  • Assessment of microbial activity and biomass in different soils exposed to nicosulfuron 

    Santric, Ljiljana; Radivojevic, Ljiljana; Gajic Umiljendic, Jelena; Djurovic-Pejcev, Rada; Saric-Krsmanovic, Marija
    The effects of the herbicide nicosulfuron on the abundance of cellulolytic and proteolytic microorganisms, activity of β-glucosidase and protease enzymes, and microbial phosphorus biomass were examined. A laboratory ...
  • A Bioassay Technique to Study Clomazone Residues in Sandy Loam Soil 

    Gajic Umiljendic, Jelena; Radivojevic, Ljiljana; Djordjevic, Tijana; Jovanovic-Radovanov, Katarina; Santric, Ljiljana; Djurovic-Pejcev, Rada; Elezovic, Ibrahim
    A bioassay test was conducted to evaluate the sensitivity of maize, sunflower and barley to clomazone residues in sandy loam soil. Clomazone was applied at different rates from 0.12 to 12 mg a.i./kg of soil. The parameters ...
  • Chemical control of field dodder in alfalfa 

    Saric-Krsmanovic, Marija; Bozic, Dragana; Malidza, Goran; Radivojevic, Ljiljana; Gajic Umiljendic, Jelena; Vrbnicanin, Sava
    Parasitic flowering plants have recently come into focus of research interests as a result of their notable expansion and increasing damage that they are causing in agricultural fields. Damage caused by field dodder in ...
  • Comparison of Methods for Bifenthrin Residues Determination in Fermented Wheat Samples 

    Djordjevic, Tijana; Djurovic, Rada; Gajic Umiljendic, Jelena
    Efficiency of three different sample preparation methods for GC/MS determination of bifenthrin residues in wheat (Triticum spelta) samples fermented by Lactobacillus plantarum was tested. The first method was based on a ...
  • Efficiencies of Different Methods for Determination of Organophosphate Pesticide Residues in Fermented Wheat Substrate 

    Djordjevic, Tijana; Siler-Marinkovic, Slavica; Djurovic-Pejcev, Rada; Dimitrijevic-Brankovic, Suzana; Gajic Umiljendic, Jelena
    In the present work, the efficiencies of three different sample preparation methods for GC/ MS determination of pirimiphos-methyl and chlorpyrifos-methyl residues in wheat (Triticum spelta) samples fermented by Lactobacillus ...
  • Maize, Sunflower and Barley Sensitivity to the Residual Activity of Clomazone in Soil 

    Gajic Umiljendic, Jelena; Jovanovic-Radovanov, Katarina; Radivojevic, Ljiljana; Santric, Ljiljana; Djurovic, Rada; Djordjevic, Tijana
    Sensitivity of maize, sunflower and barley to clomazone residues in loamy soil was assessed in the study using bioassay. Clomazone was applied at a series of concentrations from 0.12 to 12 mg a.i./kg of soil. After 14 ...
  • Multiresidue Analysis of Pesticides in Soil by Liquid-Solid Extraction Procedure 

    Djurovic, Rada; Djordjevic, Tijana; Radivojevic, Ljiljana; Santric, Ljiljana; Gajic Umiljendic, Jelena
    A multiresidue method for simultaneous determination of four pesticides (diazinon, acetochlor, aldrine and carbofuran) belonging to different pesticide groups, extracted from soil samples, is described. The method presented ...
