Begonias
are among America’s favorite shade plants, with lush leaves and splashy
blossoms in a multitude of colors. Generally, they are healthy, low-care
plants, but they are susceptible to a few fungal diseases like botrytis of
begonia. Begonias with botrytis is a serious disease that can endanger the life
of the plant. Keep reading for information about treating begonia botrytis, as
well as tips about how to avoid it.
About Begonias with Botrytis
Botrytis of begonia is also known as botrytis
blight. It is caused by the fungus Botrytis
cinerea and is most likely to appear when temperatures dip and moisture
levels rise.
Begonias with botrytis blight decline rapidly. Tan spots and
sometimes water-soaked lesions appear on the foliage and stems of the plant.
Cuttings rot at the stem. Established begonia plants rot as well, starting in
the crown. Look for dusty gray fungal growth on infected tissue.
The Botrytis cinerea
fungus lives in plant debris and multiples quickly, especially in cool, high
moisture conditions. It feeds on wilting flowers and senescent leaves, and from
there, attacks healthy leaves.
But begonias with botrytis blight are not the only victims
of the fungus. It can also infect other ornamental plants including:
Begonia Botrytis Treatment
Treating begonia botrytis begins with taking steps to
prevent it from attacking your plants. While it won’t help your begonias with
botrytis, it will prevent the disease from passing to other begonia plants.
Cultural control starts with removing and destroying all
dead, dying or wilting plant parts, including dying flowers and foliage. These
dying plant parts attract the fungus, and removing them from the begonia and
potting soil surface is a very important step.
In addition, it helps keep the fungus away if you increase
air flow around the begonias. Don’t get water on the leaves as you are watering
and make an attempt to keep the leaves dry.
Fortunately for begonias with botrytis, there are chemical
controls that can be used to help infected plants. Use a fungicide that is
appropriate for begonias every week or so. Alternate fungicides to prevent
fungi from building up resistance.
You can also use biological control as begonia botrytis
treatment. Botrytis of begonia was reduced when Trichoderma harzianum 382 was
added into a sphagnum peat potting media.
