Spraying hydroponic lettuce roots with a suspension concentrate formulation of <i>Bacillus velezensis</i> to suppress root rot disease and promote plant growth
AbstractBacillus velezensis was prepared as a suspension concentrate (SC) and sprayed on to the roots of 1monthold Lactuca sativa grown in a hydroponic system In the first experiment using Lactuca sativa (var Red Coral) with root rot symptoms a 1 blank with no cells a 1 SC (1013 CFU/ml) and 1 fresh bacterial cells (FC) (1014 CFU/ml) reduced the percentage of root tips colonized by the pathogen and increased the fresh shoot weight compared to plants that were not sprayed In the second experiment with L sativa (var Green Oak) using healthylooking roots a 1 blank 10 SC (1013 CFU/ml) and 1 FC of the bacterium (1014 CFU/ml) reduced the percentage of root tips colonized by Pythium sp The SC and FC of the bacterium increased the fresh shoot weight while the blank the SC and the FC of the bacterium increased the dried weight of the shoot
