小麦褐斑病和赤霉病是世界性的小麦主要病害之一。这项为期3年的田间研究评估了土壤掺入硅酸钙（硅的一种来源）对控制褐斑病和赤霉病以及提高粮食产量和品质的影响。比较了硅对两个抗病性差异较大的品种的抗病性的影响，并与一种或两种杀菌剂的喷洒相结合。施用硅酸钙提高了土壤和小麦叶、穗组织中硅的含量。小麦组织中硅含量的增加可减轻褐斑病和赤霉病的严重程度，从而提高小麦的品质和产量。硅对褐斑病病情严重程度的减轻作用大于赤霉病。最大的控制褐斑病和赤霉病得到了中等抗性品种生长在土壤中补充硅酸钙（+Si）和两种杀菌剂喷雾处理。另一方面，最高的粮食产量，在高的疾病压力下，获得+Si植物，无论品种，用两种杀菌剂喷雾剂处理。这项研究的结果首次表明，硅在土壤中的掺入补充了遗传抗性和杀菌剂处理在控制褐斑病和FHB的效果。此外，结果表明，硅酸钙施肥是有用的，作为这些小麦病害综合管理的一部分。
Tan spot, caused byPyrenophora tritici-repentis, and fusarium head blight (FHB), caused by theFusarium graminearumspecies complex, are among the main wheat diseases worldwide. This 3-year field study evaluated the effect of soil incorporation of calcium silicate, a source of silicon (Si), to manage tan spot and FHB and improve grain yield and quality. The effect of Si was compared on two cultivars contrasting in disease resistance and associated with one or two fungicide sprays. Calcium silicate fertilization increased the Si concentration in the soil and wheat leaf and spike tissues. The increase of Si concentration in wheat tissues was associated with reduction in the severity of both tan spot and FHB, consequently increased the quality and grain yield of wheat. The reduction of disease severity conferred by Si was greater for tan spot than FHB. The greatest control of tan spot and FHB was obtained with the moderately resistant cultivar grown in soil amended with calcium silicate (+Si) and treated with two fungicide sprayings. On the other hand, the highest grain yield, under high disease pressure, was obtained in +Si plants, regardless of the cultivar, treated with two fungicide sprays. The results of this study show for the first time that the incorporation of Si in the soil complemented the effect of genetic resistance and fungicide treatments in controlling both tan spot and FHB. Furthermore, results indicate that calcium silicate fertilization is useful as part of integrated management of these wheat diseases.
