covered with sufficient droplet coverage. Spraying should preferably be carried out with a double blade sprayer in arable fields and with an axial fan sprayer capable of delivering large quantities of air in standing crops (vines, fruit).

Nozzle Recommendation: Double blade nozzle, conventional or air-aspirated, but in the latter case operating at a pressure of around 4 bar.
