Silicon soil amendment as a complement to manage tan spot and fusarium head blight in wheat

Tan spot, caused by Pyrenophora tritici-repentis, and fusarium head blight (FHB), the Fusarium graminearum species complex, are among main wheat diseases worldwide. This 3-year field study evaluated effect of soil incorporation calcium silicate, a source silicon (Si), to manage tan spot FHB improve grain yield quality. The Si was compared on two cultivars contrasting in disease resistance associated with one or fungicide sprays. Calcium silicate fertilization increased concentration leaf spike tissues. increase tissues reduction severity both FHB, consequently quality wheat. conferred greater for than FHB. greatest control obtained moderately resistant cultivar grown amended (+Si) treated sprayings. On other hand, highest yield, under high pressure, +Si plants, regardless cultivar, results this show first time that complemented genetic treatments controlling Furthermore, indicate is useful as part integrated management these diseases.
