Clavibacter michiganensis subsp. michiganensis, Bacterial Canker of Tomato: 2. Comparison of the Effectiveness of Extraction Procedures and Sensitivity of Methods for Detection in Tomato Seeds
Two seed extraction procedures, used for detection of Clavibacter michiganensis subsp. michiganensis (Cmm) in artifficially infested tomato seed lots, were evaluated. A comparison of the efficiency of pathogen detection ... -
Examination of Mutagenic Effects of GAL-57 Herbicide (Bentazone+Dicamba) Using Mouse Micronucleus Test
A micronucleus test was run to investigate mutagenic potential of the herbicide GAL-57, a formulated mixture of bentazone and dicamba. The test was applied to mice of both sexes (strain: CRL: NMRI BR) and the herbicide ... -
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 ... -
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 ... -
Cacopsylla picta (costalis Flor, 1861) (Förster, 1848) (Homoptera, Psyllidae) a New Jumping Plant Louse Species on Apples in Serbia
Until recently only one jumping plant louse species Cacopsylla mali Schm. has been described on apples in domestic literature. Over the past few years investigations of Psylloidea on apples in Serbia have proved incidences ... -
Pome Fruit Viruses in Bosnia and Herzegovina
Field surveys and laboratory tests were carried out to assess the sanitary status of pome fruit trees in Bosnia and Herzegovina. Field surveys were carried out in 10 orchards, two nurseries and one varietal collectione ... -
Headspace Solid Phase Microextraction in Pesticide Residues Analysis: 2. Apple Samples
Headspace solid phase microextraction method (HS/SPME), optimised previously for pesticide water solutions, was applied to trace residues of the pesticides chlorpyrifos, fenthion and bifenthrin in apple samples. One-hour ... -
Pesticides and Arthropods: Sublethal Effects and Demographic Toxicology
Insecticides and acaricides designed to control primary harmful insects and mites may also variously affect some other arthopods present in an (agro)ecosystem (e.g. secondary pests, predators, parasitoids, saprophytes, ... -
Identification of Potato Virus Y Strains in Tobacco Crops
Five viruses: Potato Virus Y (PVY), Tomato Spotted Wilt Virus, Cucumber Mosaic Virus, Tobacco Mosaic Virus and Alfalfa Mosaic Virus, of which PVY was predominant, were detected by serological testing of tobacco samples ... -
Determination of Resistance Levels of Myzus persicae (Sulzer) by Biochemical Methods
Peach/potato aphid Myzus persicae (Sulzer) has developed three mechanisms of resistance: overproduction of one or two closely related carboxylesterases (E4 and FE4), production of modified acetylcholinesterase (MACE and ...
