Abstract: Systems and methods for application of active ingredients to plants such as cannabinoid-producing plants (e.g., plants in the genus Cannabis) are generally described. Certain aspects of this disclosure relate to systems for treating cannabinoid-producing plants (e.g., plants of the genus Cannabis such as those containing Cannabis sativa, Cannabis indica, or combinations thereof) involving fluidic communication between the plants and a source of a cyclopropene (e.g., in an enclosure). In some embodiments, cannabinoid-producing plants (e.g., plants of the genus Cannabis) are exposed to a cyclopropene (e.g., 1-methylcyclopropene in a gas phase). Some embodiments involve such exposure inducing potentially desirable phenomena with the plants, such as growth of male sex organs on female plants and/or enhancement of plant biomass.

Abstract: Devices, systems, and methods for releasing active ingredients, including volatile active ingredients, are described. The active ingredients may be released for agricultural applications prior to, during, and/or after harvest of produce. In some instances, the devices, systems, and/or methods promote relatively rapid release of active ingredients from a bed containing a porous and solid delivery material (e.g., a particulate material) via direction of gaseous fluid flow through the bed. For example, a pump (e.g., a fan) connected to a housing comprising the bed may propel gas (e.g., air) through the bed, thereby inducing, maintaining, and/or accelerating release of the active ingredient. In some embodiments, the devices, systems, and/or methods described herein facilitate fast, safe, and efficient fumigation of agricultural and/or horticultural products with active ingredients, before, during, and/or after their harvest.

Abstract: Devices and methods for release and delivery of active ingredients such as sprout suppressants are generally described.

Abstract: Compositions for controlled release of active ingredients and methods of making same are generally provided. In some embodiments, the composition comprises an active ingredient and a delivery material. In some embodiments, the composition comprises a volatile or gaseous active ingredient useful for applications in at least one of agriculture, pest control, odor control, and food preservation. In some embodiments, the active ingredient is a cyclopropene. In some embodiments, the active ingredient is an essential oil, a terpene, or a terpenoid. In some embodiments, the delivery material is a carbon material or a silicate material.

Abstract: Compositions for humidity activated release of antimicrobials, and associated methods, are generally provided. Certain aspects are related to compositions comprising delivery materials (e.g., silica-based delivery materials) and antimicrobials. The delivery material and the antimicrobial can be associated with each other such that when humidity is introduced to the composition, at least a portion of the antimicrobial is released from the composition. Methods of releasing antimicrobials from compositions are also provided. Certain methods comprise allowing antimicrobial to be released from a composition such that the antimicrobial suppresses the actions or adverse effects of pathogens or pests.

Abstract: Systems, compositions, methods, and methods of making compositions for release of one or more cyclopropene compounds are generally provided.
