Abstract
The present invention relates to new, highly efficient synergistic compositions comprising mixtures of essential oils, metal ions, detergents and organic acids in combination with plant protection agents. That is, applied as an adjuvans or additive, said mixtures significantly increase the efficacy and biocompatibility of conventional plant protection agents for plant protection products. The new synergistic composition thereby allows significant reduction of active ingredients of conventional plant protection agents.
Core Innovation
The disclosed invention relates to a synergistic plant protection composition comprising at least one plant protection agent present in a concentration of 0.001% to 0.1% (weight) relative to the total weight of the composition. The plant protection agent is selected from Propamocarb, Prothioconazole, Cymoxanil, Mancozeb, Chlorothalonil, Azoxystrobin, and Copper oxychloride, and the composition further includes a mixture for enhancing at least one activity of the plant protection agent.
The enhancing mixture comprises at least one essential oil, at least one type of organic acid, at least one metal ion, and at least one detergent, with each component defined by concentration ranges in the description. The composition combines conventional plant protection agents with the enhancing mixture to achieve synergistic effects.
The description presents the need to increase antimicrobial efficacy and biocompatibility while enabling a significant reduction of the plant protection agent concentration versus conventional formulations. The partial content supports this concept with an in vitro test system using Candida parapsilosis and Aspergillus niger against various conventional fungicides combined with additive mixtures, where complete synergistic combinations outperform the agents alone and incomplete mixtures.
Claims Coverage
The partial content identifies two independent claims directed to a plant protection composition and a method for enhancing activity. The claim set specifies four additive component types and concentration ranges, and requires the plant protection agent to be one of a defined group of fungicides.
Plant protection composition with synergistic enhancing mixture
A plant protection composition comprising at least one plant protection agent in a concentration of 0.001% to 0.1% (weight) relative to the total weight of the composition, selected from Propamocarb, Prothioconazole, Cymoxanil, Mancozeb, Chlorothalonil, Azoxystrobin, and Copper oxychloride, and a mixture for enhancing at least one activity of the plant protection agent comprising at least one essential oil, at least one type of organic acid, at least one metal ion, and at least one detergent, each defined by concentration ranges within the claim.
Method for enhancing plant protection agent activity with defined mixture
A method for enhancing at least one activity of at least one plant protection agent by adding at least one essential oil, at least one type of organic acid, at least one metal ion, and at least one detergent to said at least one plant protection agent, wherein the plant protection agent is provided in a concentration of 0.001% to 0.1% (weight) and is selected from Propamocarb, Prothioconazole, Cymoxanil, Mancozeb, Chlorothalonil, Azoxystrobin, and Copper oxychloride.
Across the two independent claims, the inventive core is the defined synergistic combination of a conventional plant protection agent, restricted to a named group, with an enhancing mixture comprising essential oil, organic acid, metal ion, and detergent, each present within specified concentration ranges.
Stated Advantages
Increases antimicrobial efficacy.
Improves biocompatibility.
Enables significant reduction of the plant protection agent concentration versus conventional formulations.
Documented Applications
In vitro antimicrobial testing against Candida parapsilosis and Aspergillus niger using conventional fungicides and additive mixtures, with complete synergistic combinations outperforming agents alone and incomplete mixtures.
