(2013), comparing the susceptibility of 'Rocha', 'Santa Maria' and 'Abate Fetel' pear to the entomosporiosis leaf spot
, considered that all cultivars are susceptible, however 'Santa Maria' obtained higher disease intensities, demonstrating that the genetic effect influences this characteristic.
The initial symptoms of disease involved small, oval or irregular, dark brown leaf spots
, later resulted into severe leaf blight covering entire leaf.
A combination of cultural and chemical measures is used to control Alternaria leaf spot
disease (Simone 1991).
Thus, the adoption of the SAD proposed in this paper to evaluate olive leaf spot
severity, can reduce the subjectivity of the estimates and provided better information for epidemiological studies on the Fusicladium oleagineum Olea europaea pathosystem under humid subtropical climate conditions.

could be detected accurately at the early stage using hyperspectral data.
megaterium, significantly decreased colony growth diameter (76.84-45.69%) of dracaena leaf spot
fungi as well as spore germination (48.80-23.20%) and length of germ tube (88.77-65.65%) of the germinated spores compared to untreated control.
 reported reduced Septoria leaf spot
disease by Septoria lycopersici in tomato-maize intercropping.
The phenotype data used in this research is 1100 barley entries with reaction of leaf spot
The stress is manifesting itself as leaf spot
, tar spot, leaf blotch and anthracnose disease infection in and on fallen leaves.
16, Tom Allen reported that frogeye leaf spot
is the most widely observed disease in fields.
Primulas can suffer from greenfly, grey mould and leaf spot
, but these are all rare.
