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, ... -
Management of Western Corn Rootworm (Diabrotica virgifera virgifera)
Western corn rootworm (WCR) was registered for the first time in Europe near the Surčin international airport in Serbia in 1992. The spread of WCR on the territory of Serbia and its population density increased fast. The ... -
Virus Elimination from Ornamental Plants Using in vitro Culture Techniques
Viruses are responsible for numerous epidemics in different crops in all parts of the world. As a consequence of their presence great economic losses are being incurred. In addition to the development of sensitive ... -
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 ... -
Screening Test for Detection of Leptinotarsa decemlineata (Say) Sensitivity to Insecticides
In 2009, the sensitivity of 15 field populations of Colorado potato beetle (Leptinotarsa decemlineata Say.) - CPB was assessed to chlorpyrifos, cypermethrin, thiamethoxam and fipronil, four insecticides which are mostly ... -
The Use of GIS Methodology in Jumping Plant Lice (Hemiptera: Psylloidae) Studies in Serbia
Entomofaunistic studies contain a large number of data regarding the number of collected species, the number of individuals within species, time of collection, localities, species biology and morphology natural enemies ... -
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 ... -
Pathogenicity of P. terrestris on Maize Seedlings
Pathogenicity of P. terrestris was determined by the Knop’s medium slants method in test tubes. Isolates originated from the roots of maize (Zea mays L.), barley (Hordeum vulgare L.), Johnson grass (Sorghum halepense ... -
The Possibilities of Slovakian Pyrethrum Production
This paper discusses possibilities for pyrethrum Chrysanthemum cinerariaefolium (Trevir.) Vis. production in southern regions of Slovakia, with an emphasis on target marketing, management constraints and further research. ... -
Rhagoletis cerasi Loew (Diptera: Tephritidae) – Biological Characteristics, Harmfulness and Control
The European cherry fruit fly, Rhagoletis cerasi Loew (Diptera: Tephritidae), is a highly destructive pest in sweet and sour cherry orchards with a distribution area throughout Europe and the temperate regions of Asia. ... -
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 ... -
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 ... -
Thermodynamic Characterisation of Early Phytotoxic Effects of Sulfonylurea Herbicides to Maize Lines
Variations in susceptibility of maize lines to herbicides depend on different factors. Visible signs of phytotoxicity do not occur in the first few days after application when plants are tolerant to some herbicides. The ... -
Taxonomic Diversity of Fungi Associated with Some PCN Populations from Serbia
Increased content of pesticides in food chain resulted in using microorganisms as agents of biological control. The potato cyst nematodes (PCN) - Globodera pallida and G. rostochiensis belong to the group of the most ... -
Multiresidue Analysis of Pesticides in Soil by Liquid-Solid Extraction Procedure
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 ... -
Application of Liquid Chromatography with Diode-Array Detector for Determination of Acetamiprid and 6-chloronicotinic Acid Residues in Sweet Cherry Samples
