'This is the reason that the white gold is under severe attack of the whitefly, thrips and pink bollworm and is turning into black due to subsequent development of sooty mold
on affected leaves.
Black, sooty mold
is a fungus that grows on the honeydew.
* Massive honeydew build-up under plants, sometimes with black sooty mold
The goals are to determine the feeding damage to the vine, long-term damage, amount of yield reduction and the impact of sooty mold
(which can occur on the honeydew secreted by the insects as they feed) on the vines.
They tend to be prone to sooty mold
, scale insect and woolly aphid.
Mahogany seedlings showed deformation of the stem and the apical bud and the presence of sooty mold
fungi due to the large amount of honeydew excreted by the insect (Fig.
Whiteflies also produce large amounts of sticky, sugary honeydew, which in turn is colonized by black sooty mold
, reducing the attractiveness and marketability of whitefly-infested crops.
It also causes indirect damage by its excretion, which favors the development of sooty mold
(Capnodium sp.) that completely coats the leaf, resulting in reduction of photosynthesis and impairing plant respiration (Oliveira et al., 2001).
These pests produce sticky secretions called "honeydew" that drip from the leaves, appearing as though your crape myrtle is "crying." These secretions stimulate the growth of sooty mold
, an unsightly black coating on leaves.
Additionally a visual percentage of leaf canopy coverage by the sooty mold
fungus caused by Capnodium sp.
This sticky substance is a medium for the growth of sooty mold
fungi and can attract ants, flies and other insects.
