    Abstract: Abstract The present invention relates to novel isolated bacterial strains, which are members of the genus Paenbaci//us, originally isolated from soil and showing antagonistic activity 5 against a broad range of pathogens and being capable of producing antimicrobial metabo lites. It was found that the strains Lu16774 and Lu17007 belong to a novel subspecies named Paenibaci//uspo/ymyxa ssp. plantarum while the strain Lu17015 belongs to a novel species which is proposed to be Paenbac//us epphyticus. The present invention also relates to microbial pesticide compositions comprising at 10 least one of such novel bacterial strains, whole culture broth or a cell-free extract or a frac tion thereof or at least one metabolite thereof, and/or a mutant of at least one of said novel bacterial strains having all the identifying characteristics of the respective bacterial strain or whole culture broth, cell-free extract, fraction and/or metabolite of the mutant thereof showing antagonistic activity against plant pathogens. The present invention also relates to 15 a method of controlling or suppressing plant pathogens or preventing plant pathogen infec tions by applying such composition. The present invention also relates to novel fusaricidin type compounds which are metabolites produced by the strains of the present invention. 18398083_1 (GHMatters) P42612AU01

    Abstract: A use of a graft copolymer obtained by free-radical polymerization of a monomer mixture comprising N-vinyllactam, vinyl ester, and a polyether for increasing the activity of a pesticide is disclosed. A composition comprising a pesticide and a graft copolymer obtained by free-radical polymerization of a monomer mixture comprising i) 30 to 80% by weight of N-vinylpyrrolidone, N-vinylcaprolactam or mixtures thereof, ii) 10 to 50% by weight of vinyl acetate, and iii) 10 to 50% by weight of a polyether is also disclosed. Furthermore a method for preparing said composition by mixing the pesticide and the graft copolymer and a method for controlling phytopathogenic fungi and/or undesired plant growth and/or undesired attack by insects or mites and/or for regulating the growth of plants are also disclosed.
