The aim of this study was to estimate the effect of fungicides on the occurrence of Oculimacula spp. on winter wheat stems using real-time polymerase chain reaction (Real-time PCR) method. The ratio of Oculimacula yallundae and Oculimacula acuformis in the population was assessed from 2009 to 2011 in the winter wheat crops after 2, 3, and 4 years o...

Eyespot, caused by Oculimacula acuformis and O. yallundae, is one of the most damaging diseases in areas, including Lithuania, where mild and damp autumn and winter conditions favour the development and spread of the pathogens. The aim of this study was to estimate the incidence of eyespot in Lithuania and to use real-time polymerase chain reaction...

Cereal yield loss from eyespot directly depends on the severity of the disease. The aim of this study was to establish the relationship between eyespot damage in winter wheat and components of yield of winter wheat cultivars Ada, Mulan and Tukan in Lithuania in the 2011/2012 cropping season. Several eyespot did not decrease the grain number per ear...

Eyespot of rye, caused by two fungal pathogens Oculimacula yallundae and O. acuformis, is widespread throughout many cool and wet cereal growing regions. The study was aimed to estimate eyespot incidence in winter rye crops in three agro-ecological zones of Lithuania, and to quantify eyespot disease causal agents O. yallundae and O. acuformis in th...

Mycosphaerella graminicola (Fuckel) J. Schröt. (anamorph Zymoseptoria tritici (Desm.) Quaedvlieg & Crous) causes Septoria leaf blotch disease of wheat. The disease can be responsible for yield losses of 30–50% and, when severe, requires management with a fungicide. Single picnidia isolates collected from different locations of Lithuania were tested...

During the period 2008-2010, in different soil and climate conditions: 1) in Middle Lowland of Lithuania in Dotnuva, 2) in Southeast Lithuania in Perloja, experiments were conducted to investigate the peculiarities of ascochyta blight control using seed treatment and fungicide application. Commercial seed from the same lot of the pea variety 'Pinoc...

During the period 2008-2010, experiments were conducted to investigate the severity of ascochyta blight in the crops of semi-leafless field pea (Pisum sativum L.) cultivars 'Profi', 'Eiffel', 'Simona', 'Tinker', 'Mascara' and 'Pinochio' in different soil and climate conditions of Lithuania: 1) on a Southeast Luvisol (LV) in Perloja, 2) on a Middle...

The seeds of the winter and spring wheat (Triticum aestivum L.) were subjected to a strong microwave electric field (SMEF) generated in a high power magnetron generator, working in a pulsed mode. Seed samples with different moisture contents (12, 15 and 18 %) were treated at the band 2.6, 5.7 and 9.3 GHz at 5, 10 and 20-minute exposures. Seed germi...

Research evidence suggests that in Lithuania eyespot incidence in winter wheat crops was from 33 to 60% annually. Climatic conditions are the most important factor influencing the infection of winter wheat by eyespot. The variation of the climatic conditions (rainfall and number of rainy days) in the autumn and spring, the incidence and disease sev...

Management of seed borne root and foot rot diseases of pea (Pisum sativum L.) through a seed treatment with Raxil extra (a.i. tebuconazole 15 g l -1 and thiram 500 g l -1) at a dose of 2.0 l t -1 and Kinto (a.i. triticonazole 20 g l -1 and prochloraz 60 g l -1) at a dose of 1.5 l t -1 was investigated during 2008-2010 under different soil and clima...

Fungicides are widely used to control pea diseases. We investigated non-target effects of fungicide seed treatment, applied at recommended rates, on soil bacteria and fungi counts in the rhizosphere and bulk soil in Lithuania from 2008 to 2010. Microbiological analyses were conducted on the soil samples of the rhizospheric and non-rhizospheric zone...

A total of 125 small grain samples, including 60 of winter crop and 65 of spring crop collected during 2006–2007 at harvesting in Lithuanian fields, were involved in the current study on co-occurrence of three Fusarium mycotoxins. All grain samples tested were found to be contaminated with mycotoxins. In 2006, winter cereal grain samples contaminat...

Abstract The study on the control of Fusarium head blight (FHB) in naturally infected winter rye and winter triticale crop was conducted at the Lithuanian Institute of Agriculture during the period 2004–2006. Our experimental findings indicate that the incidence of FHB, grain infestation with Fusarium spp. and mycotoxin deoxynivalenol (DON), zearal...

The effects of fungicides on Fusarium spp. and their associated mycotoxins in naturally infected winter wheat grain Field trials conducted at the Institute of Agriculture, Lithuanian Research Centre for Agriculture and Forestry (central part of Lithuania) in 2009 were aimed to evaluate the effect of fungicides on Fusarium Head Blight (FHB) in a nat...

Experiments conducted at the Lithuanian Institute of Agriculture in 2004-2005 were designed to investigate the contamination of winter rye cv. 'Duoniai' and triticale cv. 'Tornado' grain with fungi of genus Fusarium and mycotoxins produced by them as affected by the spray-applications of the crops with the fungicides propiconazole, tebuconazole, an...

Field experiments were conducted over 3 years to assess the effects of fungicides (F) containing strobilurins (alone and in mixture with morpholine, triazoles) and triazoles (epoxiconazole or propiconazole) on winter wheat ‘Zentos’ grain quality, incidence of Fusarium head blight (FHB) in the field, grain contamination with fungi and mycotoxins. Th...

The research was designed to study the use of a biological agent Biojodis for winter wheat and spring barley seed and plant treatment against seed borne fungal stem base and leaf diseases as well as against toxic fungi occurring on harvested grain. Seed treatment with Biojodis did not exert any effect on seed contamination with Fusarium spp.; howev...

Field trials were conducted in Dotnuva during 2005–2006 with the aim of determining the impact of fungicidal seed treatment on the severity of stem base and root rot diseases of pea. Seed treaters reduced the severity of stem base and root rot diseases in pea. The severity of stem base diseases of the plants that emerged from treated seed was lower...

Field experiments were conducted over 3 years to assess the effects of fungicides (F) containing strobilurins and triazoles on grain protein concentration, grain and protein yield of the winter wheat cv. ?Zentos'. The efficacy of F use on the parameters tested depended on the weather conditions of the harvest year and on the F applied. F use prolon...

The present study was designed to evaluate the characteristics of the incidence of Cercospora leaf spot, caused by Cercospora beticola Sacc. in sugar beet (Beta vulgaris L.) cultivars differing in resistance as affected by the environmental conditions. The trials were conducted during the period 2001–2005 at the Lithuanian Institute of Agriculture...

21 During the period 2003–2005, spring and winter cereal grain samples were analysed for the presence of the mycotoxins deoxynivalenol (DON), zearale-none (ZEN), T-2 toxin, ochratoxin A and aflatoxin (total) by the ELISA (enzyme-linked immunosorbent assay) method at the Lithuanian Institute of Agriculture. Mycotoxin DON produced by the fungi of the...
