Symptoms of GVA - Kober stem grooving disease were not observed in the infected grapevines (which had been grafted onto Kober 5BB rootstock). A partial genomic sequence of the GVA isolate, 1523 nucleotides long, was obtained. The sequence completely covers the genes for both a movement and a coat protein. Compared to the GVA sequences available in databases, the nucleotide identity reached 84%. The amino acid identity in the movement protein reached 88%, and 98% in the coat protein.

Division of Plant Health, Crop Research Institute, Prague-Ruzyně, Czech Republic Title: The incidence and spreading of Macrophomina phaseolina(Tassi) Goidanovich on sunflower in the Czech Republic Abstract: VEVERKA K., PALICOVÁ J., KŘÍŽKOVÁ I. (2008): . Plant Protect. Sci., 44: 127-137. The warm climate pathogen Macrophomina phaseolina (Tassi) Goid., which causes charcoal disease, has been reported in the Czech Republic since 1999. The aim of our work was to study the incidence of disease between 2000-2007 in the main sunflower growing regions and analyse the relationship between weather conditions and the occurrence of the pathogen. The first and highest incidence of disease was in the Žatec region. However, in the region south of Brno there was no disease in 2000, 2001 and 2003, and only individual low incidence in other years until 2007, when the disease was found in nine localities. The incidence of the disease is increasing year by year indicating a spread of the pathogen. The warm and dry periods throughout the end of July and August have promoted the disease. However in some years where weather conditions were favourable for the pathogen, in several cases no disease was found. It is assumed, that the pathogen was not yet present in these localities. Soil conditions are critical. Diseased plants are usually distributed in several dispersed groups in the stand, especially on higher and drier parts of the field. Disease is also often found on plants suffering from compressed roots. Diseased plants had poorly developed heads and seeds.

The incidence of black point kernels ranged between 0.2-2.4% in 2003 and 24.2-34.3% in 2004. The kernels' fungal contamination varied from 60% to 100%. Alternaria spp., F. poae and F. culmorum were isolated from all localities and all subsamples. Stemphylium vesicarium, Fusarium culmorum, F. graminearum, F. avenaceum, F. sporotrichioides, Microdochium nivale, Epicoccum nigrum, Penicillium spp., Aspergillus niger, Rhizopus nigricans and Cochliobolus sativus were isolated less frequently. Fungi of the genus Alternaria were the most dominant, followed by Fusarium and Microdochium among which F. poae was dominant. Irrespective of incubation temperature, the germinative capacity and coleoptile growth rate of discolored kernels were affected more in the wet and cold year 2004. The inhibition of germination and seedling viability was more pronounced at the incubation temperature 22°C than at 15°C. Inhibition of coleoptile growth rate was 0.12-3.12% in black point kernels collected in 2003, and 0.24-9.28% in those collected in 2004.

(Lepidoptera: Noctuidae) Abstract: The bio-rational insecticides Dipel 2x, BioFly, Agrin, BioGuard, Spinosad, Neemix, Mectin and Match were tested for their effect on 1st, 3rd and 5th instar larvae and egg masses (24, 48 and 72 h old) of the Egyptian cotton leafworm Spodoptera littoralis under laboratory conditions. The doses used were the recommended dose, half of the recommended dose and quarter of the recommended dose. All insecticides caused higher mortality in the 1st than in the 3rd and 5th larval stage, although Match, Mectin and Spinosad at all tested concentrations showed excellent efficacy against the 3rd larval stage of S. littoralis. Also, Match resulted in 100% mortality of 5th instar larvae at all tested concentrations. Moreover, these insecticides also strongly affected some biological parameters of treated 3rd and 5th instar larvae of S. littoralis. Egg masses of different ages (24, 48 and 72 h old) where dipped into the recommended dose of each insecticide and the mortality rates determined; eggs of different ages were affected similarly, with mortality rates of 83.4, 85.0 and 71.7%, respectively, after treatment with Spinosad compared to the control. In general, eggs 48 and 72 h old were less sensitive than 24 h old ones. A latent effect of the insecticides on egg hatchability of S. littoralis was observed only in Match and Neemix, with the average being 55.0% and 51.6%, respectively. Our results suggest that Match, Mectin and Spinosad are potentially potent compounds for control of S. littoralis.

Being native to the eastern parts of North America, its first European interception was recorded in 1989. Since then it has invaded greenhouses in most European countries, including Slovakia, where it was first recorded in inspected material at the Botanical garden in Košice. As a polyphagous thrips with a wide host range it may induce damage mainly on ornamentals, although if low in numbers it can be easily overlooked. The species is a suitable example where preventive steps against its spread have not been sufficient enough which, therefore, demands further monitoring. Remarks on morphology, identification, economical importance and control are also given.
