Schad birds

Certain species of birds like throttle (Blackbird), pheasant, partridge, Sparrow and star have it at maturity from August or vintage Apart from the sweet grapes and can cause significant yield reduction. Bird plagues in the vineyards have been described since antiquity and are still a problem worldwide. In spring and summer they can be used as insectivores and thus as beneficials but be very welcome. In extreme cases, very large flocks of up to 10,000 birds and more can occur, this is particularly true of the star to. If such a flock of birds settles on a vineyard, it is "harvested" in a short time. As a negative side effect of damaged or pimped berries, the penetration of microorganisms such bacteria and mushrooms and thus the appearance of bunch rot favored.

Damselfish - Blackbird, Partridge, Star

Through various measures, attempts are made to prevent this or to limit the damage. The earlier use of ovicidal (Pesticides) is today severely restricted or even prohibited. As a substitute "vergrämungsmittel" (repulsives, repellents) are used, which are perceived by the sense of smell, but not kill. For this purpose, physical methods are also counted. A relatively complex form is the spanning of the vineyards with nets. Care must be taken that the nets are visible to the birds so that they do not fly and injure themselves.

But often they are optical devices like scarecrows Acoustic, wind-powered, noise-causing devices such as Klapotetz, Audio tapes with bird-shouts or gun shots, airplanes or personal surveillance by one Weingarten guardian, This is intended to spread the birds as possible to all the vineyards in a larger area and thus minimize the damage for all winegrowers. This will be part of the biological or. Integrated pest management used.
