leaf rust

In China, leaf rust occurs serious in North and Northeast regions, particularly in Southwest and Yangtze River Valleys.

在中国，小麦叶锈病尤以西南和长江流域一带发生最重，华北和东北部分麦区也发生严重。

Racial Identification of Wheat Stem Rust in 1984 in China and tne Application of Host Detached Leaf Culture Method

1984年全国小麦秆锈菌生理小种区系分析及寄主离体叶培养鉴定法的应用

The flowers and trees rust, downy mildew, black spot disease, leaf blight, branch blight disease, powdery mildew etc. were significantly controlled by this fungicide.

对花木锈病、霜霉病、黑斑病、叶枯病、枝枯病、白粉病、溃疡病等防效显著。

The same situation was on leaf blotch of wheat. However, the genotypes from Hebei did not show as much resistance to powdery mildew and leaf rust as European ones.

但是河北品种对小麦白粉病和锈病的兼抗性比欧洲品种低，而对小麦叶枯病的兼抗性较高。

The result showed that abnormal change value of leaf photosynthetic rate as a forecast index of rust incidence was representative and had higher fit degree, and this method is reliable and practical to a certain extend and is easi to be adopted.

结果表明：以单叶光合速率的异常变化的大小作为小麦条锈病发生程度的指标具有宏观模糊性，有一定的代表性，本方法简单易行，拟合率较高，有一定的可靠性和实用性。
