Abstract: A mycological composite material is made by inoculating a substrate of fibrous material with an inoculum of mycelial tissue; rolling the inoculated substrate into a roll; and thereafter incubating the rolled inoculated substrate for a time sufficient for the mycelial tissue to grow hyphae that enmesh with the substrate to form a cohesive unified filamentous network with the rolled inoculated substrate being characterized in being flexible. The rolled inoculated substrate is subsequently processed by subjecting lengths of the roll to heat and pressure in molds to form rigid products.

Abstract: The present invention provides a method for making a consortium of fungi resistant to traces of carbamates contained in thiodicarb and to traces of synthetic pyrethroids contained in bifenthrin. During the course of this research, carried out over more than five years, the strains were subjected to a change in physical medium, adapting same to tolerate increasing concentrations of thiodicarb and bifenthrin. This compound enriches and increases the concentration of beneficial microorganisms, generating high-quality liquid biological fertilisers suitable for use in agricultural production, in land recovery and conservation, under the parameters established in sustainable organic farming, which seeks to conserve, recover and use nature or the environment without generating the least negative impact.
Abstract: A mycological biopolymer product consisting entirely of fungal mycelium is made by inoculating a nutritive substrate with a selected fungus in a sealed environment except for a void space, which space is subsequently filled with a network of undifferentiated fungal mycelium. The environmental conditions for producing the mycological biopolymer product, i.e. a high carbon dioxide (CO2) content (from 5% to 7% by volume) and an elevated temperature (from 85° F. to 95° F.), prevent full differentiation of the fungus into a mushroom. There are no stipe, cap, or spores produced. The biopolymer product grows into the void space of the tool, filling the space with an undifferentiated mycelium chitin-polymer, which is subsequently extracted from the substrate and dried.

Abstract: Remote access methods and systems for plant pathogen (e.g., fungi or fungus-like organisms) assessment and management, and uses thereof, in particular for real-time agricultural applications, are described herein. In embodiments, the method and systems combine the capture of pathogenic spores (e.g., by impaction on an adhesive surface), laboratory analysis to identify the spores (e.g., by microscopy and/or PGR), collecting weather data, determining the level of risk for each pathogen, and providing an output to a user, who may for example access such risk data remotely as a risk report. A weather station is installed in proximity to the field/area where the spore sampling/collection occurs, and allows the constant transfer of weather data to effect the risk assessment. The risk assessment may be used to direct and optimize pesticide (e.g., fungicide) application in accordance with the pathogen identification and assessed risk level.

Abstract: The present invention relates to a method for enhancing growth of plants which comprises contacting a Trichoderma strain with the plant or a plant seed under conditions effective for the Trichoderma strain to colonize the roots of the plant or a plant grown from the plant seed, thereby creating a plant-Trichoderma system. The plant or plant seed is grown under conditions effective to sustain the plant-Trichoderma system in a planting medium and to enhance plant growth, where the Trichoderma strain is selected from the group consisting of Trichoderma atroviride strain WW10TC4 (ATCC accession number PTA 9707), Trichoderma harzianum strain RR17Bc (ATCC accession number PTA 9708), Trichoderma harzianum strain F11Bab (ATCC accession number PTA 9709), and combinations thereof.
