摘要

锈病，由尾尾尿霉菌引起。Unger，在豆类(Phaseolus vulgaris)生产中具有重要的经济意义，特别是在热带地区，产量损失为18-100% (Vargas, 1980;Bokosi, 1996)。在东非，这种疾病一直是限制生产的一个主要因素，因为它可能在作物营养阶段的任何时候达到流行水平(Marcatney, 1966;Nderitu, 2001)。如果植物在开花前和开花发育阶段受到影响，可能导致作物歉收(Vargas, 1980;Omunyin等等。, 1984)。

Chemical Control Studies and Resistance to Bean Rust in Bean Germplasm

Rust, caused by Uromyces appendiculatus (Pers.) Unger, is of economic importance in bean (Phaseolus vulgaris) production particularly in the tropics with yield losses of 18-100% (Vargas, 1980; Bokosi, 1996). In East Africa, the disease has been a major factor limiting production because it may reach epidemic levels at any time during the vegetative stage of the crop (Marcatney, 1966; Nderitu, 2001). Crop failure may result particularly if plants are affected during the pre-flowering and flowering stages of development (Vargas, 1980; Omunyin etal., 1984).
