秆锈病对部份冬麦地区,有严重威胁。虽然病害的流行频率不高,但在流行年份,减产十分严重。目前这些地区小麦能抗秆锈的品种很少,而优良抗锈品种的培育需要较长的时间,并且品种的抗锈性还会丧失。因此,药剂防治还是必要的。 现有药剂防治秆锈的潜力 经过各地多年试验,已经找到一些防治秆锈的有效药剂。有些药剂如氟矽酸钠、氟钡剂、氨基磺酸钙等,在病情严重时也能起一定的保产作用;但 Straw rust is a serious threat to some winter wheat areas. Although the prevalence of diseases is not high, in the popular year, production cuts are very serious. At present, wheat varieties resistant to stalk rust are few in these areas, while cultivation of fine rust resistant varieties takes a long time and the rust resistance of varieties is also lost. Therefore, drug control is still necessary. The potential of the existing medicament for controlling stalk rust has been tested for many years around the country and some effective medicaments for controlling stalk rust have been found.
