Abstract
In model system measure are aimed against whole patogen complex. Time, in which is fungicid first apply is determine time, in which is really achieved, or specific threshold value is crossed by one or more patogens.
Primary and secondary treatment influence along threshold value, which has to be quantified, determinates the biological need of other procedures (successive application). Model conception is managed with following principles: fungicid selection is managed according to strictly determinatedoriginars of illnesses, application number depends on determinated patogens, their threshold value and evolutionary phase of plant.
Integrated system supposes freedom in used amount (must not be crossed legal dose). Argument against use of lowered amount can not be fear of resistance, because antiresistant strategy must be based on wide range of integrated procedures, including cultivars using with various resistance, rotation of material with various mechanism of effect, combination of effective mater
