BOTRFA
Reported in many countries but only widespread in Egypt and the United Kingdom
5 Known Hosts
Glycine max
soybean
No
BOTRFA-7, CABICPC
There is no evidence that seed is a pathway for this pathogen in this crop. This is a minor pathogen of soybean.
Lens culinaris
lentil
Yes
BOTRFA-9, CABICPC
Though not as common as Botrytis cinerea on lentils, seed transmission has been established on this crop.
Agar incubation, Blotter paper
These methods have not been standardized or validated. Blotter paper was used in research Vicia faba and may be applied to this crop.
BOTRFA-10, BOTRFA-9
Seed treatments, Benomy, Carboxin, Chlorothalonil, Thiobendazole
These treatments were described for Vicia faba.

Vicia faba
faba bean
Yes
BOTFRA-2, BOTFRA-3, BOTFRA-4, BOTFRA-5, BOTRFA-10, BOTRFA-6, BOTRFA-8, CABICPC
Survives on seeds as conidia, mycelium or sclerotia.
Yes
Blotter
This method has not been standardized or validated. Used in research only.
BOTRFA-10
Chemical, Cultural
Foliar-applied fungicide may be applied at regular intervals during the growing season. High humidity should be avoided, choose optimum seed rates, avoid high planting densities and avoid growing in oversheltered areas.
