Abstract
In the 1980s, coffee production in Kenya peaked at an average of 1.7 million bags annually. Since then,
this production has declined to the current output of below 0.9 million bags annually. Coffee berry disease
(CBD) and Coffee leaf rust (CLR) are some of the causes of this decline. This is due to insufficient knowledge
of optimal control strategies for CBD and CLR co-infection. In this research, we derive a system of ODEs from
the mathematical model for co-infection of CBD and CLR with control strategies to perform optimal control
analysis. An optimal control problem is formulated and solved using Pontryagin’s maximum principle. The
outcomes of the model’s numerical simulations indicate that combining all interventions is the best strategy
for slowing the spread of the CBD-CLR co-infection.
