“…Note that the function F_drug (t) models a simplified effect of a fungicide in practice. Despite this limitation, the results of the numerical solution of system (1) give acceptable results with the experimental curves of the development of the disease given in various sources [12][13][14]. The presented model can be implemented in decision support systems for agricultural farms.…”

“…Routine treatment of a plant with fungicides is a regular treatment that is carried out after a certain period of time (7-10 days). The main initial data are the results of monitoring the development of topsoil damage when exposed to late blight without treatment and treatment with Dithane (the active ingredient is mancozeb) in the UK in 2013 [12]. Processing dates for the observed period (from August 4 to September 3): August 8,16,23,30; September 6, 14, 21, 28.…”

Potato late blight is a harmful disease. Treatment of fields with fungicides is the main method of combating this phytopathology. The work presents a modified mathematical model “consumer - resource” - this is a system of partial differential equations, which contains a step function with the help of which fungicidal treatment can be successfully modeled. The system was solved numerically. Based on the modeling results, it is possible to successfully simulate the development of leaf damage during the growing season without and with fungicide treatment. Thus, knowing the duration of action of the drugs and assuming how intensively late blight will develop, it is possible to model different combinations of fungicides and spraying times. This circumstance can be successfully implemented into decision support systems for agricultural enterprises.
