In 2007-2012 the first detailed study of P. halstedii distribution and severity was performed in the Czech Republic by monitoring altogether 128 localities. Incidence of the pathogen was recorded at seven localities in south-eastern (Central and South Moravia) and central parts (East and Central Bohemia) of the country; at only four localities the occurrence of sunflower downy mildew symptoms and pathogen sporulation were recorded repeatedly. In all cases the primary infection prevailed, and the severity of infections was rather low. The majority of records were for sunflower experimental fields (e.g. fields of Central Institute for Supervising...

The infection process of Cercospora zeae-maydis type II (syn. Cercospora zeina Meisel and Korsman) in resistant, moderately resistant and susceptible maize genotypes was studied in the greenhouse under artificial inoculation. The percent spore germination, germ tube growth and formation of mature appressorium on leaves at 24, 36, 48, and 72 h after inoculation did not differ between resistant, moderately resistant, and susceptible maize genotypes (P ≤ 0.05). More germlings were established after penetration on susceptible than resistant and moderately resistant maize genotypes at 72, 96, 120, and 144 h after inoculation....

The biochemical properties of proteases from the digestive system of the fig tree skeletonizer moth, Choreutis nemorana, were determined. Gut extracts of C. nemorana larvae were analysed using different specific peptide substrates and proteinase inhibitors. The optimal pH and temperature for proteolytic activities using azocasein as substrate were obtained as pH 11 and 45°C, respectively. In the case of N-benzoyl-l-arg-p-nitroanilide as substrate, the enzyme showed the maximum tryptic activity at pH 11. The kinetic parameters of trypsin-like proteases indicated that the Km and Vmax...

In 2010 and 2011, the efficiency of azadirachtin, applied as systemic trunk injections in the trunks of Platanus sp., was tested against Corythucha ciliata. Azadirachtin in the doses of 0.1 and 0.05 g of active ingredient per cm of diameter at breast height was applied in April. It was found that after application of both doses, the count of C. ciliata in plane-tree leaves significantly decreased. In 2010 and 2011, the average counted number of C. ciliata individuals in trees treated with the dose 0.1 g a.i./cm of dbh was 12.9 and 4.9, respectively, and 29.1 and 6.5 individuals, respectively, in trees treated with...
Bioactivity of selected plant powders against Prostephanus truncatus (Coleoptera: Bostrichidae) in stored maize grainsOriginal Paper

Crude powders of Azadirachta indica, Lantana camara, and Tephrosia vogelii, each at six concentrations (0.0, 2.0, 4.0, 6.0, 8.0, and 10% w/w), and Actellic SuperTM 2% dust were evaluated for repellence anti-feeding and toxicity to adult Prostephanus truncatus. Treatments were laid out in a completely randomised design with four replicates. Results showed that powders were strongly repellent (PR values 73.0-90.0%) and caused 46.2-52.2 and 69.7-85.6% reductions in grain damage and F1 progeny, respectively. Results showed that powders were weakly toxic to P. truncatus causing 40% kill 21 days after...
Control of Conyza spp. with glyphosate - a review of the situation in EuropeReview

Plant Protect. Sci., 2013, 49(1):44-53 | DOI: 10.17221/67/2011-PPS
In Europe, glyphosate resistant populations have developed in some weed species in perennial crops, including three species of the genus Conyza documented by the International Survey of Herbicide Resistant Weeds. Conyza spp. biology is reviewed in this paper and related to population dynamics and the development of resistant populations. Suboptimal growth stage at application, improper agricultural practices such as overreliance on glyphosate and long-term use of sublethal doses are identified as the most important factors of resistance development. Current control methods in perennial crops including mixtures of glyphosate with other...
