    摘要: A Bacillus altitudinis ST15 antagonizing Xanthomonas oryzae and use thereof, the Bacillus altitudinis ST15 was deposited in China General Microbiological Culture Collection Center on Jun. 28, 2020 and has the deposit number of CGMCC No. 20156. The Bacillus altitudinis has a relatively high antagonistic activity to Xanthomonas oryzae pv. oryzae and Xanthomonas oryzae pv. oryzicola, can promote growth of rice and improve a drought resistance of a rice seedling, and has a relatively strong tolerance to common chemical microbicides for controlling bacterial diseases of rice. A bacterial suspension or a biocontrol inoculant prepared from this strain has a relatively high biocontrol effect on bacterial blight of rice and bacterial leaf streak of rice, can replace or reduce chemical pesticides, improves safety of food and ecological environment, and has relatively high economic and social benefits.

    摘要: Disclosed is a plant disease control composition for soaking virus-infected plant seeds. The plant disease control composition is a composition including nitrogen, phosphate, potassium oxide, manganese, molybdenum, zinc, boron, copper, and a surfactant and characterized by exhibiting an effect on the diseases of cucurbitaceae or solanaceae crops. A plant disease control method for seed soaking involves soaking seeds in a plant disease control composition including nitrogen (N), phosphoric anhydride (P2O5), potassium oxide (K2O), boron (B), manganese (Mn), molybdenum (Mo), zinc (Zn), copper (Cu), and a surfactant to control plant diseases.
