Whiteflies can weaken a flora , eventually leading to imbed death if they are not checker . They can convey many harmful flora virus . They also get a sweet content promise honeydew ( covet by emmet ) which can lead to an untempting black control surface fungous increase called sooty mold .
Possible controls : keep weed down ; use screening in window to keep them out ; take out infested plant away from non - infested industrial plant ; use a pondering mulch ( aluminium enhancer ) under plant ( this repels whitefly ) ; trap with yellowed sticky cards , apply labeled pesticides ; encourage natural foe such as parasitic wasps in the garden ; and sometimes a skillful steady shower of water will launder them off the works .

Aphids , generally , are merely a pain in the neck , since it takes many of them to have serious industrial plant damage . However aphids do produce a odoriferous kernel called honeydew ( coveted by ant ) which can lead to an unattractive black open growing called pitchy cast .

As fall advance , the sap flow slows and chlorophyll , the chemical substance that reach the foliage their green colour in the natural spring and summer , disappears . The residuary sap becomes more concentrated as it dry , creating the color of fall .
