Blast and Bacterial Diseases of Some Seed-dressed Rice Varieties in Yogyakarta.

Abstract Pyricularia grisea (blast disease) and bacterial diseases resulted rice yield loss. Tolerant varieties seed-dressing are expected reduces the disease. This research was aimed to define effect of tolerant seed - dressing incidence blast diseases. Research conducted at endemic area in Yogyakarta Indonesia from November 2021 March 2022. The experiment designed randomized block with 2 factors 4 replications. Factor 1 variety: Inpari 32 HDB, 45 Dirgahayu 48 Blas as variety Sunggal common variety. treatment: Pseudomonas fluorencens solutions, consortia antagonist fungi bacterium, fungicide Trisiklazol 225 g l −1 Azoksistrobin 75 . Results showed that significantly reduced BLB. highest were found Sunggal, while not Blas. Meanwhile, low level 3 varieties. Bacterial disease this BLB (Bacterial Leaf Blight), BRS Red Stripe) BLS Streak). Result also treatment did affect reduction At other site, (10.18 ton ha ) obtained HDB which treated bacterium. Hence, tested promising be established agro ecosystem irrigated Indonesia.
