Disease-reducing effects of the 12-month formulations of Serratia nematodiphila CT-78 against rice bacterial leaf blight under field conditions

The aim of this study was to test for the disease-reducing effects of the 12-month formulations of the antagonistic Serratia nematodiphila CT-78 against rice bacterial leaf blight (Xanthomonas oryzae pv. oryzae) under field conditions. Three formulations composed of rice bran, rice husk and talc powder were tested. Experiments were carried out during the wet and dry seasons of 2019-2020. Rice seeds were treated with the formulations and pathogen inoculation was done at 45 days after sowing. The effects were shown and maitained until 15 days after pathogen inoculation by the formulations of rice bran, rice husk in both seasons.
