Stable S-(+)-abscisic acid (S-ABA) non-aqueous liquid solutions are generally achieved without the use of an effective amount of an antioxidant and/or an ultraviolet absorber to S-(+)-abscisic acid. In a preferred embodiment, the stable S-(+)-abscisic acid (S-ABA) nonaqueous liquid solutions includes at least one organic solvent, such as at least one polyethylene glycol, at least one glycol, and/or at least one lactamide and/or at least one pentanoate.

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.

The present invention belongs to the field of biotechnology, in particular to a multivalent fusion protein AB-NAC-189, method for producing the same, and uses thereof. The protein AB-NAC-189 is a fusion of a polypeptide segment AB, nascent polypeptide-associated complex (NAC), and a protein 189 corresponding to amino acids 1-189 from the N-terminal of protein HarpinEa. The fusion has the properties of a multivalent plant immune protein, thus it can effectively stimulate the hypersensitive response of tobacco leaves and has good thermal stability. While stimulating the immune response of plants, it can also improve the disease resistance of plants and promote plant growth. The AB-NAC-189 multivalent vaccine shows higher activity per unit concentration, and greater ability to promote growth of wheat and tobacco; meanwhile it can significantly promote chlorophyll synthesis in Goji berry, thereby improving the yield and quality of Goji berries.

The present invention relates to active compound combinations, in particular within a fungicide composition, which comprise as compound (a) one or more fatty acids or derivatives thereof selected from unsaturated and saturated C.sub.12-24 fatty acids, salts thereof, esters thereof or mixtures of any of the foregoing and as compound (b) at least one further agent active against at least one plant pathogen and/or active in plant growth promotion. Moreover, the invention relates to fungicide and/or plant health compositions comprising such compound combination and to the use of the compound combinations and the fungicide compositions as biologically active agent, especially for control of phytopathogenic fungi in crop protection and in the protection of industrial materials and as plant growth regulators and for improving plant health.
