(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.
(1) Phaeosphaeria
leaf spot 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.
[8] 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 diseases.
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.
niger) to expose the flowers and remove possible foliar diseases such as hellebore
