Between March 01 and 02 2011, Slovenian Plant Protection Society (heads of the organizing committee were Prof. Dr. Stanislav Trdan, president of the society, and Prof. Dr. Maja Ravnikar) organized jubilee 10th Slovenian Conference on Plant Protection in Podčetrtek. 76 oral presentations from 9 thematic sections (plenary lectures, roundtable lectures, protection of fruit crops, protection of vegetables and ornamental plants, protection in viticulture, plant protection products and environment, protection of field crops, protection of forest trees and other woody plants, GIZ phytophrmacy) were presented. In the poster section 28 topics from different fields of plant protection are presented. In the abstract volume 105 abstracts are presented in 105 pages in Slovenian and English. Lectures and papers, presented at the conference, contain 70 full papers in 397 pages. Editorial work in both proceedings was done by Acad. prof. Dr. Jože Maček and Prof. Dr. Stanislav Trdan. The latter with a help of Assist. prof. Matej Vidrih and Jaka Rupnik also performed technical work. 316 participants from all important Slovenian research, professional and administrative institutions from the field of agriculture have attend the Conference.
B.01 Organiser of a scientific meeting
COBISS.SI-ID: 257422080We conducted a block field experiment in Srebrniče in which we studied natural resistance of 14 hybrids and 6 varieties of cabbage to the attack of flea beetles (Phyllotreta spp.), cabbage stink bugs (Eurydema spp.) and cabbage moths (Mamestra spp.). In relation to the length of growing season, we planted and grow cabbage cultivars in the open from the end of April till the end of June (early cultivars), the middle of July (mid-early cultivars) and the middle of August (mid-late cultivars). The extent of damage caused by the studied pests on leaves and heads of untreated and sprayed cabbage (we used only insecticides lambda-cyhalothrin and thiamethoxam) were determined with standard visual grades. Cabbage cultivar and way of control (sprayed/unsprayed) showed in both years to be significant factors in the extent of damage by the studied pests. Average indexes of damage on outer leaves of cabbage were by all studied pests significantly lower on plants sprayed with insecticides. The highest productivity was confirmed in mid-early cultivars and early cultivars proved to be less productive. When cabbage heads were attacked by cabbage moth caterpillars, far most susceptible were early cultivars and mid-late cultivars in this point of view showed the highest natural resistance. We established that the abundance of studied pests on cabbage is in great extent determined by crop rotation, wheater conditions, phenological growth stages of cabbage, way of production (absence/presence of insecticides) and cultivar choice. The latter namely with different morphological and biochemical parameters represent different but suitable environment for oviposition, reproduction and feeding of studied pests and which leads to different natural resistance or sucseptibility to their attack.
D.10 Educational activities
COBISS.SI-ID: 6681977On the workshop "Possibilities of environmentally friendly production of field crops, industrial and fooder crops and sustainable use of grasslands in Slovenia" results of alternative control methods against the bean weevil with diatomaceous earth, dust of field horsetail and lavender (first trial) as well as with essential oils of rosemary, bergamot orange, Camphor tree, bay laurel and common sage (second trial) are presented. Diatomaceous earth and essential oils of rosemary, bay laurel and common sage shower the highest insecticidal efficacy, therefore we suggest their use in the continuation of the trials in the warehouses.
