Induced plant immunity as a factor of an integrated winter wheat disease protection system

Abstract

The study deals with the system of integrated protection of winter wheat against phytopathogenic organisms. This includes the use of quaternary ammonium compounds combined with nanosilver in two stages: 1) pre-sowing treatment of seeds with the tank mixture of fungicide (difenoconazole + cyproconazole) and didecyldimethylammonium bromide enriched by nanosilver (0.15 %); 2) spraying of plants with immunity inducer at the end of the tillering – the beginning of booting. The leading role both in terms of protection and yield capacity belongs to early spring spraying with didecyldimethylammonium bromide enriched by nanosilver (0.3 %). This technique allowed obtaining the biological yield of winter wheat equal to 9.52 t/ha.
