Didymella rabiei,
Names
The specific epithet rabiei refers to rabbia del cece or 'rabies of chickpea', a name for the disease.[4][5]
The disease is also referred to as ascochyta blight but there are other fungal species that cause diseases in other
Signs and symptoms
Once ascochyta blight has infected a healthy chickpea plant, it will start to develop lesions on all aerial plant parts. If a seed pod becomes infected, it may initially be asymptomatic, but will eventually develop dark lesions on the surface of the seed coats.[citation needed]
Description
D. rabiei has a spherical punctiform and membranous pyrenium, at first lutescent then opening to a rounded black ostiole.[5] It has numerous elliptical and hyaline spores or varying size.[5] The fungus survives within the infected crop debris from the previous growing season. It requires the infected debris, because it does not produce resting spores that allow it to survive in the soil during the winter. When surviving in crop debris, it typically lasts longer if exposed to drier conditions. When both compatible mating types of the fungus are present, it is able to develop a pseudothecia that produces airborne spores. These airborne spores play a major role in the dispersal of the pathogen. [7]
Hosts
D. rabiei is known for infecting cultivated annual chickpea (
Other host species include:
- dog fennel (Anthemis cotula)[1]
- alfalfa (Medicago sativa)[8]
- pea (
- Berseem clover (Trifolium alexandrinum)[8]
- wheat (Triticum aestivum)[1]
- faba bean (Vicia faba)[1]
- hairy tare (Vicia hirsuta)[11]
- cowpea (Vigna unguiculata)[8]
Proper management practices
The most important way to protect susceptible crops from this pathogen is to use resistant cultivars when planting. However, this disease has multiple mating types, and may lead to pathogen resistance if the same cultivars are repeatedly used. To add to this, there are a number of cultural practices that can help reduce the vigor of D. rabiei. These include, but are not limited to: using certified disease free seed, rotation to new crops every 2 or 3 years, and planting in wide rows with adequate spacing. [7]
