The occurrence of garden strawberry grey rot in 2020–2021 over the period of harvesting amounted to, on average, 13,9 % and 21,2 % respectively. A four time application of Serenade ASO, SC biological preparation (Bacillus amyloliquefaciens, strain QST 713) in a dose of 6,0–8,0 l/ha before harvesting held effectively the spread of the disease. In the field experiment on small plots the reduction of the number of infected berries amounted to from 55,4 % to 63,3 %, which affected the yield (up to 37,5 dt/ha). |
