  In this study, mostly weeds, the effect of 22 plant`s extracts on germination of seeds from nine different weeds was investigated. Plants used were sampled with their leaves and flowers, in 2002, then plant extracts were obtained after they were ground and processed with methanol. The experiments were conducted in 9 cm diameter sterile petri dishes inside covered with sterile filter paper. Fifty seeds were placed in each of petri dishes. Acetone (10%) was used as the control. The seeds germinated were taken out from the petri dishes and counted in every three day during 21 days. Lepidium sativum L. was very slightly affected by the extracts. All the weeds extracts except Lolium temulentum L. were stimulated the seed germination of Descurania sophia L. Webb. Ex. Prant. at a different levels. Germination of Lolium perenne L. were inhibited most strongly by Salvia officinalis L., Laurus nobilus L. and Artemisia vulgaris L. The extracts of all the plants studied inhibited the germination of Abutilon theophrastii Medik, Amaranthus retroflexus L., Avena sterilis L., Rumex crispus L. and Trifolium repens L. It was concluded that some of these extracts may be used as herbicide to control the germination and growth of some other weeds.

  Beet necrotic yellow vein virus (BNYVV) and Beet soilborne virus (BSBV) are the important soilborne virus diseases in the production areas of sugar beet. A survey was carried out to detect these viruses in soil samples using bait plant test and double antibody sandwich-enzyme-linked immunosorbent assay (DAS-ELISA) and triple antibody sandwich-ELISA (TAS-ELISA) in sugar beet production areas in Tokat, Turkey in 2001. Of the 26 soil samples taken from 8 districts in Tokat province, it was found that 23 samples (85.5%) were infected with BNYVV and 24 samples (92.3%) with BSBV. In 2002, total 49 root samples were tested for the presence of these viruses by ELISA. The incidence of BNYVV (67%) was greater than that of BSBV (8%). Furthermore, in this study it was determined the relationships between physical and chemical properties of soils and the appearance of BNYVV and BSBV. But, it could not determine any connection between infectious potential of viruses and soil properties.
