Cyclic Ketoenols – Acaricides and Insecticides with a Novel Mode of Action
Modern crop protection industry puts great efforts into the investigation and development of pesticides (insecticides, acaricides) with a novel mode of action, primarily because of increasingly important problem of ... -
Solid Phase Microextraction (SPME) in Determination of Pesticide Residues in Soil Samples
The basic principles and application possibilities of the methods based on solid phase microextraction (SPME) in the analysis of pesticide residues in soil samples are presented in the paper. The most important experimental ... -
Jumping Plant – Louse Cacopsylla (Hepatopsella) bidens (Šulc, 1907) (Hemiptera, Psyllidae) New Pest on Pear in Serbia
The problem of jumping plant – lice, an important pest on pear, appeared in the middle of the twentieth century and represents a direct consequence of pear cultivation on large areas with intensive application of ... -
Effect of Plant Growth Promoting Rhizobacteria on Ambrosia artemisiifolia L. Seed Germination
Soil bacteria are able either to stimulate or inhibit seed germination. If seed germination is stimulated, the seedlings of weed species emerge more uniformly, so that they could be killed in the next step of weed control. ... -
Rimsulfuron in Soil: Effects on Microbiological Properties under Varying Soil Conditions
The effects of rimsulfuron a sulfonylurea herbicide on the growth and activity of soil microorganisms under laboratory conditions was investigated in two soils. The application rates were: 0.2, 2.0 and 20.0 mg a.i kg-1 ... -

During the period 2008-2010, on the experimental field of the Institute of Forage Crops – Pleven, on slightly leached chernozem a study was conducted with the purpose to determine the selectivity of some herbicides to ... -
Presence and Distribution of Economically Important Potato Viruses in Montenegro
The research was carried out, in the period 2002-2004 in order to determine the presence and distribution of potato viruses at 12 different locations and on 9 different potato varieties grown in Montenegro. The research ... -
Sensitivity of Phytophthora infestans (Mont.) de Bary Isolates to Fluazinam, Fosetyl-Al and Propamocarb-hydrochloride
A survey of in vitro sensitivity of twelve isolates of the Phytophthora infestans to the fluazinam, fosetyl-Al and propamocarb-hydrochloride was conducted. The isolates were isolated from infeceted potato leaves collected ... -
Botrytis cinerea Control and the Problem of Fungicide Resistance
Botrytis cinerea, the causal agent of grey mould, greatly affects fruit, grapevine, vegetable and ornamental crops production. It is a common causal agent of diseases in plants grown in protected areas, as well as fruit ... -
Methods for Determination of Pesticide Adsorption Properties and Examination of Their Mobility in Soil
Pesticide destiny in soil depends on a number of factors, as well as on presence and intensity of the processes such as adsorption, degradation, evaporation, rinsing and leaching. Since adsorption processes govern ... -
Fatty acid analysis of Erwinia amylovora from Serbia and Montenegro
Automated method of fatty acid analysis was used to identify and study heterogeneity of 41 Erwinia amylovora strains, originating from 8 plant species grown in 13 locations in Serbia and one in Montenegro. All strains ... -
Raspberry bushy dwarf virus – a Grapevine Pathogen in Serbia
During a field survey in 2005 in vineyards and grapevine nurseries at localities in central Serbia, a few plants with unusual virus-like symptoms were observed. Leaf samples were analyzed by DAS-ELISA for the presence ... -
Plasmopara obducens – a New Threat to the Production of Impatiens walleriana in Serbia
During 2010, Impatiens walleriana plants with symptoms of downy mildew were collected in a greenhouse in the vicinity of Mionica, Kolubara District. Disease incidence was extremely high, approaching 100%, and wilting and ... -
