How do I protect currants

Currants just like other cultivated plants are attacked by different pests and diseases. Below I present a list of the most important diseases and pests which attack currants, and chemicals which I use to eliminate them. I advice to apply presented chemicals changeable, because usement of the same detergent for a longer time decreases it's effectivness (pests and diseases immunize). Unfortuantelly mechanical harvesting damages currant shrubs what makes it more prone to pests and diseases (espacially ----- "Thomasiniana ribis"), against which plants need to be sprayed right after harvesting). If the harvester works on other plantations, disinfection is needed while travelling to different plantations because pests and diseases may be transfered. My farm is situated in the valley of "Wislok" river, so it runs a risk of spring light frosts which occur about the end of April and the begining of May. That's why during April when the temperature decrases below zero I spray plants with 1.5% solution of water and fertilizer what in some degree protects flowers from frozing.
