    Dressing Sugarbeet

Seed protection in sugarbeets - advantages of seed pelleting

Since young, developing sugarbeets are especially sensitive to stress and are placed at their final spacing (11 – 12 plants/m²) during sowing, pest pressure is very high. Therefore, emergence safeguarding and long-lasting protection for the seedlings and the young beet plants must be ensured, which KWS achieves by pelleting and treating the seeds.

Benefits of seed pelleting:

  • Gentle attachment of the seed treatment to the seeds
  • Protection against diseases during field emergence and damage caused by pests
  • Depending on the pest occurrence, you can select various seed dressings when ordering your seeds
  • homogeneous seeds
  • simple and exact sowing with single grain drills
  • improved field emergence through special husk mass components

Based on these factors, seed treatment is the most important measure for protecting the beet
until it has developed to the point where it can fend off pests
on its own.

Structure of the sugarbeet seed pill

In the structure of the sugarbeet seed pill, four layers can be distinguished to differentiate the prepared seed:

  • Gentle attachment of the seed treatment to the seeds
  • Protection against diseases during field emergence and damage caused by pests
  • Depending on the pest occurrence, you can select various seed dressings when you order your seeds
  • homogeneous seeds
  • simple and exact sowing with single grain drills
  • improved field emergence through special husk mass components

Layer 1:

  • Using a film coating method, a thin layer containing the fungicide TMTD (active substance: thiram) is applied
  • Fungal pathogens still located on the seed (seed-borne) are killed by the disinfecting action

Layer 2:

  • Builds up the pellet being formed using solid and liquid shell mass components
  • Great effect on weight and shape of the pellet
  • Here, the shell mass components contain various germination- and emergence-promoting materials
  • Functions as spatial separator between the seed and the seed treatment, which is applied in the third layer (protection from phytotoxic effects)

Layer 3:

  • Use of an additional film coating process to apply a suspension containing insecticides and fungicides to combat seed-borne diseases
  • Protects the germinating seed from attack by various animal pathogens and fungi (Aphanomyces cochlioides and Pythium ultmum)

Layer 4:

  • Application of the pigmented coating using the film-coating method immediately after application of the third layer
  • Prevents abrasion of the seed treatment during the drilling process and protects the farmer from direct contact with seed treatment agents
  • Gives the KWS pellet its typical brilliant orange colour
  • Completion of the seed treatment with a brief drying process

Sugarbeet seed dressing

When ordering seeds, pay attention to adequate seed dressing. Providing an insecticide is an important measure for protecting the sugarbeet during its early development stage. Animal pests in particular can cause severe impairments in the early growth phase.

Low seed treatment application:
The treatments Janus Forte and Force Magna are only suitable as emergence safeguards for locations with low pest pressure.

High seed treatment application:
In the case of heavy pressure from soil-borne pests (e.g. wire worm) or persistent occurrence of pests (such as pygmy mangold beetle or aphids) it is advisable to select the seed treatments Cruiser & Force or Poncho Beta+. Both of these, in addition to safeguarding emergence, offer long-term protection until row closure, even from larger soil pests.

Insecticides in sugarbeets

Neonicotinoids

  • Comprehensive protection of all plant parts from sucking and biting pests
  • Active ingredient is distributed through the sap current

Pyrethroids

  • Active ingredient jacket around the seed grain protects from feeding
  • Pests that penetrate into the treated area are paralyzed or killed
  • Acts only in soil
  • Little protection for the hypocotyl
