Leaf spots reduce the surface area available on leaves for photosynthesis and so can result in smaller growth and yield of plants. Weakened plants may produce lesser fruit. Virus caused leaf spots reduces chlorophyll in the leaves, resulting in less photosynthetic activity.
A 1987 study found evidence of a possible biocontrol strategy for bacterial wilt of turf grass. The researchers found that antiserum to Pseudomonas fluorescens or Erwinia herbicola from hosts which have survived infections by the corresponding pathogens is capable of reducing wilt symptoms in turf grass caused by Xanthomonas translucens. The ...
Wilt diseases in woody plants tend to fall into two major categories, those that start with the branches and those that start with the roots. Those that start with the branches most often start with pathogens that feed on the leaves or bark, those that start with the roots start with wounding or direct entry by the pathogen into the roots, some ...

Forsythia are deciduous shrubs typically growing to a height of 1–3 m (3 ft 3 in – 9 ft 10 in) and, rarely, up to 6 m (20 ft) with rough grey-brown bark. The leaves are borne oppositely and are usually simple, though sometimes trifoliate with a basal pair of small leaflets; they range between 2 and 10 cm (0.79 and 3.94 in) in length and, rarely, up to 15 cm (5.9 in), with a margin that is ...
Too many leaves can kill grass. Mulch mowing can incorporate about six inches of leaves back into the soil, after which the leaves must be removed to prevent shading and smothering the lawn over ...
Bacterial leaf scorch (commonly abbreviated BLS, also called bacterial leaf spot) is a disease state affecting many crops, caused mainly by the xylem-plugging bacterium Xylella fastidiosa. [1] It can be mistaken for ordinary leaf scorch caused by cultural practices such as over-fertilization.
5. Low Humidity. Light brown spots scattered across fiddle leaf fig leaves can be caused by dry air. If the brown spots in question have a pox-like look instead of being in a single area of the ...
