 # SeptoriaApiicolaModel
 
-This repository contains the implementation of the Septoria apiicola model.
+<img src="src/main/resources/images/septoriaapiicola.jpg" title="S. apiicola in celery (Photo: E. Fl&oslash;istad, NIBIO)"/>
+<p>This model is based on a calculation of how leaf wetness periods influence 
+infection of celery by <em>Septoria apiicola</em> in susceptible host plants.<p>
+<p>Forecasts of infection risk are given after a minimum of 12 consecutive hours 
+of leaf wetness. The wet periods are calculated from sensors placed 30 cm above 
+ground. If such a sensor is not available, data from leaf wetness sensors placed 
+2 m above ground are used.</p>
+<p>The model is developed in Michigan, USA and published by Lacy, 1994.</p> 
+<p>It is generally assumed that this model has additional relevance for Septoria petroselini in parsley.</p> 
+<h3>Warning interpretation</h3>
+<p><em>The following recommendations are provided for the Norwegian celery production.</em></p>
+<p>The model is a tool to decide when to start looking for initial disease 
+outbreaks. It is not considered accurate enough to provide reliable advice for 
+timing of fungicide applications under Norwegian conditions. </p>
+<p>If inoculum is present, infections are expected to develop 7-14 days after 
+the first infection risk periods (yellow or red warnings). It is recommended to 
+intensify field inspections after periods with risk warnings to detect early 
+infections of <em>Septoria apiicola</em>. </p>
+<ul>
+<li>Green: No risk of infection.</li> 
+<li>Yellow: Weather conditions favorable for infection risk. No known sources of 
+inoculum in the region.</li> 
+<li>Red: Risk of infection and infections of Septoria late blight has been 
+reported in the nearby region. Disease reports and field inspections are 
+performed in collaboration with advisors in the Norwegian Agricultural Advisory service.</li>
+</ul>
+<p>Graph legend: Blue bars indicate periods of at least 12 consecutive hours of 
+leaf wetness. Black bar indicate date of first field observation of Septoria late 
+blight.</p>
+<h3>Forecast season (Norway only)</h3>
+<p>In Norway this model is generally started June 1 and ends September 30. </p>
+<p>The model is running on all weather stations located in regions of commercial celery production.</p> 
+<h3>Model validation</h3>
+<h4>Norway</h4>
+<p>Validation of this model under Norwegian conditions is ongoing. The current 
+recommendation for this model is as a tool for timing of field inspections. </p>
+<p>Studies of weather conditions, spore production and infection events have been 
+carried out in field trials at Ås from 2012-2016. Preliminary results indicate a 
+good fit, although some adjustments could improve the model, particularly in 
+connection with rain events (Nordskog and Le, 2014). </p>
+<h4>Internationally</h4>
+<p>The model is developed in Michigan, USA and published by Lacy (1994)</p>
