“…At higher N, fungal diseases could be an important limiting factor on yield increase, so more fungicides should perhaps be applied to reduce the risk of yield losses. This result is similar to the results obtained by Jordan et al (1989). In addition, the timing of nitrogen dressings had a significant effect on the progress of stem base and foliar diseases ( Clare et al 1990).…”

“…Disease control and the yield response of barley were greatest when fungicides were applied during a 3‐week period after the main nitrogen application in April. No additional yield benefits were obtained by carrying out two fungicide applications ( Jordan et al 1989). Hanus and Schoop (1987) showed that the application of fungicides also increased the wheat and barley yield potential, but the yield variability over the treatments remained the same, except for the high N application rate of >200 kg ha −1 .…”

The effect of fungicides and their combination on yield of barley under different nitrogen, slurry and tillage treatments was investigated at Hohenschulen Experimental Station near Kiel, Germany in 1991–97. Various fungicide treatments (no fungicide, and treatment with stem, leaf and ear fungicides and combinations of these), two nitrogen levels (120 and 240 kg N ha−1), two tillage systems (minimum and conventional tillage) and four slurry applications (no application, and autumn, spring and autumn plus spring applications) were used. On average, fungicide application increased barley yield by 1.1 t ha−1. The fungicide treatments could be classified into four types: (1) fungicides against stem diseases, which slightly increased yield by 0.25 t ha−1, very similar to the results for the untreated control; (2) leaf fungicides and ear fungicides applied separately, and fungicides against a combination of stem and leaf diseases, which increased yield by 1.0 t ha−1 on average; (3) fungicides against a combination of ear and stem diseases, which increased the yield by 1.22 t ha−1, and (4) fungicides against a combination of leaf and ear diseases and a combination of stem, leaf and ear diseases, which increased yield by 1.59 t ha−1 on average. The effects of fungicide on the yield were modified by crop husbandry. It can be concluded that application of fungicides against a combination of leaf and ear diseases could increase barley yield and reduce yield variation.

“…There is some evidence that the timing of N applications can also influence disease development (Jordan et al , 1989; Olesen et al , 2003 b ). Early applications of the main spring dose to winter barley resulted in a greater severity of foliar disease compared with delayed applications (Jordan et al 1989). Similarly, early applications to winter wheat increased the severity of yellow rust (Neumann et al , 2004), powdery mildew and Septoria (Olesen et al , 2003 a ) compared with later applications.…”

A great deal of information is available in the literature on the effects of nutrition on disease development in plants and crops. However, much of this information is contradictory and although it is widely recognised that nutrition can influence disease in crops, limited progress has been made in the manipulation of crop nutrition to enhance disease control. Achieving this aim requires a sound understanding of the effects of fertilisation on nutrient levels and availability in crop tissues, and in turn, how the nutrient status of such tissues influences pathogen infection, colonisation and sporulation. Some of these details are known for a number of crop plants under controlled conditions, but very little of this type of information is available for crops under field conditions. This review focuses on nitrogen, sulphur, phosphorus, potassium and silicon, examines the availability of these nutrients in plant tissues to support pathogen growth and development, and reviews the effects of the different nutrients on disease development. The review also examines the potential for manipulating crop nutrition to enhance disease control in conventional and organic cropping systems.

“…Two-spray programmes commonly give larger responses than a single spraying (Jordan & Stinchcombe 1986;Cunningham & Dunne 1991). Leaf diseases and responses to fungicide sprays can also be modified by the timing of nitrogen applications (Jordan et al 1985;Jordan & Stinchcombe 1986;Jordan et al 1989) and it has been suggested that if the timing of nitrogen applications in spring is optimal, only a single fungicide spray is necessary to obtain economic control of leaf diseases in winter barley. Thus in an experiment in 1987 on winter barley (cv.…”

SUMMARYThe effects of varying the timing of nitrogen application and the frequency of fungicide sprays on the incidence of foliar disease and on the grain yield of winter barley (cv. Panda) were investigated at two sites in Ireland over three years, 1986–88. Nitrogen application timing had little effect on the amount of foliar necrosis due to disease but delaying application of all the nitrogen until April significantly reduced grain yields in two of the three years when compared with standard split dressings in March and April. The reductions in yield reflected small differences in 1000-grain weight.The number of fungicide sprays applied had significant effects on the amount of foliar necrosis and on grain yields. One-spray and two-spray programmes increased average yield by 16 and 32%, respectively. The yield increases were attributable to more ears/m2 and larger grains (greater 1000-grain weight). Fungicides also delayed the onset and significantly reduced the amount of brackling. Delaying nitrogen application in the spring did not decrease the number of fungicide sprays required to achieve maximum yield.
