“…Sharp eyespot usually occurs more often in continuously cropped cereals, including particularly wheat (Colbach et al 1997;Żółtańska 2005). White mustard used at Mochełek as the pre-preceding crop seemed not to contribute to disease suppression, although volatiles released from breakdown of thioglycosides have shown activity against soil-borne pathogens (Larkin et al 2011). Low nitrogen rates at Mochełek did not decrease disease incidence as reported by Colbach et al (1997).…”

Sharp eyespot caused by Rhizoctonia cerealis was assessed in four winter wheat crops surveyed at four locations in north-central Poland in [2006][2007][2008][2009]. At the four locations symptoms developed on 41.9-67.7 % of shoots of all plants (average of 4 years) and on 49-73.5 % of shoots of diseased plants (average of 4 years). Slight (category 1) disease was most frequent, occurring on 24.4-41.3 % of shoots (range 14.8-51.3 %); moderate (category 2) disease was less frequent, occurring on 16.9-25.5 % of shoots (range 8.9-32.4 %); severe (category 3) disease was least frequent, occurring on 3.2-7.1 % (range 0-22.0 %) of shoots. Sharp eyespot affected wheat growth and yield, and grain quality. Disease, especially in the severe category, was associated with significant decreases in plant and ear dry weights, number of grains per ear, grain dry weight per ear and thousand-grain weight, and with increases in grain protein and wet gluten contents, Hagberg falling number and sedimentation value. There was an association between occurrence of sharp eyespot in stems and colonization of grain by fungi. Alternaria alternata and E. nigrum were the most common species.

“…The lower incidence and severity of disease at Dębina, Kończewice, and Minikowo may have resulted from the use of winter oilseed rape as the preceding crop. Volatiles released from the breakdown of thioglycosides produced by oilseed rape have shown antagonistic activity towards soil-borne pathogens (Larkin et al 2011). Yellow and narrow-leaved lupins, used as the preceding crop at Chrząstowo, do not produce compounds that could inhibit the growth and activity of Rhizoctonia.…”

Abstract:In the field study period from 2006 to 2010, the incidence and severity of sharp eyespot caused by Rhizoctonia were recorded on 36 cultivars of triticale at the milk ripe growth stage. Four localities in north-central Poland were included: Chrząstowo, Dębina, Kończewice and Minikowo. The susceptibility of the seedlings of 30 cultivars of triticale to R. cerealis (AG-D subgroup I) and R. solani (AG-5) was studied in the laboratory. There was much variation in incidence and severity of sharp eyespot between years and locations. The disease was most intense at Chrząstowo. At this location, the mean percentage of diseased stems on 28 cultivars was Most symptoms developed on coleoptiles, with less symptoms on the leaves and the least on the roots. There was much variation in susceptibility of triticale cultivars to both Rhizoctonia species. Cultivars were grouped into six categories according to the intensity of seedling infection. Categories 1, 2 and 3, representing low, moderate and high susceptibility to R. cerealis, included 17, 10 and 3 cultivars, respectively. Categories 4, 5 and 6, representing low, moderate and high susceptibility to R. solani, included 3, 12 and 15 cultivars, respectively. Cultivars Baltiko and Zorro had low, and cv. Cultivo had high susceptibility to both Rhizoctonia species. No cultivar was resistant to Rhizoctonia. There was a positive correlation between infection by R. cerealis and R. solani. Infection of coleoptiles by R. cerealis or R. solani was significantly correlated with infection of leaves. No correlation between intensity of sharp eyespot on triticale plants in the field and on seedlings in controlled conditions was found.

“…Certain plants have been shown to produce chemicals that act as biofumigants, controlling or reducing harmful soil fungi, similar to those that may cause charcoal rot. Bacterial control of diseases has been used successfully in potato (Larkin et al, 2011) and cacao production (Melnick et al, 2008). Mengistu et al (2009) showed some suppression of charcoal rot infestation with altered tillage and use of rye as a cover crop.…”
