Crows and pheasants are very fond of maize 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 maize 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, it can be said that biobased birdfeed protection on seeds can be a possible alternative. We would like to realise this with our partners.
