Winter triticale (Triticale) cv. Dinaro and winter rye (Secale cereale L.) cv. Dańkowskie Diament were grown in 2012 and 2013 in a field-plot experiment in Tomaszkowo near Olsztyn (NE Poland). The experiment consisted of 7 treatments: absolute control (without fertilizers or the growth stimulator), control-NPK fertilizer, NPK fertilizer + micronutrients applied alone or in combination (4 treatments), NPK fertilizer + Nano-Gro growth stimulator. The severity of disease symptoms on the leaves and stem-bases of triticale and rye was evaluated throughout the growing season. Symptoms of powdery mildew on the leaves of winter triticale and winter rye were noted only in the growing season of 2013, and disease severity remained at a low level. In the growing season of 2012, weather conditions were conducive to the spread of Septoria tritici blotch (STB) and brown rust on triticale (the highest values of infection index were 41.6 and 23.8%, respectively), and scald and brown rust on rye (29.0 and 38.1%, respectively). Foliar application of micronutrients influenced the rates of infections caused by Zymoseptoria tritici and Puccinia recondita f. sp. tritici on triticale leaves. Symptoms of eyespot and Fusarium foot and root rot were noted on the stem-bases of both cereal species, whereas symptoms of take-all disease and sharp eyespot were observed sporadically. Significant differences were found between treatments in the severity of infections caused by Gaeumannomyces graminis on the stem-bases of triticale, and by Tapesia spp. and Rhizoctonia spp. on the stem-bases of rye.

叶面肥和微量元素对冬小麦(x Triticosecale Witmm。)和黑麦(Secale graine L.)叶和茎基病发病率和严重性的影响

冬小麦(Triticale)简历。迪纳罗(Dinaro)和冬黑麦(Secale谷物 L.)简历 DańkowskieDiament于2012年和2013年在田纳西州奥尔什丁附近的Tomaszkowo(波兰东北)进行了田间试验。该实验由7种处理组成:绝对对照(不使用肥料或生长刺激剂),对照-NPK肥料,NPK肥料+单独或组合施用的微量营养素(4种处理),NPK肥料+纳米-Gro生长刺激剂。在整个生长季节中,对黑小麦和黑麦叶和茎基部的疾病症状的严重程度进行了评估。仅在2013年的生长季节才注意到冬小麦和黑麦叶片上的白粉病症状,而疾病严重程度仍处于较低水平。在2012年的生长季节,天气条件有利于小麦的传播黑小麦上有斑点(STB)和棕锈病(最高感染指数分别为41.6和23.8%),黑麦上有烫伤和棕锈病(分别为29.0和38.1%)。微量营养素的叶面喷施的影响所造成的感染的发生率Zymoseptoria小麦锈菌 F。sp 。小麦在小麦的叶子。在这两种谷物的茎干上都发现了眼斑和镰刀菌足和根腐病的症状,而零星地观察到全食性疾病和尖锐的眼斑的症状。引起感染的严重程度治疗之间发现显著差异小麦全蚀病菌对小黑麦的干基地,并通过Tapesia属。和根瘤菌属 在黑麦的茎基上。
