目前,防范小麦锈病的方式主要有两种,一种是使用抗锈病农药,二是针对Ug99开发具有免疫力的小麦新品种。麦锈病是不顾及政治僵局的全球旅客。借助自然界风的力量和人的携带,新型小麦锈病真菌Ug99(1999年在乌干达发现)很有可能从病源地中非穿越中东、中亚等地区,最终进入巴基斯坦、中国和印度。小麦占全球人口每天消费谷物产量的30%,而小麦锈病是其主要的病害之一。小麦锈病有条锈、叶锈和秆锈三种,其中秆锈病曾经是小麦的主要病害,可使小麦减产30%~50%,严 At present, there are mainly two ways to prevent wheat rust, one is the use of anti-rust pesticides, and the other is to develop new wheat varieties with immunity against Ug99. Wheat rust is a global traveler who disregards the political stalemate. With the power of the wind in the natural world and the carrying of human beings, the new wheat rust fungus Ug99 (discovered in Uganda in 1999) is likely to cross the Middle East and Central Asia and other regions from its source of disease and finally enter Pakistan, China and India. Wheat accounts for 30% of the world’s cereal consumption per day, and wheat rust is one of its major diseases. Wheat rust stripe rust, leaf rust and stalk rust three, of which stem rust was the main disease of wheat, can reduce wheat yield by 30% to 50%, strict
