Humidity Control for
PATHOGEN
PREVENTION
in a Greenhouse
or Indoor Garden
Pathogenic fungi can be very destructive to an in-
door garden or greenhouse. Much like pest insects,
pathogenic fungi are capable, under the right cir-
cumstances, of quickly destroying an otherwise
flourishing crop. To effectively defend a garden
against such an attack, indoor horticulturists and
greenhouse hobbyists should know how to pre-
vent, positively identify, and treat the most common
fungi pathogens. As with most garden disturbances,
prevention is the most powerful defense. However,
chances are good that even the most diligent grow-
ers will experience a hiccup or two when cultivat-
ing plants indoors or in a greenhouse. The two
most common fungi pathogens to plague indoor
horticulturists and/or greenhouse hobbyists are
powdery mildew and botrytis (fruit or flower rot).
