Chocolate spot disease caused by Botrytis fabae manifests itself as small red-brown spots on leaves, stems and flowers of broad bean plants. These enlarge and develop a grey, dead centre with a reddish-brown margin. Spores form on the dead tissue and spread the infection to other plants. In severe infections leaves and flowers may fall and ...

Curly top of common bean caused by Beet curly top virus. Curly top [1] is a viral disease that affects many crops. This disease causes plants to become smaller in size, have shriveled petals and leaves, and are twisted and pulled out of shape.
The host-specific characteristic of many leaf spot pathogens makes diversity in plant species a way to reduce and regulate leaf spot pathogen infection levels within plant populations. [ 18 ] Prevention of leaf spot disease includes variety selection, crop rotations, plant hygiene and fungicide use for seeds and foliage. [ 19 ]
BPMV is the viral pathogen that causes the disease Bean Pod Mottle in soybeans and other legumes such as snap peas.BPMV is a species in the plant pathogenic virus family Comoviridae, and genus Comovirus is characterized by icosahedral symmetry, non-enveloped, having two single stranded positive-sense RNAs (RNA-1 and RNA-2) separately encapsulated in isomeric particles, and are between 28 and ...
Sword beans are relatively resistant to diseases and pests. [7] A major disease affecting sword beans is Anthracnose, which is caused by fungal pathogens of Colletotrichum species. Severe lesions can be found both on the stem and leaves. [9] Research has also shown that Bean Common Mosaic Virus (BCMV) can infect the sword bean. Previously it ...
