The present disclosure relates generally to herbicidal compositions and methods of use thereof, and more specifically to herbicidal compositions containing aspterric acid or a derivative thereof for use in inhibiting vegetative growth in plants.

It relates to compositions produced by microorganism cell cultures, including microorganism-free compositions as well as compositions comprising inactivated microorganisms. It also relates to methods for obtaining the compositions produced by microorganism cell cultures and to agricultural compositions comprising them. It also relates to the use of the compositions of the invention as plant growth promoting agents and to methods for promoting stimulatory activity on plants comprising administering to the plant with these compositions.

The present disclosure describes a DNA fragment mixture for the prevention or for the treatment of at least one pathogenic, parasitic, or infesting species of plants or of the environment, wherein the DNA mixture consists of random fragments of total DNA of at least one pathogenic, parasitic, or infesting species, and/or at least one phylogenetically similar species, against which the prevention and treatment are directed. Further, the disclosure describes a process and related system for improvement of the production/growth of microorganisms at high yield in bioreactors or photobioreactors, or of plants in different culture systems, where the nucleic acids of the organisms produced/grown by such a process are removed from the culture medium and the culture medium, deprived of these nucleic acid, is used again in the process.

Process for conferring a protection against a pathogen upon a plant by elicitation by an aqueous composition, the active agents of which are extracted from edible fungi (parasol mushroom, pleurotus, button mushroom). An alkaline extraction is carried out, then an enzymatic hydrolysis, to obtain a fraction less than 100 kDa. The process consists in spraying the aerial parts of the plant with the composition obtained in this way; this thereby acts to combat cryptogamic diseases of plants such as vines, fruit trees, vegetable crops and cereals.

The invention relates to methods for controlling mycotoxin production in field populations of heterothallic and homothallic filamentous fungi through application of biocontrol compositions comprising selected strains of the heterothallic and homothallic filamentous fungi, the selected strains having a lineage of low mycotoxin production or no mycotoxin production and having opposite mating types (heterothallic) or both mating types (homothallic) (e.g., MAT1-1, MATT-2).

The present invention relates to a method for manufacturing an organic fertilizer prepared using antagonistic microorganisms, fermentative microorganisms, synthetic microorganisms, and organic raw materials, and to an organic fertilizer manufactured by the manufacturing method. The present invention has the technical feature wherein a powder-type organic raw material characterized by being produced via a contaminant removal step, a sterilization step, a microorganism culture medium preparation step, and a microorganism additive solution preparation step are subjected to a mixing step, a fermentation step, and a drying step. The present invention is effective for soil improvement, crop growth, and disease and pest control. In addition, fertilizer produced through the technical solution contains primary metabolites, secondary metabolites, conjugated enzymes, antibiotics, bioactive substances and inducers, etc., and thus not only does not contaminate the soil, but is also effective for ecosystem restoration, and for increasing profits through the production of safe organic crops.
