Abstract Leaf blotch of wheat is a widespread and highly active disease that affects production. In addition to the use chemicals proper cultivation methods, microbial antagonists are used control plant pathogens. Trichoderma spp. stimulate systemic induced response in plants. Therefore, efficacy against leaf was evaluated under greenhouse conditions. The susceptible plants were sprayed with Septoria tritici conidiospores. order select an efficient method pretreatment spp., spraying seed...
Abstract Nitrogen (N) fertilization is required for achieving high yields in wheat ( Triticum aestivum L.) but may enhance the development of Septoria tritici Rob. ex Desm. A study was undertaken to investigate how N supply influences area under disease progress curve (AUDPC). Two field experiments were carried out a typical argiudol 1996 and 1997. Six cultivars grown at two treatments (0 100–150 kg N/ha) split plot design. Percentage necrosis (severity) upper leaves each treatment evaluated...
Zero tillage often leads to wheat ( Triticum aestivum L.) yield losses from diseases caused by necrotrophic foliar pathogens. The aim of this work was evaluate the combined effect tillage, N fertilization, fungicides, and resistant cultivars in reducing disease severity prevent significant losses. A 2‐yr study including combinations (i) conventional zero tillage; (ii) fertilization rates 0, 80, or 160 kg ha −1 N; (iii) two fungicide treatments (with without a (1 L metconazole, 9%) at growth...
The relationship between resistance to Septoria tritici blotch with plant height and heading date has been in most cases attributed genetic associations. More efficient selection for higher levels of quantitative may result if the nature association susceptibility earliness shortness can be determined. Genetic its relationships were recorded 50 Argentinean wheat ( Triticum aestivum L.) cultivars three environments (two field one greenhouse) virulent isolate Mycosphaerella graminicola...
Coinoculation of plants with mixtures beneficial microbes sometimes produces synergistic effects. In this study, the effect soybean coinoculation N2-fixing Bradyrhizobium japonicum E109 and biocontrol fungus Trichoderma harzianum Th5cc was analyzed. Nodulation by not hampered Th5cc, which antagonized five out seven pathogens tested. Furthermore, relieved nitrate-inhibition nodulation, enabling formation nodules containing infected cells bacteroids in presence otherwise inhibitory 10 mM KNO3....
Abstract Four resistance components, i.e. incubation period, latent maturation period and pycnidial coverage, were studied in a diallel cross of four wheat cultivars differing susceptibility to Septoria tritici. Inoculations evaluations carried out at the fourth leaf stage for two years. A combined ANOVA both years exhibited significant interaction between crosses period. separate each year was done this trait. The showed that significantly different incubation, coverage. Cross effects also...
ABSTRACT Nitrogen fertilization is required for achieving high yields in wheat ( Triticum aestivum L.), but N may enhance the development of leaf blotch Septoria tritici Roberge Desmaz., teleomorph Mycosphaerella graminicola (Fuckel) J. Schröt. Cohn). The present study was undertaken to investigate how affects yield, yield components, and test weight (TW) different cultivars under supplies. Field experiments with six were carried out a split‐split plot design during 1996 1997. Inoculation...
Abstract The effect of six isolates Trichoderma harzianum and one isolate T. koningii on the incidence severity tan spot (Pyrenophora tritici-repentis) leaf blotch wheat (Mycosphaerella graminicola) was evaluated under field conditions. Significant differences between cultivars, inoculum types growth stages were found. Three tested (T2 for M. graminicola, T7 P. tritici-repentis T5 both them) showed best performance in controlling when coated onto seed or sprayed leaves at different stages,...
Leaf blotch of wheat ( Septoria tritici Rob. ex Desm., teleomorph Mycosphaerella graminicola (Fückel) Schröt. in Cohn) causes significant losses wheat. During the last decades studies about genetic variability pathogen and location resistance have been intensive around world. The knowledge variation M. is very important because it could allow us to determine which genotypes predominate within a geographic area. It also can be used evaluate germplasm cultivars with isolates high differences....
