Mode of action of fluopyram in plant-parasitic nematodes.

Plant-parasitic nematodes (PPN) are responsible for severe yield losses in crop production. Management is challenging as effective and safe means are rare. Recently, it has been discovered that the succinate dehydrogenase (SDH) inhibitor fluopyram is highly effective against PPN while accompanying an excellent safety profile.

Phytostabilization of a contaminated military site using Miscanthus and soil amendments.

Military activities can contaminate productive land with potentially toxic substances. The most common trace metal contaminant on military bases is lead (Pb). A field experiment was begun in 2016 at Fort Riley, KS, in an area with total soil Pb concentrations ranging from 900 to 1,500 mg kg and near-neutral pH.

First record of the ectoparasitic nematode (Nematoda: Tylenchida) on the perennial grass × (Angiosperms: Poaceae) in Ukraine.

The growing interest in biomass production of  ×  () (Poaceae) on agricultural and marginal lands has prompted researches to identify plant pathogens and diseases affecting this crop which has a great potential for production of biofuels and different bioproducts. A soil survey of nematodes in the rhizosphere and a report on the collection of the plant-parasitic nematode (Belonolaimidae) were accomplished in two locations in Ukraine. It is known that this family of nematodes can reduce the root system and biomass of Poaceae family plants.

Multiyear phytoremediation and dynamic of foliar metal(loid)s concentration during application of Miscanthus × giganteus Greef et Deu to polluted soil from Bakar, Croatia.

The multiyear cultivation of Miscanthus × giganteus Greef et Deu (M.×giganteus) at the soils polluted by metal(loid)s were researched. The biomass parameters and concentrations of elements: Ti, Mn, Fe, Cu, Zn, As, Sr, and Mo were determined in the plant's organs at harvest.

The ecological risk assessment of soil contamination with Ti and Fe at military sites in Ukraine: avoidance and reproduction tests with Folsomia candida.

The aim of this research was to assess the effect of soil contamination with titanium (Ti) and iron (Fe) at military sites in Ukraine using the avoidance and reproduction tests with Folsomia candida (springtail). The soil used for the tests was sampled in 2017 from Dolyna, Ivano-Frankivsk region, Ukraine from two plots, namely a contaminated and a control site. The sample site is a former military site previously used for tank training.

Impact of plant growth regulators and soil properties on Miscanthus x giganteus biomass parameters and uptake of metals in military soils.

The impact of plant growth regulators (PGRs) "Stimpo" and "Regoplant" on Miscanthus x giganteus (Mxg) biomass parameters was investigated when the plant was grown in military soils with different properties from Dolyna, Ukraine and Hradcany, Czech Republic. The results showed that PGRs positively influenced the biomass parameters when the plant was grown in soil in Dolyna with good agricultural characteristics, the influence of "Regoplant" was higher and the best results were obtained with combined treatment: application to rhizomes before planting and spraying on the biomass during vegetation. Using of PGRs did not improve the biomass parameters when the plant was grown in poor soil in Hradcany.

Potential phytomanagement of military polluted sites and biomass production using biofuel crop miscanthus x giganteus.

This study aims to summarize results on potential phytomanagement of two metal(loid)-polluted military soils using Miscanthus x giganteus. Such an option was tested during 2-year pot experiments with soils taken from former military sites in Sliač, Slovakia and Kamenetz-Podilsky, Ukraine. The following elements were considered: As, Cu, Fe, Mn, Pb, Sr, Ti, Zn and Zr.

Comparative assessment of using Miscanthus × giganteus for remediation of soils contaminated by heavy metals: a case of military and mining sites.

Contamination of soil by heavy metals is among the important environmental problems due to their toxicity and negative impact to human health and the environment. An effective method for cleaning the soil from heavy metals is phytoremediation using the second-generation bioenergy species Miscanthus × giganteus. The purpose of this research is to study the benefits of M.

The estimation of Miscanthus×giganteus' adaptive potential for cultivation on the mining and post-mining lands in Ukraine.

