A study was conducted in a pure stand of lucerne (variety Viktoria) under natural weed infestation with shepherd’s purse (Capsella bursa pastoris (L.) Medic.) on a slightly leached chernozem soil under nonirrigated ... -
Detection of Colletotrichum acutatum Latent Infections in Strawberry Petioles and Leaves
Colletotrichum acutatum is the most significant agent of anthracnose strawberry fruit rot. Besides being a necrotrophic pest, it can spend a part of its life cycle as an epiphyte, in a form of latent infection. The ... -
Influence of Tomato Spotted Wilt Virus Uneven Distribution on Its Serological Detection in Tomato, Pepper and Ornamentals
Reliable detection of plant pathogens does not only mean the development of sufficiently sensitive laboratory techniques for their routine testing. Regardless of the sensitivity of applied methods, the proper selection ... -
Comparative Study of Properties of Different Pesticide Formulations of the Same Active Ingredient
Characteristics of two formulations of trifluralin, an emulsifiable concentrate (EC) and emulsion, oil in water (EW), the latter being a new formulation of our design, were investigated and compared. Attention was focused ... -
Concentrations of Heavy Metals in NPK Fertilizers Imported in Serbia
Concentrations of Pb, Cd, Cu and Mn in sixteen NPK fertilizers imported and widely used in Serbia were determined by flame atomic absorption spectrometry (AAS). The results show that contents of heavy metals varied ... -
Effects of Metribuzin on the Activity of Some Enzymes in Soil
Eeffects of metribuzin on the activity of some enzymes in soil was investigated. Trials were set up in the laboratory on a clay loam soil. Metribuzin was applied at 12.0, 24.0 and 60.0 mg/kg soil rates and soil samples ... -
Field Efficacy of Fluopicolide and Fosetyl-Al Fungicide Combination (Profiler®) for Control of Plasmopara viticola (Berk. & Curt.) Berl. & Toni. in Grapevine
The efficacy of new fungicide mixtures in controlling Plasmopara viticola in grapevine was evaluated in field trials. The efficacies of Profiler (fluopicolide + fosetyl-Al) and the standard fungicide Mikal Flash (fosetyl-Al ... -
Morphological and Pathogenic Characteristics of the Fungus Cladobotryum dendroides, the Causal Agent of Cobweb Disease of the Cultivated Mushroom Agaricus bisporus in Serbia
Twenty isolates were isolated from diseased fruiting bodies of Agaricus bisporus collected from Serbian mushroom farms during 2003-2007. The isolates formed white, cottony, aerial colonies on agar media. With age, conidia ... -
Susceptibility of Bean Genotypes to Xanthomonas campestris pv. phaseoli in Greenhouse Conditions
Plants of 17 bean genotypes were evaluated under greenhouse conditions for their reaction to X. campestris pv. phaseoli, the causal agent of common blight of beans, following leaf-spray inoculation with bacterial suspension ... -
