The main diseases that attack plants are those caused by
various fungi. Many fungi are harmless or even beneficial in the garden,
but there are several fungus types that can cause diseases ranging from
wilt to basic rots or just potentially lethal leaf discolorations.
One of the most common problems on specific plants is
that of Rose Black Spot - a fungus. It is different, though similar to
the Black Spot that materialises on Acers. However, the treatment is
broadly similar.
Plant diseases are very difficult to positively
identify, as there are many diseases that cause the same symptoms - as
in the Rose and Acer black spot diseases. The good news is, that most
'similar' diseases can be treated in general terms. Absolute positive
identification is not always necessary - unless of course you are rather
deep into plant pathology! Theses pages are not for you!
'Damping off' of seedlings in the seed tray is caused
by several different fungal pathogens. They can all be thwarted with the
same good husbandry, or controlled with the same broad spectrum
fungicides. There are only a handful of worthwhile fungicides on the
market. A collection of two or three will normally deal with any fungal
infection you are pestered with. Of that, more later.
