Sharka is a disease affecting stone fruit trees. It is caused by the Plum pox virus (PPV),
with Myzus persicae being one of the most efficient aphid species in transmitting it within and among
Prunus orchards. Other agricultural management strategies are also responsible for the spread of
disease among trees, such as grafting and pruning. We present a mathematical model of impulsive
differential equations to represent the dynamics of Sharka disease in the tree and vector population.
We consider three transmission routes: grafting, pruning, and through aphid vectors. Grafting,
pruning, and vector control occur as pulses at specific instants. Within the model, human risk
perception towards disease influences these agricultural management strategies. Model results show
that grafting with infected biological material has a significant impact on the spread of the disease.
In addition, detecting infectious symptomatic and asymptomatic trees in the short term is critical
to reduce disease spread. Furthermore, vector control to prevent aphid movement between trees
is crucial for disease mitigation, as well as implementing awareness campaigns for Sharka disease
in agricultural communities that provide a long-term impact on responsible pruning, grafting, and
vector control.
