Application of Liquid Chromatography with Diode-Array Detector for Determination of Acetamiprid and 6-chloronicotinic Acid Residues in Sweet Cherry Samples
A rapid and simple method for simultaneous determination of acetamiprid and its metabolite 6-chloronicotinic acid in sweet cherry samples has been developed. This residue analysis method is based on the reversed phase ... -
Comparison of Methods for Bifenthrin Residues Determination in Fermented Wheat Samples
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 ... -
Development of Water Based Pesticide System
It is well known that emulsifiable concentrates (EC), besides good properties have problem with a high solvent content thus are not environmental friendly and can cause problems for users. The interest in developing ... -
Differentiation of Pseudomonas syringae Pathovars Originating from Stone Fruits
Due to an overlapping host range, similar symptomatology and many common characteristics, Pseudomonas syringae pathovars originating from stone fruits can easily be misidentified. In order to select tests for rapid and ... -
Distribution Frequency and Incidence of Seed-borne Pathogens of Some Cereals and Industrial Crops in Serbia
A total of 41 species of fungi were isolated from seed samples of barley, maize, soybean, and sunflower collected at different locations in Serbia. The majority of detected species occurred on barley (35 of 41 species ... -
Fusarium oxysporum as Causal Agent of Tomato Wilt and Fruit Rot
Tomatoes are parasitized by a number of pathogens, including Fusarium oxysporum f. sp. lycopersici, causal agent of fusarium wilt. Fresh vegetable fruits can be contaminated with various fungi that produce mycotoxins, ... -
Genus Monilinia on Pome and Stone Fruit Species
Different species of the genus Monilinia are common plant pathogens that endanger pome and stone fruit production worldwide. In Serbia, two species of this genus are widely distributed – M. laxa and M. fructigena, while ... -
