苜蓿锈病是威胁苜蓿生产的最主要病害之一。

Alfalfa rust is one of the most common and serious disease on alfalfa , and threatening the product of alfalfa .

在田间调查苜蓿锈病病情的基础上，分析了病情指数与产量损失率之间的线性关系，并据此建立了苜蓿锈病防治的经济阈值。

This Paper Was based on a field investigation of alfalfa ( Medicago Satival ) diseases . Linear relationships between the fresh matter yield and disease index were established by the coefficient analysis and a model of economic threshold for the disease control was developed .
