Modelling coffee leaf rust dynamics to control its spread

Coffee leaf rust (CLR) is one of the main diseases that affect coffee plantations worldwide. It caused by fungus Hemileia vastatrix . Damages induce severe yield losses (up to 70%). Its control mainly relies on cultural practices and fungicides, latter having harmful ecological impact important cost. Our goal understand propagation this in order propose a biocontrol solution, based mycoparasite inhibits H. reproduction. We develop explore spatio-temporal model describes CLR plantation during rainy dry seasons. show existence solution prove there exists two threshold parameters, basic reproduction numbers, determine stability equilibria for season subsystems. To illustrate these theoretical results, numerical simulations are performed, using non-standard finite method integrate pest model. also numerically investigate impact. its efficiency ensure eradication.