The possibility of Miscanthus×giganteus cultivation as an energy crop on the different types of mining rocks was studied. It was revealed that a loess-like loam and red-brown clay with the added black soil were the most suitable for plant growing. The yield of dry above-ground biomass ranged from 4.

SOME ASPECTS OF THE NATURAL CONTROL OF PLANT PARASITIC NEMATODES IN SOIL UNDER BROAD BEAN VICIA FABA L. CULTIVATED IN CROP ROTATION AND LONG-TERM MONOCULTURE.

Observations on population density of plant parasitic nematodes occurring in rhizosphere of broad bean cultivated in the crop rotation and long-term monoculture were performed during 2013-2014. 13 species were observed: Trichodorus primitivus, T. viruliferus, Paratrichodorus pachydermus, Criconema annuliferum, Paratylenchus projectus, Bitylenchus dubius, Merlinius brevidens, Pratylenchus fallax, P.

THE POTENTIAL FOR USING ENTOMOPATHOGENIC NEMATODES TO CONTROL DARKWINGED FUNGUS GNATS BRADYSIA COPROPHILA (LINTNER) ON SUCCULENTS IN GLASS HOUSES.

Darkwinged fungus gnat Bradysia coprophila Lintner (Diptera: Sciaridae) is known as a pest of ornamental plants in commercial green and glass houses in nurseries worldwide. There have been reports about significant Bradysia coprophila damage of succulent plants in five Botanical gardens in Ukraine, including Academician Fomin's Botanical garden (Kiev) for the last three years. In pot experiments the commercial strain of S.

MISCANTHUS X GIGANTEUS AS A NEW HIGHLY EFFICIENT PHYTOREMEDIATION AGENT FOR IMPROVING SOILS CONTAMINATED BY PESTICIDES RESIDUES AND SUPPLEMENTED CONTAMINANTS.

Soil monitoring was accomplished at 76 former pesticide storehouses in Kazakhstan. Gas chromatography analysis was limited to the organochlorine pesticides DDT (p,p'-dichloro-diphenyl-trichloroethane) and HCH (hexachlorocyclohexane), and their associated metabolites and isomers: 2.4'-DDD (p,p'-dichlorodiphenyl dichloroethane); 4.

EVALUATION OF VIRULENCE OF STEINERNEMA CARPOCAPSAE TO EUROPEAN MOLE CRICKET GRYLLOTALPA GRYLOTALPA L.

Common European mole cricket (CEML) Grillotalpa grillotalpa L causes damage to field, vegetable crops, and small fruits growing at commercial plantations and nurseries. Chemical control if insecticides are used in poison bates, soil application or seedling/bulbs treatment is not environmentally friendly. Inundative and innoculative release of CTVL biocontrol agents, in particularly, Entomopathogenic nematode is a reliable alternative to chemical control.

Host range and infectivity of Heterorhabditis bacteriophora (Heterorhabditidae) from Ukraine.

Entomopathogenic nematodes (EPNs) in the genera Steinernema and Heterorhabditis (Rhabditida: Steinernematidae and Heterorhabditidae, respectively) represent a most promising group of pathogens that are lethal to many soil-inhabiting insects. Ukraine has Lagged behind of Eastern European countries in apply studies of entomopathogenic nematodes. Recently, Heterorhabditis bacteriophora were extracted from soils in the Central Forest Steppe areas of Ukraine using Galleria mellonella traps and identified with PCR.

Diamondback moth in Ukraine: current status and potential for use biological control agents.

The Diamondback moth (DBM), Plutella xillostella (Linnaeus) (Lepidoptera: Plutellidae) is the insect pest damaging cabbage in Ukraine, especially in the Southern region. Biology, damage, population dynamics of diamondback moth and effect of natural enemies on the level of infestation of this pest by parasitoids and pathogens were studied in 2004-2007 in the laboratory and field conditions. Obtained results show that in general the pest has 2-3 generations, although up to 5-6 can evolve in the South.
