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 ... -
Temperature Effects on Cuscuta campestris Yunk. Seed Germination
Studies of biological characteristics of seeds and conditions for their germination have a major importance for planning and executing rational measures of weed control. The aim of this study was to investigate the effect ... -
Testing Sunflower Inbred Lines for Tolerance to Phoma Black Stem
Phoma black stem is caused by a widespread pathogen Phoma macdonaldii Boerema. The disease occurs regularly, causing damage by early defoliation and premature ripening. Complete resistance of sunflower to this disease ... -
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 ... -
Tolerance of Several Novi Sad Sunflower Hybrids to Phomopsis Stem Canker under Natural Infection
Sunflower diseases have a major impact on sunflower yield and quality of seed. When conditions during vegetation are favorable, the intensity of damage can be very high. Therefore, surveys of economically important ... -
Tomato Spotted Wilt Virus – One of the Most Destructive Plant Viruses
Tomato spotted wilt virus (TSWV) has one of the largest host ranges among plant viruses and is widespread in all climates. TSWV is responsible for numerous epidemics in many parts of the world in different crops, mainly ... -
Tuta absoluta (Meyrick, 1917) (Lepidoptera, Gelechiidae): a New Pest of Tomato in Serbia
Tomato leaf miner Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae), a devastating pest of tomato originating from South America has been recorded in Serbia on three localities: in tomato main greenhouse and open ... -
Uncinula necator (Schow) Burr., the Causal Agent of Grape Powdery Mildew: Economic Impact, Epidemiology and Control
The article is an overview of what we know at present about the patogen Uncinula necator and the disease powdery mildew of grapevine, i.e. its economic status, inoculum source, microclimate conditions, vine susceptibility ... -
Uncinula necator (Schow) Burr., the Causal Agent of Grape Powdery Mildew: Infection Potential and Microclimate
Microclimate in Podgorica vineyards and its effect on the formation, maturing and rupturing of cleistothecia, and disease outbreak, was studied. An analysis of collected data on minimum and maximum temperatures and ... -
Uncinula necator (Schow) Burr., the Causal Agent of Grape Powdery Mildew: Role of Winter and Early Spring Treatments
Three preceding articles (Miladinoviæ et al., 2007a, 2007b, 2007c) covered the state-ofthe art on the pathogen and disease, the source of inoculum and pathogen infection potential, and the microclimatic conditions of ... -
Uncinula necator (Schow) Burr.: Efficacy of Several Fungicides under Production Conditions and on Scions
The efficacy of several fungicides based on sulphur, propiconazole, kresoxim-methyl and pyrazophos was examined under production conditions and on scions in Podgorica environs over three successive years (2002, 2003 and ... -
Uncinula necator (Schow) Burr.: Source of Inoculum in Podgorica Vineyards
A study series has been organised to survey the present knowledge of the pathogen and disease, as well as microclimatic conditions in Podgorica vineyards, to examine the importance of winter treatments, proper choice of ... -
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 ... -
The Use of Vegetative Compatibility Tests for Identification of Biodiversity of Phytopathogenic Fungi
Visual assessment of phenotypes, performed when two strains of one fungal species are cultivated in a mixed culture on specific media, is known as vegetative or heterokaryotic compatibility or incompatibility test, which ... -
