Abstract
Tanacetum cinerariifolium (Trevir.) Sch. Bip. is a species of great economic importance because it contains Pyrethrins – natural insecticides with the potential to be the ideal means for pest control. Soil samples from different soil types (Skeletic Fluvisols, Rendzic Leptosol, Luvic Chernozem, Chromic Luvisols, Dystric-Eutric Cambisol, Pellic Vertisols) have been studied in order to determine the physicochemical soil indicators and the regressions between the soil characteristics and seed germination. Four hundred seeds (4х100) were planted in each soil type (in pots) under controlled conditions. Reliable statistically significant regressions, both negative (bulk density, sand fraction, available phosphorus) and positive (total porosity, silt and clay fractions, pH(H2O), CaCO3, Total Kjeldahl Nitrogen, Soil Organic Mater) with regard to seed germination have been established. The seeds planted in Rendzic Leptosol have shown the highest germination percentage, and the ones planted in Skeletic Fluvisols have shown the lowest germination percentage. Key words: Pyrethrum cinerariifolium Trev., Chrysanthemum cinerariifolium Bocc, seed germination, soil.

The Dalmatian pyrethrum – Tanacetum cinerariifolium (Trevir.) Sch
T. cinerariifolium is indigenous to the eastern Adriatic coast, and is found in Croatia, Bosna and Herzegovina, and Montenegro [5, 8, 9]
Natural pyrethrins have the potential to be the ideal means in the fight against insect pests [11-13]
Summary
The Dalmatian pyrethrum – Tanacetum cinerariifolium (Trevir.) Sch. Bip., referred to as Pyrethrum cinerariifolium Trev., Chrysanthemum cinerariifolium Bocc [1, 2, 3] is a perennial herbaceous plant of the Asteraceae family [4, 5, 6]. Natural pyrethrins have the potential to be the ideal means in the fight against insect pests [11-13] They are very effective against a wide range of insects [4, 14-17] acting as a contact insecticide [5], and the probability that resistance will develop is low. Natural pyrethrins are with low toxicity to mammals and other warmblooded animals as they are broken down into inactive forms and quickly leave the body [5, 11, 19]. Being environmentally friendly, they are a leading insecticide in organic farming [5]. Pyrethrins are unstable and rapidly degrade when exposed to UV light, oxygen, water and increased temperatures [4, 5, 26]
