Pseudocercospora abelmoschi treatment
I have a British friend living in The Gambia, West Africa .. he is an avid gardener and in his retirement is creating a lovely Tropical garden.
However he is having trouble with black mould on his Hibiscus plants .. which I assume to be pseudocercospora abelmoschi after researching it on the Internet.
After much searching, their is plenty of information on classifying this particular mould, but virtually none on methods of treatment.
Can any of you suggest appropriate measures he can take to eradicate and prevent re-infection of this mould please ? Bearing in mind that he has little or no access to modern anti-fungal treatments, being in the depths of the African bush.
Any old fashioned ( pre chemical dominance ) treatments you could suggest please ?
Thank you in advance for any help you can offer ....
