The fungicide Tilt (propiconazole) applied to spring wheat between Zadoks growth stages 47 and 55 significantly decreased the severity of foliar diseases caused by Septoria nodorum and Erysiphe graminis and prolonged duration of green leaf area. Ther

This study was carried out to provide more detailed information about the toxicity of foliar-applied urea on the development of the fungus Septoria nodorum Berk. in wheat, and to examine the interaction between urea and infection on the formation of

Effects of Septoria nodorum on the grain yields and yield components of three spring wheat cultivars were studied in Finland using artificial field inoculation over three years. At low infection level, in 1986, grain yield was reduced in all cultivar

Twelve Finnish and foreign winter wheat cultivars and breeding lines were evaluated for resistance to Septoria nodorum at seedling and adult plant stage. Flag leaf severity varied between 6.5 and 20 % and ear severity between 2.5 and 10 %. In general

Assessment of susceptibility of spring wheat cultivars and breeding lines to Septoria nodorum was studied using detached seedling leaves mounted on benzimidazole agar. The results showed that all Finnish cultivars were fairly susceptible. The most re

The F2 progeny of two spring wheat crosses involving susceptible and moderately resistant parent cultivars were tested in the field for their reaction to infection by Septoria nodorum Berk. The variation in symptom expression was continuous, providin

Epidemic development of Septoria nodorum was studied in pure stands and mixtures of two spring wheat cultivars Tähti (susceptible) and Kadett (moderately resistant) in 1983—1985. Apparent infection rates in the mixture were similar to that of the
