The production of virus free garlic plants from totally cvs. Jana, Mera and ecotype Zamojski was attempted by means of thermotherapy and meristem tip culture. The cloves and the aerial bulbils after hot air treatment in a growth chamber at 36°C for 30-35 days or at 26-28°C for 3-4 months in greenhouse were used to meristem tip culture on M. S. medium. In the 26-28°C treatment 19.5 % of meristems produced plants and 22.5 % of these were virus free. In the 36°C treatment 14.5 % of the meristems developed into plantlets and 34.6 % of them were virus free. The plantlets were indexed by "sap-dip" electron microscopy methods.

Characterisation of two-spotted spider mite (Tetranychus urticae Koch, Acari: Tetranychidae) response to aqueous extracts from selected plant species. Aqueous extracts from four plant species of known insecticidal activity on arthropods were tested against two-spotted spider mite females to describe their mode of action on the spider mite. The extracts effects on: (a) the mite establishment on host plant; (b) initiation of feeding (probing behaviour); (c) initiation of permanent feeding and (d) the mite mortality (a toxic effect) was measured using various experimental techniques. The highest toxic action was shown by NeemAzal-T/S (an extract from Azadirachta indica; production of Trifolio-M GmbH company) and repellent by water extract from Allium sativum and Urtica dioica. NeemAzal T/S also shown a strong activity as a feeding suppresant for T. urticae.
