In-field proximal sensing of septoria tritici blotch, stripe rust and brown rust in winter wheat by means of reflectance and textural features from multispectral imagery

, 2020
During its growth, winter wheat (Triticum aestivum L.) can be impacted by multiple stresses involving fungal diseases that are responsible for high yield losses.

Tomato Septoria Leaf Spot Necrotic and Chlorotic Regions Computational Assessment Using Artificial Bee Colony-Optimized Leaf Disease Index

IEEE Region 10 Conference, 2020
Visual inspection of plant health status and disease severity may yield subjective assessments due to error-prone sphere of colors and textures as affected by angular photosynthetic light source and the complexity of chlorosis.

Reemergence of Septoria Leaf Spot Caused by Septoria cannabis on Hemp in Kentucky

Plant Disease, 2021
Hemp reemerged in 2014 after being illegal for over 50 years and restricted for 90 years. Today, hemp is primarily grown for production of cannabidiol (CBD), with limited acreage dedicated to fiber. One of the most frequent and destructive leaf spot diseases of hemp cultivars grown for CBD is Septoria leaf spot.

Septoria species on Acacia

Transactions of the British Mycological Society, 1987
Septoria phyllodiorum and S. acaciae are redescribed and illustrated from type collections and the new species S. grampianensis, S. lamentana , and S. aureocorona are described and illustrated. A key to the five accepted Septoria species on Acacia is given.

Breeding Wheat for Resistance to Septoria nodorum and Septoria tritici

1990
Publisher Summary There are three recognized Septoria diseases of wheat, each characterized by its causal fungus. On a worldwide basis, the two most important are septoria nodorum blotch (SNB) and septoria tritici blotch (STB). The third, septoria avenae blotch, is found infrequently and is generally considered a minor disease.

SIMSEPT – ein neues Prognosemodell zum Auftreten von Septoria tritici und Septoria nodorum

Gesunde Pflanzen, 2003
SIMSEPT ist ein neues Simulationsmodell zur Vorhersage des Auftretens von Septoria tritici und Septoria nodorum in Winterweizen. Es wurde im Auftrag der Zentralstelle der Pflanzenschutzdienste fur Entscheidungshilfen und Programme (ZEPP) entwickelt und soll die Pflanzenschutzdienste der Bundeslander in ihrer operativen Arbeit (Warndienst) unterstutzen.

Field validation of TOMCAST modified to manage Septoria leaf spot on tomato in the central-west region of Brazil

, 2020
Septoria leaf spot, caused by Septoria lycopersici, is a devastating disease on tomato in Brazil. In order to rationalize the chemical control, we validated the TOMCAST system to manage Septoria leaf spot on fresh market tomato in the State of Goias ...

Cytology of Septoria leucanthemi

Transactions of the British Mycological Society, 1974
The distribution, process of division and behaviour of nuclei during conidiogenesis were investigated in Septoria leucanthemi Sacc. & Speg. by the HCl-Giemsa technique. Individual conidial cells were uninucleate and mature pigmented hyphal cells were multinucleate.
