Using reverse transcription polymerase chain reaction, 160 sweet and sour cherry trees from a germplasm collection, orchards, and wild trees in the Czech Republic were screened for the presence of Cherry necrotic rusty mottle virus (CNRMV) and Cherry green ring mottle virus (CGRMV). The viruses were detected exclusively in sweet cherry trees in the germplasm collection, with CNRMV determined in two trees and CGRMV in four trees. Using next-generation sequencing, nearly complete genomic sequences (complete ORFs) were obtained for one CNRMV and three CGRMV isolates. Their relatedness to GenBank sequences of isolates from different countries...

Gamma irradiation has been shown to be an effective method of controlling plant bacterial and fungal pathogens, but data on its effect against plant viruses is limited. A mechanism for the inactivation of plant viruses by gamma irradiation has not been proposed. Gamma irradiation was evaluated for the inactivation of Cucumber green mottle mosaic virus (CGMMV) in Nicotiana tabacum plants. CGMMV infectivity decreased gradually in a dose-dependent manner, and the virus was completely inactivated at over 40 kGy. Transmission electron microscopy revealed that gamma irradiation disrupts the virion structure and degrades viral protein and...

Singh Pooja, Subramanian Babu
Plant Protect. Sci., 2017, 53(4):208-215 | DOI: 10.17221/107/2015-PPS
The reaction of IR 50, TRY 3, and IR 36 cultivars of rice to R. solani challenge, the causal agent of sheath blight, and its toxic metabolite was studied. Differential response of these cultivars to the pathogen and/or toxin inoculation was observed in detached leaf sheaths and greenhouse-grown plants. The observations were based on disease scoring, electrolyte leakage, and also microscopic views of infection cushions. The Osmyb4 gene expression was studied in the tissues from all these experiments and a correlation between the level of expression and disease response of the varieties was found at least in some experiments. The mechanisms...

Crown and root rot, caused by the Oomycete pathogen Phytophthora palmivora, has become a destructive disease of apricot and cherry in eastern Turkey. There are no currently registered fungicides labeled for its control. In greenhouse experiments conducted in 2012 and 2013, 1-year-old potted apricot rootstock Zerdali and cherry rootstock Mahaleb plants were treated either with foliar spray of fosetyl-Al (140, 160, and 180 g a.i./100 l) or phosphorous acid (187.5, 200, and 215 g a.i./100 l) or soil drench of 100 ml of metalaxyl-M (= mefenoxam)+mancozeb (12+192, 16+256, and 20+320 g a.i./100 l) one day after wound inoculation of crowns and roots....
Using the loess method to describe the effect of temperature on development rateOriginal Paper
Junhe Liu, Yan Yan, Mingfu Yu, Megha N. Parajulee, Peijian Shi, Jiayang Liu, Zihua Zhao
Plant Protect. Sci., 2017, 53(4):226-231 | DOI: 10.17221/83/2016-PPS
Temperature has a significant influence on development rates of insects and mites. Many parametric models were built to describe the temperature-dependent development rates. However, these models provided different shapes of the curves of development rate versus temperature. For different datasets, investigators have to spend much time on considering which the parametric model is the best for describing the temperature-dependent development rates. In the present study, we encourage investigators to use an important non-parametric model, the loess method, which belongs to local regression methods. The loesS method is used to fit some published data...
Efficacy of certain common ferns against red spider mite Oligonychus coffeae and tea mosquito bug Helopeltis theivora infesting teaOriginal Paper

In search for botanicals as an alternative remedy to synthetic chemicals in the pest control of tea plantations, ferns such as Adiantum raddianum, Asplenium aethiopicum, Cyclosorus interruptus, Dicranopteris linearis, Diplazium polypodioides, and Pteridium aquilinum were evaluated against the two major pests of tea, red spider mite Oligonychus coffeae Nietner and tea mosquito bug Helopeltis theivora Waterhouse, which are the foremost seasonal pests in tea fields, causing severe crop loss. Apart from synthetic chemicals, only the neem kernel extract is recommended in tea fields. The aqueous extracts of ferns were...

During 2014-2016, damage by the oriental chestnut gall wasp Dryocosmus kuriphilus Yasumatsu (Hymenoptera, Cynipidae) was found on sweet chestnut trees at 4 localities in Slovakia. Dryocosmus kuriphilus is a specific plant pest on Castanea spp. In Europe it is considered as the most harmful insect pest on Castanea sativa. It is the first report of the oriental chestnut gall wasp occurrence on chestnut trees in Slovakia.
First record of Halyomorpha halys and mass occurrence of Nezara viridula in Slovakia (Hemiptera: Heteroptera: Pentatomidae)Original Paper
Vladimír Hemala, Petr Kment
Plant Protect. Sci., 2017, 53(4):247-253 | DOI: 10.17221/166/2016-PPS
The brown marmorated stink bug, Halyomorpha halys Stål, 1855 (Hemiptera: Heteroptera: Pentatomidae), is recorded from Slovakia for the first time based on a 5th instar larva collected in the town of Štúrovo, Slovakia. The current distribution, economic importance and biology of the species are briefly reviewed. During the visit to Štúrovo, a mass occurrence of adults and larvae of the southern green stink bug, Nezara viridula (Linnaeus, 1758) (Pentatomidae), so far captured in Slovakia in 2014 only as a single specimen, was also observed. This observation confirms the presence of N. viridula as an established...

Ditylenchus weischeri was recently reported in the provinces of Manitoba and Saskatchewan, Canada. Populations of D. weischeri from creeping thistle (Cirsium arvense L.) in Manitoba and D. dipsaci from garlic (Allium cepa L.) in Ontario were examined for their potential to grow on callused carrot (Daucus carota subsp. sativus) disks, alfalfa (Medi- cago sativa L.) and creeping thistle callus tissues, and pure cultures of eight fungal species, Botrytis cinerea, Fusarium solani, Rhizoctonia solani, Verticillium dahliae, Sclerotinia sclerotiorum,...

The efficacy and selectivity of herbicides and tank-mix combinations at different application terms in Clearfield and ExpressSun sunflowers were evaluated. Five-plot field trials (2011-2015) were carried out in Prague. The efficacy of tribenuron (TBM) was excellent and quite rapid on Chenopodium album. Its efficacy on other tested dicot weeds ranged around 90%, depending on weather conditions and growth stages of weeds. Echinochloa crus-galli was not controlled by TBM. The tank-mix combination of TBM + propaquizafop (PQF) caused sunflower injury when applied in a very cold growing period. Under dry conditions, PQF efficacy on E....
