PLANT PROTECTION PRODUCTS IN ORGANICGRAPEVINE GROWING

Pests and grapevine diseases in organic production are suppressedby preventive measures with a view to reducing the impact of the attack. Allowedsubstances acting on patogenous fungi, insects, mites and other harmful organismsare used, if appropriate. Insecticides of plant origin are used in the organicproduction of grapevine, as well as vegetable oils, powders and insecticidal soapsthat are selective, with a narrow range of effects and of lower toxicity, as well asbiological products. As a rule, such plant protection products require a morefrequent application. Copper-based and sulphur-based fungicides are still leadingproducts in suppressing grapevine diseases. Researches are directed to decrease thequantity of application and to find their replacement by also efficient fungicides.A special emphasis is put on researching the efficient fungicides for suppressingBotrytis bunch rot and factors causing grapevine wood diseases (Esca and Eutypa)in organic production. Along with copper and sulphur, different substances such asbicarbonates, plant extracts and oils, biological products being parasites,patogenous or diseases agent antagonists, and natural products such as milk andwhey are applied in the organic production of grapevine.
