Zusammenfassung:PROBLEM TO BE SOLVED: To obtain a control agent for rice plant damping-off containing microorganism, Pseudomonas gladioli. SOLUTION: This rice plant damping-off control agent contains Pseudomonas gladioli (CAB-03 strain) and Pseudomonas gladioli (CAB-04 strain) as effective components. To control damping-off of rice plant seedlings, the bacterial strains are added to a dipping solution of rice seeds during rice seed dipping, or rice seeds after dipping are dipped in a suspension of the bacteria before seeding. The amount of bacteria in the dipping solution or the suspension is >=10 cells/ml. In case of using as a preparation obtained by adding or suspending the bacteria, the bacterial concentration is 10 -10 cells/ml. This control agent exhibits a strong onset-suppressing action on 3 important diseases consisting of seed and seedling rot caused by rice grain not bacteria, damping-off and useless unproductive growth disease induced by gibberells fujikuroi and is capable of controlling these 3 diseases at the same time and has no environmental pollution by the agrochemical.
