APPLICATION OF NATURAL OIL IN IPM OF GRAPEVINE WITH SPECIAL REGARD TOPREDATORY MITES

Oil products are widely used in orchards and on grapevine as pesticide s, or adjuvants to pesticides. We aimed to get information on the effi cacy of formulated rape seed oil against phytophagous mites in grapevi ne and its effect on predatory mites. Formulated rape seed oil (TELMIO N(R)) from the Temmen GmbH, Germany was used in field trials at 0.5% a nd 1%. For phytophagous mites TELMION(R) had an efficacy of 90,1% and 91,2% for 05% and for 1%, respectively. For Phytoseiidae there was no side effect at 0.5% and 1%. For Tydeiidae there was no side effect at 0.5% and a moderate toxicity (43.1%) at 1%. On the basis of our result s TELMION(R) seems to fit well into integrated Pest Management or Orga nic Production in grapevine.
