Lentil diseases

Abstract

Fungal diseases of lentils are the most important biological constraint to productivity. Ascochyta lentis (ascochyta blight) and Fusarium oxysporum f. sp. lentis (fusarium wilt) are the major fungal pathogens that can cause severe losses in most lentil growing regions of the world. Fungal diseases such as botrytis grey mould (Botrytis fabae and B. cinerea), rust (Uromyces viciae-fabae), stemphylium blight (Stemphylium botryosum), and anthracnose (Colletotrichum truncatum) are also important in some growing seasons in particular countries when environmental conditions are conducive for infection. Lentil plants can also be infected by a range of viruses but generally the affect on yield is not..
