“…In their study and the other studies cited, however, the actual absorption of N in the crop was not measured. The present study, although with a different timing of N application from the study of Fauzi and Paulitz (1994), agrees with their suggestion because we found no significant effect of N application on FHB and mycotoxin accumulation, even with a significant increase in N (protein) content in grain or SPAD values of leaves. Lemmens et al (2004) reported a significant increase in FHB and DON with an increase in N input and suggested that N may increase FHB intensity by changing crop characteristics, notably by increasing crop density and altering the microclimate of the canopy.…”

“…Several previous studies have investigated the effect of N fertilization before heading, including base fertilization, on FHB in wheat, but the results were inconsistent. While some studies reported a significant increase in FHB intensity with increasing N input, at least in some environments (Heier et al 2005;Lemmens et al 2004;Martin et al 1991), others found little or no effect of N fertilization (Fauzi and Paulitz 1994;Oldenburg et al 2007;Schaafsma et al 2001;Subedi et al 2007;Teich and Hamilton 1985). Fauzi and Paulitz (1994) suggested that N would not change the inherent susceptibility of wheat ears to F. graminearum.…”

In terms of N application after heading, Iwabuchi et al (2007) observed a significant increase in FHB scores after N application at anthesis in Nishinokaori and Minaminokaori grown in the field under natural infection conditions.…”

Effect of nitrogen application at anthesis on Fusarium head blight and mycotoxin accumulation in breadmaking wheat in the western part of Japan

2008

In the western part of Japan, two wheat cultivars, Nishinokaori and Minaminokaori, are currently cultivated for breadmaking. Breadmaking wheat requires a higher protein content compared to the Japanese noodle wheat (the major type of wheat in Japan). This high protein level in the grain is obtained by top-dressing with nitrogen (N) near anthesis. Because such N applications may increase levels of Fusarium head blight (FHB) and consequent mycotoxin [deoxynivalenol (DON) and nivalenol (NIV)] accumulation in the grain, the effect of N application (0, 4, and 8 g/m 2 ) at anthesis on FHB and mycotoxin accumulation in Nishinokaori and Minaminokaori was tested in the greenhouse in 2004 and 2005 and in two fields in 2006. In the greenhouse, plants were spray inoculated at 3, 10, and 20 days after N treatment. In field experiments, colonized maize kernels, which generate ascospores during the testing season, served as inoculum. In all experiments for both cultivars, N application at anthesis significantly increased grain protein as expected, but had no significant effect on FHB and DON and NIV levels in grain. These results suggest that, at least in these cultivars, N can be applied close to anthesis without increasing the risk of FHB and mycotoxin (DON and NIV) accumulation.

“…Others found that head blight and mycotoxin levels were not affected by the level of applied nitrogen but were greater when the preceeding crop was maize (Teich and Hamilton, 1985). Both ethephon and chlormequat increased the incidence of spikelet infection, but only in treatments inoculated with infested corn (Fauzi and Paulitz, 1994). The objective of the present work was to determine the effect of growth regulators on plant architecture and microclimate, thus exerting an indirect influence on inoculum production and dispersal.…”

“…The flasks were agitated on a rotary shaker for 3 minutes and the suspension was dilution-plated on PDA amended with 100 μg/ml of chloramphenicol (Fauzi and Paulitz, 1994). The test established that approximately 70 μl suspension was deposited on each head.…”

A factorial field experiment was conducted on the demonstration plot of the Plateau Agricultural Development Project (PADP), Jos Plateau State in 1996 with three variables, nitrogen (0 or 80 kg/ha), growth regulator (none, ethephon or chlormequat) and inoculation (none, inoculation with macroconidia of Fusarium graminearum at anthesis or inoculation 1 week after anthesis). No head blight symptoms developed on plants in the field that year because of the dry conditions. Grain infection by Fusarium graminearum was assessed on a Fusarium selective medium. Nitrogen and growth regulators had no effect on grain infection. In 1997 and 1998, a 3 × 3 factorial experiment was conducted on the same site using the same growth regulator treatments and three inoculation treatments (no inoculation, heads inoculated with macroconidia or rows infested with Fusariumcolonized corn kernels that produced ascospores). The incidence of spikelet infection ranged from 2-4% in non-inoculated treatments to 7-25% in inoculated treatments. The incidence of seed infection ranged from 12-31% in non-inoculated treatments to 74-85% in inoculated treatments. Both growth regulators and inoculation treatments had significant effects (P=0.05) on spikelet infection and interacted with each other. These data suggest that growth regulators and nitrogen do not change the inherent susceptibility of wheat heads to F. graminearum, but dwarfed plants may be subject to higher inoculum doses because they are closer to ejected ascospores.
