Herbivorous land snail Arianta arbustorum Linnaeus, 1758 (Gastropoda, Pulmonata, Helicidae) has become considerable pest that occurs throughout Central, Eastern and Northern Europe. Commercially available neem formulation NeemAzal-T/S (containing 1 % azadirachtin, Trifolio-M GmbH, Germany) was tested on experimental white cabbage field of the Estonian University of Life Sciences against cabbage pests, including the snail A. arbustorum. The formulation was diluted with water and treated in concentrations 0.03 % and 0.3 % (solution/ spraying and watering) with weekly intervals. After that the number of snails started to grow and the highest population peak was in the middle of September. All the tested neem concentrations affected the number of snails on the cabbage and were significantly different from control variant. There was no significant difference between treated variants. Both, spraying and watering with NeemAzal-T/S, affected A. arbustorum as effective repellent. It can be concluded that all neem treatments could control the snail A. arbustorum.
