JKI and Syngenta test seed treatment

Crows and pheasants are very fond of cron and thus cause extensive damage to the sowing. The first growth stages are affected at least up to the 2 leaf stage. A typical damage pattern is torn out seedlings. The seed should be protected as much as possible from this.

We at SeedForward GmbH are developing an effective and bio-based seed protection that prevents bird feeding. We treat corn seed lots with repellent plant extracts and additives which are applied to the grains with the help of a bio-based polymer.

Their effectiveness as bird repellents is determined by feeding tests at the Institute for Plant Protection in Horticulture and Forestry of the Julius Kühn Institute under the direction of Dr. Esther. In multiple choice trials Joanna Dürger places the seeds of pheasants in aviaries. She also uses the field prognosis test to see whether the animals also spurn the seedlings of different stages in planting bowls.

The first scientifically compiled results, which are part of an authorisation as a biocide, substantiate our effect against bird feeding, which has now been observed for 3 years. The results show that the treated seed is very little eaten compared to untreated corn seed, similar to seed treated with Mesurol (see diagram). The effect is now expected to continue through the relevant growth phase. To optimise the repellent effect of the substances or their formulations for field use, further tests and field trials are to be carried out.

In summary, bio-based bird predation protection on seeds can be a possible alternative. This is what we would like to realise with our partners.

Bird feeding trials in corn, Syngenta, Switzerland

Site with significant bird predation (crows) and wireworm occurrence
Syngenta results, Switzerland 2020

Incidence of bird and wireworm damage was influenced by seed treatments
Results of a plot experiment with n = 6 replicates each
Variety: SY Feeditop; sowing date: 19.06.2020; 80 000 seeds/ha
Control, Korit and SeedForward with base fungicide treatment Redigo M (BCS) and Vibrance FS500

  • Compared to the control, bird predation and wireworm damage were reduced by Korit and by SeedForward’s seed treatment
  • On average, Korit and SeedForward’s seed treatment achieved comparable performance.

  • Plots treated with SeedForward’s seed treatment or Korit recorded higher plant numbers under bird predation pressure compared to control
  • On average, the number of established plants was comparable with both seed treatments under bird predation pressure

Average results from 11 different sites in France

  • At 11 sites with significant crow pressure, between 25% and 75% of the respective plant stands were damaged.
  • On average, 56% of the control plants were damaged. In contrast, plots with SeedForward’s seed treatment were damaged only 25%.
  • On average across the 11 sites, the number of damaged plants was reduced by 50% through the use of SeedForward’s seed treatment.
