Pathogen causing Phalaenopsis soft rot disease - 16S rDNA and virulence characterisationOriginal Paper

Plant Protect. Sci., 2018, 54(1):1-8 | DOI: 10.17221/18/2017-PPS
The pathogen causing Phalaenopsis soft rot disease and developed detached leaf inoculation methods were identified. Based on its 16S rDNA sequences, the pathogen causing soft rot disease in Phalaenopsis was Erwinia chrysanthemi/Dickeya chrysanthemi. Both virulent and avirulent strains were revealed. The detached leaf inoculation assay for E. chrysanthemi/D. chrysanthemi resistance evaluation included wounding and inoculating the detached leaf with 108 CFU/ml of bacteria. Soft rot disease symptoms in the inoculated detached leaf were measurable at 20 h after inoculation. The detached leaf assay was...

To develop new natural fungicides, six monoterpenes and two phenylpropenes were tested for their antifungal activity against eight plant pathogenic fungi. The results of the mycelial growth inhibition assay showed that trans-cinnamaldehyde was the most potent compound against the eight tested fungi with EC50 values ranging between 0.75 and 3.19 mg/l. This compound caused the higher mycelial growth inhibition than carbendazim. Furthermore, (-)-menthone exhibited strong antifungal activity against Alternaria solani (EC50 = 9.31 mg/l), Penicillium digitatum (EC50 = 16.14 mg/l), and...

The treatment of cucumber plants with Trichoderma atroviride TRS25 (TRS25) provided protection against infection by Rhizoctonia solani. In plants inoculated with the pathogen, nontreated with Trichoderma, disease symptoms were observed on the roots, shoots, and leaves while in plants treated with TRS25 the spread of the disease was limited. The induction of systemic defence response in cucumber against R. solani infection seemed to be strongly related to the enhanced synthesis of phenolic compounds in plants. HPLC analysis indicated remarkable increases in the concentrations of 23 phenolics belonging to hydroxybenzoic...
Resistance of winter wheat cultivars to eyespot and characterisation of causal agents of the diseaseOriginal Paper

The reaction of ten winter wheat cultivars grown in the Czech Republic to inoculation with Oculimacula yallundae and Oculimacula acuformis was evaluated in a small plot trial. In a parallel field trial the natural occurrence of stem-base disease complex in six of the tested cultivars was assessed. Lower severity of eyespot (and/or stem-base diseases) was observed in cultivars possessing the resistance gene Pch1 (cvs Hermann, Annie, Princeps, Manager, and Rebell) in plots inoculated with Oculimacula spp. as well as in natural field conditions. A total of 468 wheat stem bases from the Czech Republic was screened by...
Influence of 90-year potato and winter rye monocultures under different fertilisation on soil mitesOriginal Paper

The influence of the cultivation of a single crop (potato or winter rye) on mite assemblages was evaluated. Both crops were cultivated in a long-term monoculture (90 years). The response of mites to fertilisation treatment (mineral with manure or mineral alone) was also studied. It was hypothesised that the density of mites as a community and the density of particular mite groups are higher in winter rye crop in comparison with potato. Secondly, the fertilisation with manure is more beneficial for mites than the use of mineral fertilisers alone, both in winter rye and potato crops. Results showed significantly higher mite abundance in potato, mainly...
Goji berry gall mite Aceria kuko occurrence in the Czech Republic - short communicationShort Communication

Damage caused by the Goji berry gall mite, Aceria kuko (Kishida, 1927) was observed on the leaves of Lycium chinense Miller (Solanaceae) in Brno in August 2016 and on L. barbarum L. in Popovice in September 2016. Aceria kuko is a pest of Asian origin which is common in China and occurs only sporadically on Goji berry plants in the European Union. This is the first observation of the Goji berry gall mite occurrence in the Czech Republic.
The most northern record of the alien composite thrips Microcephalothrips abdominalis in Europe - short communicationShort Communication

The most northern record of Microcephalothrips abdominalis (Crawford, 1910) (Thysanoptera, Thripidae) in Europe and the first record in Slovakia was described. The climate change induced introduction in synergy with biological commodity trade globalisation may support the ability of exotic elements to establish adequate populations with suitable fitness. The main threat consists in at least temporary survival in mild climate ecosystems dispersing from artificially heated interiors with the potential to transmit economically important viruses, such as Tobacco streak virus.
Patterns of resistance to AHAS inhibitors in Limnocharis flava from MalaysiaOriginal Paper

Limnocharis flava (L.) Buchenau is among the most problematic rice weeds in Malaysia and is also reported to have developed multiple resistance to AHAS inhibitor bensulfuron-methyl and synthetic auxin 2,4-D. In this study, resistance across different AHAS inhibitors was characterised in a L. flava population infesting rice fields in Pulau Pinang, Malaysia. Dose-response experiments were conducted to determine the level of resistance to sulfonylureas, imidazolinone, triazolopyrimidine, and pyrimidinyl-thiobenzoate. Cross-resistance across different AHAS inhibitors was observed in the resistant L. flava population, exhibiting...

Weed emergence models require the estimation of base temperature for germination (Tb) that was estimated for Abutilon theophrasti, Echinochloa crus-galli, Amaranthus retroflexus, Sorghum halepense, Amaranthus albus, and Amaranthus hybridus in Iran, to calibrate an existing model called AlertInf. Two statistical procedures were adopted: Model 1 ‒ linear regression of germination rate and Model 2 - probit analysis. Model 1 provided lower Tb values. Abutilon theophrasti and A. hybridus presented lower Tb values (about...
