种植抗绣品种是防治小麦锈病最有效最经济的办法。但是,目前适于各地种植的抗锈品种还很少,远远不能满足生产的需要,即使已经种植抗锈品种的地区,也往往由于品种本身的变化,或新的锈菌生理小种的出现而丧失抗病性。在一些还没有适当抗锈品种、或原有抗锈品种丧失抗病力的地区,在尚无新的抗病品种更替以前,一旦发生锈病,就需要采取其他措施,以求尽量减少绣病的为害。在药剂防治方面,几年来通过各地进行大量的科学实验和示范推广,有很多成功的事例。但是,药剂防治小麦锈病是一项相当复杂的技术,影响效果的因素很多,如使用不当,有时效果很低甚至无效,不 Planting resistant varieties is the most effective and economical way to control wheat rust. However, at present, rust-resistant varieties suitable for planting all over the world are few and far from being able to meet the needs of production. Even if areas where anti-rust varieties have been cultivated are often caused by changes in the varieties themselves or the emergence of new rusty races And loss of disease resistance. In some areas where there is no suitable anti-rust species or the original anti-rust varieties have lost their disease resistance, no rust-resistant ones will need to be taken before any new ones are replaced. Harmful. In the field of medicament control, there have been many successful examples in the past few years through a large number of scientific experiments and demonstration and promotion. However, the pharmaceutical control of wheat rust is a very complicated technology, many factors that affect the effect, such as improper use, sometimes ineffective or ineffective, not
