Version of Record

In April 2017, seedlingblight was found on rice (Oryza sativa) in hosei university (Koganei city, Tokyo). A Fusarium sp. were frequently isolated from the diseased plants. Isolated fungi caused the disease after soil inoculation and reisolated from the diseased plants. The fungus was identified as Fusarium ploliferatum on the basis of morphological characteristics and results of the phylogenetic analysis based on TEF1-α, RPB1 and RPB2 gene sequences. This symptom was first record in japan. Compounds that provide more effective control against four rice seed borne diseases ("Bakanae" disease, Bacterial grain rot, Bacterial seedling rot and Bacterial brown stripe) by mixing with Talalomyces flavus wettable powder^(R)(TF WP) were screened. The mixture of TF WP, compound SXII and compound Tm-01 provide greater suppressions against these deseases than TF WP, SXII, Tm-01 alone or all possible combinations. Efficacy of this mixture was equal to Ipconazol copper flowable (IP F) against "Bakanae" disease and Bacterial seedling disease and more effective than IP F against Bacterial grain rot and Bacterial brown stripe.
