Abstract:
The present invention relates to a method for applying an aqueous, pesticide-containing dispersion of a polyurethane which is a reaction product of at least one polyol (A) and at least one polyisocyanate (B) onto plants or plant parts. The invention also relates to an aqueous, pesticide-containing dispersion of a polyurethane which is a reaction product of at least one polyol (A) and at least one polyisocyanate (B). The invention further relates to the use of the dispersion for controlling phytopathogenic fungi and/or undesired plant growth and/or undesired insect or mite infestation and/or for regulating the growth of plants by letting the dispersion act on the respective pests, their biotope and/or the plants and plant parts to be protected from the respective pests, the soil and/or on undesired plants and/or useful plants and/or their biotope.
Abstract:
The present invention encompasses aqueous dispersions comprising a nanoparticulate formulation of active crop protection ingredients, in which the nanoparticles have core-shell structures with a mean particle diameter of 0.05 to 2.0 µm and the active crop protection ingredient is present in the core in X-ray-amorphous form together with one or more polymers, and the shell consists of a stabilized envelope matrix preparable by a process which is characterized in that (a) a solution of the active crop protection ingredient in a water-miscible organic solvent is prepared, (b) the solution obtained in step (a) is mixed with the core polymer or a solution of the core polymer in a water-miscible organic solvent, the polymer being insoluble or only partly soluble in water or aqueous solutions or water-solvent mixtures; and (c) the mixture resulting from (b) is contacted with an aqueous solution comprising components of the envelope matrix.
Abstract:
The present invention relates to novel isolated bacterial strains, which are members of the genus Paenibacillus, originally isolated from soil and showing antagonistic activity against a broad range of pathogens and being capable of producing antimicrobial metabolites. It was found that the strains Lu16774 and Lu17007 belong to a novel subspecies named Paenibacillus polymyxa ssp. plantarum while the strain Lu17015 belongs to a novel species which is proposed to be Paenibacillus epiphyticus. The present invention also relates to microbial pesticide compositions comprising at least one of such novel bacterial strains, whole culture broth or a cell-free extract or a fraction 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 a method of controlling or suppressing plant pathogens or preventing plant pathogen infections 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.
Abstract:
The present invention relates to a method of applying an aqueous, pesticide-comprising dispersion of a polyurethane which is composed of diisocyanates (a) and diols (b), to plants or plant parts. Furthermore, the invention relates to an aqueous, pesticide-comprising dispersion of a polyurethane which is composed of diisocyanates (a) and diols (b). It furthermore relates to the use of the dispersion for controlling phytopathogenic fungi and/or undesired plant growth and/or undesired attack by insect or mites and/or for regulating the growth of plants, by allowing the dispersion to act on the respective pests, their environment and/or the plants to be protected from the respective pest, on plant parts, on the soil and/or on undesired plants and/or on the useful plants and/or their environment.
Abstract:
The present invention includes aqueous dispersions including a nanoparticulate formulation of crop protection agents in which the nanoparticles have core-shell structures with an average particle diameter of from 0.05 to 2.0 µm, and the crop protection agent is present in the core in X-ray amorphous form together with one or more polymers, where the polymer is insoluble or only partly soluble in water or aqueous solutions or water-solvent mixtures, and the shell consists of a stabilizing enveloping matrix which can be produced by a method which is characterized in that (a) a solution of the crop protection agent in a water-immiscible organic solvent is prepared, (b) the core polymer is dissolved in a water-immiscible organic solvent; and (c) the mixture resulting from (a) and (b) is emulsified with an aqueous solution including components of the enveloping matrix by injecting the appropriate solutions into a mixing chamber, and removing the organic solvent after emulsification.
